# **Quantization summary**

The base model was quantized in [llama.cpp](https://github.com/ggerganov/llama.cpp) with a substantive importance matrix over all target languages (some 34x1000 samples, 96MB of text) with samples from the [Open Super-large Crawled ALMAnaCH coRpus](/datasets/oscar-corpus/oscar) dataset. Logs of the process are included.

- **IQ3_M**: At <1.8GB, the smallest model worth highlighting.
- **IQ4_XS** or **Q4_K_S**: Its a toss up for the sub-2GB quantizations. Metal users will get more t/s from Q4_K_S.
- **Q5_K_M**: Excellent balance above **Q4**, recommended for most applications.
- **Q6_K**: Provides near-**bf16** performance with size savings.

# Quantization

| **Quantization Type** | **PPL(Q)** | **ln(PPL(Q)/PPL(bf16))** | **File Size (G)** | **Notes**                                                      |
|-----------------------|------------|------------------------|-------------------|----------------------------------------------------------------|
| [**IQ3_M**](salamandra-2b-instruct_IQ3_M.gguf)             | 16.774     | 0.086769               | 1.7               | Good size efficiency with acceptable PPL increase              |
| [**Q3_K_L**](salamandra-2b-instruct_Q3_K_L.gguf)            | 16.5067    | 0.070705               | 1.8               | Further size reduction with modest PPL increase                |
| [**IQ4_XS**](salamandra-2b-instruct_IQ4_XS.gguf)            | 15.9591 | 0.036968            | 1.8           | Good size reduction with acceptable PPL increase (**recommended**)              |
| [**Q4_K_S**](salamandra-2b-instruct_Q4_K_S.gguf)            | 15.9346    | 0.035431               | 1.9               | Good size reduction with minimal PPL impact (**recommended**)  |
| [**Q5_K_M**](salamandra-2b-instruct_Q5_K_M.gguf)            | 15.4746    | 0.006139               | 2.2               | Excellent balance of PPL and size (**recommended**)            |
| [**Q6_K**](salamandra-2b-instruct_Q6_K.gguf)                | 15.3961    | 0.001053               | 2.4               | Nearly lossless performance with reduced size                  |
| [**bf16**](salamandra-2b-instruct_bf16.gguf)                | 15.3799    | 0.000000               | 4.2               | Baseline                                                       |

### **Notes:**

- **Recommended Quantizations:**
  - **IQ4_XL:** A good size reduction with minimal PPL impact. The filesize is actually very close to 1.9GB, so not much different from Q4_K_S.
  - **Q4_K_S:** A good size reduction with minimal PPL impact.
  - **Q5_K_M:** Offers the best balance between low perplexity and reduced file size above Q4, making it ideal for most applications.
- **Non-recommended Quantizations:**
  - **IQ3_M:** Represents the best of the I quantization types below Q4, achieving good size efficiency while maintaining low perplexity.
  - **Q3_K_L:** Provides a slightly larger file size (1.8G) with an acceptable PPL (16.5067). While it meets the log PPL difference criteria, it is not as balanced as the recommended quantizations.
  - **Q6_K:** Delivers nearly lossless performance compared to bf16 with a reduced file size (2.4G vs. 4.2G). Ideal for scenarios requiring maximum accuracy with some size savings.
- An attempt was made to get a model below **IQ3_M** size, but perplexity was unacceptable even with **IQ2_M** (more than the 0.3 selection crteria, see next section). If you need a model below 1.7GB, you may be better served by Richard Erkhov's [quantizations](https://huggingface.co/RichardErkhov/BSC-LT_-_salamandra-2b-instruct-gguf), which seem to be a static quantization instead of using an importance matrix, so they are smaller.

---

### **Defending the Selection:**

The selection of recommended models is designed to provide a spectrum of options that meet the following criteria:

- **Diversity in Quantization Types:**
  - **I Quantization Below Q4:** **IQ3_M** is included to offer an option that uses I quantization below the **Q4** level, balancing size and performance.
  - **K Quantization At and Above Q4:** **Q4_K_S**, **Q4_K_M**, **Q5_K_M**, and **Q6_K** provide K quantization options at and above the **Q4** level, giving users choices based on their specific needs.
  - **Highly Compressed Quantization (Q3 and below):** **IQ3_M** and **Q3_K_L** are included as they meet the selection criteria of log PPL diff <0.3 and are not redundant with other models.

