Gemini 4 Argon first impressions: near Opus 5.5 but hallucination rate questioned
brandon_galang · x · 2026-10-15
Developer brandongalang shares first impressions of Gemini 4 Argon via Cursor:
- Hard to distinguish from his daily driver Opus 5.5 on already-scoped tasks, though slightly slower
- Effective at gathering and synthesizing context across many threads
- Distinct writing style, not Claude- or GPT-coded
- Plans to use it as an extra review agent in planning sessions for model diversity
- Cites Theo's finding of an absurdly high hallucination rate that conflicts with its AA benchmark, questioning its trustworthiness
- Not in the Antigravity Pro tier, limiting personal use
