Early GPT-6 Astra hands-on: fast and cheap, but still needs heavy steering

Between September 9 and 11, developers posted early hands-on impressions of GPT-6 Astra. revodavid led with assessments of speed, pricing, and one-shot development capability, overall positive; zeeg and Saai Arora then added comparative observations against Sol, noting limited gains in token usage and task quality and continued need for heavy steering in system design.

Confirmed

• Speed: revodavid found generation via GitHub Copilot faster than expected, with wait times only slightly longer than Sol.
• Pricing: cheaper than expected, at 1x rate, same as Sol and Sonnet.
• One-shot capability: revodavid used a 5-line prompt to one-shot generate and run the Platonic-solid interactive teaching app "Becoming" in about 10 minutes; the final version took only about 1 hour of manual time.
• App details: "Becoming" features dual-path display (faces decreasing/vertices increasing) and drag-to-rotate-zoom interactions; the one-shot result matched his original concept, refined over hours of follow-up prompting.
• Token usage: both zeeg and Saai Arora reported no meaningful speedup in token consumption versus Sol and no perceptible quality gap on most tasks; Saai Arora noted slightly higher usage.
• Steering: both agreed that producing good system designs still requires considerable human steering for both Astra and Sol.
• Tone: zeeg added that Astra's replies are "less annoying" than Sol's.

Why it matters

• Astra's performance in a real dev toolchain (GitHub Copilot) at Sonnet-parity pricing makes it directly comparable in the coding-model race, and its ability to one-shot a working app from a minimal prompt shows strong rapid-prototyping potential. Yet developers unanimously note that system design still demands heavy human involvement, suggesting "fast and cheap" does not equal autonomous complex design, and real efficiency gains should be viewed rationally.
