GPT-5.4 Nano (batch)

GPT-5.4 Nano is OpenAI's lightweight variant from the GPT-5.4 series, optimized for batch processing with a 400k token context window.

Strengths

Delivers fast inference and efficient resource usage while maintaining reasoning and general-purpose capabilities across a wide range of tasks.

Best for

High-volume batch processing jobs where speed and efficiency matter more than the reasoning depth of GPT-5.4 Pro or the extended context of the frontier models.

Limitations

Smaller and less capable than GPT-5.4 and GPT-5.4 Pro, and lacks the multimodal or specialized coding features of other variants in the lineup.
