OpenAI Devs Post GPT-6 Astra Challenge

The official OpenAI Developers account posted a challenge asking what developers can ship using GPT-6 Astra.

The message comes from the company account that shares platform and API updates. Evidence shows only this single tweet; no other details on the model or prior announcements are present.
