GPT-6 Astra is OpenAI's most capable model for complex reasoning, software engineering, computer use, science, and professional work. Async tool calling and mid-turn steering help it run multistep agent workflows. API: model id gpt-6-astra, $10/$50 per 1M tokens (short context). Rolling out first via Trusted Access/Daybreak, then Plus, Pro, Business, Enterprise, and the API in the coming days. First OpenAI model at the Critical cybersecurity capability threshold (advanced cyber access limited).
the "Critical cybersecurity capability threshold" line is the part I keep coming back to. gating advanced cyber access sounds responsible on paper, but it also means whoever gets into that access tier ends up with a real offense/defense edge over everyone still on the standard release. genuinely curious how the eligibility bar is set for that tier and whether there's any independent check on it, or if it's OpenAI's own call end to end.
Whatever happened to Product Hunt not allowing pre-release / unlaunched products on the home page?
the mid-turn steering part is what I'm most curious about. for tool calls you can undo, steering mid-turn is just a nicer UX. but once a step in the workflow is something external and already committed (a payment call, an email sent, a phone call already ringing), can you still steer the model away from a plan it already started executing on, or does steering only work for the parts that haven't left the sandbox yet
Could users set priority rules so the model knows which goals should always take precedence?
Fyi message from Thibault Sottiaux: "We will give one banked reset for every day you don't have access to Astra on your paid ChatGPT plan, starting today. Team is moving mountains to give access as fast as we can."
The mid-turn steering alone makes this feel like an actual coworker instead of a slot machine.
Hey PH community 👋
Excited to hunt GPT-6 Astra today.
The frontier labs keep pushing each other. We saw what Fable 5.1 did earlier this week:
This is OpenAI's next flagship, built for the hard end to end work. Coding, computer use, science, and long agent workflows that actually stay on track.
Async tools and mid turn steering mean it can keep going while you course correct mid task. Feels less like a chat box and more like a teammate that can drive the machine.

Who hunted GPT-6 Astra?
GPT-6 Astra was hunted by KP. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Mid-turn steering + async tools is a great qol improvement, a much more natural way of interacting.
