Anthropic has introduced Claude Haiku 4.5, a new AI model that prioritizes speed and cost efficiency while delivering performance close to its larger sibling, Claude Sonnet. Marketed as a sub‑agent that can handle small, targeted tasks under the direction of larger models, Haiku 4.5 becomes the default option for all Claude free‑tier users. The model promises double the latency speed of previous small models, lower sycophancy, and tighter integration with Anthropic’s tool ecosystem, offering a faster, cheaper entry point for developers and everyday users alike.

Anthropic introduced Claude Haiku 4.5, a compact AI model designed to deliver high intelligence and speed at a fraction of the cost of its larger counterparts. Priced at $1 per million input tokens and $5 per million output tokens for API users, Haiku 4.5 undercuts Sonnet 4.5 and Opus 4.1 while matching frontier‑level performance on benchmarks such as SWE‑bench. The model targets real‑time, low‑latency tasks like chat assistants, customer service, and pair programming, and can be combined with Sonnet 4.5 in multi‑model workflows. Documentation and system cards are now available for developers. Leer más →
