Chinese AI Model Uses Less Muscle for Coding Tasks
Zain Hasan, an AI engineer at Together AI, has taught himself to use AI coding assistants while still keeping an eye on cost. He directs difficult problems to a frontier model, meaning one near the current state of the art in reasoning and capability, such as Anthropic's Fable. But if the task that Hasan is outsourcing is more straightforward, he directs it to a less capable-and less expensive-language model.
Key Takeaways
- Right now, the cheaper model, for him, tends to be GLM 5.2.
Those that pay Z.ai for GLM access still can save money, because the company's API costs US $4.40 per million output tokens .
- And when someone else is paying, the rational move for many software engineers is to skip tabulating costs entirely.
- The model nearly ties Opus 4.8's score on some agentic coding benchmarks, such as FrontierSWE and PostTrainBench .
Cybersecurity researchers have also found that GLM 5.2 scores well in cybersecurity benchmarks , a capability that spurred comparisons to Anthropic's Mythos .
- The model's Chinese origin also complicates its use for companies in the U.S. and elsewhere that are wary of routing sensitive data through Chinese-linked infrastructure.
- Many of the report's benchmarks place GLM 5.2 behind Opus 4.8 (and, at times, OpenAI's GPT-5.5) in agentic coding.
Stats & Key Facts

- #Z.ai Narrows Benchmark Gap With U.S. Rivals Z.ai's GLM 5.2 is an AI large language model (LLM) with 753 billion parameters, though it has only 40 billion parameters active at once-an optimization that improves the speed at which a model can respond.

That's less than a fifth of the comparable price for access to Anthropic's Opus 4.8 model, and a tenth the price of Anthropic's Fable coding model. An output token is the basic unit of text a model generates in response to a prompt. Yet many software engineers around the world, Hasan said, aren't yet fully mindful of the net AI price tag for a given coding project.
"A lot of companies right now-they're still trying to figure this technology out, and so there isn't really a token budget," said Hasan. And when someone else is paying, the rational move for many software engineers is to skip tabulating costs entirely. "The easiest thing is to pick the most powerful model."
