Gemini Pro is quite good at unified diffs. Not good enough to apply literally with patch, but aider has a very flexible udiff backend. I mostly use Gemini like: aider --model gemini --edit-format udiff-simple Benchmarks a bit worse, so I'm reluctant to make it default.

Gemini 2.5 Pro Preview 05-06 scored 77% on the leaderboard, coming in 2nd place close behind o3 (high). Full leaderboard: aider.chat/docs/leaderboa…

The $6.32 benchmark cost for Gemini 2.5 Pro Preview 03-25 was incorrect. The true cost was higher, possibly significantly so. Unfortunately 03-25 is no longer available to re-run. The new 05-06 version costs $37 to run the benchmark. Root cause analysis: aider.chat/2025/05/07/gem…
