Anthropic launches a new small model called Haiku 4.5.
The company says it codes just as well as Claude Sonnet 4 but does so “significantly faster” and at a third of the cost. Anthropic’s advanced model is the recently released Sonnet 4.5, which can “break down a complex problem into multi-step plans” and manage several Haiku 4.5s to implement the subtasks concurrently. Haiku 4.5 is now available on free Claude plans.
Update: Free Claude plans do not default to Haiku 4.5.
