OpenMythos: Open-Source Hypothetical Claude Mythos Architecture
Kye Gomez, creator of the Swarms multi-agent framework, has released OpenMythos — an open-source ~770M parameter implementation of a hypothetical Claude Mythos-style architecture derived entirely from public papers. The proposed architecture is a Recurrent-Depth Transformer with MoE routing: a standard Prelude block initializes hidden state; a shared Recurrent Block is applied N times with per-pass LoRA adapters for depth-specific variation; a Coda block produces final logits. This enables latent-space reasoning across recurrent steps before token emission — controllable compute depth as a budget parameter. The repo is gaining thousands of GitHub stars and developers are already scaling the architecture.
Why It Matters
OpenMythos gives the research community an open platform to test and scale a latent-recurrence reasoning architecture — regardless of whether it approximates Anthropic's actual implementation.
