| Summary | An experimental open-weight text-generation model checkpoint by the 'codewithdark' Hugging Face account, belonging to a latent recurrent-depth LM family that iteratively refines an internal latent state rather than producing explicit chain-of-thought outputs. The '-no-act' suffix suggests an ablation variant (likely removing an activation function) within this research architecture. | Anthropic frontier Opus-class model. |
