Getting started
AI providers and keys
Which provider to choose, what it costs, how fast it is, and where your key is kept.
Canvex does not include AI credit of its own. You bring a key from one of five providers, and generation is billed to that key by the provider.
| Provider | Model used | Cost | Notes |
|---|---|---|---|
| OpenRouter | Free models, discovered daily | Free; 50 requests a day, 1,000 after buying $10 of credit | Free models change often and are rate-limited; Canvex tries the next one automatically. A canvas can take several minutes. |
| Claude (Anthropic) | Claude Sonnet 5.5 | A few US cents a canvas | The most consistent results, typically 30–60 s a canvas. Needs API credit, which a Claude Pro or Max subscription does not include. |
| OpenAI | GPT-6 Luna | A fraction of a cent a canvas | Fast and inexpensive. Older keys fall back to GPT-4o mini. |
| Gemini (Google) | Gemini 3.8 Flash | Free tier, then pay as you go | The free tier allows only a few requests a day. Falls back to 3.5 Flash-Lite. |
| Kimi (Moonshot) | Kimi K2.6 | Pay as you go | Falls back to Kimi K3. |
Where your key is kept
Your key is stored in your browser only, one per provider, and sent with each generation request. It is never written to Canvex's database, and it is not part of your account — so on a new device or browser you paste it once again.
