Latency & Speed
o3 MiniFaster
Speed score0/100
o3 Mini High
Speed score0/100

Both models have comparable response speeds. For most applications, the latency difference is negligible.

When latency matters most: Interactive chatbots, IDE code completion, real-time translation, and user-facing applications where response time directly impacts experience. For batch processing, background summarization, or offline analysis, latency is less critical.

Example Use Cases

Code generation & review

Based on overall model capabilities and architecture for coding tasks like generating functions, debugging, and refactoring

o3 Mini

Customer support chatbot

Suitable for user-facing chat with competitive response times. o3 Mini also offers lower per-token costs for high-volume support

o3 Mini
