Architecture Verified, Mythology Intact: Running OpenMythos on a Strix Halo
Kyegomez published OpenMythos as a speculative, open-source reconstruction of Claude Mythos. I ran the 1B variant on a Strix Halo (Radeon 8060S, ROCm) to test what an open reconstruction of a frontier model can and cannot teach you. The architecture's internal claims check out: rho(A) at init is exactly e^-1, the spectral-radius stability constraint prevents the failure mode it's designed to prevent, and hidden states blow up exactly as the LTI analysis predicts. What it does not teach you: anything about Claude Mythos.
