Apps that work with BigModel.io

Coding agents, chat clients, workflow tools, SDKs and creative apps that work with one BigModel.io key, with the base URL and setup steps for each.

Coding agents

Developers who let an agent read, write and run code in a terminal or editor. Agents send long contexts and many tool calls, so per-key spend limits are worth setting.
