GPT-5.4 (batch)

GPT-5.4 (batch) is OpenAI's general-purpose frontier model optimized for batch processing, with a 1.05M token context window for handling large documents and complex reasoning tasks.

Strengths

Handles extremely long documents and complex multi-step reasoning with a 1.05M token context window, enabling analysis of full codebases, research papers, and extended conversations in a single request.

Best for

Batch workloads that benefit from asynchronous processing and can tolerate higher latency in exchange for lower effective cost, particularly for large-scale document analysis, code review, and complex reasoning tasks.

Limitations

Batch processing introduces latency and is not suitable for real-time or interactive applications; for immediate responses, use the non-batch GPT-5.4, or consider GPT-5.4 Pro (batch) if you need even more advanced reasoning capabilities.
