- Claude Haiku 4.5 is the latest small model available to all users, offering similar coding performance to Claude Sonnet 4 but at one-third the cost and more than twice the speed.
- It surpasses Claude Sonnet 4 in certain tasks like computer use, making applications like Claude for Chrome faster and more useful.
- Ideal for real-time, low-latency tasks such as chat assistants, customer service agents, or pair programming due to its high intelligence and speed.
- Claude Haiku 4.5 is priced at $1/$5 per million input and output tokens, making it a cost-efficient option for near-frontier performance.
- In benchmarks, it achieves 90% of Sonnet 4.5's performance in agentic coding evaluations, matching much larger models.
- The model is particularly strong in sub-agent orchestration and computer use tasks, making AI-assisted development feel instantaneous.
- Claude Haiku 4.5 is our safest model yet, with low rates of concerning behaviors and alignment issues, classified under AI Safety Level 2 (ASL-2).
- Available on Claude Code, our apps, API, Amazon Bedrock, and Google Cloud’s Vertex AI as a drop-in replacement for Haiku 3.5 and Sonnet 4.
- Detailed technical and safety evaluations are available in the system card, model page, and documentation.
