How to use this tool
Start one concrete task and provide the needed background, desired format, constraints, and evidence standard.
For research, ask Z.ai to search and organize sources, then open the cited pages and check whether they support each claim.
For code, specify the language, runtime, dependencies, and tests, then execute the result in a safe development environment.
For images, documents, or presentations, remove confidential content and confirm which multimodal capability is available in the current chat experience.
Revise the output for accuracy and audience, and require qualified review for work affecting security, customers, policy, health, law, or money.
