A large sparse model with a 9B active parameter footprint despite its 75B total size, meaning it punches with efficiency on each token while carrying broad knowledge in its inactive weights. It operates on NVFP4 precision, NVIDIA's own numeric format, which ties it closely to NVIDIA hardware for optimal performance. The 'Puzzle' naming suggests a specialized focus, but concrete details about its task orientation are limited beyond its text-in, text-out design.
