Cursor can call Moxus AI through a custom OpenAI API key and Base URL. This mainly affects Chat, Composer, and Agent workflows. Tab completion behavior depends on Cursor’s current version and plan rules.

​
How to use it

  • Cmd/Ctrl + L: open chat for code explanation and project questions.
  • Cmd/Ctrl + I: open Composer for code edits.
  • Agent mode: useful for multi-file tasks, but it may produce more requests and higher cost.
Cursor Free may only allow Auto mode. Providing your own API key does not necessarily unlock manual model selection inside Cursor.

​
Troubleshooting

This is a Cursor plan limitation, not a Moxus AI key error. Switch to Auto or upgrade Cursor before selecting a specific model manually.
Add the exact model name from Models and pricing. Do not use embedding models such as text-embedding-3-small for coding chat.
Open Usage and check whether the request reached Moxus AI, which key was used, and which model was called.
