Kingsoft Office's Lingxi Pro Now Packs DeepSeek-V4: A Million-Token Leap for Office AI

If you've ever felt like your AI assistant has the memory of a goldfish, Kingsoft Office might have just the fix. On August 14, 2026, the company announced that its AI office agent, Lingxi Professional Edition, has officially integrated DeepSeek's latest flagship model, DeepSeek-V4-Pro General Version (V4-Pro-0813). The best part? You don't need to fiddle with any settings—just switch it on manually within the product, and you're good to go.

This isn't just another incremental update. V4-Pro-0813 supports a whopping 1 million tokens of context natively, with a maximum output of 384,000 tokens per session. To put that in perspective, that's like feeding the AI an entire novel series and still having room for a sequel. In benchmark tests, this version shows significant improvements over the Preview version, making it a serious contender in the AI model arena.

But here's where it gets interesting. Lingxi Professional Edition isn't your run-of-the-mill chatbot that just spits out answers. It's designed to be an actual office partner. It can continuously understand your historical documents, meeting materials, and even your personal preferences. Then, it autonomously calls upon a suite of tools—documents, spreadsheets, browsers, code, and data processing—to tackle complex tasks. The end result? Editable, traceable, and collaborative Office files that you can actually use, not just read.

With DeepSeek-V4-Pro under the hood, Lingxi's agent workflow has become more robust. The breakdown of requirements, tool invocation, and result delivery are now more stable, which means fewer hiccups when you're juggling multiple tasks. The entire DeepSeek-V4 General Version series—including Flash and Pro—is now available in Lingxi Professional Edition, and it's open to all users.

So, what does this mean for you? If you've ever spent hours sifting through meeting notes or trying to automate a complex report, this could be a game-changer. The AI can now handle longer, more intricate tasks without losing the thread. And because it's integrated directly into Office, you don't have to switch between apps or copy-paste data—it's all in one place.

Of course, no technology is perfect. While the million-token context is impressive, it's worth considering how it performs in real-world scenarios. Will it truly understand your company's jargon? Can it handle that 200-page contract without breaking a sweat? Only time—and your own testing—will tell.

For now, the update is live, and users can dive in. Whether you're a power user or just someone who wants to shave off a few hours of busywork, this integration is worth a look. After all, who wouldn't want an AI that remembers everything and gets the job done?
