DeepSeek described V3.1 as the company’s “first step towards the agent era”, laying the groundwork to support software that helps users automate specific tasks.
The Hangzhou-based start-up said the updated model featured improved coding and search capabilities, as well as enhanced language consistency.
Before the update, users had shared screenshots showing instances where DeepSeek’s namesake chatbot produced responses containing illegible symbols and occasionally switched between Chinese and English without being prompted.
According to DeepSeek’s self-reported scores, V3.1-Terminus showed slight improvements on several popular benchmarks.
