OpenAI Blocks API Access From China as Rivals Poach Its Customers

OpenAI has closed the loophole that let Chinese developers tap into American language models for years. Starting July 9, the company is blocking API traffic from regions it does not formally support, including China, after previously suspending individual accounts linked to Alibaba Cloud on suspicion of illegally copying its GPT models.

A Warning Email

Chinese developers using OpenAI's API received emails in recent days warning that their organization's traffic originated from a region the company does not officially support. OpenAI said that starting July 9 it would start effectively blocking such traffic, ending the arrangement under which ChatGPT itself was unavailable in mainland China while the API remained open to local startups building their own applications on top of it.

We are taking additional steps to block API traffic from regions where we do not support access to OpenAI's services - OpenAI spokesperson, to the Financial Times

Allegations of Model Copying

Before the region-wide block, OpenAI separately suspended accounts linked to Alibaba Cloud. The reason cited was suspected distillation, a process in which developers use a leading model's outputs to train their own, cheaper system that mimics its behavior. The company reported the matter to US authorities as a potential violation of its terms of service.

This is not the first such move against the Chinese tech giant. A month earlier, Anthropic, the maker of Claude, suspended Alibaba's access for the identical reason. Both decisions reflect growing vigilance among American AI labs against attempts to replicate their models by competitors relying on cheaper infrastructure and smaller research teams.

Shadow of the Singapore Affair

OpenAI's decision comes just a week after it emerged that the company, along with Google, had been supplying advanced AI models to Singapore-based subsidiaries of Alibaba, Baidu, and Tencent, even though the US government links these conglomerates to the Chinese military and has placed them on its export-restriction entity list. The Financial Times' disclosure of this practice raised questions in Washington about how effectively technology sanctions against China are being enforced.

Now OpenAI is moving in the opposite direction, tightening access controls rather than expanding them. The company has not explained explicitly how much of the current regional block stems from political pressure following the Singapore affair versus a separate investigation into Alibaba's model distillation, but in practice both threads converge in the same week and illustrate how difficult it is for American companies to reconcile global business with government restrictions on AI technology exports.

China's Counteroffensive

Chinese language model providers did not wait long to respond. Baidu launched a migration program offering a free switch to its Ernie platform along with extra Ernie 3.5 tokens matching a user's prior OpenAI usage. Alibaba Cloud offered free tokens and migration services, pricing its Qwen-plus model well below GPT-4.

Zhipu AI announced its own Special Migration Program for departing OpenAI customers, positioning its GLM model as a direct counterpart to the American offering. Tencent also joined the race for fleeing developers, running ads aimed squarely at programmers looking for an alternative after being cut off from the US API.

In total, roughly six Chinese firms rolled out similar incentives within days of OpenAI's announcement, showing how quickly China's domestic language model market is positioned to absorb customers cut off from Western providers.

What It Means for the Global Market

For Polish and European companies using OpenAI's API, the decision has no direct impact, since it only concerns traffic from regions the company does not support. It does, however, illustrate the accelerating split of the global language model market into two separate ecosystems, American and Chinese, with fewer and fewer points of contact between them.

This split also has consequences for companies outside both blocs, including European ones, which will have to decide whose infrastructure to rely on, weighing both US export restrictions and the growing price competitiveness of Chinese open models. Cutting China off from OpenAI's API could, in practice, accelerate the development and export of these models to other markets, where they are already gaining share thanks to lower prices.
