I’m now making a World of Warcraft inspired single-player RPG with some RuneScape elements for the browser with GPT-6 Astra. I literally had the idea while drinking my morning coffee and thought… while I have another Astra project to develop treatments for cancer is ongoing, why not start this too! 😅

It’s still a very early version, but it’s already actually playable! Combat works, you can chop down trees and gather resources, and I’m starting to build out the world, progression, quests, loot, item tables and other RPG systems. I know this will surprise some but I used to be a serious gamer, I just know this stuff hah!

Maybe I’ll eventually turn it into an MMORPG so we can form rival Codex vs. Claude vs Grok guilds, but no cheating with the AI bots. 😂

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.
