Kingsoft Office's Lingxi Now Runs DeepSeek-V4 with Million-Token Context

If you've ever wished your office software could just get your workflow, Kingsoft Office might have just taken a big step in that direction. On August 14, 2026, the company announced that its AI-powered assistant, Lingxi Professional Edition, has officially integrated DeepSeek's latest flagship model, the V4-Pro General Version (V4-Pro-0813). The best part? You don't need to fiddle with any settings—just manually switch within the product, and you're ready to go.

This isn't just another incremental update. The V4-Pro model brings a whopping 1 million tokens of native context support, with a maximum output of 384,000 tokens per session. To put that in perspective, that's like feeding it an entire novel series and asking for a detailed analysis—it can handle it without breaking a sweat. Benchmark tests show significant improvements over the Preview version, making it a serious contender in the AI model arena.

But what does this mean for you, the everyday user? Lingxi Professional Edition isn't your typical chatbot that just spits out answers. It's designed to be an intelligent agent that can understand your historical documents, meeting materials, and even your personal preferences. It can autonomously call upon various tools—documents, spreadsheets, browsers, code, and data processing—to tackle complex tasks from start to finish. The end result? Native Office files that are editable, traceable, and ready for collaboration.

With the integration of DeepSeek-V4-Pro, the agent's execution workflow has become more robust. It's better at breaking down requirements, invoking the right tools, and delivering results that actually make sense. This translates to more stable and reliable automated processing, especially in those messy, multi-step office scenarios that usually make you want to pull your hair out.

The DeepSeek-V4 General Version series is now fully available in Lingxi Professional Edition, including both the Flash and Pro versions. That means all users can access this powerful capability right away. So, if you've been looking for an AI assistant that can truly handle the heavy lifting, this might be worth a try.
