- Added support for GPT-4.1 models (GPT-4.1, GPT-4.1-mini, GPT-4.1-nano)
- GPT-4.1 is much better at following instructions than existing models such as Claude 3.7 Sonnet and Gemini 2.5 Pro
- GPT-4.1 is good at giving diff format output, producing only changed lines
- GPT-4.1 is also much faster and cheaper than existing models
- We might switch the default model from Claude 3.5 Sonnet to GPT-4.1 in the near future, pending more testing
