OpenAI's flagship reasoning and computer-use model — strong at drafting, coding, science, and operating software, and the successor to GPT-5.6 Sol.

GPT-6 Astra is OpenAI's flagship model, released on September 3, 2026 as the successor to GPT-5.6 Sol. OpenAI calls it its most intelligent and aligned model and pitches it around a single headline capability rather than benchmark scores: "computer use," the ability to operate a computer the way a person does — clicking through browsers, spreadsheets, forms, and desktop applications instead of only returning text. President Greg Brockman described the launch as a generational leap and said it may mark the start of the AGI era.
In practice Astra is strong across reasoning, software engineering, cybersecurity, science, and professional work. OpenAI's demonstrations range from filling forms and updating a CRM to laying out a printed circuit board in KiCad, building a 3D scene in Unity, animating across FreeCAD and Blender, and drafting a tax return from a W-2. On reasoning tests it reportedly posts large gains — for instance 98.6% on ARC-AGI-3 versus 7.8% for GPT-5.6 Sol — and it is said to nearly saturate the hardest tier of the FrontierMath benchmark.
Access is phased and safety-gated. OpenAI began with enterprise customers, selected partners, and researchers before widening to ChatGPT Plus, Pro, Business, and Enterprise users and to the API, with availability also planned via AWS Bedrock and Microsoft Azure. Because Astra crossed the "critical" cybersecurity threshold in OpenAI's Preparedness Framework, restricted versions refuse advanced cybersecurity tasks and access expands as red-team testing and usage controls keep pace.
One thing to be clear-eyed about: Astra is a text-reasoning and computer-use model, not a media generator. It writes, reasons, codes, and operates software — it produces no images, no video, no captions, and it publishes to no platform. Treat exact pricing, benchmark figures, and rollout details as a launch-window snapshot and confirm them against OpenAI's own pages.
Think of Astra as the writer's room and the analyst, not the studio. It is excellent at the part of content work that happens before anything is publishable: reasoning through an argument, drafting a tight script, generating five hook variations, synthesizing a messy transcript into a clean outline. What it does not do is turn any of that into a finished post. It records no talking-head video, designs no carousel, renders no quote card, and — for all the "computer use" headlines — it does not log into your accounts and publish on brand. That is the exact handoff [Kompozy](/) is built for.
Concretely: take the script, outline, or research Astra produced and drop it into Kompozy as your source. Kompozy rewrites it to your voice through a [Persona Brief](/glossary/persona-brief), then generates the finished formats a reasoning model can't — a captioned [Persona Short](/glossary/persona-shorts) or a HeyGen avatar video narrating the script, a brand-exact [Carousel](/glossary/hyperframes) built from the outline, Quote Graphics pulling the sharpest lines, per-platform Text Posts, a full Blog Article, and an Email Newsletter. Then [Autopilot](/glossary/autopilot) schedules and publishes the whole set across the eight social platforms plus blog and email from one queue, behind a per-post review. The division of labor is clean and repeatable: Astra thinks and drafts, Kompozy produces and distributes — so a stronger model makes your raw material better without changing where the finished content actually gets made and shipped.
GPT-6 Astra is OpenAI's flagship model, launched September 3, 2026 as the successor to GPT-5.6 Sol. OpenAI positions it around "computer use" — operating browsers, spreadsheets, forms, and desktop apps like a person — and describes it as state of the art on computer use, browsing, software engineering, cybersecurity, science, and professional work. Greg Brockman called it a generational leap and suggested it may mark the start of the AGI era.
No. Astra is a text-reasoning and computer-use model — it drafts, reasons, writes code, and can operate software. It does not generate video, images, captions, or carousels. To turn its drafts into avatar video, carousels, quote graphics, and other finished media, you pair it with a content engine like Kompozy that produces those formats and publishes them.
Use Astra to draft a script, outline, or research synthesis, then bring that into Kompozy. Kompozy rewrites it in your voice via a Persona Brief, generates Shorts, carousels, quote graphics, text posts, a blog, and a newsletter, and schedules and publishes them across the eight social platforms plus blog and email — so the model handles the thinking and Kompozy handles the making and distribution.
Astra is available through ChatGPT plans (Plus, Pro, Business, Enterprise) and via the API, with API usage priced per token and consumer access varying by plan. OpenAI is rolling it out enterprise-first behind safety gating, so exact pricing and availability are still expanding — confirm current figures on OpenAI's own pages before relying on them.
