AgentsRoom Adaptive Mode: Haiku for the typo, Opus for the architecture, same agent, no restart
A real session, filmed in the app: Adaptive Model is turned on under Settings > Composer with Every message and Automatic. A new Claude Code agent starts on Opus, a request to fix one typo in the README switches it to Haiku before the message leaves, with no restart and nothing typed in the terminal, and the chip confirms Haiku answered. An architecture question in the same conversation sends it straight back to Opus.

Haiku for the typo, Opus for the architecture. Same agent, no restart. This is AgentsRoom, the desktop app where your AI coding agents work side by side.
Adaptive Mode picks a model for each message. In Settings, under Composer, turn Adaptive Model on. Nothing to install: no plugin, no proxy, no key.
It is off by default, because the first 500 characters of a message go to AgentsRoom's servers to choose. Turn on Every message, then choose Automatic. For now, Automatic works with Claude Code and Codex.
Now I add a new Claude Code agent. It starts on Opus, the most expensive model. I ask it to fix one typo in the README.
Before the message leaves, it switches to Haiku. The model in its header follows. No restart, nothing typed in the terminal.
The typo is fixed. Hover the chip: the API itself confirms that Haiku answered. Then an architecture question, in the same conversation.
It goes straight back to Opus. Opus compares two storage designs. And you rate each choice with the thumbs.
A small model for small tasks, the big one when it counts. Adaptive Mode is in AgentsRoom, per project or from your phone. The link is in the description.
