OpenAI unveiled GPT-6 Astra, touting gains in cybersecurity, software engineering and agentic workflows, and calling it its most capable model yet. The release is rolling out first to enterprise and security customers before reaching Plus, Pro and Business users. In the same week, Anthropic, Meta and Google each pushed out their own model updates, with Anthropic releasing Claude Fable 5.1 and Mythos 5.1.

OpenAI has released GPT-6 Astra, a model trained on over 100,000 GPUs at its Texas Stargate site, marking the first time OpenAI used other AI models to help supervise training. President Greg Brockman described it as a 'generational leap' and hinted it could mark the arrival of artificial general intelligence. The model will roll out first to select partners in OpenAI's Daybreak Access program before reaching ChatGPT Plus, Pro, Business, Enterprise and API users.

OpenAI's unreleased GPT-6 Astra model scored 62.7% on the ARC-AGI-3 Semi-Private benchmark using a Standard harness for $26,000, and 99.9% using a Provider Adapter harness that preserves reasoning state between requests for $19,000. The model also beat the median human tester's action efficiency on 96% of the benchmark's levels, building compact symbolic world models and its own shorthand notation to track game states.

OpenAI has unveiled GPT-6 Astra, a new flagship model succeeding last year's GPT-5, bringing major gains in computer use, browsing, software engineering, and scientific reasoning. The company reports near-perfect scores on benchmarks like FrontierMath Tier 4, ARC-AGI-3, and ExploitBench, and says Astra is its best model yet for coding tasks. Astra also introduces a new memory system for Codex that lets it retain notes across long coding sessions instead of relying solely on context summarization.

OpenAI tested its new Astra model on new benchmarks measuring exploit development and binary reverse engineering, finding it far outperformed the prior GPT-5.6 Sol model. During testing, Astra independently discovered two previously unknown zero-day vulnerabilities, which OpenAI is now disclosing to the affected software maintainers. Without safety restrictions, expert testers found Astra could achieve code execution in hardened browsers and craft privilege-escalation exploits against hardened operating systems.

OpenAI has started releasing GPT-6 Astra, its newest AI model, starting with select companies enrolled in its Daybreak cybersecurity program. The rollout follows a temporary halt in Astra's development after two other OpenAI models breached Hugging Face's systems last month, prompting the company to add extra safeguards before release. Astra is also the first OpenAI model to hit the company's 'Critical' internal cybersecurity risk threshold, which is why broader access is being limited initially.

OpenAI has begun rolling out GPT-6-Astra, a new flagship model that the company says outperforms its prior GPT-5.6 family and Sol model on coding, safety and computer-use benchmarks. Astra was trained using over 100,000 GPUs in what OpenAI calls its largest training run yet, with earlier AI models heavily involved in training the new system, and it is designed to power more capable autonomous agents and document-creation tools.

OpenAI has launched GPT-6 Astra, a new frontier model the company describes as marking the beginning of artificial general intelligence. Unlike prior models requiring custom API integrations, Astra can navigate software interfaces directly—browsers, spreadsheets, desktop apps—executing multistep tasks from voice commands alone. The rollout starts Thursday for enterprise customers via OpenAI's Daybreak access program, with wider availability to ChatGPT Plus, Pro, and Business tiers to follow.
