September 2 News.ZhipuAnnouncing the launch of Claude Code's exclusive developer package "GLM Coding Plan" starting September 1 - $20~$100 per month for the latest flagship model of Smart Spectrum! GLM-4.5 and GLM-4.5-Air.
According to the introduction, the first phase of this package mainly pushes Claude Code, and will be expanded to more Coding tools in the future.1AI learned from the official, at present, GLM-4.5 has access to a number of mainstream programming tools, including Claude Code, Cline, Gemini CLI, Grok CLI, CodeGeeX, Kilo Code, Roo Code, Trae, and so on. GLM-4.5 has access to many mainstream programming tools including Claude Code, Cline, Gemini CLI, Grok CLI, CodeGeeX, Kilo Code, Roo Code, Trae.
According to Smart Spectrum, GLM-4.5 shows stable and practical performance in typical scenarios such as front-end development, cross-file modification, and full-stack project construction, etc. According to feedback, its ability to solve practical problems is close to that of Claude Sonnet 4. According to the feedback, its ability to solve real-world problems is close to that of Claude Sonnet 4. GLM-4.5 also maintains the same competitiveness with the international mainstream models in several open source evaluations:
- WebDev Arena: tied for second place with leading global models;
- SWE-bench Verified: outperforms Gemini-2.5-Pro and GPT-4.1;
- BFCL v4 benchmark: No. 1 in the world, surpassing Claude Opus 4.1 and costing only 1.5%.
In order to evaluate the Agentic Coding capability of the model, Smart Spectrum also constructed a CC-Bench evaluation system and compared GLM-4.5 with Claude Sonnet 4, DeepSeek-V3.1, Kimi-K2, and Qwen3-Coder-480B on 52 real-world programming tasks covering six development domains.
The results show that GLM-4.5 performs well among the open source models, especially in terms of task completion results and tool invocation reliability.GLM-4.5 is close to Claude Sonnet 4 in terms of coding performance, but at 1/7th of the price.
