Gemini 4 Argon • Not a free API • AI Pro trial does not include Argon in Antigravity • Paid Pro gets it in the Gemini app • API is paid, no free tier Links in the comments. Free APIs keep appearing. I'll keep testing and sharing the ones actually worth using. Disclaimer: Third-party services. Offers, models, limits, and availability can change.
