GPT-5.4 Mini (batch)

A lightweight variant of GPT-5.4 optimized for batch processing, with a 400k token context window.

Strengths

Balances inference speed and capability across general-purpose tasks while maintaining the larger context window of the GPT-5.4 series.

Best for

High-volume batch workloads where latency is less critical than throughput, and context length beyond 128k tokens is needed.

Limitations

Smaller and less capable than the full GPT-5.4 or GPT-5.4 Pro models; not suitable for real-time inference or tasks requiring maximum reasoning depth.
