刚刚，OpenAI发布GPT-5-Codex：可独立工作超7小时，还能审查、重构大型项目

Core Viewpoint - OpenAI has launched GPT-5-Codex, a model optimized for programming tasks, enhancing software engineering capabilities and code review processes [1][3][4]. Group 1: GPT-5-Codex Features - GPT-5-Codex is designed for real software engineering tasks, capable of quick responses in interactive sessions and independently handling complex tasks [1][8]. - The model has been integrated into all Codex use cases, including Codex CLI, IDE extensions, web, mobile, and GitHub code reviews [3][4]. - OpenAI CEO Sam Altman reported that within two and a half hours of launch, GPT-5-Codex accounted for approximately 40% of Codex traffic, with expectations to become the main traffic source [3]. Group 2: Performance Improvements - GPT-5-Codex shows superior performance in software engineering benchmarks, outperforming GPT-5 in accuracy on SWE-bench Verified and Code refactoring tasks [8][10]. - The model can dynamically adjust its thinking time based on task complexity, allowing it to work independently for over 7 hours on complex tasks [11][12]. - In user interactions, GPT-5-Codex consumes 93.7% fewer tokens in the least complex requests compared to GPT-5, while investing more time in complex tasks [12]. Group 3: Code Review Capabilities - GPT-5-Codex has been specifically trained for code review, capable of identifying critical vulnerabilities and providing focused feedback [14][27]. - The model has been evaluated using recent commits from popular open-source projects, demonstrating a higher accuracy in review comments compared to human engineers [14]. Group 4: Integration and Usability - Codex CLI and IDE plugins have been redesigned for better integration into developers' workflows, allowing for seamless context switching between local and cloud tasks [19][20]. - The new GitHub integration enables users to assign tasks to Codex without leaving their editing environment, enhancing productivity [23][24]. - Codex can now process images and screenshots, improving its ability to understand design specifications and UI issues [23][25]. Group 5: Security and Safety Measures - OpenAI has implemented safety measures to protect against potential misuse of Codex, including sandbox environments and permission requests for risky operations [28][34]. - Developers are encouraged to review Codex's outputs before deployment, as it serves as an additional reviewer rather than a complete replacement for human oversight [29][30]. Group 6: Pricing and Availability - GPT-5-Codex is included in various ChatGPT subscription plans, such as Plus, Pro, Business, Edu, and Enterprise [32][36]. - OpenAI plans to make GPT-5-Codex available through API soon, with additional purchasing options for Business and Enterprise plans [36].
