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.

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.

    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.
