GPT-5编程专用版发布！独立连续编程7小时，简单任务提速10倍，VS Code就能用

Core Viewpoint - OpenAI has launched the GPT-5-Codex model, which significantly enhances programming capabilities, allowing for independent continuous programming for up to 7 hours, and introduces a new "dynamic thinking" ability that adjusts computational resources in real-time during task execution [1][4][5]. Group 1: Model Enhancements - The new GPT-5-Codex model is specifically trained for complex engineering tasks, including building complete projects from scratch, adding features, testing, debugging, and executing large-scale refactoring [8]. - In testing, GPT-5-Codex demonstrated a nearly 20% improvement in success rates for code refactoring tasks compared to the original GPT-5 [9]. - For simple tasks, GPT-5-Codex reduced output token count by 93.7%, resulting in a 10-fold speed increase in response time [11]. Group 2: Dynamic Thinking Capability - GPT-5-Codex can spend double the time reasoning, editing, and testing code for complex tasks, leading to a 102.2% increase in output token volume [12]. - The model's dynamic thinking capability allows it to adjust its computational approach during task execution, enhancing its problem-solving efficiency [4]. Group 3: Code Review and Quality Improvement - GPT-5-Codex underwent specialized training for code review, reducing the error comment rate from 13.7% to 4.4% and increasing the proportion of high-impact comments from 39.4% to 52.4% [15]. - The model can understand the true intent of pull requests (PRs) and traverse entire codebases to validate behavior through testing [15][17]. Group 4: Ecosystem and Tool Integration - OpenAI has restructured the entire Codex product ecosystem, introducing features like image input support, allowing users to input screenshots and design drafts for implementation [18]. - The updated Codex CLI now tracks progress with to-do lists and integrates tools like web search and MCP for enhanced task management [19]. - New IDE extensions bring Codex directly into editors like VS Code and Cursor, enabling seamless cloud and local task management [23]. Group 5: Market Positioning - The timing of this upgrade coincides with a decline in user subscriptions for Claude Code due to quality issues, positioning OpenAI to capture market share in AI programming [25][26].
