Real-world applications: where GLM 4.5 shines
GLM 4.5 was designed for scenarios where generic models face limitations. Among its applications are:
Software Engineering
With high performance in benchmarks such as SWE-bench Verified (64.2) and Terminal Bench (37.5), it positions itself as an excellent option for automating complex coding tasks.
Assistants and Independent Agents
In the tests TAU-bench and BrowseComp, GLM 4.5 outperformed models like Claude 4 and Qwen, proving to be effective in environments where interaction with external tools is essential.
Complex data analysis and reporting.
With its strong contextual capabilities, the model can synthesize extensive reports, generate insights, and analyze lengthy documents efficiently.

Comparison with GPT-4, Claude 3 and Mistral: performance versus cost
One of the most notable aspects of the GLM 4.5 is its significantly lower cost compared to models such as... GPT-4, Claude 3 Opus and Mistral Large, even though it offers comparable performance across various benchmarks.
For example, while the average cost of generating tokens with GPT-4 can exceed US$ 30 per million tokens generated, The GLM 4.5 operates with averages of US$ 2.2 per million output, with even more affordable options such as GLM 4.5-Air for only US$ 1.1.
In terms of performance:
- Claude 3 It excels in linguistic reasoning tasks, but GLM 4.5 comes close in mathematical reasoning and code execution.
- Mistral It excels in speed and local compilation, but doesn't reach the contextual depth of 128k tokens like GLM 4.5.
- GPT-4, Although robust, it demands a high price for performance that in many scenarios is matched by GLM 4.5 at a fraction of the cost.
This cost-effectiveness positions the GLM 4.5 as an excellent choice for startups, universities, and data teams looking to scale AI applications on a budget.
Performance comparison with other LLMs
GLM 4.5 not only competes with the big names in the market, but also surpasses them in several metrics. In terms of reasoning and execution of structured tasks, it achieved the following results:
- MMLU-Pro: 84.6
- AIME24: 91.0
- GPQA: 79.1
- LiveCodeBench: 72.9
