# K2: a fully-reproducible large language model outperforming Llama 2 70B using 35% less compute |
|
|
|
LLM360 demystifies the training recipe used for Llama 2 70B with K2. K2 is fully transparent, meaning we’ve open-sourced all artifacts, including code, data, model checkpoints, intermediate results, and more. |

|
## About K2: |
|
* 65 billion parameter LLM |
|
* Tokens: 1.4T |
|
* Languages: English |
|
* Models Released: base, chat model |
|
* Trained in 2 stages |
|
* License: Apache 2.0 |
|
|
|
K2 was developed as a collaboration between [MBZUAI](https://mbzuai.ac.ae/institute-of-foundation-models/), [Petuum](petuum.com), and [LLM360](llm360.ai). |
|
|
|
## LLM360 Model Performance and Evaluation Collection |
|
|
|
The LLM360 Performance and Evaluation Collection is a robust evaluations set consisting of general and domain specific evaluations to assess model knowledge and function. |
|
|
|
|
|
Evaluations include standard best practice benchmarks, medical, math, and coding knowledge. More about the evaluations can be found [here](llm360.ai/evaluations). |

|
|
Detailed analysis can be found on the K2 Weights and Biases project [here](https://wandb.ai/llm360/K2?nw=29mu6l0zzqq) |
|
|
|
|
|
## K2 Gallery |
|
The K2 gallery allows one to browse the output of various prompts on intermediate K2 checkpoints, which provides an intuitive understanding on how the model develops and improves over time. This is inspired by The Bloom Book. |

|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("LLM360/K2") |
|
model = AutoModelForCausalLM.from_pretrained("LLM360/K2") |
|
|
|
prompt = 'what is the highest mountain on earth?' |
|
|
|
input_ids = tokenizer(prompt, return_tensors="pt").input_ids |
|
gen_tokens = model.generate(input_ids, do_sample=True, max_new_tokens=128) |

## About LLM360 |
|
LLM360 is an open research lab enabling community-owned AGI through open-source large model research and development. |
|
|
|
|
|
LLM360 enables community-owned AGI by creating standards and tools to advance the bleeding edge of LLM capability and empower knowledge transfer, research, and development. |
|
|
|
We believe in a future where artificial general intelligence (AGI) is created by the community, for the community. Through an open ecosystem of equitable computational resources, high quality data, and flowing technical knowledge, we can ensure ethical AGI development and universal access for all innovators. |