- **Selection Criteria:**
  - **Log PPL diff <0.3:** All included models have a log PPL difference under 0.3, ensuring that they maintain acceptable performance even when highly quantized.
  - **No Multiple Models Within 100MB of the Same File Size:** Only one model is included per similar file size range to avoid redundancy. For example, **Q3_K_L** (1.8G) is included while other models like **Q3_K_M** (1.7G) are excluded due to nearly equal file sizes and differing PPL, ensuring a sparse yet comprehensive selection.

PPL is measured from a sample of 50 of each language from the same dataset used to calculate the importance matrix.

# Comparison of salamandra 2b/instruct quantization results

![](./images/comparison_of_quantization.png)

Between the two runs, sost shared quantization types show consistent behavior across both models, reinforcing the reliability of these quantization schemes irrespective of fine-tuning. The 2b instruct quantizations showed a slight upward shift, indicating marginally higher loss for equivalent quantizations.

## Intended Use

### Direct Use

The models are intended for both research and commercial use in any of the languages included in the training data. 
The base models are intended either for language generation or to be further fine-tuned for specific use-cases. 
The instruction-tuned variants can be used as general-purpose assistants, as long as the user is fully aware of the model’s limitations.

### Out-of-scope Use

The model is not intended for malicious activities, such as harming others or violating human rights. 
Any downstream application must comply with current laws and regulations. 
Irresponsible usage in production environments without proper risk assessment and mitigation is also discouraged. 

---

## Hardware and Software

### Training Framework

Pre-training was conducted using NVIDIA’s [NeMo Framework](https://docs.nvidia.com/nemo-framework/index.html), 
which leverages PyTorch Lightning for efficient model training in highly distributed settings.

The instruction-tuned versions were produced with [FastChat](https://github.com/lm-sys/FastChat).

### Compute Infrastructure

All models were trained on [MareNostrum 5](https://www.bsc.es/ca/marenostrum/marenostrum-5), a pre-exascale EuroHPC supercomputer hosted and
operated by Barcelona Supercomputing Center.

The accelerated partition is composed of 1,120 nodes with the following specifications:
- 4x Nvidia Hopper GPUs with 64 HBM2 memory
- 2x Intel Sapphire Rapids 8460Y+ at 2.3Ghz and 32c each (64 cores)
- 4x NDR200 (BW per node 800Gb/s)
- 512 GB of Main memory (DDR5)
- 460GB on NVMe storage

|Model|Nodes|GPUs|
|:---:|:---:|:---:|
|2B|64|256|
|7B|128|512|
|40B|256 / 512|1,024 / 2,048|

## How to use

The instruction-following models use the commonly adopted ChatML template:

```jinja
{%- if not date_string is defined %}{%- set date_string = "2024-09-30" %}{%- endif %}{{ "<|im_start|>system\nsystem_message\nToday Date: "+ date_string +"<|im_end|>\n" }}{% for message in messages %}{{'<|im_start|>' + message['role'] + '\n' + message['content'] + '<|im_end|>' + '\n'}}{% endfor %}{% if add_generation_prompt %}{{ '<|im_start|>assistant\n' }}{% endif %}
```
Where `system_message` is used to guide the model during generation and `date_string` can be set to allow the model to respond with the current date.

