Claude Opus 4.6 (batch)

Claude Opus 4.6 in batch mode — Anthropic's flagship reasoning model optimized for asynchronous processing with a 1 million token context window.

Strengths

Handles complex reasoning and long-horizon tasks across large documents or codebases, with the full depth of Opus-tier capability in batch mode.

Best for

Non-real-time workflows that require strong reasoning over very long contexts, such as batch document analysis, large-scale code review, or offline research synthesis.

Limitations

Batch mode introduces latency compared to synchronous APIs; it is not suitable for interactive applications or real-time decision-making, and has been superseded by Claude Opus 4.8 (batch) for reasoning performance.
