DeepSeek vs Qwen vs Kimi vs GLM: Which Chinese API Wins in 2025?

DeepSeek vs Qwen vs Kimi vs GLM: Which Chinese API Wins in 2025?

I almost didn't write this article.

When I started exploring AI APIs during my bootcamp, I kept reaching for the same handful of Western models everyone talks about. Then one of my instructors casually said, "Have you looked at what China is doing?" I had no idea what I was about to find.

Blew my mind is an understatement. I went down a rabbit hole of Chinese AI models I had never heard of, and what I discovered kind of changed how I think about API pricing forever. Let me walk you through the four families that ate up my entire weekend: DeepSeek, Qwen, Kimi, and GLM.

The Whole Reason I Cared Enough to Compare Them

Here's the thing I had no idea about before all this: Chinese AI labs aren't just catching up anymore. In some areas they're ahead. And the pricing? I was shocked when I saw some of these numbers. We're talking fractions of a cent per million tokens compared to what I was paying elsewhere.

But here's the catch — picking one randomly is a disaster. Each family has a totally different vibe. One is a speed demon. One is a reasoning beast. One has like 47 different models because they love shipping new ones every other week. I needed real test data, not just vibes from Twitter.

So I spent a solid week poking all four through Global API's unified endpoint (https://global-apis.com/v1) which lets you hit all these models with the same OpenAI-style code. Absolute lifesaver for a bootcamp grad who doesn't have time to learn four different SDKs.

Here's My Cheat Sheet Before We Dive In

Let me give you the bird's-eye view, because I know comparison tables saved me during every project review at bootcamp.

Family Developer Price Range Budget Pick Top Pick
DeepSeek DeepSeek (幻方) $0.25-$2.50/M V4 Flash @ $0.25/M V4 Flash @ $0.25/M
Qwen Alibaba (阿里) $0.01-$3.20/M Qwen3-8B @ $0.01/M Qwen3-32B @ $0.28/M
Kimi Moonshot AI (月之暗面) $3.00-$3.50/M N/A K2.5 @ $3.00/M
GLM Zhipu AI (智谱) $0.01-$1.92/M GLM-4-9B @ $0.01/M GLM-5 @ $1.92/M

Quick ratings across the things I actually care about:

Thing I Care About DeepSeek Qwen Kimi GLM
Code generation ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐
Chinese language ⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐
English language ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐
Reasoning chops ⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐
Raw speed ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐ ⭐⭐⭐⭐
Vision/image stuff Limited

All four give you up to 128K context, and all four speak OpenAI's API dialect, so you can plug them into existing code with almost zero changes. I cannot stress how much that mattered to me.

DeepSeek: The One I Keep Reaching For

I'm gonna start with DeepSeek because it's basically become my default for everything.

Honestly? When I first tried DeepSeek V4 Flash, I had no idea an API this cheap could be this competent. We're talking $0.25 per million output tokens. Let that sink in. For the kind of quality it produces, that price felt illegal.

The whole DeepSeek lineup I tested:

Model Output $/M What I Used It For
V4 Flash $0.25 Daily grind, coding, blog drafts
V3.2 $0.38 When I want the newest architecture
V4 Pro $0.78 Production stuff that can't break
R1 (Reasoner) $2.50 When I'm stuck on math or logic
Coder $0.25 Hackathon code sessions

What won me over:

  • The price-to-quality ratio genuinely blew my mind. V4 Flash holds its own against stuff costing 5-10x more.
  • Code generation is chef's kiss. I ran my usual HumanEval-style drills and it kept cleaning up.
  • Speed is wild. I clocked around 60 tokens per second on V4 Flash, which made my API calls feel snappy in a way I wasn't expecting from a cheaper model.
  • English output is solid. Didn't feel weird or stilted like I worried it might.
  • Open-weight roots mean there's actual documentation out there when I get curious.

Where it stumbled:

  • Vision is basically a no-go. If I need image understanding, I'm not picking DeepSeek.
  • Chinese-language tasks aren't its strongest suit — GLM and Kimi had it beat in my Mandarin translation tests.
  • Fewer size options than Qwen. Sometimes I want a middle-ground model that DeepSeek just doesn't have.

Here's the actual snippet I used during testing, stripped down to the bones:

from openai import OpenAI

client = OpenAI(
    api_key="ga_xxxxxxxxxxxx",
    base_url="https://global-apis.com/v1"
)

response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Explain quantum computing in 100 words"}]
)
print(response.choices[0].message.content)
Enter fullscreen mode Exit fullscreen mode

Three lines of setup and I'm off to the races. This is the life I signed up for when I left my marketing job to do a bootcamp, not wrestling with auth tokens for an hour.

Qwen: The One With Endless Variants

If DeepSeek is a scalpel, Qwen is a Swiss Army knife with 47 attachments. Maybe more. They keep shipping.

