Meet OpenMythos: An Open-Source PyTorch Reconstruction of Claude Mythos Where 770M Parameters Match a 1.3B Transformer
770M parameters matching 1.3B performance. Here's what researchers reverse-engineered about Claude's secret architecture.
Why it matters
Open-source reconstruction of Anthropic's undisclosed Claude Mythos architecture reveals potential efficiency gains through theoretical first-principles modeling. Signals growing research community focus on understanding closed-model training approaches.

Publisher excerpt: Anthropic has never published a technical paper on Claude Mythos. That has not stopped the research community from theorizing. A new open-source project called OpenMythos, released on GitHub by Kye Gomez, attempts something ambitious: a first-principles theoretical reconstruction of what the Claude…
