Ways to use Pluto in osFoundry
Connect with your own key (BYOK)
Open the key dialog and paste your MerlinSafety API key. osFoundry discovers Pluto automatically — assign it to a Maestro role (router, direct, orchestrator, or fallback) in the Pipeline tab and it is live in every chat. Your key, your provider account — no token markup.
Deploy a dedicated endpoint
Pluto is open-weights — run it locally for free, or deploy a dedicated GPU endpoint in your workspace for reserved capacity with no rate limits.
Use it in a Room App
Room Apps declare AI features in their manifest, then call them with invokeAI:
import { invokeAI } from '@osfoundry/app-sdk'
// 'summarize' is an AI feature declared in your app manifest.
const result = await invokeAI('summarize', userText)
Call it from your own apps
Once a model is wired into your workspace you can host it as an API and reach it from your own services, scripts, or CI — outside osFoundry.

Commercial use is allowed with conditions. Licence terms not specified — verify the upstream model card before commercial use. Check upstream documentation.
Can I run Pluto locally?
Yes. Pluto is open-weights and runs locally on a workstation GPU. osFoundry's local runtime handles model loading, quantisation, and routing.
What is Pluto best at?
Pluto is well-suited to image text to text.
How do I use Pluto in osFoundry?
Paste your MerlinSafety API key in the key dialog (or deploy the open weights for self-hostable models), assign Pluto to a Maestro role in the Pipeline tab, then use it in chat, Room Apps via invokeAI, or your own apps.
