Fable 5.2 vs GPT-6 Astra tested with the same prompt
The author tested Fable 5.2 and GPT-6 Astra with identical prompts and no extra context, finding that Astra completed the task but Fable 5.2 produced a more detailed and complete output.
Fable 5.2 absolutely crushed GPT-6 Astra in a fair fight with the exact same prompt. GPT-6 Astra and Fable 5.2 were tested on the same task using identical instructions. No extra context. No tweaks. No hints. Just the exact same prompt given to both models. The difference was much bigger than expected. Astra completed the task, but Fable 5.2 delivered a dramatically stronger result - better execution, more detail, and a much more polished final output. It’s a good reminder that a newer model doesn’t automatically perform better at every type of task. Sometimes, one identical prompt is enough to reveal a huge gap between two models.
