What Z.ai is

Z.ai is the overseas-facing assistant from Zhipu AI, a Chinese model developer. The chat runs in the browser at chat.z.ai and is built on the company's GLM model family; its own description highlights website building, code writing, long-horizon task execution and fast answers. In practice that puts it between a general chatbot and a coding assistant: you can ask it to scaffold a page, explain an error, work through a multi-step task, or simply answer a question. Long-horizon tasks are the advertised differentiator — handing over a goal and letting the model work through the steps instead of answering one prompt at a time. The interface is a standard chat with file and image input. Documentation and support are thinner in English than for Western equivalents, and published detail on data handling is limited, which matters for regulated work. Treat it as a capable low-cost option to benchmark against whatever assistant you already pay for.

Best for

Scaffolding small websites and front-end components
Multi-step tasks you would rather hand off than click through
Cost-sensitive teams benchmarking GLM against Western models

Not ideal for

Procurement that requires published compliance documentation
Support workflows that depend on fast English-language responses

Pros

Free access to a current GLM model
Coding and website building in the same chat
Handles longer task chains than a single-turn bot

Cons

English documentation and support are limited
Data-handling details are not well documented
Model behaviour and usage limits change frequently

Pricing in detail

The chat at chat.z.ai can be used free of charge, with limits that apply during busy periods. Zhipu sells API access to the same model family separately, priced per token rather than per seat. There is no published per-seat plan for the chat interface, so teams should confirm capacity and terms directly before depending on it.
