What the feature labels mean Documented Explicitly shown in public documentation. Conditional Depends on model, request shape or separate endpoint testing. Not verified We found no sufficient public evidence in this review.

Evidence boundary

Documentation review proves a configuration path. It does not prove TokenAir model quality, streaming, tool calling or image behavior in that tool.

Documented verdict

A limited setup path exists through Cursor's OpenAI API key and Override OpenAI Base URL settings. Treat it as a chat-model experiment, not a replacement for every Cursor model or feature.

Important limitations

Cursor states that custom API keys apply to standard chat models only. Specialized features continue to use built-in models.
Cursor support has documented base URL scope and request-shape issues for some model paths. Current behavior can change by release.
If the override applies to all models in your build, mixing TokenAir and Cursor-hosted models may require toggling it off and on.

Check your own relay

LIGHTWEIGHT BROWSER CHECK

Check relay protocol integrity

Run three low-token checks that reveal whether an OpenAI-compatible relay preserves the response, streaming, and tool-call behaviors users rely on.

Basic response, usage and returned model metadata
SSE event stream and proper [DONE] termination
Forced tool call with schema-valid arguments
