The fastest and most cost-effective model in the GPT-4.1 series, designed for tasks demanding low latency such as classification and autocompletion. Maintains a 1 million token context window and delivers exceptional performance at a small size, outperforming even some larger models on key benchmarks.
Retired on Oct 23, 2026: requests to this model ID now return an error. These models are live and work with the same API key.
