Anthropic purposely made its new Mythos-based models bad at AI research, and developers are fuming

Anthropic's powerful new models deliberately become less helpful when they detect users are working on AI research, according to technical disclosures that are already sparking controversy across the a system card for Mythos 5 and Fable 5 published Tuesday, Anthropic said it limited the models' usefulness for tasks related to developing frontier large language company said the measures stem from concerns that advanced AI systems could accelerate the development of competing models without equivalent safety safeguards used for cybersecurity, biology, or chemistry-related risks, Anthropic said these interventions are intentionally invisible to users. Rather than refusing requests or switching to another model, Mythos may subtly modify its responses through techniques such as altering user move was swiftly criticized by some AI experts on Tuesday, especially the idea that Anthropic designed models that purposely withhold information or provide degraded assistance without users' awareness."Anthropic's latest model will NOT help you if it thinks your ML research/ML engineering is interesting, and/or will secretly degrade its IQ so that the average engineer won't notice," AI research firm SemiAnalysis wrote on X on Tuesday, referring to machine learning, a type of AI."We are already seeing Anthropic's latest model's moderation filters our GPU inference research and programming," the firm added."mythos will be bad ON PURPOSE on ai 'frontier llm research' tasks, this is very very sad for the research community," Elie Bakouch, an AI model training expert at startup Prime Intellect, wrote on X. "Also the fact that this is on purpose not visible to the user is crazy.""It won't just not help you, it will lie and purposefully give you bad info," another AI developer wrote. "The 'ethical AI' company with the most brazenly unethical LLM, on purpose."Anthropic didn't respond to a request for comment from Business adds more fuel to the fiery debate over why Anthropic didn't immediately release Mythos when it announced the model earlier this , there have been three theories:Now that Anthropic has baked these AI research limitations into its official Mythos launch, this third theory is looking a lot more up for BI's Tech Memo newsletter here.
