Astra is live: Six prompts to try first

OpenAI’s GPT-6 Astra is live.

If your model picker still looks like yesterday, you are not broken. You are early in a messy queue — Pro, Enterprise, Business Premium, and the API are already getting Astra, while Plus is still rolling.

What you need to know

• Name: GPT-6 Astra (API id commonly referenced as gpt-6-astra).
• Who: Confirmed live for ChatGPT Pro, Enterprise, and Business Premium, plus the OpenAI API, Microsoft Azure, and AWS Bedrock. Plus is still rolling; Free is not in the announced ChatGPT Free lane.
• Astra Pro: A higher-effort Astra option is part of the Pro / Business / Enterprise story — treat it as the “think harder” lane, not the default Plus picker.
• Free tier: Not in the announced ChatGPT Free lane. Paid seats only for the broader ChatGPT rollout.
• Enterprise catch: Workspace admins may need to flip Astra on; it can ship off by default.
• Compensation while you wait: OpenAI has been banking usage resets for paid ChatGPT users who still cannot select Astra during the messy rollout.

Six prompts to paste the second Astra appears

These are built to show judgment, not party tricks. Paste one, then tighten the brief mid-run and see whether Astra stays on rails.

1. 3D world

Create a single HTML file using Three.js that renders an explorable low-poly island. Requirements: procedurally placed trees and rocks from a seed, animated water, a day/night cycle with a moving sun and stars, a flock of birds using boids-style flocking, a weather system where rain fills visible puddles and wind bends the trees, first-person WASD + mouse controls, an on-screen panel to change terrain seed, tree density, time of day, and weather live, and an export button that saves the current scene as an OBJ file with materials. No external assets — generate everything in code.

2. Self-verifying logic puzzle

Invent a five-houses logic puzzle with 12 clues, exactly two of which are false. Present all 12 clues, identify the two lies, and solve it. The puzzle must have a unique solution only once the lies are removed, and must be contradictory if all 12 are taken as true. Then write and run a program that brute-forces every possible assignment and every pair of discarded clues, and confirm exactly one (lie pair, solution) combination survives. Show the program's output.

3. Double-constrained story

Write a 300-word story where every sentence has exactly one more word than the one before it, starting with a one-word sentence, and the final word of the story equals the first. Additionally, the story must be structurally palindromic: sentence 1 and the last sentence share a theme, sentence 2 and the second-to-last share a theme, and so on, with the middle sentence as the turning point. Afterward, list each sentence's word count and each mirrored pair's shared theme.

4. Three audiences with self-critique

Explain why the sky is blue in three parallel columns under 120 words each: for a curious 7-year-old, for a college physics student, and for a skeptic who believes the sky reflects the ocean. The skeptic's column must directly dismantle their belief. Then write the strongest objection a working physicist would raise against your student-level column, and rewrite that column to survive the objection.

5. Adaptive teaching game

Build a playable browser game in a single HTML file that teaches Bayesian updating without ever showing the words 'Bayes,' 'probability,' or 'prior.' The game must model the player: track whether they're overconfident or under-updating and adjust evidence noise in real time accordingly. The final screen must reveal what they learned and show them a chart of their own bias over the course of the game.

6. Long-horizon mystery

Write the first chapter of a mystery novel (about 1,500 words), then a detailed outline of chapters 2–11, then the full final chapter. The final chapter must resolve every clue planted in chapter one, and at least three of those clues must have been disguised as irrelevant details. Afterward, produce a table listing each clue, where it was planted, and where it paid off.

The one move

When Astra shows up in your picker, do not start with “write a poem.” Run one hard job you already know how to grade — a 3D world you can walk, a puzzle that verifies itself, a constrained story, a teaching game, or a mystery that pays off its own clues — and decide in twenty minutes whether this model changes your stack or just your screenshots.
