AirLLM runs 70B model inference on a single 4GB GPU

AirLLM 70B inference with single 4GB GPU

AirLLM is an open-source library that runs large models on consumer GPUs. It splits a model like Llama 3 70B into layers and loads them one at a time into VRAM, so a single 4GB GPU can handle inference without multi-GPU setups. It supports Llama, Mistral, ChatGLM, and other common architectures, and works with HuggingFace models. The trade-off is slower speed, but it lowers the hardware bar for local LLM inference to laptop level.

Why it matters: Fitting a 70B model onto a single 4GB GPU via layer-by-layer loading isn't a new idea, but the out-of-the-box engineering is solid. Speed is the obvious tradeoff, and the post doesn't give concrete latency numbers, so the score stays at the featured threshold.
