Show HN: How We Run 60 Hugging Face Models on 2 GPUs

Most open-source LLM deployments assume one model per GPU. That works if traffic is steady. In practice, many workloads are long-tail or intermittent, which means GPUs sit idle most of the time.

We experimented with a different approach.

Instead of pinning one model to one GPU, we: •Stage model weights on fast local disk •Load models into GPU memory only when requested •Keep a small working set resident •Evict inactive models aggressively •Route everything through a single OpenAI-compatible endpoint

In our recent test setup (2×A6000, 48GB each), we made ~60 Hugging Face text models available for activation. Only a few are resident in VRAM at any given time; the rest are restored when needed.

Cold starts still exist. Larger models take seconds to restore. But by avoiding warm pools and dedicated GPUs per model, overall utilization improves significantly for light workloads.

If anyone here is running multi-model inference and wants to benchmark this approach with their own models, I’m happy to provide temporary access for testing.
