GPT-5 Pro (batch)

OpenAI's advanced general-purpose reasoning model optimized for batch processing of complex tasks with step-by-step reasoning and instruction following.

Strengths

Handles complex reasoning, code quality, and instruction following across diverse workloads with a 400k token context window.

Best for

Batch processing workflows where latency tolerance allows for asynchronous execution of reasoning-heavy tasks at scale.

Limitations

Designed for batch use cases rather than real-time applications; newer general-purpose models like GPT-5.1 (batch) offer the same reasoning capabilities in a more recent release.
