Optimal
Optimal is MIOSA’s built-in agent.
You describe what you want in a chat, and Optimal answers from your live workspace, builds on a machine you choose, or investigates a problem.
Open it from Optimal in the console sidebar, at /optimal.
What Optimal does
- Answers questions about your organization and workspace: what is running, what changed, how something is set up.
- Builds on a sandbox or computer: it writes files, runs commands, serves a live preview, and can publish what it built.
- Investigates a problem: it traces evidence, such as a failed deployment or an error in your logs, before it reaches a conclusion.
- Asks before it acts: steps that change your workspace wait for your approval unless you allow them.
Optimal works only inside your organization and workspace, with your permissions. See Isolation and permissions.
Brains: who does the work
Before the first message you pick the brain that answers the chat.
| Brain | Who pays | What runs |
|---|---|---|
| Optimal | Wallet credits | MIOSA’s own model, with a 1M-token context |
| A harness | Your own account | Claude Code, Codex, OSA, and the other harnesses run on a machine |
| A saved agent | Your own account | An agent you built in Agent Studio, with its own instructions and tools |
The brain is locked after the first message. To change it, start a new chat. See Brains and agents.
Ask, Build, Investigate
Every chat is in one of three modes.
| Mode | What it does |
|---|---|
| Ask | Answers from live workspace context, without touching a machine |
| Build | Builds or changes something on a sandbox or computer |
| Investigate | Traces evidence before reaching a conclusion |
Investigate always runs on the Optimal brain. See Chats and modes.
Pricing in one line
The Optimal brain costs $1.50 per 1M input tokens and $6.00 per 1M output tokens, paid from wallet credits where 1 credit is 1 cent. A typical message is about 4 credits. Machines Optimal uses are billed at their normal rate. A harness or saved agent bills its model to your own account. See Pricing and usage.
