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 Insights - OpenAI has launched the GPT-5-Codex specialized model, which supports independent continuous programming for up to 7 hours [1][2] - The new model features a dynamic routing mechanism that allows real-time adjustments during task execution, enhancing its ability to handle complex tasks [2][5] - GPT-5-Codex has shown a nearly 20% improvement in success rates for code refactoring tasks compared to the original GPT-5 [5] Performance Enhancements - The model exhibits "true dynamic thinking" capabilities, significantly reducing output token counts for simple tasks by 93.7%, resulting in a 10-fold speed increase [8] - For complex tasks, it takes twice as long for reasoning, editing, and testing, with output token counts increasing by 102.2% [8] - The error comment rate during code review has decreased from 13.7% to 4.4%, while the proportion of high-impact comments has risen from 39.4% to 52.4% [11] Ecosystem Upgrades - OpenAI has restructured the entire Codex product system, introducing features like image input support and a task tracking to-do list for complex tasks [14] - The new IDE extensions integrate Codex into popular editors like VS Code and Cursor, allowing seamless cloud and local task management [14] - Performance improvements in cloud infrastructure have reduced median completion times for tasks by 90% [15] Market Positioning - The timing of this upgrade coincides with a decline in user subscriptions for Claude Code, positioning OpenAI to capture market share in AI programming [16] - There is a suggestion for Microsoft to upgrade its Copilot, indicating competitive pressures in the AI programming space [18]
