Vercel AI SDK
createOpenAI({ baseURL })
Use the OpenAI-compatible provider factory and pass baseURL. Streaming responses work with useChat out of the box.
Code
import { createOpenAI } from "@ai-sdk/openai";
const starsea = createOpenAI({
baseURL: "https://starseaapi.com/v1", apiKey: process.env.STARSEA_KEY });
const model = starsea("glm-5.3-flash");Quickstart
- Create an API key — Sign up, then create a token in the console. A key works across the whole catalogue; scope and quota can be restricted per key.
- Point your client at the endpoint — Set base_url to https://starseaapi.com/v1 and use the key. Any OpenAI-compatible SDK, IDE or desktop client works.
- Pick a model — Start with a low-cost tier for prototyping. Every id in the catalogue can be swapped without touching code.
- Watch cost, not just quality — Output tokens are usually priced at a multiple of input, and reasoning models emit thinking tokens. Keep stable prompt prefixes first so caching applies.
