Why low: partial agreement (40 of 47 strings) with nvidia/nemotron-nano-9b-v2:free only.
NVIDIA: Nemotron Nano 12B 2 VL (free) is NVIDIA's model. Its measured tokenizer sits with the Mistral group, which is evidence that it builds on the Mistral tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against NVIDIA's authorship of the model itself.
| We checked | What we found | Where it came from |
|---|---|---|
| How it counts tokens | Counted, using the 47 strings that came back reliably | we measured it |
| How its API is set up | A combination of settings no other listing in the catalogue uses | api_22e5c378 |
| How much it can read and write | Reads up to 128,000 tokens at once, writes up to 128,000 | its own listing |
| Whether it thinks before answering | Reasons when asked to | its own listing |
| Who served our requests | Nvidia | we measured it, 21 August 2026 |

We sent NVIDIA: Nemotron Nano 12B 2 VL (free) fifty short pieces of text and recorded what each one cost it in tokens. The bars below are those costs. Two models built on the same tokenizer produce the same bars; a model built on a different one produces a different set, which is what makes this a fingerprint.
An x marks a row excluded as corrupt (caching or provider interference detected during measurement). Overhead subtracted: 15 prompt tokens.
NVIDIA Nemotron Nano 2 VL is a 12-billion-parameter open multimodal reasoning model designed for video understanding and document intelligence. It introduces a hybrid Transformer-Mamba architecture, combining transformer-level accuracy with Mamba’s...

* NVIDIA: Nemotron Nano 12B 2 VL (free) no longer appears in the OpenRouter catalogue, first absent from the snapshot of 3 September 2026. The record stays because the measurements above were real when they were taken and this address has been published.
