OpenAI Gpt 4.1, GPT‑4.1 mini, and GPT‑4.1 nano

GPT-4.1 (and -mini and -nano) are now available in the API!

these models are great at coding, instruction following, and long context (1 million tokens).

benchmarks are strong, but we focused on real-world utility, and developers seem very happy.

GPT-4.1 family is API-only.
