NVIDIA releases Nemotron-Labs-Dory 4B, a looped model where you pick how much compute to spend per task
Released Oct 16 under the OpenMDW license, Dory 1.0-4B reruns a shared 20-layer block a chosen number of times, so one checkpoint trades speed for accuracy with no model swap; NVIDIA's own tests put it at 50.3 on SWE-bench Verified with 1 loop and 61.8 with 4. It has a 256K English context and ships in BF16, MXFP8, NVFP4, and Q5_K_M GGUF.
