## Summary

OpenAI has launched GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano in its API, which it says outperform GPT-4o and GPT-4o mini across the board, with major gains in coding and instruction following. The models support up to 1 million tokens of context, up from 128,000 for previous GPT-4o models, and have a June 2024 knowledge cutoff. GPT-4.1 scores 54.6% on SWE-bench Verified, compared to 33.2% for GPT-4o, and 38.3% on Scale's MultiChallenge instruction-following benchmark. OpenAI also plans to turn off GPT-4.5 Preview in the API on July 14, 2025.
