StarCoder-1b-textbook

StarCoder-1b-textbook is a finetuned version of starcoderbase-1b on the code_exercices dataset

It achieves 27.0 pass@1 on the Human Eval coding benchmark while being only 1b parameters. That is an improvement of almost 12 points over the starcoder 1b baseline, almost doubling the score.

The results (on the human eval benchmark) are on par with other open-source models like StarCoderBase (30.4) StarCoder(33.6) CodeGen-16B-Mono(29.3) while the model being 15 times smaller.

It still underperforms compared to other models like CodeLLama (53%) chat gpt 4 (82) or wizard coder (73.2), but these model are more than 30 times bigger.

Usage

You can download and use the model like so:

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
        "jinaai/starcoder-1b-textbook", device_map='auto'
    )

tokenizer = AutoTokenizer.from_pretrained("jinaai/starcoder-1b-textbook")

prompt = '''
def unique(l: list):
    """Return sorted unique elements in a list
    >>> unique([5, 3, 5, 2, 3, 3, 9, 0, 123])
    [0, 2, 3, 5, 9, 123]
    """
'''

inputs = tokenizer(prompt.rstrip(), return_tensors="pt").to("cuda")

generation_output = model.generate(
    **inputs,
    max_new_tokens=128,
    eos_token_id=tokenizer.eos_token_id,
    return_dict_in_generate=True,
)

s = generation_output.sequences[0]
output = tokenizer.decode(s, skip_special_tokens=True)

print(output)

Finetuning details

We did full parameter fine-tuning and used a Nvidia a40 for 12 hours using a batch size of 128 and a micro-batch size of 8.

To reproduce the training just follow the training instructions in our open source codebase

Disclaimer

• The human eval benchmark is not a perfect benchmark and does not fully represent the coding abilities of an LLM. This model performs well on the task described in the benchmark but it does not necessarily mean that our model is on par with bigger models on coding assistant LLM.
• This model is not an instruction tuned model and cannot be used as a chatbot. We recommend using the Evol-Instruct-Code-80k-v1 to finetune it into a instrution following model
• This model has not been aligned with human preferences and therefore could potentially generate harmful content
• This model has been trained on a dataset generated by ChatGPT 3.5, and you should check the legal status of AI-generated content in your jurisdiction before using it. You should make sure that your usage complies with the OpenAI Terms of Use, in so far as legally applicable.
