AXIOM-coder-9B

AXIOM is a private, open coding assistant built by Leslie Moody — a Yi-Coder 9B model fine-tuned (QLoRA) on Leslie's own code plus a Python coding-instruction dataset, then merged and quantized to GGUF (Q4_K_M) so it runs fully locally and privately through Ollama or llama.cpp.

It identifies itself as AXIOM, built by Leslie Moody, focuses on coding (writing, explaining, debugging, refactoring), and is tuned to be honest and grounded.

Quick start (Ollama)

  1. Download axiom-v1.Q4_K_M.gguf and Modelfile from this repo into the same folder.
  2. Create and run the model:
ollama create axiom:v1 -f Modelfile
ollama run axiom:v1 "Write a Python function that reverses a linked list, with a docstring."

The included Modelfile carries AXIOM's system prompt (identity + coding focus + honesty) and sensible parameters (temperature 0.25, num_ctx 8192).

llama.cpp

llama-cli -m axiom-v1.Q4_K_M.gguf -p "Refactor this function for readability: ..."

Training

  • Base: 01-ai/Yi-Coder-9B-Chat (Apache 2.0)
  • Method: QLoRA (4-bit), rank 16, 1 epoch
  • Data (6,964 examples): ~1,964 docstring↔code pairs extracted from Leslie's own Python projects + 5,000 rows of iamtarun/python_code_instructions_18k_alpaca
  • Export: merged to fp16 → converted to GGUF → quantized to Q4_K_M (llama.cpp)
  • Trained on a single free-tier GPU.

Intended use

A personal / local coding assistant you fully own and run offline. Great for code help, explanations, and quick refactors.

Limitations (read this)

  • It's a 9B fine-tune, not a frontier model. It won't match large hosted assistants on hard, long-context, or agentic coding tasks.
  • English + code focused. Non-English ability is limited (the base model isn't broadly multilingual).
  • Like all LLMs it can be confident and wrong — verify generated code, and never rely on it for safety- or security-critical decisions without review.
  • A small model fine-tuned for 1 epoch can occasionally over-fit phrasing; treat its output as a strong draft, not ground truth.
