- R · What Makes It Special
- Anthropic's Claude Haiku 4.5 (October 15, 2025), a small model with coding performance similar to the earlier frontier model Claude Sonnet 4 at one-third the cost and more than twice the speed, and better computer use; built for real-time, low-latency work such as chat assistants, customer service agents, pair programming and sub-agents orchestrated by Sonnet 4.5, it costs $1/$5 per million tokens (API ID claude-haiku-4-5-20251001) and has since been followed by Claude Haiku 5.5.
