Recently, OpenAI officially announced that it will discontinue the preview version of the GPT-4.5 API service on July 14, 2025. This decision will have a significant impact on third-party developers using this service, although personal ChatGPT users will not be affected. Developers must migrate their applications to other models within just three months to ensure continuous business operations.

Many industry insiders and developers expressed confusion and disappointment at this news, believing that this decision may be related to computational costs and pricing strategies. As AI technology continues to advance, OpenAI needs to adjust its business model to maintain competitiveness and meet market demands. The closure of GPT-4.5 means that developers need to find new solutions to ensure their applications can continue providing services to users.

It is worth noting that when OpenAI first provided the GPT-4.5 service, its outstanding performance attracted many developers and enterprises. However, over time, how to balance high computational costs with profitability gradually became an issue that could no longer be ignored. Developers need to quickly adapt to this change and explore more cost-effective alternative models.

Although for some developers, transformation may pose a challenge, it is also an opportunity. A variety of new AI models and services are emerging in the market, allowing developers to choose according to their own needs. Meanwhile, OpenAI is actively developing more advanced AI technologies in hopes of maintaining its leading position in future competition.

OpenAI's decision will undoubtedly reshuffle the landscape of AI application development. Developers need to prepare themselves to respond to this sudden change and seek new opportunities for innovation and growth.
