Integration of GPT-4.1 model into Modes

I suggest adding the option to select the GPT-4.1 model in Modes. This new model, released by OpenAI on April 15, 2025, offers significant improvements compared to GPT-4o at a lower cost.

Key advantages:

1. Cost is 26% lower compared to GPT-4o with higher performance;

2. Improved instruction understanding (38.3% result in Scale's MultiChallenge, which is 10.5% higher than GPT-4o);

3. Enhanced caching — increased discount up to 75% (previously 50%).
