RuiPath 2.0 uses seven billion parameters; its two-million-parameter Edge version runs directly on ordinary hospital PCs.

Ruijin Hospital (瑞金医院) and Huawei Cloud jointly released the RuiPath 2.0 pathology model at the 2026 Medical Artificial Intelligence Innovation Forum in Shanghai. The primary RuiPath 2.0 model has seven billion parameters.

The developers said the model provides precise, interpretable labeling across dimensions including histological subtype, depth of invasion and mitotic figures. These are pathology-analysis functions rather than general-purpose conversational-model capabilities.

They also introduced RuiPath 2.0 Edge, a lightweight model containing two million parameters. The Edge version can be deployed directly on an ordinary hospital personal computer, according to the release.

The source does not provide diagnostic-accuracy percentages, inference latency, hardware requirements for the seven-billion-parameter model, regulatory-approval status or a count of hospital deployments. The announcement therefore establishes the model sizes, stated pathology functions and local deployment capability, but not clinical outcomes.
