Get ready for a game-changer! We're thrilled to introduce Claude Haiku 4.5, our latest small model that's set to revolutionize the AI landscape. This model is not just a minor upgrade; it's a significant leap forward in terms of performance and accessibility. Imagine having access to cutting-edge coding capabilities at a fraction of the cost and with lightning-fast speed - that's the power of Claude Haiku 4.5!
What's even more impressive is that this model surpasses its predecessor, Claude Sonnet 4, in certain tasks, especially when it comes to utilizing computers. This means that applications like Claude for Chrome will now be faster and more efficient than ever before.
For those relying on AI for real-time tasks, such as chat assistants or customer service agents, Haiku 4.5 offers the perfect blend of intelligence and speed. And if you're a developer working on coding projects, you'll find that Haiku 4.5 enhances your workflow, making it more responsive and efficient.
While Claude Sonnet 4.5 remains our flagship model, Claude Haiku 4.5 provides an excellent alternative for those seeking cost-effective, high-performance AI. It opens up new possibilities for combining models, allowing for complex problem-solving with multiple agents working in parallel.
But here's where it gets really exciting: Claude Haiku 4.5 achieves an incredible balance between coding quality, speed, and cost efficiency. In independent evaluations, it scored an impressive 90% of Sonnet 4.5's performance, outperforming much larger models. This model truly blurs the lines between quality and cost, offering a glimpse into the future of AI development.
And this is the part most people miss: speed is the new frontier for AI agents. Haiku 4.5 proves that you don't have to sacrifice intelligence for rapid output. It handles complex tasks with ease, self-corrects in real-time, and maintains a smooth workflow without any latency issues.
In our tests, Haiku 4.5 excelled in instruction-following and slide text generation, achieving accuracy levels that are a game-changer for developers. It even brings efficient code generation to GitHub Copilot, offering a faster and more responsive experience.
But what about safety? We've conducted extensive safety evaluations, and the results are promising. Claude Haiku 4.5 demonstrates low rates of concerning behaviors and is significantly more aligned than previous models. In fact, it's our safest model yet, according to our automated alignment assessment.
We've released Claude Haiku 4.5 under the AI Safety Level 2 (ASL-2) standard, which means it poses limited risks in terms of CBRN weapons production. You can find more details about our safety tests and the model's classification in our system card.
Claude Haiku 4.5 is available now on Claude Code and our apps. Developers can access it via our API, Amazon Bedrock, or Google Cloud's Vertex AI. With its efficiency, you can accomplish more while maintaining top-notch performance.
