Updated 2026-10-14
No free tier is documented for Gemini 4 Argon.
Listed pricing: API intro $2/$10 per 1M tokens through Nov 30, 2026 (cached input 95% off); then $4/$20. Consumers: Google AI Pro or Ultra.
Overview
Gemini 4 Argon is Google's frontier model for deep work on complex tasks: coding, finance, legal, cybersecurity, and science. Google says it supports a 1M unified input-output token limit via the Gemini API.
Developers and enterprises get it through the paid Gemini API tier in AI Studio and the Gemini platform; it is not on the API free tier. Google AI Ultra subscribers can also use it in Google Antigravity. Everyday users get it in the Gemini app and AI Mode in Search with a Google AI Pro or Ultra subscription (Google's Oct 13, 2026 launch post).
If you mainly need light Q&A, a smaller Gemini model is the saner default; Argon is the pick when long context and multi-step professional work are the bottleneck.

Worth it if
The strengths recorded against this entry.
- 1M unified input-output token limit via the Gemini API
- Clear focus on coding, enterprise workflows, legal/finance, and cybersecurity
- API pricing published, with a time-boxed intro rate and 95% off cached input
- Available in the paid API and, for Google AI Pro and Ultra subscribers, in the Gemini app and AI Mode in Search
Not worth it if
Any one of these blocks your use case.
- No free API tier for this model
- API rates double to $4/$20 per million tokens after Nov 30, 2026
- Overlaps with the broader Gemini product brand, so teams must choose which Gemini model they actually need
- Cybersecurity and legal usefulness still depends on your review process; the model is not a substitute for counsel or SOC tooling
