TAC-CoT: Interleaved Latent and Explicit Tokens for Agentic Reasoning
November 1, 2026
TAC-CoT replaces explicit reasoning traces with compact latent tokens, using textual tokens only for tool calls and observations. This reduces generation overhead while maintaining the necessary communication interface for agentic tool-use.
