GPT-4.1 is strong at code and gives developers a context window of 1 million tokens.
On April 14, 2025, OpenAI launched GPT-4.1 in the API — the first production model with a context window of 1 million tokens for developers.
For developers
GPT-4.1 (with mini and nano variants) excelled at coding and instruction-following, at lower cost than previous models.
Long context as standard
The enormous context window made it suitable for entire codebases and long documents in a single call.
