OpenAI has decided to block access to its API services in China starting from July 9th, 2024, amid geopolitical tensions. This move has caused Chinese developers to scramble for alternatives, with many turning to domestic AI companies like SenseTime and Baidu. These companies are offering incentives such as free tokens and migration services to attract former OpenAI users. Despite OpenAI's ban, Microsoft's Azure China continues to provide access to OpenAI's models, as Microsoft has chosen not to follow OpenAI's decision. The restriction by OpenAI is seen as a response to geopolitical tensions, though the company has not elaborated on the specific reasons for its sudden decision. This development is expected to accelerate the growth of Chinese AI models as developers seek to reduce their reliance on OpenAI.
