Nerf test

Has your GPT-6 Astra been nerfed?

Switch to GPT-6 Astra, start a new chat, and send it the prompts below one at a time. Then compare each result: the left side is a normal answer, the right side is what a nerfed model typically gives you.

A single run is random. Treat the result as a hint: it cannot confirm which model or route actually answered.
