metellingtruth · reddit · 2026-11-14
A Reddit post shares a Google Gemini Apps Help page screenshot (marked subject to change) revealing the model matrix per subscription tier:
- New model codenames Hydrogen, Argon, and Carbon appear alongside Flash-Lite and Pro
- Carbon is only available on Google AI Ultra (for both chats and tasks); Pro-tier Tasks are limited to Hydrogen and Argon
- With auto model selection on, most prompts use Flash-Lite, while harder reasoning may use Hydrogen
The poster notes Pro users appear to be missing out on Carbon, sparking discussion about tier value changes. Unconfirmed, based on an official help page screenshot.