The exact same chat template should be used for an enhanced conversational experience.
The easiest way to apply it is by using the tokenizer's built-in functions, as shown in the following snippet.

```python
from datetime import datetime
from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

model_id = "BSC-LT/salamandra-2b-instruct"

text = "At what temperature does water boil?"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    device_map="auto",
    torch_dtype=torch.bfloat16
  )

message = [ { "role": "user", "content": text } ]
date_string = datetime.today().strftime('%Y-%m-%d')

prompt = tokenizer.apply_chat_template(
    message,
    tokenize=False,
    add_generation_prompt=True,
    date_string=date_string
)

inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")
outputs = model.generate(input_ids=inputs.to(model.device), max_new_tokens=200)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
Using this template, each turn is preceded by a `<|im_start|>` delimiter and the role of the entity 
(either `user`, for content supplied by the user, or `assistant` for LLM responses), and finished with the `<|im_end|>` token.

## Data

### Pretraining Data

The training corpus consists of 2.4 trillion tokens, including 35 European languages and 92 programming languages. It amounts to a total of 33TB of pre-processed text. 
Languages were sampled manually by giving x2 oversampling to Spain's co-official languages (Spanish, Catalan, Galician and Basque), code was undersampled by half, 
and the rest of the languages were kept as is, resulting in the following distribution:

![lang distrib](./images/corpus_languages.png)

This highly multilingual corpus is predominantly composed of data from Colossal OSCAR, 
which contributes a significant 66.06% of the total tokens. 
Following this, Starcoder provides 11.91%, and Spanish Crawling adds 3.34%. 
The next largest sources are French FR at 3.12% and Proof Pile at 1.98%. 
Other notable contributions include Macocu, Pile of Law, and Eurlex, each contributing around 1.5% to 1.3%. 
These major sources collectively form the bulk of the corpus, ensuring a rich and diverse dataset for training the language model.
The remaining 10% comes from smaller sources in various languages.

The model was trained for 3 epochs, with two final rounds of 0.3B higher-quality tokens each, 
meaning that the total number of tokens seen during pre-training amounts to roughly 7.8 trillion tokens.

We provide an extense Datasheet section following the best practices defined by [(Gebru et al., 2021)](https://arxiv.org/pdf/1803.09010).

<details>
<summary>Datasheet</summary>

#### Motivation

**For what purpose was the dataset created? Was there a specific task in mind? Was there a specific gap that needed to be filled? Please provide a description.**

The purpose of creating this dataset is to pre-train the Salamandra family of multilingual models with high performance in a large number of 
European languages (35) and code (including 92 different programming languages). In addition, we aim to represent especially the co-official 
languages of Spain: Spanish, Catalan, Galician, and Basque. This is the reason why we carry out an oversampling of these languages.

We detected that there is a great lack of massive multilingual data, especially in minority languages (Ostendorff & Rehm, 2023), so part of 
our efforts in the creation of this pre-training dataset have resulted in the contribution to large projects such as the Community OSCAR 
(Brack et al., 2024), which includes 151 languages and 40T words, or CATalog (Palomar-Giner et al., 2024), the largest open dataset in 
Catalan in the world.

**Who created the dataset (e.g., which team, research group) and on behalf of which entity (e.g., company, institution, organization)?**

The dataset has been created by the Language Technologies unit (LangTech) of the Barcelona Supercomputing Center - Centro Nacional de 
Supercomputación (BSC-CNS), which aims to advance the field of natural language processing through cutting-edge research and development 
and the use of HPC. In particular, it was created by the unit's data team, the main contributors being Javier Saiz, Ferran Espuña, and 
Jorge Palomar.

However, the creation of the dataset would not have been possible without the collaboration of a large number of collaborators, partners, 
and public institutions, which can be found in detail in the acknowledgements.

**Who funded the creation of the dataset? If there is an associated grant, please provide the name of the grantor and the grant name and number.**

This work/research has been promoted and financed by the Government of Catalonia through the [Aina project](https://projecteaina.cat/).

#### Composition

**What do the instances that comprise the dataset represent (e.g., documents, photos, people, countries)? Are there multiple types of instances (e.g., movies, users, and ratings; people and interactions between them; nodes and edges)? Please provide a description.**

The dataset consists entirely of text documents in various languages. Specifically, data was mainly sourced from the following databases and 
repositories:
- **Common Crawl:** Repository that holds website data and is run by the Common Crawl non-profit organization. It is updated monthly and is
