Summary
This is a reference table for LLM providers with actual permanent free tiers, not trial credits that expire. It covers both first-party APIs (Gemini, Mistral, Cohere) and inference providers hosting open models (Groq, Cerebras, OpenRouter). Every endpoint listed is OpenAI SDK-compatible, so you can swap providers by changing two lines of code. The rate limits are documented upfront, which saves you from hitting walls during prototyping. Useful when you need to compare what you can actually build for free or want a fallback provider without spinning up your own inference stack. The code examples are copy-paste ready with proper environment variable handling.
