A compact reasoning model in OpenAI’s o-series, optimized for fast, cost-efficient performance while retaining strong multimodal and agentic capabilities. Supports tool use and demonstrates competitive reasoning and coding performance across benchmarks, outperforming its predecessor o3-mini and approaching o3 in some domains. Well-suited for high-throughput scenarios where latency or cost is critical.

No. O4 Mini was retired on NagaAI on Oct 23, 2026, and requests to it now return an error. Live models you can use instead with the same API key: GPT-6.1 Terra, GPT-6.1 Sol and GPT-6 Luna.
It takes text, images and files as input and returns text.
