Real-world GPT-Astra review: exceptional long-horizon autonomy, writing finally clicks
EXM7777 · x · 2026-09-06
A first-hand review of GPT-Astra from actual business use (not the trendy 3D/game demos):
- The most pleasant OpenAI model to talk to, with Opus 4.5 vibes
- Exceptional at setting its own goals and orchestrating subagents through long-horizon work
- Still behind Fable on frontend design
- "Stupidly good" at using the computer — will unlock insane workflows
- Much better at writing: "they finally cracked it"
- Efficient usage, hits limits slowly
The author skipped games/3D testing entirely and is busy deploying it in their businesses.
