How could the shared AI training opt-out protocol affect Moonshot AI?
Moonshot AI may face increased data acquisition costs from new AI protocols The new shared protocol allows major Western AI operators—Google, OpenAI, Microsoft, and Anthropic—to receive binding instructions from publishers via robots.txt to prevent their content from being used for AI training. While the protocol is voluntary and only affects future content, its widespread adoption could reduce the overall volume of high-quality, accessible training data available globally. This reduction in the data pool could increase the cost and complexity for all AI developers, including Moonshot AI, who rely on massive datasets to train competitive models.

How it reaches Moonshot AI
-
On October 30, 2026, Google, OpenAI, Microsoft, and Anthropic announced joint support for a new entry in the standard robots.txt file. This protocol, called __usage_ai-training, allows publishers to block AI training across all four platforms simultaneously. Previously, publishers were required to name each crawler individually to restrict content scraping.
The full event1independent outlet -
The shared protocol, implemented by Google, OpenAI, Microsoft, and Anthropic, allows publishers to add the User-Agent: __usage_ai-training Disallow: / entry to their robots.txt. This signals to the four companies that the publisher's content should not be used to train generative AI models, thereby reducing the available training data pool. As a competitor in the AI market, Moonshot AI relies on vast datasets for model training. If the dominant Western players successfully restrict their data intake, the overall scarcity of high-quality, accessible training material could increase, raising the operational difficulty and cost for Moonshot AI to develop competitive models.

The facts so far
As reported. Each one links to where it comes from.
- The protocol allows publishers to block AI training across Google, OpenAI, Microsoft, and Anthropic at once using a single entry in robots.txt.techtimes.com
- The token, __usage_ai-training, is a purpose-based namespace, specifying why a crawler may not visit, rather than naming a specific crawler.techtimes.com
- The standard is voluntary, and a company that ignores the token faces no direct sanction from the protocol itself.techtimes.com
- Anthropic has already begun implementing support for the token, making it the first of the four companies to go live.techtimes.com
Why it matters
The availability of high-quality training data is a fundamental determinant of success in the AI race. For Moonshot AI, like all AI developers, access to massive, diverse, and clean datasets is critical for achieving state-of-the-art performance. If the dominant Western players successfully restrict their data intake, it could create a global data bottleneck, making it harder and more expensive for all competitors to maintain pace.
This development highlights the tension between intellectual property rights and the advancement of AI. While the protocol is designed to protect publishers' rights, its market-wide effect could inadvertently raise the barrier to entry for smaller or non-Western AI firms, potentially concentrating AI power among those who can afford to acquire alternative, non-web-scraped data.
What we don't know yet
- Will the __usage_ai-training token eventually gain mandatory legal authority, particularly in jurisdictions outside the EU?
- Will Moonshot AI be able to secure alternative, non-web-scraped data sources to mitigate the impact of the protocol?
