Claude Sonnet 4.5 and Built-in Python Plugin 🐍

From September through October, LobeHub added a built-in Python execution environment, integrated Claude Sonnet 4.5, and improved how you navigate and edit content in long conversations.

Run Python code directly in chat

The new built-in Python plugin lets you execute Python code without leaving the conversation. Run calculations, transform data, or test snippets and see results immediately alongside your discussion.

This keeps your workflow in one place—no need to switch to a separate notebook or terminal when you need to verify something quickly.

The new chat list minimap gives you a condensed view of long conversations, making it easier to jump to specific sections without endless scrolling.

Richer editing and content handling

The rich text editor now supports math formulas, task lists, and parallel sending. This makes it easier to draft structured messages with mixed content types.

Qwen image editing is also available—edit images through Qwen models directly in the chat interface.

Model and provider updates

Claude Sonnet 4.5 brings Anthropic's latest reasoning capabilities to LobeHub. The release also adds Vercel AI Gateway as a provider, alongside Seedream 4.0, CometAPI, and NewAPI. Gemini 2.5 video understanding capabilities are updated.

Improvements and fixes

  • Chat input is now resizable for comfortable drafting
  • Mobile title display is improved
  • Base64 image syntax is now supported
  • .doc file parsing is more reliable
