Nemo Curator — Curate LLM training data: dedupe, filter, PII redaction
Nemo Curator — Curate LLM training data: dedupe, filter, PII redaction
Start with meaning, then move to detail.
This lesson explains Nemo Curator — Curate LLM training data: dedupe, filter, PII redaction as part of getting started with Hermes correctly. You will learn what it does, when it matters, and the smallest safe test that proves it works.
If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?
For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.
For advanced readers, inspect Skill metadata, Reference: full SKILL.md, When to use NeMo Curator, then verify failure modes and version compatibility.
No prior experience is required; follow the steps on a safe test setup first.
A clear outcome before you read.
- Understand Nemo Curator — Curate LLM training data: dedupe, filter, PII redaction without assumed prior knowledge.
- Separate the source description from what still needs testing in your environment.
- Read the first command and identify its inputs and outputs before copying it.
Short definitions before the details.
- Skill
- An instruction bundle that teaches Hermes a repeatable workflow without necessarily adding an external service.

# NeMo Curator 1.x installs with uv. Extras use hyphens (PyPI-normalized):
# text-cuda12 / text-cpu (and image/video/audio/math variants), or `all`.
# Text curation (CUDA 12)
uv pip install "nemo-curator[text-cuda12]"
# All modalities
uv pip install "nemo-curator[all]"
# CPU-only text (slower)
uv pip install "nemo-curator[text-cpu]"The 0.x-style snippets in the sections that follow illustrate the *concepts* (quality
filtering, exact/fuzzy/semantic dedup, PII redaction, classifier filtering). For runnable
1.x code, map each concept onto the corresponding stage from the modality guide.
## Data curation pipeline
### Stage 1: Quality filtering### Stage 2: Deduplication
**Exact deduplication**:Read the first command and identify its inputs and outputs before copying it.
Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.
