LoRAX is an open-source framework developed by Predibase, designed to efficiently serve and manage hundreds of fine-tuned large language models (LLMs) using a single GPU. Released under the Apache 2.0 license, LoRAX aims to democratize AI by reducing the costs associated with serving fine-tuned models, leveraging components such as Dynamic Adapter Loading, Tiered Weight Caching, and Continuous Multi-Adapter Batching. This approach allows for fast and scalable deployment, accommodating multiple models with minimal latency and throughput degradation. The framework integrates with existing infrastructures like Kubernetes and provides pre-built Docker images for ease of use. By fostering a collaborative community, Predibase seeks to innovate in the realm of generative AI, emphasizing smaller, faster, and more affordable LLMs. LoRAX also supports popular LLM architectures such as Llama 2 and Mistral, and pairs with Predibase's Reinforcement Fine-Tuning for enhanced model deployment, making it a commercially viable option for businesses seeking to utilize AI at scale.
