The volume of the gray market for access to foreign artificial intelligence through Chinese proxies reached 150 million rubles per month. At the end of 2025, there were almost no intermediaries in this service, but now their number has increased to about 50. This data is provided by the GPTunneL aggregation platform. Advanced platforms - in particular, ChatGPT, Cloud and Codex - are officially blocked in Russia, so intermediaries build an infrastructure based on farms of foreign accounts and subscribers. High demand from the business sector is combined with a significant price gap: offers from unofficial suppliers are cheaper than the official rates. The legal segment of aggregators is estimated at 700 million rubles every month. The price difference between legal and gray suppliers increases the tax burden. Official Russian services are forced to include VAT at a rate of 22%. Another reason for the requirement for intermediaries is the active blocking of Russian accounts by Anthropic. But there are security and fraud risks. Under the guise of an expensive western neural network, the customer may get answers from cheaper Chinese analogues - Kwon or Minimax. Requests and responses from corporate clients can be intercepted without permission and used to train third-party neural networks. The developers of the original models improve the detection methods and can disable proxy broker accounts at any time.
