DeepSeek vs Manus: Which Chinese LLM Is Leading the Race in 2025

What if we let two powerful Chinese AI models face off in a real showdown?

Well, that’s exactly what this blog is about.
A full-on comparison: Manus vs Deepseek.

On one side, we have Deepseek AI, the model that shook the US stock market upon launch.

On the other hand, there’s Manus, the AI agent that’s rumored to have outperformed 

Deepseek and is now making waves in the AI space.

But are they really that great, or is it all just a clever media buzz?

In this blog, we’ll dive into what makes both of them unique, explore how Manus stands out, and help you decide:

• Should you go with Deepseek
• Or is it time to switch to Manus AI agent?

さあ始めましょう。

DeepSeek AI

Imagine an AI model as powerful as ChatGPT-4, but built in just 2 months, and at a fraction of the cost.

That’s Deepseek AI for you.

Launched by Chinese startup Deepseek, founded in 2023 by Liang Wenfeng, this AI model came into the spotlight on January 10, 2025, when they released Deepseek R1—a model that quickly turned heads across the globe.

なぜ？
Because it was built for just $5.6 million, while ChatGPT-4 reportedly cost anywhere between $40–$80 million to develop.

And the ripple effects were massive.

On January 27, 2025, just weeks after Deepseek’s launch, Nvidia’s stock crashed, dropping to $177 and wiping out nearly $600 billion in market value. 

The U.S. stock market as a whole almost lost $1 trillion in a single day.

All of this was triggered by Deepseek’s bold move. 

If you’re curious about how Deepseek’s reasoning AI shook the global market, this detailed breakdown explains the $1 trillion disruption.

What makes Deepseek AI even more remarkable is how cheap it is—not just to build, but also to run.

Thanks to smart engineering, Deepseek cracked the code to cut GPU costs, making its model up to 10x cheaper than OpenAI’s in real-time use.

Their commercial API is also significantly more affordable—again, nearly 10x less than OpenAI’s pricing.

That means startups, developers, and mid-tier businesses can now access advanced AI without breaking the bank. 

Lower costs = wider adoption of AI = a global tech shift.

This breakdown explains how that impacted the global market.

The best part is that Deepseek is an open-source model.

Unlike ChatGPT-4, you can download, modify, and run Deepseek AI on your own hardware if you’ve got the setup. 

This gives developers and companies more control and freedom to innovate.

Now let’s talk about Manus, the model being hailed as a 「second Deepseek moment”.

Manus is a next-gen AI agent that doesn’t just chat, it does things for you.

If you want to know more on AI agents, this blog covers 6 AI agents that are so good they feel illegal to use.

Yup, it gets work done on your behalf.

Manus can autonomously perform complex tasks, way beyond basic Q&A.

It’s a mix of:

• Perplexity’s deep research
• ChatGPT’s operator mode (which usually costs $200/month)
• Claude’s creativity and coding powers
• Plus, a builder that can create full websites

…all packed into one powerful tool.

With Manus, you get access to the best features from top AI models, without juggling multiple tools.

Here’s what it can do:

• Research deeply on any topic
• Break your goal into small tasks, and actually do them
• Create websites for you
• Write content, analyze info, and even code when needed

In short, the Manus AI agent is like having your own digital assistant that thinks, plans, and executes — all on its own.

If you’re curious about where it stands in the bigger picture, here’s a great deep dive on how Deepseek and other AIs like Manus are playing different games.

Manus vs Deepseek: Comparing the AI models 

Both these AI models are making serious noise in 2025.

But what makes them different? Which one’s right for you?

Let’s break it down in the simplest way possible, no fluff, just real talk.

1. Architecture and How They Work:

Deepseek is your classic AI chatbot. 

It’s built on a single large language model (LLM), like ChatGPT. 

It’s made to:

• Talk smart
• Answer fast
• Be super responsive. 

Basically, it’s like a really smart friend who always has a reply ready.

