A theoretical reconstruction of the Claude Mythos architecture, built from first principles using the available research literature.
OpenMythos **Disclaimer:** OpenMythos is an independent, community-driven theoretical reconstruction based solely on publicly available research and speculation. It is not affiliated with, endorsed by, or connected to Anthropic or any of their proprietary systems. OpenMythos is an open-source, theoretical implementation of the Claude Mythos model. It implements a Recurrent-Depth Transformer (RDT) with three stages: **Prelude** (transformer blocks), a looped **Recurrent Block** (up to max_loop_iters), and a final **Coda**. Attention is switchable between MLA and GQA, and the feed-forward uses a sparse MoE with routed and shared experts ideal for exploring compute-adaptive, depth-variable reasoning. ## Installation To enable Flash Attention 2 in GQAttention (requires CUDA and build tools): #
