Another amazing Claude model just came out — blazing fast
Anthropic just released another incredible coding model — and the speed is unbelievable.
The new Claude Haiku 4.5 gives you all the intelligence of Sonnet 4.5 at only a fraction of the cost.

It’s leaner, it’s faster, it’s cheaper — and it even comes with a brand new feature never seen before in this line of models.
Haiku 4.5 is built for pure speed. Speed is what this is all about.

This model is perfect for anything needing a real-time response — chat assistants, customer service bots, or coding copilots.
IDEs like Cursor have already added support for it — to make your development even smoother with quicker responses.

Being significantly faster than Sonnet 4.5 definitely makes for a much snappier user experience. Near-premium performance for much less.
This is a model that can be deployed at massive scale — making powerful AI more accessible for anyone looking to manage costs — even powering free-tier user experiences.
And the new Extended Thinking ability makes it even better.
With Extended Thinking you can boost complex reasoning and get even better accuracy with your coding — thinking harder to handle multi-step problems that would have previously required a slower, larger model like Sonnet.
Haiku 4.5 even supports Computer Use — which means it can autonomously use your PC to carry out complex tasks.

Manage files, fill out forms, handle spreadsheets and email… the possibilities are endless.
Haiku 4.5 processes both text and images and supports large context windows — up to ~200k tokens with generous output — making it suitable for manage full codebases and image-assisted tasks.
It also scores very well in industry benchmarks like SWE-bench.

Its speed also makes it ideal for multi-agent systems, where a larger model like Sonnet 4.5 could handle the overall plan, and multiple Haiku agents execute the parallel subtasks — like code refactoring or document analysis.
Claude Haiku 4.5 is a major step forward in making high-performance AI more affordable and deployable.
It’s not just a smaller sibling to Sonnet — it’s a purpose-built engine for real-time intelligence.
With new features like Extended Thinking and Computer Use it bridges the gap between speed and sophistication — giving you high-power state-of-the-art intelligence at scale.
