OpenAI · Multimodal · Released Mar 2025

Compare

A reasoning model from OpenAI trained with reinforcement learning to perform extended chain-of-thought processing on complex problems, with a 200k token context window.

Strengths
Handles intricate multi-step reasoning tasks and produces detailed working through problems before arriving at answers.
Best for
Batch processing of complex reasoning workloads where latency is not a constraint and deeper problem-solving capability justifies longer inference times.
Limitations
Slower than standard models due to extended reasoning overhead; the batch-only variant is not suitable for real-time or interactive applications requiring immediate responses.
