Verdict
When to choose each
Gemini 4 Argon
Where it leads
- Accepts video input
Best for
- Long-horizon coding and knowledge work once it reaches general API access
Watch out for
- The $2 input and $10 output rates are introductory and end on November 30, 2026; from December 1 Google charges $4 and $20 per 1M tokens
- Not on the Gemini API free tier, and explicit context caching is not supported; implicit caching takes 95% off repeated input
- Answers longer than 64K tokens need background execution, and Google advises client timeouts of at least 15 minutes for hard prompts
Gemini 4 Carbon
Where it leads
- Higher Arena Text score, 1528 Elo vs 1520 Elo
- Higher Arena WebDev score, 1768 Elo vs 1679 Elo
Best for
- Finding, validating and patching vulnerabilities, for teams in Google's Fairwind Program
- Long-horizon engineering over very long inputs, once access opens
Watch out for
- Limited access: Google gives it first to a small group of cyber defenders, then to more trusted partners through its Fairwind Program, which governments, healthcare providers and telecoms apply to; there is no public API or app access yet
- The $2 and $10 rates are introductory, with cached input 95% off; after an introductory period Google has not dated, $4 input and $20 output per 1M tokens apply
- In Google's own table it trails GPT-6 Astra on FrontierSWE 2 (61.2% against 65.5%) and Claude Opus 5.5 on OSWorld-2.1 (81.5% against 87.2%)
- Google publishes no context window or output limit for Carbon yet
