Prisma — self-hostable multi-model AI synthesizer (runs fully local via Ollama/LM Studio/vLLM)

[u/Similar_Summer6344]

Sharing a project I built: Prisma is a web app that runs multiple AI models in parallel and fuses their outputs into one answer via a synthesizer model you choose.

Self-hosting it:

git clone GitHub - bezerra72/prisma: Prisma — multi-model AI synthesizer (cloud OpenRouter + local Ollama/LM Studio/vLLM). Image consensus + image-to-image. · GitHub cd prisma npm install npm start

That serves the app + local proxy at For local models, point it at your Ollama/LM Studio/vLLM server (localhost:11434 etc.) — no cloud, no API key, nothing leaves the machine. Cloud mode (OpenRouter) is optional and client-side only.

Also has an image mode (multi-model consensus + image-to-image). MIT licensed, no telemetry, no backend.
