OpenMythos: 22‑Year‑Old Recreates Claude Mythos with Recurrent Depth Transformers

A 22‑year‑old developer reverse‑engineered Anthropic’s confidential Claude Mythos, releasing the OpenMythos project that employs a Recurrent Depth Transformer looping a single weight set up to 16 times, matching a 1.3 B‑parameter transformer’s performance with only 770 M parameters while enabling deeper inference and solving gradient instability.

How a 22‑Year‑Old Reversed‑Engineered Mythos into OpenMythos Using MoE and DeepSeek‑Inspired Attention

OpenMythos re‑creates the Claude Mythos architecture as a Recurrent‑Depth Transformer with MoE routing, achieving comparable performance to larger Transformers while using roughly half the parameters, and demonstrates systematic generalization and depth extrapolation through looped inference in latent space.

OpenMythos: Rebuilding Claude Mythos with Recursive Transformers and MoE

OpenMythos is an open‑source PyTorch reimplementation of Anthropic's Claude Mythos that uses a mixed‑expert routed recurrent Transformer, introduces Recursive Depth Transformers, Multi‑Latent Attention, and several stability mechanisms, and demonstrates parameter‑efficient scaling backed by empirical studies.
