## Evaluate TinyLlama

### GPT4All Benchmarks

We evaluate TinyLlama's commonsense reasoning ability following the [GPT4All](https://gpt4all.io/index.html) evaluation suite. We include Pythia as our baseline. We report the acc_norm by default.

We observed huge improvements once we finetuned the model. We attribute this phenomenon to: 1. the base model has not undergone lr cool-down and FT helps to cool down the lr. 2. the SFT stage better elicits the model's internal knowledge.

You can obtain the above scores by running [lm-eval-harness](https://github.com/EleutherAI/lm-evaluation-harness):
```bash
python main.py \
    --model hf-causal \
    --model_args pretrained=PY007/TinyLlama-1.1B-Chat-v0.1,dtype="float" \
    --tasks hellaswag,openbookqa,winogrande,arc_easy,arc_challenge,boolq,piqa\
    --device cuda:0 --batch_size 32
```



### Instruct-Eval Benchmarks
We evaluate TinyLlama's ability in problem-solving on the [Instruct-Eval](https://github.com/declare-lab/instruct-eval) evaluation suite.
