Anthropic Unveils New AI Models 'Mythos 5' and 'Fable 5'

Anthropic has entered the AI model performance race with the release of 'Claude Mythos 5' and 'Claude Fable 5.' 'Fable' means fable, and 'Mythos' means myth or saga, with Anthropic clarifying its AI model classification system through these two models. Among the new models, 'Fable' uses the same base model as 'Mythos' but differs in its enhanced safety features that restrict responses to harmful queries. Anthropic's expansion of its 'Claude' series, following 'Haiku,' 'Sonnet,' and 'Opus,' with 'Fable' and 'Mythos' reflects the recent technological trend of imbuing AI model naming with meaning and identity.

OpenAI revealed that the name 'ChatGPT' emerged from an internal hackathon. AI models that attract hundreds of millions of users are perceived as digital characters influencing user behavior and expectations. Consulting firm The Naminist analyzes that the naming strategy for AI products defines the relationship between users and technology.

Current AI naming patterns are categorized into human names, systems, and abstractions, which influence user expectations. Personalized model names make even somewhat ambiguous answers more acceptable, whereas system names can lead to more sensitive reactions to AI hallucinations. The interpretations surrounding Anthropic's 'Mythos' and 'Fable' also illustrate a facet of the phenomenon where AI models are perceived as brands beyond mere technology.
