EditCoder

The EditCoder models are the fine-tuned models described in the following paper:

}

This repository has several models. The root is the fine-tune of DeepSeek Coder 33B on the EditPackFT dataset. The other models are in subdirectories. You can do this:

AutoModelForCausalLM.from_pretrained("nuprl/EditCoder", subfolder=DIR_NAME)

Prompt

The model has been trained on the following prompt format:

## Code Before:
{before}
## Instruction:
{instruction}
## Code After:
{after}

Here is a python function that can be used for formatting the prompt correctly:

def edit_prompt(old, instr):
    before = f"""## Code Before:\n{old}\n"""
    instr = f"""## Instruction:\n{instr}\n"""
    after = f"""## Code After:\n"""
    return before + instr + after

Training Code

We provide the full pipeline that was used for training our own edit-coder model. The pipeline and instructions can be found on our GitHub repository.
