Google AI Ultra: $100/Month Plan Creates Three-Tier Agent-Compute Pricing for Developer Tools

CyberNews·medium signal

Google introduced a new $100/month AI Ultra plan at I/O 2026 with 5x the Antigravity usage limits of the $20/month Pro plan, while simultaneously confirming that free-tier consumer access to Gemini CLI and Gemini Code Assist IDE extensions will cease on June 18, 2026. This creates a clear three-tier pricing structure (Free → Pro $20 → Ultra $100) differentiated primarily by agent compute allocation, not features. The signal for the industry: agent-compute consumption is becoming the primary pricing axis for developer tools, replacing seat-based or feature-gated models.
