Background

In 2025, domestic large models entered the second half of the "Hundred Models War". DeepSeek, Zhipu GLM, and Tongyi Qianwen each have their strengths. How should developers choose?

This article provides a comprehensive horizontal comparison from four dimensions: reasoning ability, Chinese understanding, code generation, and price.

Contestants

Model	Vendor	Positioning
DeepSeek V4	DeepSeek	Flagship All-rounder
GLM-5	Zhipu AI	Chinese Specialization
Qwen-Plus	Alibaba Tongyi	King of Cost-effectiveness

Reasoning Ability

DeepSeek V4 performs best in mathematical reasoning and logical deduction. It maintains a leading position on benchmarks such as GSM8K and MATH.

GLM-5 excels in common sense reasoning within Chinese contexts, making it suitable for scenarios requiring deep understanding of Chinese semantics.

Qwen-Plus has balanced reasoning capabilities, fully sufficient for everyday Q&A scenarios.

🏆 Reasoning Ability Ranking: DeepSeek V4 > GLM-5 ≈ Qwen-Plus

Chinese Understanding

GLM-5 has a natural advantage in Chinese understanding tasks—performs best in classical Chinese translation, idiom comprehension, Chinese NLU, etc.

Qwen-Plus benefits from Alibaba's rich Chinese corpus, producing fluent and natural Chinese text.

DeepSeek V4 also has first-class Chinese capabilities, but slightly lags behind GLM-5 in extremely refined Chinese tasks.

🏆 Chinese Understanding Ranking: GLM-5 > Qwen-Plus ≈ DeepSeek V4

Code Generation

DeepSeek V4 is far ahead in code generation capabilities. It significantly outperforms on code benchmarks such as HumanEval and MBPP.

Qwen-Plus has good code generation quality, suitable for daily development assistance.

GLM-5 performs average on general code tasks.

🏆 Code Ability Ranking: DeepSeek V4 >> Qwen-Plus > GLM-5
