360 Zhinao 360智脑
Qihoo 360's LLM family
Overview
360 Zhinao is Qihoo 360's underlying LLM family, distinct from the consumer-facing 360 AI Search product. The model powers 360's enterprise AI, 360 browser AI features, and security-AI integrations across the company's antivirus product line. Open-sources select model checkpoints on Hugging Face.

Use cases
What you can produce with 360 Zhinao 360智脑
- Download the Apache 2.0-licensed 360Zhinao3-7B weights from Hugging Face or ModelScope and deploy them commercially at no licence cost.
- Feed an entire Chinese-language contract, report or book into the 360Zhinao2-7B-Chat-360K variant and query it in one pass thanks to the 360K-token context window.
- Run the Int4-quantised chat checkpoint on a single consumer GPU for local Chinese-language chat and summarisation without cloud API fees.
- Use the 360Zhinao-search embedding model to build a Chinese semantic-search or RAG pipeline that ranks at the top of the C-MTEB retrieval benchmark.
- Solve competition-style maths problems in Chinese with a 7B model that has led open-source Math benchmark scores in its size class.
- Fine-tune the 7B Base checkpoint on proprietary data using the training scripts published in Qihoo 360's GitHub repositories.
- Get AI-assisted threat detection and browsing answers inside 360's browser and security products, which run on the same Zhinao model line.
ASEAN Perspective

360 在中国桌面安全市场拥有几亿装机量，是其 AI 产品分发的护城河。
360 Zhinao is Qihoo 360's in-house large language model, powering chat and productivity features across the company's China-focused ecosystem. It performs reasonably on Mandarin tasks and benefits from integration with 360's security and browser products, making it a credible domestic option in China.
For an ASEAN or global reader the limitations dominate: it is China-first, with a Chinese-language interface, unclear international availability, and no well-documented public API or SDKs for outside developers. Data residency and compliance posture also make it a poor fit for non-China deployments. Useful mainly to Mandarin users already inside the 360 ecosystem.
What people say
360 Zhinao remains an active and, by 2026, an increasingly strategically important model family for Qihoo 360 — though it is best understood as infrastructure rather than a standalone product people subscribe to. The models power 360's enterprise AI offerings, browser features and, most visibly, the company's security stack: in mid-2026 founder Zhou Hongyi unveiled Tulong Feng, an AI vulnerability-hunting agent the company positions as China's answer to Western AI bug-finders, built on the same model line. Coverage in Forbes, The Register and Decrypt in June 2026 confirms the AI push is central to Qihoo 360's positioning, and the company remains the dominant player in Chinese PC security.
Among the developers who actually touch the models, reception is quietly positive. The open-sourced checkpoints — 360Zhinao2-7B and the newer 360Zhinao3-7B on Hugging Face and ModelScope under Apache 2.0, free for commercial use — have posted first-place results among sub-10B open models on several Chinese-language and competition-math benchmarks, and the 360Zhinao-search embedding model has ranked top of the C-MTEB retrieval leaderboard. The 360K-token long-context chat variants are a genuine differentiator at the 7B size.
The honest caveat is visibility. Unlike Qwen or DeepSeek, 360 Zhinao has little community mindshare outside China; discussion threads are sparse, English documentation is thin, and there is no meaningful body of third-party user reviews on platforms like G2 because it is not sold that way. Most people who benefit from it do so indirectly, inside 360's browser, search and antivirus products.
It genuinely fits Chinese-language developers who want a permissively licensed, small, benchmark-strong model for local or commercial deployment — especially for Chinese retrieval, long-document and maths-heavy tasks — and enterprises already inside the 360 security ecosystem. Teams needing English-first performance or an active global community should look elsewhere.
