System Architecture
Core Components
The Open LoRA system is built on a modular architecture consisting of:
LoRA Adapters Storage
Stores fine-tuned LoRA adapters in OpenLedger
Adapters are loaded dynamically when needed rather than preloading all into memory.
Model Hosting & Adapter Merging Layer
Uses a shared base model, while LoRA adapters are merged on-the-fly during inference.
Supports ensemble merging of multiple adapters to improve inference performance.
Inference Engine
Implements efficient CUDA optimizations, including:
Flash-Attention for reducing memory overhead.
Paged-Attention for efficient handling of long sequences.
SGMV Optimization (Sparse General Matrix Vector multiplication) to accelerate inference.
Request Router & Token Streaming
Routes API requests dynamically based on required adapters.
Streams generated tokens efficiently using optimized kernel implementations.
Attribution Engine
Automatically records which models, adapters, and data were used for each inference.
Ensures fair and verifiable attribution to all contributors (developers, data providers, compute nodes).
Enables reward distribution based on real-time usage tracking.
OpenLedger Network
Decentralized infrastructure that connects storage, inference, and attribution components.
Uses smart contracts for access control, attribution logging, and token-based rewards.
Ensures secure, scalable, and trustless coordination across the AI pipeline.
