o4 mini

o4-mini is tuned for responsiveness while keeping steady accuracy on analysis, math, and software tasks. It follows instructions cleanly, stays coherent across multi-document prompts, and returns structured results that downstream systems can parse without brittle post-processing. The model integrates with retrieval to ground answers in your data, supports function calls for searches and actions, and keeps latency predictable for high-traffic apps. Most teams use o4-mini as the default engine for chat, support, workflow automation, and repo-aware code help.
