Built for developers and AI apps

DUKOU AI sits between your application and upstream model providers, giving you a unified, reliable model access layer.

Unified API
An OpenAI-compatible API: keep your existing SDKs and just change the base URL and API key.
Multi-model access
Call models from OpenAI, Claude, Gemini, DeepSeek and more with a single key — no per-vendor auth or protocol work.
Reliable routing & failover
Upstream channels are selected by priority, weight, and health; on connection errors before any output, a backup channel is tried automatically.
SSE streaming
Full streaming support: model output is forwarded to your client as it is generated, with no wait for the complete response.
Usage & cost management
Token usage, cost, and latency are recorded per request; check balance, billing, and daily/per-model stats in the console anytime.
Security & privacy
Request and response content is not stored by default — only billing metadata. API keys are stored as irreversible hashes.
