Anthropic launches safe Claude Fable 5 with restrictions
Anthropic has released two new AI models: Claude Fable 5 for the general public and Claude Mythos 5 for a restricted circle of trusted partners. Both models share the same technical foundation but differ significantly in usage restrictions. Fable 5 is the deliberately restricted 'safe' variant, using classifiers to automatically switch risky queries to the weaker Claude Opus 4.8 model. It excels in software development, knowledge work, image processing, biosciences, and genomics. Pricing is set at $10 per million input tokens and $50 per million output tokens. The release has drawn criticism from research community for secretly throttling performance on ML research queries.
Anthropic, a major AI platform, releases new flagship models with advanced capabilities and safety restrictions, significantly impacting the AI and AdTech ecosystem.
