NVIDIA Nemotron Labs Dory1.0 4B BF16 — Hardware Requirements & GPU Compatibility
ChatFunctionsNVIDIA-Nemotron-Labs-Dory1.0-4B-BF16 is a 4 billion parameter looped model from NVIDIA Labs, built for general-purpose reasoning on a small footprint. It applies a shared block of layers repeatedly, so one checkpoint can trade inference compute for accuracy by changing the loop count, and it mixes sliding-window and full-attention layers. NVIDIA recommends two loops as the default. A Q4 build needs roughly 2.5 GB of memory, so it fits almost any GPU and many CPU-only machines. The context window is up to 256K tokens, and the model supports English. It is released under the OpenMDW-1.1 license and was published on October 16, 2026. Its card says last-loop KV caching avoids extra cache memory as loops are added, and that it was pre-trained natively in NVFP4 before continuing in BF16. It also lists BF16, MXFP8, NVFP4, and Q5_K_M formats. vLLM support is still in a pull request, and llama.cpp support requires building from a Dory-enabled source tree.
