Providers with free tiers
Try MultiScreenAI without paying: these providers offer free usage or trial credits.
Many AI companies give out free API keys. The full, up to date list with limits and step by step setup is on the Free AI keys page.
The quickest free starts
- Google Gemini: a free tier in Google AI Studio, no card.
- Groq: 30 requests a minute and 1,000 a day, very fast.
- OpenRouter: free models ending in "free", 50 requests a day, or 1,000 after a one-time $10 top up.
- Vercel AI Gateway: $5 of free credit every 30 days that works on GPT, Claude and Gemini too.
Add several free keys and put their models side by side. Each provider's limit is separate, so together they go much further.
Free tiers have tight limits. If you see a quota error, read Quota and rate limit errors.