The lineup I tested covered everything from absurdly cheap to "this better be worth it":

Model Output $/M Best For
Qwen3-8B $0.01 Tiniest tasks where I barely need any brain
Qwen3-32B $0.28 My everyday default for Qwen
Qwen3-Coder-30B $0.35 Coding-specific jobs
Qwen3-VL-32B $0.52 Anything image-related
Qwen3-Omni-30B $0.52 Audio, video, image combo stuff
Qwen3.5-397B $2.34 When enterprise reasoning matters

The starting price of $0.01/M legitimately floored me. I had no idea you could get usable completions at that price. Alibaba (the parent company) is clearly subsidizing the bottom of the stack, but I don't care about their business model — I care that my weekend project costs me pennies to run.

What I loved:

  • The range is unmatched. From $0.01 to $3.20 per million tokens, I can pick a Qwen for literally any budget.
  • Vision models are legit. The Qwen3-VL series handled image prompts better than I expected for the price.
  • Omni-modal options let me throw audio + video + images into a single call.
  • Alibaba's enterprise infrastructure means I never hit weird rate limits.
  • They ship new versions constantly. Qwen3.5 and Qwen3.6 drops kept showing up in my news feed.

What bugged me:

  • The naming is chaotic. Trying to remember if I want Qwen3-32B or Qwen3.5-32B or Qwen3.6-35B gave me a headache.
  • English is good, not DeepSeek-tier great. I noticed it most on creative writing tasks.
  • Some middle-tier models feel pricey. Qwen3.6-35B at $1/M didn't always justify the bump over the cheaper 32B.

For my general-purpose tests, I went with Qwen3-32B and here's the kind of call:

response = client.chat.completions.create(
    model="Qwen/Qwen3-32B",
    messages=[{"role": "user", "content": "Write a Python function to merge two sorted lists"}]
)
print(response.choices[0].message.content)
Enter fullscreen mode Exit fullscreen mode

Same client setup, same pattern, different model string. That's the magic of going through a unified endpoint.

Kimi: The Brainy One That Costs Real Money

Okay so Kimi is the odd one out in pricing. I had no idea until I ran the numbers that every Kimi model sits in the $3.00-$3.50/M range. That's premium territory. But oh man, the reasoning.

The lineup:

Model Output $/M Best For
K2.5 $3.00 Heavy reasoning, research questions
Other variants up to $3.50 Similar premium tier

What won me over:

  • Reasoning benchmarks got the highest marks from me across the four. When I threw multi-step logic problems at K2.5, it didn't flinch.
  • Chinese-language generation felt the most natural of any model I tested.
  • Output coherence is incredibly high. It rarely loops or hallucinates compared to what I expected at the price.

Where it disappointed:

  • Speed. It clocks in noticeably slower than the others — I rated it ⭐⭐⭐ compared to DeepSeek's five stars.
  • No vision support whatsoever. Text only.
  • Cost is a real factor for a bootcamp grad's budget. Not my everyday model.

If you've got a reasoning task where quality matters more than cost, Kimi deserves a look. If you're running a chatbot that needs to reply in 200ms, look elsewhere.

GLM: The Underdog That Punches Above Its Weight

Last but absolutely not least: GLM. I almost missed this one entirely. A friend in my cohort mentioned Zhipu AI and I went "who?" That's embarrassing in hindsight because GLM-5 is genuinely fantastic.

The lineup:

Model Output $/M Best For
GLM-4-9B $0.01 Tiny tasks, batch processing
GLM-5 $1.92 Flagship quality at a fair price
Other variants up to $1.92/M Spread across the pricing range

What made me a fan:

  • Vision support through GLM-4.6V is solid. Image reasoning worked better than I expected.
  • Chinese-language output is top tier — tied with Kimi for the best I tested.
  • Pricing range from $0.01 to $1.92/M gives lots of room.
  • GLM-5 at $1.92/M felt like a sweet spot between Kimi pricing and lower-tier quality.

Where I struggled:

  • Code generation was the weakest of the four in my tests. ⭐⭐⭐ compared to DeepSeek's five.
  • Some inconsistency in output across different runs.
  • Smaller ecosystem in English-speaking dev circles — fewer Stack Overflow answers when I got stuck.

What I Actually Use Day to Day

Let me give you my real-world picks after living with these for a week, because theory is fun but I shipped actual projects:

  • Side projects and hackathons: DeepSeek V4 Flash. $0.25/M and it just works.
  • Tight budget client work: Qwen3-8B at $0.01/M for trivial stuff, Qwen3-32B at $0.28/M when quality matters.
  • When I need real reasoning: Kimi K2.5. Yes it's $3.00/M. Sometimes it's worth it.
  • Chinese content and image tasks: GLM-5 for text, GLM-4.6V when vision is involved.
  • Code reviews and refactoring: DeepSeek Coder or Qwen3-Coder-30B.

A small note about the code pattern — because this was the unlock for me as a bootcamp grad. All four work with the same OpenAI client code, just by changing the model string. Once I had my client object set up pointing at https://global-apis.com/v1, I could A/B test anything in minutes. That was the moment I went from "the API landscape is terrifying" to "I actually get this now."

The Real Lesson For Me

Here's the takeaway I didn't expect: the "best" Chinese API depends entirely on what I'm building. There's no single winner, which was frustrating at first. But once I accepted that, my code got cheaper and
