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.
