Meta's post, curated on eChai

Founder Notes

Curated from engadget.com · 16 June 2025 →

Meta's standalone AI app, launched in April 2025, has a Discover feed carrying conversations people have shared. Through May and June it filled with things nobody appears to have meant to publish: medical questions, home addresses, court details, someone asking how to evict a tenant. The share control looked like the share control in every other Meta app, where sharing is the ordinary act, and here it published a private conversation to strangers. The text quoted above is the warning Meta added afterwards. Same failure as the OpenAI case above and worth reading with it: neither was a breach, both were a consent flow that people walked through without understanding what they had agreed to.

Vaibhav Srivastav is at OpenAI, and was at Hugging Face before that, so this is written from inside the team that shipped the model. The five lines in the middle are the part to keep: what to change in your own prompts and AGENTS.md now that Astra follows instructions more closely than the model before it.

GPT-6 Astra is now available to all Pro, Enterprise and Business Premium users in ChatGPT Work and Codex. It’s also live in the API.

It's a phenomenal model and I love every second working with it!

Astra follows instructions more closely, so revisit your prompts and skills:

> Make “can you…” mean “do it”: finish authorised work and prepare a reviewable result before seeking approval.

> Audit AGENTS.md and skills. Ask it to identify the exact file and rule blocking progress. Prioritise your request over skill guidelines.

> Specify short paragraphs, plain language and phrases to avoid.

> Ask for subagents on independent work when it improves speed or quality.

> Run relevant checks. Repeat or expand only for changes, failures or unresolved concerns.

To push it to it's limits, I gave it a prompt to build a real-scale video fly through of nürburguring track in blender and it did not disappoint!

Enjoy! ✨

Miguel Ángel is a product engineer at HeyGen, and HyperFrames is HeyGen's own product, so this is the model being used on the thing he builds all day.

Astra is so cracked at Blender.

You can literally one-shot game assets with it.
