GPT-5 (batch)

OpenAI's general-purpose model with a 400k token context window, optimized for batch processing where latency is not a constraint.

Strengths

Handles long-context reasoning and document processing efficiently through batch mode, with the full reasoning capabilities of the GPT-5 family.

Best for

Batch jobs requiring extended context windows, such as processing large documents, generating summaries across long texts, or running non-time-sensitive inference at scale.

Limitations

Batch-only availability means it is not suitable for real-time or interactive applications; for immediate responses, GPT-5 Chat or the standard GPT-5 are better choices.
