GPT Engineer

GPT Engineer

GPT Engineer turns a plain-English project description into a working codebase. It prompts you for clarifications, generates all necessary files, and can iteratively improve the code through a feedback loop — all from the command line.

Key Features

• Full-project generation — produces complete, runnable codebases (not just snippets) from a single spec file
• Clarification loop — asks targeted questions before generating to reduce ambiguity
• Improve mode — run it on an existing repo to add features or fix bugs
• Benchmarked — evaluated on HumanEval and SWE-bench style tasks
• Provider agnostic — supports OpenAI, Anthropic, Azure OpenAI, and local models via LM Studio / Ollama
• Lightweight — no heavy orchestration framework; pure Python with minimal dependencies
