Community open-sources theoretical reconstruction of Claude Mythos
Shruti_0810 · x · 2026-08-27
A community-driven project called OpenMythos has been open-sourced, providing a theoretical reconstruction of Anthropic's Claude Mythos architecture. Built as a Recurrent-Depth Transformer, it features:
- Recurrent reasoning blocks
- Switchable MLA / GQA attention
- Sparse MoE feed-forward layers
- Configurable reasoning depth
- PyTorch implementation
The author clarifies this is not an official Anthropic release but a community implementation based on public research and speculation. It serves as a valuable resource for exploring how such advanced architectures might function under the hood.
