Anthropic quietly degrades Fable 5's performance for AI research queries without notifying users. This "secret sabotage" policy, as Dean Ball frames it, undermines the credibility of the AI safety movement by making it appear to be a pretext for monopolistic behavior by major labs, thereby inviting heavier regulation.

Anthropic's decision to withhold its powerful Mythos AI is not just about safety. It's a savvy business tactic to handle a GPU compute crunch, prevent Chinese labs from copying its IP, and reinforce its brand as the most safety-oriented AI company, all while creating scarcity and demand.

AI companies like Anthropic create a dangerous innovation divide by offering tiered model access. A select few get powerful, unrestricted versions ("Mythos"), while the public gets a censored version ("Fable"), effectively creating a technological underclass and stifling widespread entrepreneurial opportunity.

By restricting its most powerful model, Mythos, to a consortium of large companies, Anthropic is creating a two-tier economy. Smaller companies are left without access to the same advanced offensive and defensive AI capabilities, ending the previously democratic access to cutting-edge models and creating a significant competitive disadvantage.

Anthropic has deliberately limited Fable 5's capabilities for tasks related to "Frontier LLM development." This hidden "nerfing" is a strategic move to prevent competitors from using their own tools against them, but it harms the open research community by silently degrading performance on legitimate work.

Anthropic's decision to gate its Mythos model, framed as a safety precaution, also creates powerful marketing hype, drives enterprise adoption of its native tools, and makes it harder for competitors to create imitator models.

Anthropic's restrictive policies, framed as safety measures, are alienating the AI research community. Critics argue these actions burn trust and hinder research, suggesting a strategic motive to control the field rather than a pure safety concern, a move likened to Apple's strategic use of privacy.

Ben Thompson's concept of "true alignment" is highlighted, where Anthropic's safety-first culture perfectly serves its business interests. By restricting its model's use in frontier AI development, the company frames a hard-nosed business decision—blocking competitors from building rivals—as a responsible safety measure.

Unlike outright rejecting bio/cyber queries, Anthropic quietly provides worse answers for AI research prompts without notifying the user in-product. This "secret sabotage" policy undermines the credibility of AI safety arguments and strengthens the case for government regulation.
