## Tracked benchmark scores

| Benchmark | Score | Source | What it measures |
| --- | --- | --- | --- |
| SWE-Bench Verified | 59.5% | Lab | Real coding tasks pulled from open-source projects — the AI has to find and fix actual bugs. A human-checked version of the original SWE-Bench. Higher is better. |
| Terminal-Bench 2.1 | 18.1% | Lab | Can the AI work in a command-line terminal — running commands and finishing technical setup tasks the way a developer would? Higher is better. |
| GPQA Diamond | 72.41% | Lab | Graduate-level science questions in biology, physics, and chemistry — hard enough that subject-matter PhDs score around 65%. Higher is better. |
| IFBench | 77.94% | Lab | Tests whether the AI can follow detailed instructions and satisfy multiple constraints at once. Higher is better. |

## About Nemotron Labs Dory 1.0 4B

Nemotron Labs Dory 1.0 4B was released on October 16, 2026 as the first model in NVIDIA's Nemotron Labs Dory line. Where the Nemotron 3 and 3.5 models use a hybrid Mamba-Transformer design, Dory is a 4-billion-parameter looped normalized-GPT: eight-layer input and output blocks around a twenty-layer recurrent block that can be applied again at inference. One checkpoint therefore serves different compute budgets, and NVIDIA recommended two loops as the default. Pretraining ran for 6 trillion tokens, the first 4.5 trillion of them in NVFP4, before the context was extended to 256,000 tokens.

NVIDIA released the weights under OpenMDW 1.1 in BF16, MXFP8, NVFP4 and a Q5_K_M GGUF. English is the supported language. At two loops it reported 72.41% on GPQA Diamond, 59.5% on SWE-Bench Verified, 18.1% on Terminal-Bench 2.1 with the Terminus-2 harness, and 77.94% on IFBench under strict constraint checking. On the equal-weight average of the 12 benchmarks in its technical report, two loops scored 39.67, above the 36.73, 32.59 and 32.21 NVIDIA recorded there for Gemma 4 26B-A4B, Gemma 4 12B and Qwen3.5-9B. One loop scored 35.17 on that average, under the 36.73 recorded for Gemma 4 26B-A4B.

Nemotron Labs Dory 1.0 4B was released by NVIDIA on Friday, Oct 16 2026.

### Who made Nemotron Labs Dory 1.0 4B?

Nemotron Labs Dory 1.0 4B was built by NVIDIA. The dominant AI chipmaker, publishing the open Nemotron model family. Ships weights, datasets and training recipes to seed demand for its hardware rather than to sell a chatbot.

### What benchmark scores did Nemotron Labs Dory 1.0 4B get?

Nemotron Labs Dory 1.0 4B reports 4 tracked benchmark scores — SWE-Bench Verified: 59.5%; Terminal-Bench 2.1: 18.1%; GPQA Diamond: 72.41%; IFBench: 77.94%. Tracked scores may come from lab reports or independent benchmarks; source details accompany the benchmark data.

### What is the context window of Nemotron Labs Dory 1.0 4B?

Nemotron Labs Dory 1.0 4B has a context window of 256k. Providers may specify separate input and output token limits.

### How many parameters does Nemotron Labs Dory 1.0 4B have?

Nemotron Labs Dory 1.0 4B is reported at 4B parameters.

### Is Nemotron Labs Dory 1.0 4B open source?

Partly. Nemotron Labs Dory 1.0 4B is an open-weight model: the trained weights are free to download and run locally or on your own infrastructure, but the training data and code are not fully released and the license may restrict some commercial uses. It is not open source in the strict sense.

### What came before and after Nemotron Labs Dory 1.0 4B?

NVIDIA's previous tracked release was Nemotron 3.5 Bolt 74B on Oct 15 2026, 1 day earlier. It was followed by Nemotron 3.5 Bolt E4B 4GB on Oct 23 2026.
