Model Summary

OctoCoder is an instruction tuned model with 15.5B parameters created by finetuning StarCoder on CommitPackFT & OASST as described in the OctoPack paper.

• Repository: bigcode-project/octopack
• Paper: OctoPack: Instruction Tuning Code Large Language Models
• Languages: 80+ Programming languages
• OctoPack🐙🎒:

  Data	CommitPack	4TB of GitHub commits across 350 programming languages
  	CommitPackFT	Filtered version of CommitPack for high-quality commit messages that resemble instructions
  Model	OctoCoder	StarCoder (16B parameters) instruction tuned on CommitPackFT + OASST
  	OctoGeeX	CodeGeeX2 (6B parameters) instruction tuned on CommitPackFT + OASST
  Evaluation	HumanEvalPack	Extension of OpenAI's HumanEval to cover 3 scenarios across 6 languages

Use

Intended use

The model follows instructions provided in the input. You should always preface your input with "Question: " and finish it with "Answer:", for example: "Question: Please write a function in Python that performs bubble sort.\n\nAnswer:"

Feel free to share your generations in the Community tab!

Generation

# pip install -q transformers
from transformers import AutoModelForCausalLM, AutoTokenizer

checkpoint = "bigcode/octocoder"
device = "cuda" # for GPU usage or "cpu" for CPU usage

tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint).to(device)

inputs = tokenizer.encode("Question: Please write a function in Python that performs bubble sort.\n\nAnswer:", return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))
