Anthropic has launched Claude Haiku 4.5, its latest small AI model, now available to all users, offering near-frontier performance with exceptional speed and cost-efficiency. Positioned as a faster and more affordable alternative to larger models, Claude Haiku 4.5 delivers coding performance comparable to Claude Sonnet 4-a state-of-the-art model released five months ago-at one-third the cost and more than twice the speed. It even surpasses Sonnet 4 in select areas, such as computer interaction, enhancing applications like Claude for Chrome with greater responsiveness.

Designed for real-time and low-latency use cases, Haiku 4.5 is ideal for chat assistants, customer service agents, and pair programming. Developers using Claude Code can expect smoother, faster workflows across multiple-agent projects and rapid prototyping. While Claude Sonnet 4.5 remains Anthropic’s frontier model and the top coding model globally, Haiku 4.5 provides a cost-effective option that complements it-allowing Sonnet 4.5 to delegate complex tasks to multiple Haiku 4.5s working in parallel. Claude Haiku 4.5 is available globally through the Claude API at a price of $1/$5 per million input and output tokens, reinforcing Anthropic’s commitment to scalable, high-performance AI solutions.
