## Mistral 7B fine-tuned on LIMA
This model is a fine-tuned version of [mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) on the [LIMA](https://huggingface.co/datasets/GAIR/lima) dataset for instruction following downstream task.
## Training procedure
The model was loaded on **8 bits** and fine-tuned on the LIMA dataset using the **LoRA** PEFT technique with the `huggingface/peft` library and `trl/sft` for 2 epochs on 1 x A100 (40GB) GPU.
SFT Trainer params:
```
trainer = SFTTrainer(
model=model,
train_dataset=train_ds,
eval_dataset=test_ds,
peft_config=peft_config,
dataset_text_field="text",
max_seq_length=2048,
tokenizer=tokenizer,
args=training_arguments,
packing=False
)
```
LoRA config:
```
config = LoraConfig(
lora_alpha=16,
lora_dropout=0.1,
r=64,
bias="none",
task_type="CAUSAL_LM",
target_modules = ['q_proj', 'k_proj', 'down_proj', 'v_proj', 'o_proj', 'gate_proj', 'up_proj']
)
```
