WPS AI's Lingxi Pro Gets DeepSeek-V4: A Million-Token Leap for Office Work

If you've ever wished your office software could just get your work style—remembering your past projects, understanding your meeting notes, and then actually doing the heavy lifting—you're not alone. That's exactly the promise Kingsoft Office is making with the latest update to its AI assistant, Lingxi Professional Edition.

On August 14, 2026, the company announced that Lingxi Pro has officially integrated DeepSeek's newest flagship model, the V4-Pro-0813. The best part? You don't need to fiddle with any settings. Just switch to it manually within the product, and you're ready to roll.

A Million Tokens of Context: What That Actually Means

For the uninitiated, the headline feature here is the context window—a whopping 1 million tokens. That's roughly equivalent to reading three volumes of 'War and Peace' in one go. In practical terms, it means the AI can hold an enormous amount of information in its 'working memory' at once. It can digest your entire document library, cross-reference past emails, and still have room to generate a response that's up to 384,000 tokens long in a single session.

That's a game-changer for complex office work. Instead of feeding the AI snippets of information piecemeal, you can throw an entire project's worth of materials at it and ask for a comprehensive analysis, a draft proposal, or a detailed report—all in one go.

More Than Just a Chatbot

Here's where Lingxi Pro sets itself apart from the average AI chatbot. It's not just about having a conversation; it's about getting work done. The system is designed to continuously learn from your historical documents, meeting materials, and even your personal preferences. It then autonomously calls upon a suite of tools—think documents, spreadsheets, browsers, code, and data processing—to tackle complex tasks from start to finish.

The end result? Native Office files that are fully editable, traceable, and ready for collaboration. No more copy-pasting from a chat window into a Word doc. The AI hands you a polished deliverable, complete with the ability to see how it got there.

The DeepSeek-V4 Integration: A Boost in Stability

With the integration of DeepSeek-V4-Pro, the entire workflow of Lingxi Pro—from breaking down your requirements to invoking the right tools and delivering the final output—has become more robust. The company says this significantly enhances the stability of automated processing in complex office scenarios. In other words, fewer hiccups, fewer errors, and a smoother ride when you're juggling multiple tasks.

The DeepSeek-V4 General Version series, which includes both the Flash and Pro versions, is now fully available in Lingxi Professional Edition. And it's open to all users right now.

What This Means for You

If you're someone who spends hours in spreadsheets, drafting reports, or coordinating projects, this update could genuinely change how you work. Imagine asking your AI to 'prepare the quarterly financial summary based on last year's data and the recent sales meeting notes,' and having it come back with a formatted spreadsheet and a draft presentation—all without you lifting a finger.

Of course, it's still early days for AI-powered office assistants, and there will be kinks to iron out. But with a million-token context and a more stable execution engine, Lingxi Pro is positioning itself as a serious contender in the AI office space.

So, if you're curious, it might be worth giving it a spin. After all, the future of office work might just be a conversation away.
