# NVIDIA Nemotron 3 Nano 4B vs NVIDIA Nemotron 3 Ultra 550B-A55B

Put two to four models side by side on the fields that decide a deployment: context, price, region, license, languages, hosting, and what is verified.

Where two models differ, this table shows the difference and stops. LLM EU publishes no winner badge without a documented score for that task, and a missing figure stays missing instead of becoming a zero.

## When to use it

### [NVIDIA Nemotron 3 Nano 4B](/en/models/nemotron-3-nano-4b/)

#### Strengths

- long context for a 4B model
- high published maths scores for its size
- runs on a single small accelerator

#### Limits

- English only, per the model card
- vendor licence rather than an OSI one
- benchmark figures come from NVIDIA%E2%80%99s own harness

#### Tasks

[Low cost](/en/tasks/cheap/), [Reasoning](/en/tasks/reasoning/), [Retrieval (RAG)](/en/tasks/rag/), [Summarisation](/en/tasks/summarization/)

### [NVIDIA Nemotron 3 Ultra 550B-A55B](/en/models/nemotron-3-ultra-550b-a55b/)

#### Strengths

- open weights are published on Hugging Face and can be downloaded without a vendor agreement
- the model page lists 6 languages the European Union publishes in, including en, fr, es, it

#### Limits

- catalogue only %E2%80%94 LLM EU does not run this model, and nothing on this card implies an LLM EU endpoint
- no evaluation has been run by LLM EU
- the openmdw-1.1 (other) licence is a custom agreement whose commercial terms were not established from its published text, so commercial serving is not permitted until a human clears it; the router must not route to it
- the published configuration records no context window, so the card carries none
- at 560.5B parameters, self-hosting needs a multi-node deployment rather than a single server