  distributed under the CC0 1.0 public domain license.
- **GitHub:** Community platform that allows developers to create, store, manage, and share their code. Repositories are crawled and then
  distributed with their original licenses, which may vary from permissive to non-commercial licenses.
- **Wikimedia:** Database that holds the collection databases managed by the Wikimedia Foundation, including Wikipedia, Wikibooks, Wikinews,
  Wikiquote, Wikisource, and Wikivoyage. It is updated monthly and is distributed under Creative Commons Attribution-ShareAlike License 4.0.
- **EurLex:** Repository that holds the collection of legal documents from the European Union, available in all of the EU’s 24 official
  languages and run by the Publications Office of the European Union. It is updated daily and is distributed under the Creative Commons
  Attribution 4.0 International license.
- **Other repositories:** Specific repositories were crawled under permission for domain-specific corpora, which include academic, legal,
  and newspaper repositories.

We provide a complete list of dataset sources at the end of this section.

**How many instances are there in total (of each type, if appropriate)?**

The dataset contains a diverse range of instances across multiple languages, with notable adjustments for certain languages. English 
represents the largest portion, accounting for 39.08% of the total data. Spanish was upsampled by a factor of 2, bringing its share to 16.59%,
while Catalan (1.84%), Basque (0.26%), and Galician (0.36%) were also upsampled by 2. On the other hand, code-related data was downsampled 
by half, making up 6.42% of the total. Other prominent languages include French (6.59%), Russian (5.39%), German (4.25%), and Hungarian 
(3.93%), with several additional languages contributing between 1% and 2%, and smaller portions represented by a variety of others.

**Does the dataset contain all possible instances or is it a sample (not necessarily random) of instances from a larger set? If the dataset is a sample, then what is the larger set? Is the sample representative of the larger set (e.g., geographic coverage)? If so, please describe how this representativeness was validated/verified. If it is not representative of the larger set, please describe why not (e.g., to cover a more diverse range of instances, because instances were withheld or unavailable).**

The dataset is a sample from multiple sources, with different weights based on the primary language of the content: Spanish, Catalan, 
Basque, and Galician content was upsampled by a factor of two, while programming languages were downsampled by a factor of half. Other 
sources were sampled in proportion to their occurrence.

**What data does each instance consist of? “Raw” data (e.g., unprocessed text or images) or features? In either case, please provide a description.**

Each instance consists of a text document processed for deduplication, language identification, and source-specific filtering. Some 
documents required optical character recognition (OCR) to extract text from non-text formats such as PDFs.

**Is there a label or target associated with each instance? If so, please provide a description.**

Each instance is labeled with a unique identifier, the primary language of the content, and the URL for web-sourced instances. Additional 
labels were automatically assigned to detect specific types of content —harmful or toxic content— and to assign preliminary indicators of 
undesired qualities —very short documents, high density of symbols, etc.— which were used for filtering instances.

**Is any information missing from individual instances? If so, please provide a description, explaining why this information is missing (e.g., because it was unavailable). This does not include intentionally removed information, but might include, e.g., redacted text.**

No significant information is missing from the instances.

**Are relationships between individual instances made explicit (e.g., users’ movie ratings, social network links)? If so, please describe how these relationships are made explicit.**

Instances are related through shared metadata, such as source and language identifiers.

**Are there recommended data splits (e.g., training, development/validation, testing)? If so, please provide a description of these splits, explaining the rationale behind them.**

The dataset is split randomly into training, validation, and test sets.

**Are there any errors, sources of noise, or redundancies in the dataset? If so, please provide a description.**

Despite removing duplicated instances within each source, redundancy remains at the paragraph and sentence levels, particularly in 
web-sourced instances where SEO techniques and templates contribute to repeated textual patterns. Some instances may also be duplicated 
across sources due to format variations.

