OpenAI isn't the only option anymore. The 12 providers below offer comparable models — often faster, often cheaper, sometimes with better reasoning. All have real free tiers.
Why look beyond OpenAI?
- Cost — OpenAI charges $2.50/M for GPT-4 input. DeepSeek charges $0.14/M.

- Privacy — Some providers (Mistral, Cohere) offer EU data residency.
- Open weights — Self-host Llama, DeepSeek, or Mistral for full control.
