Gone, misread or unconfirmed
- The $300 Google Cloud free trial can't pay for the Gemini API in AI Studio (Google Cloud docs).
- Anthropic gives no free credit on API signup: see free Claude API credits.
- GitHub Models was fully retired on July 30, 2026 (GitHub docs).
- We found no official free signup credit for DeepSeek. It does charge half price off-peak: see pay less per token.
- Dollar amounts quoted elsewhere for the Anthropic and OpenAI startup programs aren't on their official pages, so we don't repeat them.
When free runs out
Free tiers cap requests, and startup credits expire. For paid usage, compare what a dollar of usage costs at each place to buy, and cut the token bill with batch and caching.