**Is the dataset self-contained, or does it link to or otherwise rely on external resources (e.g., websites, tweets, other datasets)? If it links to or relies on external resources, a) are there guarantees that they will exist, and remain constant, over time; b) are there official archival versions of the complete dataset (i.e., including the external resources as they existed at the time the dataset was created); c) are there any restrictions (e.g., licenses, fees) associated with any of the external resources that might apply to a dataset consumer? Please provide descriptions of all external resources and any restrictions associated with them, as well as links or other access points, as appropriate.**

The dataset is self-contained and does not rely on external resources.

**Does the dataset contain data that might be considered confidential (e.g., data that is protected by legal privilege or by doctor–patient confidentiality, data that includes the content of individuals’ non-public communications)? If so, please provide a description.**

The dataset does not contain confidential data.

**Does the dataset contain data that, if viewed directly, might be offensive, insulting, threatening, or might otherwise cause anxiety? If so, please describe why. If the dataset does not relate to people, you may skip the remaining questions in this section.**

The dataset includes web-crawled content, which may overrepresent pornographic material across languages (Kreutzer et al., 2022). Although 
pre-processing techniques were applied to mitigate offensive content, the heterogeneity and scale of web-sourced data make exhaustive 
filtering challenging, which makes it next to impossible to identify all adult content without falling into excessive filtering, which may 
negatively influence certain demographic groups (Dodge et al., 2021).

**Does the dataset identify any subpopulations (e.g., by age, gender)? If so, please describe how these subpopulations are identified and provide a description of their respective distributions within the dataset.**

The dataset does not explicitly identify any subpopulations.

**Is it possible to identify individuals (i.e., one or more natural persons), either directly or indirectly (i.e., in combination with other data) from the dataset? If so, please describe how.**

Web-sourced instances in the dataset may contain personally identifiable information (PII) that is publicly available on the Web, such as 
names, IP addresses, email addresses, and phone numbers. While it would be possible to indirectly identify individuals through the 
combination of multiple data points, the nature and scale of web data makes it difficult to parse such information. In any case, efforts are 
made to filter or anonymize sensitive data during pre-processing, but some identifiable information may remain in the dataset.

**Does the dataset contain data that might be considered sensitive in any way? If so, please provide a description.**

Given that the dataset includes web-sourced content and other publicly available documents, instances may inadvertently reveal financial 
information, health-related details, or forms of government identification, such as social security numbers (Subramani et al., 2023), 
especially if the content originates from less-regulated sources or user-generated platforms. 

#### Collection Process

**How was the data collected?**

This dataset is constituted by combining several sources, whose acquisition methods can be classified into three groups:
- Web-sourced datasets with some preprocessing available under permissive license (p.e. Common Crawl).
- Domain-specific or language-specific raw crawls (p.e. Spanish Crawling).
- Manually curated data obtained through collaborators, data providers (by means of legal assignment agreements) or open source projects
  (p.e. CATalog).

**What mechanisms or procedures were used to collect the data? How were these mechanisms or procedures validated?**

According to the three groups previously defined, these are the mechanisms used in each of them:
- Open direct download. Validation: data integrity tests. 
- Ad-hoc scrapers or crawlers. Validation: software unit and data integrity tests.
- Direct download via FTP, SFTP, API or S3. Validation: data integrity tests. 

**If the dataset is a sample from a larger set, what was the sampling strategy?**

The sampling strategy was to use the whole dataset resulting from the filtering explained in the ‘preprocessing/cleaning/labelling’ section, 
with the particularity that an upsampling of 2 (i.e. twice the probability of sampling a document) was performed for the co-official 
languages of Spain (Spanish, Catalan, Galician, Basque), and a downsampling of 1/2 was applied for code (half the probability of sampling a 
code document, evenly distributed among all programming languages).

**Who was involved in the data collection process and how were they compensated?**

This data is generally extracted, filtered and sampled by automated processes. The code required to run these processes has been developed 
entirely by members of the LangTech data team, or otherwise obtained from open-source software. Furthermore, there has been no monetary 
consideration for acquiring data from suppliers.

**Over what timeframe was the data collected? Does this timeframe match the creation timeframe of the data associated with the instances? If not, please describe the timeframe in which the data associated with the instances was created.**

Data were acquired and processed from April 2023 to April 2024. However, as mentioned, much data has been obtained from open projects such 
