Bring your own model key (BYOK)
On Pro and Pro+ you can use your own model key in Vara AI (OpenAI, Claude, Gemini, DeepSeek, Kimi, Qwen and more, or any OpenAI-compatible address; Settings → AI → My model). Calls made with your key are billed by your provider and don't count against your Vara quota; image understanding still uses Vara's model. When Pro ends, Vara AI switches back to Vara's models and your saved key is kept.
Using Vara as an LLM gateway from external clients is part of the API plan above and is enabled separately from Pro.
