Quark-sourced search — Alibaba's index, strong on commerce & lifestyle.
BigModel operates search_pro_quark through its tools API as a Quark-backed web-search engine, not as a normal chat-completions model.
TheRouter exposes it as zhipu/search-pro-quark on /v1/chat/completions, translating the tools response into markdown result lines, url_citation annotations, and usage.web_search_requests billing metadata.
search-pro-quark routes through Alibaba's Quark search index. Quark performs particularly well on commerce, lifestyle, health, education, and technology queries inside the Chinese internet, surfacing different rankings than Sogou for the same query.
If you're building an assistant for Chinese consumer-facing topics — shopping, travel, health, gadgets — Quark often returns more practical results than the general-purpose engines.

-d '{"model":"zhipu/search-pro-quark","messages":[{"role":"user","content":"Find recent Chinese e-commerce logistics updates with sources"}],"search_recency_filter":"oneWeek","content_size":"high"}'The launch added zhipu/search-pro-quark alongside search-std, search-pro, and search-pro-sogou as first-class /v1/chat/completions aliases with citation annotations and per-request billing.
The rate-card sweep found that z.ai publishes only one USD Web Search SKU and no separate USD search-pro-quark price; TheRouter therefore labels Quark pricing as a platform per-request price rather than an official vendor USD list price.
No. It is a Quark-backed web-search alias exposed through the chat-completions envelope for SDK compatibility. Use it to retrieve cited web results, then pass those results to a separate model for synthesis if you need a polished answer.
Both are premium partner-index search routes under BigModel. search-pro-quark routes through Quark and is positioned for vertical content such as commerce, lifestyle, health, and education; search-pro-sogou routes through Sogou and is positioned for Tencent ecosystem, news, Zhihu, encyclopedia, and medical coverage.
No. BigModel's tools endpoint does not support partial streaming. TheRouter accepts stream=true for compatibility, but emits one complete result chunk and then [DONE].
The model is priced per request. Successful search calls include usage.web_search_requests: 1, and prompt/completion token counters are zero for this alias.
