Questions

Which model API should you call?

OpenAI API is the top-ranked pick at 90. Products that want the broadest model, tool, and SDK support. The score is editorial, not a measured benchmark.

Which LLM APIs tools are free to start?

Gemini API (freemium), OpenRouter (freemium), Groq (freemium), Mistral (freemium), Together AI (freemium), Fireworks (freemium). Dollar prices say “check site” unless the software itself costs nothing to run. Confirm the current plan before you commit.

How does this ranking work?

Capability is 40% of the score, ease 25%, value 20%, and momentum 15%. S is 90 and above, A is 80 to 89, B is 70 to 79, and C is under 70. A sponsored label, if you see one, does not change the number.
