Cursor & Windsurf
Both editors accept an OpenAI-compatible base URL, so they work with Primex directly.
Settings
In the editor's AI / model settings, set an OpenAI-compatible provider:
| Field | Value |
|---|---|
| Base URL | https://gateway.primexos.com/v1 |
| API Key | prx-YOUR_KEY |
| Model | e.g. gpt-5.5, gpt-5.3-codex, claude-opus-4-8 |
That's it. Completions and chat now bill through your Primex account.
Continue / Cline
For Continue, select an OpenAI-compatible provider, point apiBase at
https://gateway.primexos.com/v1, and set apiKey to your prx- key.
Primex's verified Cline workflow uses its Anthropic provider with a live
Claude model, https://gateway.primexos.com as the base URL, and your prx- key.
See Messages. Client versions may expose different settings;
start with a small request before relying on a full agent workflow.
Tips
- Pick a passthrough model (
gpt-5.5,gpt-5.3-codex) for agentic/tool-heavy work. See Responses. - Use
gpt-5.4-mini/gpt-5.4-nanofor cheap autocomplete and quick edits.
