    Usage and cost

    • Per-request accounting by token, model, and channel, with the billing detail visible in the log
    • Input, output, cache-hit, and reasoning tokens counted separately, including cache billing for OpenAI, Azure, DeepSeek, Claude, and Qwen
    • Per-call and per-usage billing policies, plus group ratios
    • Internal top-ups and quota allocation (Yipay, Stripe)

    Authentication and security

    • OAuth sign-in: GitHub, Discord, LinuxDO, Telegram
    • OIDC single sign-on
    • WebAuthn / Passkeys
    • Tokens can be scoped by group, model, quota, and expiry

    Smart routing

    • Weighted random channel selection
    • Automatic retry on another healthy channel after a failure
    • Per-user model rate limiting

    Formats and conversion

    Supported request formats and conversion directions are listed in the API reference. The point is that a client speaking one format can reach an upstream speaking another, without per-provider code.

    Reasoning effort

    Reasoning effort is selected with a model-name suffix, with no change to the request body:

    FamilyHow to write it
    OpenAIo3-mini-high / -medium / -low, gpt-5-high / -medium / -low
    Claudeclaude-3-7-sonnet-20250219-thinking enables thinking mode
    Geminigemini-2.5-flash-thinking / -nothinking, or append -low / -medium / -high to the model name

    Gemini also accepts an explicit budget, as in gemini-2.5-pro-thinking-128.

    Model and task types

    Chat, Responses, Realtime, images, audio, video, embeddings, and rerank, plus asynchronous task APIs such as Midjourney Proxy and Suno.
