GPT-6 Astra versus Fable 5.1 on 15 real tasks
A comparison done with real work, not a lab benchmark.
The comparison put GPT-6 Astra and Claude Fable 5.1 through 15 real-world everyday tasks. It assessed the quality of the results, cost, and time, rather than relying only on laboratory tests. In the overall score, Astra won 10 tasks and Fable won five.
Astra performed better on work with multiple steps, such as tax tasks, meeting analysis, browser automation, and creating a 3D game. Fable did better at writing, research, and faithfully following a reference. Across the tests, Astra cost about US$186 less but took approximately 1 hour and 43 minutes longer. For users, the choice depends on the type of work and how much weight they give to quality, cost, and speed.

The author prefers Astra for daily use but keeps Fable for work that calls for depth or a strong first result.
