Claude Haiku 4.5 (batch)

Claude Haiku 4.5 in batch mode is Anthropic's fastest and most cost-effective model, optimized for asynchronous processing with a 200k-token context window.

Strengths

Haiku excels at speed and efficiency, handling simple to moderately complex tasks with minimal latency and low token consumption.

Best for

Batch workloads where throughput matters more than reasoning depth, such as content classification, summarization, and straightforward data processing.

Limitations

Lacks the reasoning capability and context window of larger models; Sonnet and Opus variants are better suited for complex problem-solving or tasks requiring extended context.
