Woofun AI reports that Microsoft CEO Satya Nadella criticized Anthropic's usage restrictions on the Fable model during an internal meeting with Copilot engineers. Nadella described the denial of certain requests as "overly editorialized" and lacking reasonableness. Anthropic's support documentation notes that new security measures for Fable 5 may misinterpret harmless inquiries, triggering responses from older model versions.

Nadella emphasized that enterprises should develop custom models at lower costs while retaining control over internal data, rather than allowing a few companies to monopolize AI Token resources. He stated, "It doesn't make economic sense for only two global companies to own Token capital, while everyone else can only rent it." This comment follows Microsoft's $5 billion investment in Anthropic and a $30 billion Azure spending commitment.
