OpenAI’s GPT-6 Astra Sits Down at Your Computer

On September 3, OpenAI began rolling out GPT-6 Astra, which the company describes as the most intelligent and aligned model it has ever released. Access begins with a small number of organizations and will gradually spread to ChatGPT Plus, Pro, Business, and Enterprise accounts over the next few days. Developers can refer to it as gpt-6-astra whether utilizing the OpenAI API, Microsoft Azure, or AWS Bedrock.

The model is available with paid plans that include usage. Anything exceeding that, however, will result in credits being burned. The API pricing is given below: $10 for every million input tokens and $50 for every million output tokens. There’s also a “Fast mode” that doubles the price. Do you know what? It provides nearly twice the speed. Context gains 1,050,000 tokens. Output is limited to 128,000 tokens, and Knowledge stops at April 30, 2026.

Computer use sits at the center of the pitch. Astra sits in front of a screen, moves the cursor, types, and performs tasks that would normally need a human at a desk. It can fill out web forms, update CRM information, organize calendars, install software, perform all of the checks to ensure everything is in place, and continue working even if a certain task necessitates the use of several apps. In OSWorld 2.0, Astra scored 72.6 percent and completed each job in approximately 40 minutes. Meanwhile, GPT-5.6 Sol scored 65.7% and required approximately 75 minutes. That’s 47 percent less time for the same score as GPT-5.6 Sol. Agents’ Last Exam scored 59.3 percent, whereas ScreenSpot-Pro scored 92.7 percent without using any additional tools.

The launch materials include information about common use cases. For example, Astra can use Google Maps to identify a pediatrician, go to the clinic’s website, and fill out a new-patient form. Astra can now do cat-sitter research in about five minutes, down from a half-hour before. The same is true for job searches, which Astra can now finish in less than three minutes, down from five hours previously. The same applies to tax preparation, apartment hunting, legal memo formatting, and architectural rendering.

Of course, Astra’s offering includes specialized software. It can design circuit boards in KiCad, build buildings in Blender, and create sceneries in Unreal Engine. We also have examples that explain how to turn a rudimentary design into a 3D city block and create a playable voxel map of medieval London over different eras. Visual judgment skills for websites, games, and applications have advanced to the point where ChatGPT’s Sites feature can use Astra to create cleaner layouts. Long coding sessions provide additional context as you work on them. An experimental note-taking habit attempts to transport facts between windows rather than compacting them away.

OpenAI handled cybersecurity as both a selling point and a caution. Astra is the first OpenAI model to reach the company’s Critical criterion. That implies it can discover unexpected holes and create new attacks on well-protected systems with less step-by-step assistance. ExploitBench received 100 percent. SRE-Bench achieved 88 percent on the first try and 99.2 percent after four attempts. Offensive work remains under lockdown.
