Vellium Adds Desktop Pets and CLI-Inspired Agents for Local LLMs

Vellium, an open-source crossplatform app for using local LLMs (mostly writing and RP), has shipped two major features: desktop pets and an agents tab. The project is available on GitHub at tg-prplx/vellium.

Desktop Pets

You can now create a custom pet or use a ready-made one from the Codex OAI app. The pet sits on top of all windows, changes emotions, and is interactive — hover over it to open an interface. Chat with the pet directly. The feature is described as raw, with plans to improve the everyday experience to feel more like a real desktop companion.

Agents Tab

The agents tab is disabled by default — enable it in settings. It's designed as a visual wrapper around CLI-like agents. Capabilities include:

• Reading your documents
• Running terminal commands
• Acting as a coding assistant
• Reading folders and editing files
• Connecting MCP servers (existing MCP servers can be added to the agent)

Other Updates

• Custom fields in chat mode — you can add or remove fields.
• Multiple bug fixes and smaller improvements, largely driven by GitHub issues.

The developer notes most development time went into fixing bugs. Feedback via GitHub issues is appreciated.
