CodeLlama 70B Python

CodeLlama 70B Python is Meta's highest-capacity Python-specialized code model, released as part of the CodeLlama 70B family in early 2024. It has 70 billion parameters and is produced by fine-tuning CodeLlama 70B on Python-specific training data, maximizing Python code generation accuracy. The context window is 16,384 tokens. Like other Python-specific CodeLlama variants, it is optimized for completion and fill-in-the-middle (FIM) infilling rather than instruction following—it operates on code completion prompts and FIM tokens rather than conversational prompts.

At 70 billion parameters, this model represents the highest CodeLlama scale for Python tasks. It outperforms the 7B and 13B Python variants on complex Python generation tasks: larger algorithm implementations, accurate inference of library APIs, and multi-function code blocks. The large parameter count enables better pattern recognition across diverse Python codebases and library usage styles. Serving in FP16 requires approximately 140GB VRAM, typically requiring 2–4 high-memory GPUs.

CodeLlama 70B Python is available as open weights on Hugging Face (meta-llama/CodeLlama-70b-Python-hf) under Meta's Code Llama Community License, and is hosted on Together AI, Fireworks AI, Azure AI Foundry, and Replicate. For instruction-following use with Python code generation, the CodeLlama 70B Instruct variant is more appropriate. For new Python-specialized deployments, Qwen2.5-Coder or Qwen3-Coder models offer better benchmark results with longer context windows.
