Ways to use Qwen2.5-1.5B-Instruct-Math-Reasoning-GRPO-Tuned in osFoundry
Connect with your own key (BYOK)
Open the key dialog and paste your Fardan API key. osFoundry discovers Qwen2.5-1.5B-Instruct-Math-Reasoning-GRPO-Tuned 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
Qwen2.5-1.5B-Instruct-Math-Reasoning-GRPO-Tuned 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 Qwen2.5-1.5B-Instruct-Math-Reasoning-GRPO-Tuned
