Chinese AI Models vs GPT-4o: The 40x Savings Claims, With Catches

Originally published on NextFuture

A $400 monthly AI bill is pushing developers toward Chinese AI models that claim to cost up to 40 times less. Two posts lay out the exact price tables and benchmarks behind that pitch. Both also undercut their own headline numbers, in their own text.

The claimed numbers

One developer, writing about a side project, said an OpenAI bill topped $400 in a single month after running GPT-4o "for almost everything — classification, summarization, the whole nine yards." At $10 per million output tokens, he wrote, the cost "starts to hurt when you're processing thousands of docs a month."

The same post lists a side-by-side price table for three US models and four Chinese ones:

ModelInput ($/M tokens)Output ($/M tokens)

GPT-4o$2.50$10.00

Claude 3.5 Sonnet$3.00$15.00

Gemini 1.5 Pro$1.25$5.00

DeepSeek V4 Flash$0.18$0.25

Qwen3-32B$0.18$0.28

GLM-5$0.73$1.92

Kimi K2.5$0.59$3.00

Prices as listed in the developer's post comparing US and Chinese model providers; not independently verified by this outlet.

Run the math on that table and the ratio checks out: GPT-4o's $10 output price is roughly 40 times DeepSeek V4 Flash's $0.25 — consistent with the multiple the developer cites below.

To back the savings case, the developer says he "ran a bunch of benchmarks" on his own workloads. He reports GPT-4o scoring 88.7 against DeepSeek V4 Flash's 85.5 — a 3-point gap that he says comes "for 40× cheaper." On HumanEval, he lists DeepSeek V4 Flash at 92.0 versus GPT-4o's 92.5, a margin he says was close enough that he "had to triple check those numbers."

Neither comparison comes from a neutral test suite. Both figures are the outcome of workloads the author picked and ran privately — a different exercise than an independent evaluation, and one that matters more the larger the claimed gap gets.

The access catch

Signing up isn't simple, according to the same post. "I went to DeepSeek's website. They want a Chinese phone number for verification. I went to Qwen/Alibaba Cloud. They want WeChat Pay or Alipay," the developer wrote. His summary: the Chinese models are "technically incredible and dirt cheap," but "you basically cant access them from the US without jumping through hoops."

That friction changes the calculus for any team pricing out the switch. A cheaper token rate only pays off once someone has cleared the phone-verification and payment hurdles — a cost the price table above doesn't capture.

Read the fine print

A separate self-hosting guide makes a bolder claim: running Qwen2.5 72B — "Alibaba's flagship reasoning model," per the guide — for $6 a month, versus Claude Opus at $15 input / $60 output per million tokens. The guide lists AWS's p3.2xlarge cloud GPU instance at $24.48 an hour, or $17,600 a month, as the alternative its setup is built to undercut.

The trick, it says, is AWQ quantization that shrinks the model from 144GB to 36GB, combined with vLLM's batching engine. The author says he has "tested this with 500+ concurrent requests" and that "it doesn't break."

The guide's own math tells a different story than its title. A DigitalOcean GPU Droplet actually costs $0.20 an hour for compute plus $5 a month for the GPU — $11 a month, not $6.

The author explains the gap himself: "Wait—I said $6/month in the title. Here's why: use the DigitalOcean referral link (yes, it matters), get $200 credit, and the first 33 months are free." The advertised price depends on a referral credit, not a standing rate.

The same guide reports its quantized model "scores 1.2-2.3% lower" on MMLU, GSM8K and ARC-Challenge than the unquantized version, calling that gap "acceptable for production." Like the price comparison, that judgment comes from the model's own test run, not an outside benchmark.

The pattern repeats across both posts: the number in the headline is the best case, and the number in the body is the one that survives scrutiny.

What to watch

• Whether the $6-a-month figure holds once the DigitalOcean referral credit runs out — the guide's own numbers put the standing cost at $11 a month.




• Whether DeepSeek and Qwen ease their sign-up requirements, since the cost-comparison post names phone verification and WeChat Pay or Alipay as the main barrier to access from the US.




• Whether the benchmark gaps cited — a 3-point difference between GPT-4o and DeepSeek V4 Flash, a 1.2-2.3% gap on the quantized Qwen model — hold up under testing run by someone other than the model's own advocate.
