Claude Opus 4.1 (batch)

Claude Opus 4.1 in batch mode is Anthropic's previous-generation flagship model for asynchronous, non-real-time processing with a 200k-token context window.

Strengths

Strong on coding, reasoning, and agentic tasks, with demonstrated performance on complex software engineering benchmarks.

Best for

Batch processing workflows that prioritize reasoning depth and autonomy over latency, particularly for code generation and multi-step agentic operations.

Limitations

Superseded by Claude Opus 4.5 (batch) in November 2025, which added the 1M context window and incorporated the 67% Opus price reduction; Claude Opus 4.1 batch uses the earlier 200k context and legacy pricing tier.
