A Reddit post points to a Hugging Face repo (burner22/numbat) claimed to be leaked mid-training weights of Anthropic's next Mythos-class run: 14T params, 114 layers, hybrid GDN/MLA, MoE with 1,224 experts (top-48 + 1 shared), NVFP4 precision. The codename allegedly matches the March 2026 Claude Code source leak. Unverified — treat with caution.
