LLM API Gateway
One key for chat models and System One.
Public English name: LLM API Gateway / Unified AI API. Chinese: AI+U / aijiau 模型 API, or 大模型 API 网关. High cost-performance, OpenAI-compatible, one key for many models, for people who build agents. Jev System One uses the same key on a different door. Keys and billing stay at api.aijiau.com — www is not a second console.
OpenAI-compatible
Chat models use POST /v1/chat/completions. Point an OpenAI SDK baseURL at https://api.aijiau.com/v1. Model ids are whatever the console lists.
One key, many models
Fewer upstream accounts. One sk-... selects chat models in the console and can POST /v1/systemone. The catalog moves; trust https://api.aijiau.com/.
Built for agents
Writing models still write plans and replies. Classification, routing, and gates belong on a decision layer. www sends people to /jev and the console — it does not pretend the model is already picked.
Includes Jev System One
Jev is TypeSafe’s decision model. It does not write. The live door is POST /v1/systemone with model jev. chat/completions with jev returns 400. Humans read /jev.
Aijiau’s customer price for Jev is ¥0.6 / 1M input, output free. TypeSafe’s vendor list price is $0.042 / 1M. Chat unit prices live in the console. Do not mash the three into a speed table. This page does not invent QPS.
/gateway explains the model API only. The System One flagship is /jev. Tutorials live on /blog. TaxOps stays off this brand surface. Public CS is [email protected].
Conversion path
www explains. The first live call happens on api.aijiau.com. This page does not invent QPS, and it does not claim the router already uses Jev to pick models.
- Read /jev first. Learn Choice / Score / Noul, and that Jev does not write.
- Open the api.aijiau.com console: sign up and create an sk-.... www /sign-in is the portal login, not the API console.
- POST /v1/systemone with model jev. Do not POST /v1/chat/completions (400). The walkthrough is /blog/first-systemone-call.
Machine shape stays at /jev/docs. Chat getting started lives on /blog. CS is [email protected].