Manus AI, on the other hand, is built as a multi-agent system.

This means it’s not just one brain, it’s multiple smaller brains working together to complete tasks.

It doesn’t just reply. 

それ：

• 考える
• Plans
• Breaks the job into steps
• Execute it—without needing constant input from you.
  

2. Features and Use Cases:

Deepseek AI:

• Fast, human-like conversations
• Strong in creative writing
• Great for code generation and technical questions
• Works well for brainstorming, explanations, summaries
  

Manus AI:

• Task planner + executor
• Can build websites, do deep research, and run multi-step workflows
• More like a digital employee than a chatbot
• Can manage entire projects from scratch with just a prompt
  

3. Performance & Speed:

Deepseek is quick. Replies come in seconds.

Manus, though powerful, can be slow. Sometimes it takes minutes or even hours, depending on how complex the task is.

次のように考えてみましょう。

• Deepseek = Fast thinker
• Manus = Slow but smart worker
  

If you want speed, go with Deepseek.
If you want depth and completion, Manus is your pick.

4. Cost and Accessibility:

Both are open source, which is amazing.

Deepseek, however, has some international restrictions, especially outside China. 

So, depending on where you are, you might face trouble running or accessing it.

Manus is currently more freely available and works well globally, especially for developers and builders who have the right setup.

To wrap it up:

• Use Deepseek if you need an AI buddy to help you think, write, and code fast and smoothly.
• Use Manus AI if you want a serious digital assistant that can actually do things for you with little follow-up.
  

Both are powerful. Just depends on whether you want an AI to talk smart or to work smart.

What does the internet have to say about these?

Alright, let’s be real.

Both Manus AI and Deepseek AI are getting major attention in the AI world lately.

One’s being hyped as “the next Deepseek moment,” and the other is already known for being a fast, creative, consistent assistant.

Here’s what users are saying online:

 “Manus crashed more than it worked. 

Deepseek is just more reliable. I still prefer it for coding and general use.”

“Deepseek is like a reliable office assistant. Manus feels like a genius intern—great when it works, but might ghost you mid-task.”

 “Manus found $1000 in billing errors in my phone bills. Then it wrote me a whole call script to get my refund back. That blew my mind!”

“I asked Manus to list restaurants in my area. It started the job… but stopped halfway. Used up all my credits for 4 entries.”

So yeah… people are split.

Some love Manus for its power.
Some trust Deepseek for being stable.

これ comparison piece even suggests that Deepseek might give GPT-4 and Claude 3 a run for their money in 2025.

Final Verdict: Who Wins the Showdown?

If we go by pure performance + everyday reliability, the winner is: Deepseek AI

理由は次のとおりです。

• Works consistently
• Faster response times

Both are powerful.
But as of June 2025, the internet + benchmarks say: Deepseek wins—for now.

Still can’t decide? Here’s a great breakdown of Deepseek’s under-the-hood capabilities that might just help you out.

Conclusion: So, Who Takes the Crown in the Manus vs Deepseek Showdown?

Both Deepseek and Manus have their unique approach to AI. 

One thrives on speed and conversational flow, while the other shines in execution and automation.

But if we talk about the current Manus vs Deepseek face-off? ディープシーク takes the lead.

Before writing this blog, I gave both of them the same prompt: “Write a blog comparing Deepseek and Manus.”

• ディープシーク delivered a well-structured blog with proper tone, clarity, and flow.
• の Manus AI agent, on the other hand, sent back a plain file—just raw facts with zero tone or storytelling. 

It felt like a data dump rather than something usable right away.

So, based on personal testing too, ディープシーク wins—for now.

Whether it’s speed, accuracy, creative writing, or code support, ディープシーク holds up impressively well.

Still, don’t just take my word for it—try both. 

Your use case might favor one over the other.

Just remember:

• Deepseek is a smart chatbot built for fluid interactions.
• Manus AI agent is more of a digital worker—less talk, more action.
