OpenAI's ChatGPT Astra explained: What it is, features, plans, benefits and how it differs from previous models

OpenAI has released its newest and most powerful AI model, GPT-6 Astra, which places a main focus on computer-related tasks, coding, research and complex professional tasks. Astra is not just a tool for answering questions but a tool that can execute multiple steps of work on a computer. It is now available to ChatGPT Plus, Pro, Business and Enterprise users and will be rolling out over the next few days.

It is a major step up from the previous-generation GPT-5.6 Sol. According to OpenAI, Astra offers enhanced reasoning capabilities, better task execution and improved user intent understanding. It can access websites, interact with documents and spreadsheets, develop software, analyse data and automate computer-based processes with minimal human interaction.

What does 'ChatGPT Astra' mean?

GPT-6 Astra is OpenAI's latest and greatest model for complex, end-to-end tasks. It is designed to work through a problem, rather than just provide an answer, and to apply tools to complete the task.

Key capabilities include:

• Computer control and browser navigation
• Advanced programming and software development
• Complex research and data analysis
• Create documents, presentations and spreadsheets
• Long-context processing
• Improved visual understanding
• Multi-step professional workflows

According to OpenAI, Astra can perform online research, fill out online forms, update CRM data, organise calendars and more.

How powerful is the GPT-6 Astra?

Compared to GPT-5.6 Sol, the model provides significant improvements on several of OpenAI's tests. On ARC-AGI-3, Astra scored 99.9%, compared with 7.8% for GPT-5.6 Sol. Astra outperformed its predecessor with a 72.6% rating on OSWORLD 2.0, a computer-use test.

OpenAI also mentions that the API version has a 1.05 million-token context window, which makes it more appropriate for large projects and long-running workflows, whereas Astra is better for smaller workflows.