as Common Crawl, which contains data from 2014, so it is the end date (04/2024) rather than the start date that is important.

**Were any ethical review processes conducted? If so, please provide a description of these review processes, including the outcomes, as well as a link or other access point to any supporting documentation.**

No particular ethical review process has been carried out as the data is mostly open and not particularly sensitive. However, we have an 
internal evaluation team and a bias team to monitor ethical issues. In addition, we work closely with ‘Observatori d'Ètica en Intel·ligència 
Artificial’ (OEIAC) and  ‘Agencia Española de Supervisión de la Inteligencia Artificial’ (AESIA) to audit the processes we carry out from an 
ethical and legal point of view, respectively.

#### Preprocessing

**Was any preprocessing/cleaning/labeling of the data done? If so, please provide a description. If not, you may skip the remaining questions in this section.**

Instances of text documents were not altered, but web-sourced documents were filtered based on specific criteria along two dimensions:
- Quality: documents with a score lower than 0.8, based on undesired qualities, such as documents with low number of lines, very short
  sentences, presence of long footers and headers, and high percentage of punctuation, obtained through CURATE (Palomar-Giner et al., 2024)
  were filtered out.
- Harmful or adult content: documents originating from Colossal OSCAR were filtered using LLM-Datasets (Ostendorff et al., 2024) based on
  the perplexity from a language model (‘harmful_pp’ field) provided by the Ungoliant pipeline (Abadji et al., 2021).

**Was the “raw” data saved in addition to the preprocessed/cleaned/labeled data? If so, please provide a link or other access point to the “raw” data.**

The original raw data was not kept.

**Is the software that was used to preprocess/clean/label the data available? If so, please provide a link or other access point.**

Yes, the preprocessing and filtering software is open-sourced. The [CURATE](https://github.com/langtech-bsc/CURATE) pipeline was used for Spanish Crawling and CATalog, 
and the [Ungoliant](https://github.com/oscar-project/ungoliant) pipeline was used for the OSCAR project.

#### Uses

**Has the dataset been used for any tasks already? If so, please provide a description.**

Pre-train the Salamandra model family.

**What (other) tasks could the dataset be used for?**

The data can be used primarily to pre-train other language models, which can then be used for a wide range of use cases. The dataset could 
also be used for other tasks such as fine-tuning language models, cross-lingual NLP tasks, machine translation, domain-specific text 
generation, and language-specific data analysis.

**Is there anything about the composition of the dataset or the way it was collected and preprocessed/cleaned/labeled that might impact future uses? Is there anything a dataset consumer could do to mitigate these risks or harms?**
 
Web-crawled content is over-represented with standard language varieties, impacting language model performance for minority languages. 
Language diversity in data is crucial to avoid bias, especially in encoding non-standard dialects, preventing the exclusion of demographic 
groups. Moreover, despite legal uncertainties in web-scraped data, we prioritize permissive licenses and privacy protection measures, 
acknowledging the challenges posed by personally identifiable information (PII) within large-scale datasets. Our ongoing efforts aim to 
address privacy concerns and contribute to a more inclusive linguistic dataset.

**Are there tasks for which the dataset should not be used?**

-

#### Distribution 

**Will the dataset be distributed to third parties outside of the entity on behalf of which the dataset was created? If so, please provide a description.**

The dataset will not be released or distributed to third parties. Any related question to distribution is omitted in this section.

#### Maintenance

**Who will be supporting/hosting/maintaining the dataset?**

The dataset will be hosted by the Language Technologies unit (LangTech) of the Barcelona Supercomputing Center (BSC). The team will ensure 
regular updates and monitor the dataset for any issues related to content integrity, legal compliance, and bias for the sources they are 
responsible for.

**How can the owner/curator/manager of the dataset be contacted?**

The data owner may be contacted with the email address [email protected].

**Will the dataset be updated?**

The dataset will not be updated.

**If the dataset relates to people, are there applicable limits on the retention of the data associated with the instances? If so, please describe these limits and explain how they will be enforced.**

The dataset does not keep sensitive data that could allow direct identification of individuals, apart from the data that is publicly 
available in web-sourced content. Due to the sheer volume and diversity of web data, it is not feasible to notify individuals or manage data 
retention on an individual basis. However, efforts are made to mitigate the risks associated with sensitive information through 
