GPT-4.1 Nano (batch)

OpenAI's smallest and fastest text model, designed for low-latency classification and routing with a 1 million token context window.

Strengths

Delivers fast inference and handles long documents efficiently due to its compact size and extended context window.

Best for

Batch processing of high-volume classification, routing, and extraction tasks on long texts.

Limitations

As the smallest model in the GPT-4.1 series, it trades reasoning depth and nuance for speed and throughput, making it less suitable for complex analytical or creative tasks.
