Anthropic Release Notes

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.

• We've launched Claude Sonnet 4.5, our best model for complex agents and coding, with the highest intelligence across most tasks. Learn more in the models overview.
• We've introduced global endpoint pricing for Amazon Bedrock and Vertex AI. The Claude API (1P) pricing is unaffected.
• We've introduced a new stop reason model_context_window_exceeded that allows you to request the maximum possible tokens without calculating input size. Learn more in Handling stop reasons.
• We've launched the memory tool in beta, enabling Claude to store and consult information across conversations. Learn more in Memory tool.
• We've launched context editing in beta, providing strategies to automatically manage conversation context. The initial release supports clearing older tool results and calls when approaching token limits. Learn more in Context editing.
