Axiom Python 1.5B Overview

Axiom Python 1.5B is a specialized 1.5 billion parameter causal language model, fine-tuned from the Qwen/Qwen2.5-1.5B base model. Its primary focus is on generating Python code and assisting with Python programming tasks. The model was trained using LoRA (Low-Rank Adaptation) and Supervised Fine-Tuning (SFT) on a combination of the CodeAlpaca_20K and PythonCodeInstruct_18K datasets, enhancing its proficiency in Python.

Key Capabilities

  • Python Code Generation: Optimized for creating Python functions and code snippets.
  • Instruction Following: Responds effectively to Python-related coding instructions.
  • Multilingual Support: Handles code-focused tasks in both English and Turkish.
  • Efficient Performance: A compact 1.5B parameter model suitable for various deployment scenarios.

Good For

  • Generating single-line and medium-complexity Python functions.
  • Developers seeking a lightweight model for Python code assistance.
  • Applications requiring code completion or generation based on specific instructions.
  • Use cases where stable and deterministic code output is preferred (by lowering temperature).

Limitations

  • May struggle with very complex or lengthy code generation tasks due to its size.
  • Performance is limited to Python; it is not designed for other programming languages.
  • Consistency may degrade in very long contexts, as training data had a maximum length of 256 tokens.
