Every's Vibe Check: GPT-6 Astra Is a Big Upgrade, but Anthropic's Fable Still Has Better Product Instincts
every · x · 2026-09-04
Every published a hands-on "Vibe Check" of OpenAI's GPT-6 Astra:
- Striking writing: Astra drafted the entire review from a single prompt; CEO Dan Shipper mistook it for staff writer Katie Parrott's own work ("RIP my job").
- Strengths: writing, operating software / computer use, and visual design.
- Weaknesses: the verdict is that Anthropic's Fable still has better instincts for building a product.
The piece includes full benchmark comparisons and a paid members' camp pairing Fable 5.1 with Astra. Overall: a big upgrade, but not a clean sweep over Anthropic's flagship.
