GPT-6 Astra Pro (batch)

OpenAI's flagship model in the GPT-6 series, optimized for asynchronous batch processing with a 1.05M token context window.

Strengths

Handles complex end-to-end work at scale when processing time is not a constraint, with the reasoning capability and broad knowledge of OpenAI's top-tier Astra model line.

Best for

Batch workloads requiring the highest capability—comprehensive document analysis, multi-step research, complex reasoning tasks, or large-scale processing where latency tolerance allows asynchronous operation.

Limitations

Batch-only availability means it cannot serve real-time or interactive applications; for lower-latency use cases or faster inference, non-batch variants or faster models like Luna are required.
