Claude Haiku 4.5 launch
We released our fastest, most cost-efficient model – Claude Haiku 4.5. Our latest small model matches Sonnet 4’s performance on coding, computer use, and agent tasks.
Claude in Chrome updates
- Powered by Haiku 4.5: Claude in Chrome now defaults to Haiku 4.5 so it’s a faster, more responsive experience. You can always switch back to Sonnet 4.5.
- Claude handles image uploads for you: Give Claude an image and tell it where to upload, whether it’s an expense report, form attachment, or a picture upload.
- Show Claude exactly what you mean: Take a screenshot or drag to highlight specific parts of your screen. Point Claude to the exact button, field, or detail—much faster than describing complex layouts in words.
