In August 2025, OpenAI made a significant announcement regarding the release of GPT-5, with its primary enhancement being the GPT-5-Codex model. This innovative model is capable of dynamically allocating 'thinking' time, accommodating programming tasks that range in processing duration from a mere few seconds to an extensive seven hours. In AI agent programming benchmark tests, it has showcased exceptional performance. GPT-5 seamlessly integrates four key modules: Codex (dedicated to code generation), Operator (responsible for task automation), Deep Research (for in-depth research endeavors), and Memory (providing dynamic memory capabilities), thereby enabling full-modality interaction. It significantly boosts programming efficiency by threefold, enhances code refactoring efficiency by 30%, and streamlines full-cycle development tasks, reducing the time required from several days to a mere 30 minutes. Additionally, GPT-5 has demonstrated notable advancements across various domains, including mathematics, science, finance, and law. Compared to its predecessor, it has achieved a 40%-45% reduction in hallucination rates. Furthermore, OpenAI offers both free and tiered subscription services to cater to a wide range of user needs.
