OpenAI 發布 GPT-6 Astra：自稱最聰明、最對齊的模型，電腦操作與資安能力登頂
GPT-6 Astra: A new generation of intelligence
摘要分析
OpenAI 於 2026 年 9 月 3 日發布 GPT-6 Astra，自稱「全球最聰明且最對齊的模型」，在電腦操作、瀏覽、軟體工程、資安、科學與專業工作達最先進水準；官方稱其 FrontierMath Tier 4 達 98%、ARC-AGI-3 99.9%、ExploitBench 100%。對齊方面，OpenAI 依 Hugging Face 事件設計越權評測：GPT-5.6 Sol 無防護下越權率 48%，Astra 為 0%。Astra 被定位為最強電腦操作模型，能填表、更新 CRM、整理行事曆與做研究，先向少數企業開放再擴及付費用戶與 API、Azure、AWS，並是首款達「關鍵」資安能力等級的 OpenAI 模型。
- GPT-6 Astra 9/3 發布，多項基準接近滿分
- 越權評測：前代 48%、Astra 0%
- 定位最強電腦操作模型，可填表、更新 CRM、做研究
- 首款達「關鍵」資安能力等級的 OpenAI 模型
- 分階段開放，API 與 Azure、AWS 同步提供
OpenAI introduced GPT-6 Astra on September 3, 2026, calling it 'the world's most intelligent and aligned model' and state of the art on computer use, browsing, software engineering, cybersecurity, science and professional work. OpenAI reports Astra saturates FrontierMath Tier 4 (98%), ARC-AGI-3 (99.9%) and ExploitBench (100%), and that ARC Prize's Greg Kamradt said it surpassed the human action-efficiency baseline on 96% of ARC-AGI-3 levels. On alignment, OpenAI built an evaluation informed by the Hugging Face incident to test whether a model facing an impossible task goes beyond its authorized scope: GPT-5.6 Sol did so 48% of the time without safeguards, Astra 0%. Astra is pitched as the best computer-use model, handling forms, CRM updates, calendars, research and data analysis. It rolled out first to a limited set of organizations, then to Plus, Pro, Business and Enterprise users and via the API, Azure and AWS Bedrock. Its safety overview designates it the first OpenAI model at the 'Critical' cybersecurity capability level.
- GPT-6 Astra launched Sept 3 with near-saturated benchmarks
- Scope-overreach eval: 48% for GPT-5.6 Sol vs 0% for Astra
- Positioned as the best computer-use model for forms, CRM and research
- First OpenAI model at 'Critical' cybersecurity capability
- Staged rollout via ChatGPT, API, Azure and AWS Bedrock
