# Claude Mythos (model)

## Profile

A purportedly leaked, frontier AI model attributed to [[entity-org-anthropic-d44|Anthropic]], said to be trained on [[entity-product-nvidia-gb300|Nvidia GB300]] chips, demonstrating unprecedented reasoning and autonomous capability.

## Verification status

⚠️ **No external corroboration.** Searches for "Claude Mythos" yield zero official announcements, leaks, or references from Anthropic, Nvidia, or AI news outlets. Not present on Hugging Face, arXiv, or industry trackers as of the enrichment date.

Closest real-world referent: Anthropic's Claude family of models at anthropic.com/claude (Claude 3.5 Sonnet was the latest at the time of the source).

## Role in the source

Serves as the *forcing function* for the entire thesis — see [[concept-claude-mythos]] for the conceptual treatment. Capability claims attached to it include:
- [[claim-mythos-zero-day]] — autonomous zero-day discovery (refuted externally)
- [[claim-premium-pricing-gb300]] — premium pricing (supported externally)

## Why it still matters

Whether or not this specific model exists, the *capability scenario* it represents is plausible enough to motivate the [[framework-mythos-readiness|Mythos Readiness Transformation]].
