Embedl's device farm (embedl.com) lets you test Hugging Face models on real Jetson boards from the browser for free — pick a device, type a prompt or upload an image, and get runtime stats; 1000+ models supported. Highlight: Cosmos3-Edge didn't fit on Orin Nano Super 8GB in BF16, but INT4 quantization brings peak VLM memory to 3.3GB, hitting 152.5 tok/s on Orin Nano Super and 207.8 tok/s on AGX Thor 128GB (vs 44.1/68.2 tok/s with BF16 vLLM), while accuracy holds across five VLM benchmarks (65.56 → 65.20). VLM part is live; diffusion and policy components coming soon.
