Hey everyone!
Claude just released Haiku 4.5. А small model that pushes the boundaries of speed and efficiency.
What stood at the frontier only five months ago (Claude Sonnet 4) is now available at one-third the cost and more than twice the speed, while even surpassing it on tasks like computer use.
For real-time applications: chat assistants, customer support, or pair programming, Haiku 4.5 delivers near-frontier intelligence with remarkable responsiveness. And for coding, it makes multi-agent projects and rapid prototyping feel smoother than ever.
