OpenAI / Anthropic APIs

Current free tier

What's free

OpenAI: a daily free-token allowance if you opt in to sharing your API data (up to ~1M tokens/day on frontier models, ~10M/day on mini). Anthropic: a one-time $5 trial credit.

Limits

OpenAI: daily, opt-in only; Anthropic: one-time

The catch

OpenAI's free tokens cost you your data. Anthropic's $5 needs SMS verification and is a trial, not a tier. The old OpenAI $5 welcome credit is gone.
