Esta sección está en inglés.
- Gemini API free tier or Groq for an always-on project - both permanent, with published, stable limits you can plan around.
- OpenRouter's free models or llm7.io for model variety without commitment - many LLMs through one OpenAI-compatible endpoint at $0 (llm7.io serves 1M tokens a day).
- Deepgram's $200 credit for speech APIs - the most generous grant we have verified, no card needed.
- Voyage AI's embedding grant for raw token volume - 200M tokens per model, the largest no-strings grant; AgentRouter's $200 remains the biggest one-time all-rounder.
We claim every credit with a fresh account and run our own test requests against it.
- We record the rate limits we actually hit, the models that answered, and whether the card field was skippable at signup.
- We re-check balances and quotas monthly; the verified date on each row is the day we last confirmed the numbers.
- We pull providers that quietly throttle, de-scope, or never deliver the advertised credits - and name them on our scam list where it looks intentional.
