GPT-5.4 Pro (batch)

OpenAI's most advanced general-purpose model from the GPT-5.4 series, optimized for batch processing with a 1.05M token context window.

Strengths

Handles complex reasoning, long-document analysis, and nuanced tasks at the frontier of the GPT-5.4 lineup with maximum context capacity.

Best for

Batch processing of large documents, complex multi-step reasoning, and workloads where the highest model capability matters more than latency.

Limitations

Batch-only operation makes it unsuitable for real-time or interactive use cases; for synchronous applications, use the standard GPT-5.4 Pro variant instead.
