Basic specifications of the new model that supports 'thinking, researching, and creating' in ChatGPT","summary":"Unlike previous models, Astra organizes information, makes judgments, and chains processes like reading a document, researching gaps, and compiling a report into a single workflow. It includes a **reasoning.effort** setting (low to max) to adjust depth for tasks like comparing conditions or analyzing code, with higher effort increasing time and usage costs.\n\nAstra is not yet available to all ChatGPT users. As of September 2026, it powers **GPT-6 Pro** for **Pro, Business, and Enterprise** plans, while **Plus** users access it via **ChatGPT Work and Codex**. Availability depends on location, plan, and app environment. The model can browse the web, operate applications, and generate code—but users must verify outputs, permissions, and actions for accuracy, especially for critical tasks like deletions or purchases.","keyPoints":["GPT-6 Astra combines reasoning, browsing, coding, and document creation into multi-step workflows, not just text generation","Reasoning depth is adjustable via **reasoning.effort** (low to max), affecting response time and usage costs for complex tasks","Available only to **Pro, Business, Enterprise** (GPT-6 Pro) and **Plus** (via Work/Codex) users, with rollout dependent on location and app"],"whyItMatters":"Astra shifts focus from single-answer AI to task automation, potentially reducing manual work for research, coding, and report generation—but requires user oversight for accuracy and permissions.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":[],"models":["GPT-6 Astra","GPT-6 Pro","ChatGPT"],"people":[]},"firstPublishedAt":"2026-09-21T21:41:00Z","updatedAt":"2026-09-23T15:07:00Z","sourceCount":2,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"What has changed with GPT-6 Astra?
