2026/9/4 23:58 (UTC+8) · New Model · Google 🚀 New Gemini_Reverse group: a Gemini reverse-engineered economy channel at a 0.5x discount Background: Gemini_Reverse draws on reverse-engineered channels from Gemini CLI and Antigravity (Reverse Sources) and bills at 0.5x, half the official price. Take gemini-3.8-flash as an example: the official price is $0.75 input / $3.75 output per 1M tokens, and this group bills at $0.375 / $1.875. Select the Gemini_Reverse group when creating a token in the console; model names and endpoints are the same as on the default group. Gemini models now come in two groups, pick by need:
  • default official-relay group: official AI Studio and Vertex resources, priced line for line with the official rate; for production workloads and tasks that need stability
  • Gemini_Reverse group: Gemini CLI / Antigravity reverse-engineered resources at a 0.5x discount; for personal learning, coding and other cost-sensitive use, with availability following the reverse sources
See What are groups? User groups vs token groups for how groups work, and the Gemini 3.8 Flash page for pricing.
