DEEPSEEK-V3.1-TERMINUS LAUNCHES WITH IMPROVED AGENTIC TOOL USE AND REDUCED LANGUAGE MIXING ERRORS

Summary from the TLDR AI newsletter

DeepSeek released V3.1-Terminus, which strengthens its Code Agent and Search Agent and addresses users' feedback about Chinese/English mix-ups. The model shows benchmark gains in agentic tool tasks (BrowseComp, SWE Verified, etc.) and offers both “chat” and “reasoner” modes for different use cases. Terminus remains open-weight under an MIT license, making it viable for customization and deployment both via API and local environments.
