Joined September 2020
We just launched Claude Sonnet 4.5 and “Imagine with Claude”, a 5-day preview that creates dynamic experiences for you in real-time (and the first product I’ve worked on at Anthropic!). It pioneers the concept of “model-as-backend”, using a model to not only generate interfaces

We just launched Haiku 4.5, which gives Sonnet 4 performance at twice the speed and a third the cost.
Introducing Claude Haiku 4.5: our latest small model. Five months ago, Claude Sonnet 4 was state-of-the-art. Today, Haiku 4.5 matches its coding performance at one-third the cost and more than twice the speed.

Demo extended for one more week. Pro and Max users can keep imagining with Claude.
We're also releasing a temporary research preview called "Imagine with Claude". In this experiment, Claude generates software on the fly. No functionality is predetermined; no code is prewritten. Available to Max users for 5 days. Try it out:

For the prompt, I asked Claude to generate an interactive “choose your own adventure” game based on my startup experience. It accurately retold our pivot from VR games to management, even making an interactive management dashboard and app launcher to showcase key functionality:

We built a system that detects highly complex objects NO vision model can find—introducing tool use for vision. 🧵 Say you wanted to detect for the @ycombinator logo in this image. (▶️ see step-by-step thinking) Using our solution, it's able to detect the logo perfectly,
