This entry points to the same project as Aider Chat elsewhere in this directory: an open-source AI pair programmer that runs in the terminal, maps a codebase for context, and auto-commits its own changes to git with sensible messages. It connects to GPT-4o, Claude, DeepSeek, Gemini, and other models rather than being tied to one provider.
Development is active and maintained by Paul Gauthier, with frequent updates to model support, including newer reasoning models, expanded language compatibility covering things like MATLAB and Clojure, and ongoing performance tuning. On its own polyglot benchmark of 225 coding tasks across multiple languages, it has reported correctness scores in the mid-80% range using strong frontier models, a result the project highlights as evidence of real competitiveness with much larger commercial coding agents.
Since this is a duplicate listing of the same underlying tool, it's worth consolidating with Aider Chat rather than treating them as two separate products when comparing options.
