salesforce/CodeGen
CodeGen is a family of open-source model for program synthesis. Trained on TPU-v4. Competitive with OpenAI Codex.
CodeGen2 introduces infill sampling capabilities for bidirectional code completion, while CodeGen2.5 achieves superior performance with reduced model size through improved training techniques. Models integrate seamlessly with Hugging Face Transformers via standard `AutoModelForCausalLM` interface, trained using the Jaxformer library built on JAX for efficient multi-turn program synthesis across Python, Java, and JavaScript.
