Ways to use Crimson-Constellation-12B in osFoundry
Connect with your own key (BYOK)
Open the key dialog and paste your Vortex5 API key. osFoundry discovers Crimson-Constellation-12B 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
Crimson-Constellation-12B 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.
What hardware can run Crimson-Constellation-12B
Crimson-Constellation-12B runs on a single 16GB consumer GPU (~8 GB VRAM with KV-cache headroom). Full-precision inference fits on a single H100 80GB at FP16 precision (~29 GB).

Can I use Crimson-Constellation-12B commercially?
Commercial use is allowed with conditions. Licence terms not specified — verify the upstream model card before commercial use. Check upstream documentation.
How much VRAM does Crimson-Constellation-12B need?
Approximately 8 GB at Q4 quantisation, or 29 GB at full FP16 precision. Fits on a single 24GB consumer GPU.
Can I run Crimson-Constellation-12B locally?
Yes. Crimson-Constellation-12B is open-weights and runs locally on a workstation GPU. osFoundry's local runtime handles model loading, quantisation, and routing.
What is Crimson-Constellation-12B best at?
Crimson-Constellation-12B is well-suited to text generation.
How do I use Crimson-Constellation-12B in osFoundry?
Paste your Vortex5 API key in the key dialog (or deploy the open weights for self-hostable models), assign Crimson-Constellation-12B to a Maestro role in the Pipeline tab, then use it in chat, Room Apps via invokeAI, or your own apps.
