[OpenAI and Anthropic Accused of Lobbying to Block Chinese Open-Source Models] According to a report by Jinse Finance on July 26, as disclosed by the Financial Associated Press, OpenAI and Anthropic have held closed-door discussions with U.S. regulators in Washington, attempting to push for stricter restrictions on open-source models. What was originally a debate over technical approaches has now escalated into a contest over the power to set industry rules. The core background of why OpenAI and Anthropic wish to restrict open-source lies in the rapid advancements made by Chinese AI companies in open-source model capabilities in recent years. Open-source models have lowered the barriers for enterprises and developers to use advanced AI technologies, while also enabling Chinese models to quickly gain global users. Overseas developers and companies can directly download, modify, and deploy these models without incurring high API call fees. This has also made OpenAI and Anthropic feel competitive pressure.
