Google AI Pro subscribers locked out of Gemini 4 Argon in Antigravity, sparking $20-tier backlash
RealSpecialist7083 · reddit · 2026-10-14
A Google AI Pro ($20/mo) subscriber complains that after Gemini 4 Argon's release, Antigravity IDE/CLI offers Pro users only Gemini 3.8 Flash — Argon is gated behind the $100+/mo Ultra plan (screenshot shows Argon marked "Unavailable", Ultra-only).
Key points:
- Flash falls apart on real agentic coding: hallucinations, loops, breaking adjacent files, failing to fix one bug after 10+ attempts. An "agent-first IDE on a lightweight model" is useless for serious work.
- Rivals give flagship models at $20: Claude Pro (flagships in Claude Code), ChatGPT Plus (full Codex), Cursor Pro (top models out of the box).
- No request for unlimited tokens — but zero Argon quota, not even a capped daily/weekly limit, feels like treating Pro users as free-tier testers.
- The author, on a regional discount ($6/mo), is ready to ditch Antigravity for Claude/Codex at full price.
Also cites Google's claims of 77.9% DeepSWE and 100K Alphabet employees using Argon internally.
