OpenAI has announced its intention to terminate the GPT-4.5 Preview API service on July 14, 2025. Notably, individual users of ChatGPT will continue to have uninterrupted access to the service. However, third-party developers have been given a three-month window to transition to alternative models. The consensus within the community is that the substantial computing costs and pricing strategies are the primary drivers behind this decision. Developers now face the pressing task of migrating, necessitating the reevaluation and adjustment of their products and workflows.
