Agentic and multi-step workflows
Reliable tool-calling and instruction-following suit agent loops that plan, call tools, and iterate.

Complex reasoning
Extended reasoning improves reliability on multi-step math, logic, and technical analysis.

Long-document analysis
Summarize and extract from contracts, papers, and reports without aggressive chunking.

Use cases

GLM-4.5V is documented as suited to webpage coding, where it can analyze webpage screenshots or screen recordings, understand layout and interaction logic, and generate usable webpage code.

It is also documented for grounding tasks, including precisely identifying and locating target objects for practical uses such as security checks, quality inspections, content reviews, and remote sensing monitoring.

Another documented use case is GUI agent work, where it can recognize and process screen images and support actions like clicking and sliding for operational tasks.

It is further documented for complex long document interpretation, including summarization, translation, chart extraction, and producing insights from lengthy documents.
