Qwen 3.5 vs DeepSeek V4 Pro vs GLM-5: Chinese AI Model Showdown

Three Chinese AI labs — Alibaba (Qwen), DeepSeek, and Zhipu (GLM) — each have a flagship model competing for developer attention. All three are available through AIWave via a single OpenAI-compatible API key.

This comparison covers the factors that actually matter when choosing between them.

Specs at a Glance

	Qwen 3.5 397B	DeepSeek V4 Pro	GLM-5
Input (USD/1M)	$0.46	$0.42	$0.20
Output (USD/1M)	$0.92	$0.84	$0.60
Context	128K	1M	128K
Max output	8K	384K	8K
Provider	Alibaba	DeepSeek	Zhipu AI

Prices from AIWave. Model names: qwen3-coder-480b, deepseek-reasoner, glm-4-plus.

GLM-5 is the cheapest. DeepSeek V4 Pro has the largest context. Qwen 3.5 is the most expensive of the three but the largest parameter count.

Coding

• DeepSeek V4 Pro — Best coding model of the three. 92.1% on HumanEval. The 1M context window means you can feed entire small-to-medium codebases without chunking.
• Qwen 3.5 397B — Strong coding, especially on Python and JavaScript. Coder variant (qwen3-coder-480b) is tuned specifically for code.
• GLM-5 — Adequate for standard tasks. Falls behind on complex multi-file changes.

Recommendation: Coding → DeepSeek V4 Pro

Chinese Language

• GLM-5 — Best Chinese output quality. Near-native fluency on business, legal, and technical content. Trained by Zhipu AI, which specializes in Chinese NLP.
• Qwen 3.5 — Very strong Chinese. Alibaba's training data covers a wide range of Chinese web content.
• DeepSeek V4 Pro — Good Chinese, slightly less natural than GLM-5 on creative writing.

Recommendation: Chinese content → GLM-5

Cost

200 calls/day, 4K input + 2K output, 22 work days.

Model	Monthly Cost
GLM-5	$9
DeepSeek V4 Pro	$13
Qwen 3.5 397B	$14
DeepSeek V4 Flash	$4
GPT-4o	$154

Formula: (4K/1M x input + 2K/1M x output) x 200 x 22.

All three Chinese models cost roughly 1/10th to 1/15th of GPT-4o for the same workload.

The Pragmatic Approach

Most developers don't need to pick just one. AIWave routes all three through the same API — switch with a single model parameter. Use GLM-5 for Chinese content, DeepSeek V4 Pro for coding, and V4 Flash for bulk tasks. The $1 free credit covers hundreds of queries across any model to find what works for your specific workload.
