Claude Haiku 4.5 (latest)

Claude Haiku 4.5 continues Anthropic's Haiku line as the lightweight, latency-focused member of the Claude family, positioned for interactive and high-volume workloads where quick turnaround matters more than maximum depth. Independent cataloging confirms its Anthropic-side identifier (claude-haiku-4-5-20251001), aligning with the page's key, and it sits within Anthropic's broader lineup alongside heavier Claude variants, giving teams a natural tiered option from faster Haiku through mid-range Sonnet to top-tier Opus.

Beyond its speed-first positioning, the model brings genuinely broad capability: multimodal input handling for text, image, and PDF documents combined with text generation, plus reasoning, tool calling, temperature control, and structured output support make it suitable for classification, customer-facing chat assistants, document Q&A, lightweight coding helpers, and routing or preprocessing tasks in agent pipelines. Its large context window and generous max output accommodate multi-document reasoning and longer responses, while the low per-token pricing makes sustained, high-volume use economically viable.
