Built on OpenRouter.ai

One switch.
Every model, one conversation.

Arvethon puts every major AI model behind a single dial. Turn it mid-chat without losing your thread — one interface, no juggling five tabs.

Now on the dial
Any model on OpenRouter

Add or swap models without touching the frontend — Arvethon reads the live OpenRouter catalog.

How it works

Three moves, not three tabs

The dial is the whole idea: pick a model, talk, switch, keep going.

01

Sign in once

A single account gets you into the chat and, if you build on Arvethon, the developer console too.

02

Turn the dial

Pick a model from the switcher before you type, or mid-conversation — your history carries over.

03

Keep the thread

Every reply is saved to that conversation, so switching models never means starting over.

Whatever's on OpenRouter

The model list isn't hardcoded — it's pulled live, so it grows as OpenRouter adds new ones.

GPT family Claude family Gemini family Llama family Mistral family Qwen family DeepSeek family + new arrivals

Every model follows the same house instructions, so tone stays consistent no matter which one answers.

For developers

Build on the same dial

Generate an API key, read the docs, and call Arvethon the same way the chat app does.

Go to developer console
POST /api/chat
{
  "model": "anthropic/claude",
  "message": "..."
