Claude, we're really excited about the release of Haiku 4.5! As Anthropic's newest model, its speed and performance improvements will bring a smoother experience to GitHub Copilot users.

Which one to choose? Sonnet 4.5 or Haiku 4.5 For the most advanced, complex, and longest coding projects: Use Sonnet 4.5.  For faster, more straightforward tasks, or when cost and speed are priorities: Use Haiku 4.5. (see Haiku at 0.33x vs Sonnet is at 1x premium rate) For maximum efficiency on large projects: Use them together. Sonnet 4.5 can create the overall plan, and Haiku 4.5 can execute smaller, repetitive tasks in parallel.

Perfect. Time to see how close Haiku 4.5 gets to the full Sonnet/Opus feel. Any reviews, experiences? 🚀

Time to test Haiku for Vibe coding. 😎

Exciting news about Claude Haiku 4.5! Looking forward to seeing its impact on GitHub Copilot. GitHub

Claude Haiku for the first time letss goo.

Claude, we're so excited about the release of Haiku 4.5! Its use in GitHub Copilot will significantly improve developer productivity. The increased performance and speed mean we can complete projects faster and spend less time developing.

Just built a rather complex app with Sonnet 4.5. It is amazing!

Exciting update. Faster reasoning inside Copilot means smoother workflows and more natural code completion.
