GPT-5 Pro

OpenAI's general-purpose reasoning model with a 400k token context window, released in October 2025 as part of the GPT-5 generation.

Strengths

Handles complex reasoning and multi-step problem solving across a wide range of domains with strong performance on analytical and creative tasks.

Best for

General-purpose applications that require reasoning and analysis but don't specialize in coding; for real-time API use (GPT-5 Pro batch is the asynchronous variant).

Limitations

Not optimized for coding tasks—GPT-5 Codex is purpose-built for programming; for asynchronous batch workflows, use GPT-5 Pro (batch) instead; GPT-5.1 supersedes this model as the newer reasoning release.
