Nexus Labs cuts costs by serving 40 LoRA adapters on one Llama 3.1 model

By PulseAugur Editorial · [1 sources] ·

Nexus Labs has developed a cost-effective method for serving multiple LoRA adapters on a single base model, significantly reducing infrastructure expenses. By utilizing vLLM's multi-LoRA serving capability, they consolidated 40 customer-specific adapters onto two A100 GPUs, cutting monthly costs from an estimated $24,000 to a fraction of that. While this approach introduces a small latency tax and requires careful evaluation to ensure output consistency, it proves highly efficient for enterprise deployments with diverse customer needs. AI

IMPACT Enables significant cost reductions for enterprises deploying customized LLMs, potentially accelerating adoption of fine-tuned models.

    Serving 40 LoRA adapters on one base model: the throughput we got

    <p><strong>TL;DR: We fine-tune one LoRA adapter per enterprise customer on top of a single Llama 3.1 8B base. Running them as 40 separate deployments would have cost roughly $24k/month in mostly-idle GPU. Multi-LoRA serving in vLLM put all 40 on two A100s. Numbers and the parts t…
