DeepSeek V3.1 Terminus

A targeted refinement of the V3.1 architecture engineered to solve language consistency and multi-agent coordination issues. Built on the 671B parameter MoE structure, the Terminus patch eliminates random character drift and cross-language mixing to deliver stable textual formatting. It optimizes the model’s active 37B parameter routing to enhance the performance of advanced Code Agents and Search Agents. Operating via dual Chat and Reasoner modes, it handles structured tool calling and long-context documents effortlessly up to a 164K window. This makes the model an exceptional, production-grade engine for complex software engineering pipelines, real-time web research agents, and automated corporate knowledge curation without output formatting errors.
