GPT-6 Astra review: brilliant at 3D games and strategy, but unreliable instruction-following blocks daily use
petergyang · x · 2026-09-09
- The author has used GPT-6 Astra as his default model since launch and finds it "both incredible and frustrating."
- Strengths: building 3D games and models, high-level thinking and strategy, computer and browser use.
- Two dealbreakers: it sometimes explains how it would do a task instead of just doing it, and it unreliably follows instructions in his AI skills — even after cleaning them up.
- Current setup: Sol for most execution tasks, Astra for harder tasks or second opinions.
