One endpoint. Every model. The smart path, every request.
TYO Prism routes each request to the best, cheapest model — on your own API keys. Cut your LLM bill without cutting quality.
Bring your own keys
Register your DeepSeek, Claude, OpenAI, Qwen, Gemini, Kimi, GLM or self-hosted Ollama keys. Tokens bill to your own provider accounts — we never resell them, and your key is encrypted the moment it's saved.
Smart routing
Set model: "auto" and easy requests go to your cheap tier,
hard ones to your strong tier — decided per request, before forwarding,
with streaming preserved. Or name an upstream directly for an explicit
pick.
See the savings
Every request is metered against what it would have cost on your most expensive tier-3 upstream. The dashboard shows your savings as monthly totals and a daily chart, so you can see exactly what Prism saved you over time.
