DeltaZip solves the challenge of serving multiple fine-tuned LLMs concurrently by introducing aggressive delta compression while maintaining model quality.

• Compresses model parameter differences (deltas) between fine-tuned models by up to 10x
• Efficiently handles sporadic and bursty request patterns across multiple LLMs
• Maintains high quality results despite significant compression
• Enables cost-effective deployment of multiple specialized LLMs

This innovation is critical for engineering teams deploying multiple custom LLMs in production environments where computing resources are constrained but model quality cannot be compromised.
