[Gemini 4 Argon Appears in Antigravity's New Version, Three-Tier Inference Configurations Ready but Still Unavailable] According to Golden Finance, on October 13, the 2.23.0 update of Google's AI programming tool Antigravity revealed the full model identifiers for Gemini 4 Argon, including Low, Medium, and High three-tier inference configurations. These were absent in the previous version 2.22.0. The new version added four model IDs and three model selection menu names, but these configurations are currently hidden in the program code and cannot be directly selected by regular users. At the same time, Antigravity removed several older models: Gemini 3.1 Pro, 3.6 Flash, and 3.7 Flash were marked for deprecation on October 12, and the next day users noticed that the Gemini model list only retained 3.8 Flash. Another developer discovered that the three Argon tiers are already ranked among the top three in the client’s recommended model order, but requests to the corresponding interface still return a 404 error. Google had already announced Argon on September 30, initially making it available primarily to selected cybersecurity partners. Plans are in place to later extend access to paid API users and Google AI Ultra subscribers.
