Model Summary

Astraios-Parallel Adapter is an instruction tuned model with 15.5B parameters created by finetuning StarCoderBase on CommitPackFT & OASST as described in the Astraios paper.

Repository: bigcode-project/astraios
Paper: Astraios: Parameter-Efficient Instruction Tuning Code Large Language Models
Languages: 80+ Programming languages
✨Astraios:

Data	CommitPackFT+OASST	Filtered version of CommitPack and OASST for high-quality commit messages that resemble instructions
Model	Astraios-1B	Collection of StarCoderBase-1B models instruction tuned on CommitPackFT + OASST with different tuning methods
	Astraios-3B	Collection of StarCoderBase-3B (3B parameters) models instruction tuned on CommitPackFT + OASST with different tuning methods
	Astraios-7B	Collection of StarCoderBase-7B (7B parameters) models instruction tuned on CommitPackFT + OASST with different tuning methods
	Astraios-16B	Collection of StarCoderBase-16B (16B parameters) models instruction tuned on CommitPackFT + OASST with different tuning methods
Evaluation	BigCloneBench	Dataset for clone detection; We use 2,000 samples for evaluation
	Devign	Dataset for defect detection; We use 2,000 samples for evaluation
	HumanEvalPack	Extension of OpenAI's HumanEval to cover 3 scenarios across 6 languages
	ReCode	Dataset for the robustness of code generation, covering 4 variants
	Asleep At The Keyboard	Datasets for security of code generation; We use DoW for evaluation

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.

Answer:"

Generation

python

# pip install -q transformers
# pip install -e git+https://github.com/bigcode-project/astraios#subdirectory=peft
from peft import PeftModel 
from transformers import AutoModelForCausalLM, AutoTokenizer

peft_checkpoint = "bigcode/astraios-parallel"
checkpoint = "bigcode/starcoderbase"
model = AutoModelForCausalLM.from_pretrained(checkpoint)
model = PeftModel.from_pretrained(model, peft_checkpoint)
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.

Answer:", return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))
