Argon Mode Enforcer for Gemini

Automatically selects the 4 Argon model and sets the thinking level to High on gemini.google.com.

Argon Mode Enforcer for Gemini automatically selects the "4 Argon" model and sets the "Thinking level" to "High" whenever you open or start a chat on gemini.google.com. Stop manually opening the model picker and expanding the thinking menu on every new session. This lightweight utility ensures you are always running on maximum reasoning effort by default. KEY FEATURES • Automatic Model Selection: Detects the Gemini header mode switcher and switches to "4 Argon" automatically. • Maximum Thinking Effort: Expands the "Thinking level" menu and locks in "High" thinking mode. • Multi-Account Safe: Automatically detects if your current Google account does not have access to the 4 Argon model and stops cleanly without looping or interfering with your session. • One-Click Pause/Resume: Includes a minimal dark-mode toolbar popup to toggle automatic enforcement on or off anytime. • 100% Private & Local: Runs entirely in your browser on gemini.google.com. Zero analytics, zero tracking, no external servers, and no user data collection. NOTE & REQUIREMENTS • This extension does not unlock or grant access to gated models—your Google account must already have access to 4 Argon on gemini.google.com. • This is an independent, unofficial utility and is not affiliated with, endorsed by, or sponsored by Google LLC.