pre-processing and filtering to remove identifiable or harmful content. Despite these measures, vigilance is maintained to address potential 
privacy and ethical issues.

**Will older versions of the dataset continue to be supported/hosted/maintained? If so, please describe how. If not, please describe how its obsolescence will be communicated to dataset consumers.**

Since the dataset will not be updated, only the final version will be kept.

**If others want to extend/augment/build on/contribute to the dataset, is there a mechanism for them to do so?**

The dataset does not allow for external contributions.

## Evaluation

### Gold-standard benchmarks

Evaluation is done using the Language Model Evaluation Harness (Gao et al., 2024). We evaluate on a set of tasks taken from [SpanishBench](https://github.com/EleutherAI/lm-evaluation-harness/tree/main/lm_eval/tasks/spanish_bench), [CatalanBench](https://github.com/EleutherAI/lm-evaluation-harness/tree/main/lm_eval/tasks/catalan_bench), [BasqueBench](https://github.com/EleutherAI/lm-evaluation-harness/tree/main/lm_eval/tasks/basque_bench) and [GalicianBench](https://github.com/EleutherAI/lm-evaluation-harness/tree/main/lm_eval/tasks/galician_bench). These benchmarks include both new and existing tasks and datasets. Given that this is an instructed model, we add LM Evaluation Harness's native feature of `chat-template` to the setup. In the tables below, we include the results in a selection of evaluation datasets that represent model's performance across a variety of tasks within these benchmarks. 

We only use tasks that are either human generated, human translated, or with a strong human-in-the-loop (i.e., machine translation followed by professional revision or machine generation followed by human revision and annotation). This is the reason behind the variety in number of tasks reported across languages. As more tasks that fulfill these requirements are published, we will update the presented results. We also intend to expand the evaluation to other languages, as long as the datasets meet our quality standards.

During the implementation of the evaluation we observed a series of issues worth considering when replicating and interpreting the results presented. These issues include ≈1.5% variances in performance in some tasks depending on the version of the `transformers` library used, and depending on the use (or lack of use) of tensor parallelism when loading a model. When implementing existing tasks, we carry out a comprehensive quality evaluation of the dataset, the Harness task itself, and what kind of input models see during evaluation. Our implementation (see links above) addresses multiple existing problems such as errors in datasets and prompts, and lack of pre-processing. All this means that results will vary if using other Harness implementations, and may slightly vary depending on the replication setup.

It should be noted that these results are subject to all the drawbacks of every current gold-standard evaluation, and that the figures do not fully represent the models capabilities and potential. We thus advise caution when reading and interpreting the results.

A full list of results compared to other baselines, a discussion of the model's performance across tasks and its implications, and details regarding problem-solving with task implementation will soon be available in the technical report.

All results reported below are on a 0-shot setting.

## Ethical Considerations and Limitations

We examine the presence of undesired societal and cognitive biases present in this model using different benchmarks. For societal biases, we test performance using the BBQ dataset (Parrish et al., 2022) in the original English and the Regard dataset (Sheng et al., 2019). We report that moderate  accuracies (between 0.5 and 0.6 depending on the social groups) in disambiguated settings, the model performs very poorly in ambiguous setting. Taken together, these results suggest the pervasiveness of social biases that may have an effect on task performance

Our cognitive bias analysis focuses on positional effects in 0-shot settings, and majority class bias in few-shot settings. For positional effects, we leverage the ARC Multiple Choice Question dataset (Clark et al., 2018). We observe significant, but moderate weak primacy effects, whereby the model shows a preference for answers towards the beginning of the list of provided answers. We measure effects of majority class effects in few-shot settings using SST-2 (Socher et al., 2013). We again detect significant effects, with a small effect size. This suggests that the model is relatively robust against the examined cognitive biases.

We highlight that our analyses of these biases are by no means exhaustive and are limited by the relative scarcity of adequate resources in all languages present in the training data. We aim to gradually extend and expand our analyses in future work.

These results can be expected from a model that has undergone only a preliminary instruction tuning. These tests are performed in order to show the biases the model may contain. We urge developers to take them into account and perform safety testing and tuning tailored to their specific applications of the model.
