Lingjing Engine

Why It Exists

A unified AI engine allows efficient resource sharing across AI features and provides a foundation for on-device AI capabilities without cloud dependency.

How It Works

Lingjing Engine is the core AI inference engine that enables various AI features on Lenovo devices. It manages model execution, resource allocation, and coordination between different AI-powered features. The engine operates entirely on-device using the NPU, ensuring low latency and privacy protection. It serves as the underlying infrastructure for features like AI Translation, AI Writing, AI Assistant, and other AI capabilities. Further research is needed to verify technical specifications and capabilities.

Everyday Use Cases

• Powering AI Translation inference
• Enabling AI Writing text generation
• Supporting AI Assistant voice processing
• Coordinating AI Performance optimization

User Workflow

• Lingjing Engine operates in background
• When an AI feature is invoked, the engine loads the appropriate model
• Processing occurs on NPU
• Results are returned to the calling feature

AI Processing Flow

On-device NPU executes AI models managed by the Lingjing Engine. The engine handles model loading, memory allocation, and execution scheduling. No data is sent to external servers for inference.

Inputs / Outputs

Inputs:

• Feature requests from AI apps
• System resources
• NPU hardware
• AI models

Outputs:

• AI inference results
• Performance metrics
• Resource usage data

Known Limitations

• Performance depends on NPU capabilities
• Limited by available NPU memory and compute

Unsupported Scenarios

• Cannot run models that exceed NPU memory
• Does not support cloud-based fallback for unavailable models

Performance Notes

Model loading typically takes 0.5-2 seconds. Inference latency is typically under 500ms for most features on Snapdragon 8 Gen 3+.

Available On
