How It Works

Four steps. Zero configuration.

Drop in your API keys. Use the same OpenAI-compatible endpoint you already know.

Step 01
🔑

Register your keys

Bring your own Anthropic, OpenAI, and DeepSeek keys. Encrypted with AES-256-GCM at rest. We never see them.

Step 02
🧠

Intent classifier runs

Every prompt is scored across 8 intent categories: code, math, summary, research, creative, structured, vision, and chat.

Step 03

Optimal model selected

Models are scored by capability match, cost, latency, and provider health. Circuit breakers handle failures automatically.

Step 04
🔄

Fallback chains protect you

If the primary model fails or is rate-limited, we cascade through your fallback chain silently. Zero downtime.

Model Registry

Right model. Right task.

Each model is rated for its ideal intents. The router always picks the most cost-efficient match.

Pricing

Start free. Scale when ready.

Your API keys, your spend. We charge for routing — not tokens.
