I just finished updating the aider polyglot leaderboard [0] with GPT-4.1, mini and nano. My results basically agree with OpenAI's published numbers.

Results, with other models for comparison:

    Model                       Score   Cost

    Gemini 2.5 Pro Preview 03-25 72.9%  $ 6.32
    claude-3-7-sonnet-20250219   64.9%  $36.83
    o3-mini (high)               60.4%  $18.16
    Grok 3 Beta                  53.3%  $11.03

Aider v0.82.0 is also out with support for these new models [1]. Aider wrote 92% of the code in this release, a tie with v0.78.0 from 3 weeks ago.
