- Recipe files: `src/nemotron/recipes//`
- CLI files: `src/nemotron/cli/commands//`
- - Default configs: `src/nemotron/recipes//stage*/config/default.yaml`
- - Help and dry runs: `uv run nemotron --help`, `uv run nemotron -c default -d`

## Safe Workflow
-1. Gather only context relevant to the task: corpus path, existing SDG/training/eval data, target stage range, output directory, checkpoint path, execution mode, GPU IDs, and whether required secrets are configured. Never ask users to paste secret values.
+1. Gather only context relevant to the task: recipe family, selected profile, corpus path, existing SDG/training/eval data, target stage range, artifact root, checkpoint path, execution mode, GPU IDs, and whether required secrets are configured. Never ask users to paste secret values.
2. Start with cheap checks before expensive work:
- `uv run nemotron --help`
- `uv run nemotron --help`
- - `uv run nemotron -c default -d`
- - `uv run nemotron run -c default -d --from --to `
+ - `uv run nemotron -c -d`
+ - `uv run nemotron run -c -d --from --to `
- `run --help` may omit inherited `-c` and `-d` options even though `run -c default -d ...` works; validate by running the dry-run when unsure.
- In an already prepared checkout, `uv run --no-sync ... --help` or `uv run --no-sync ... -d` can avoid unexpected dependency sync during read-only checks.
3. Check prerequisites for the requested stage:
- Repo environment: `uv sync --all-extras` or the smallest relevant extra if documented by the repo.
- Stage 0 SDG: `NVIDIA_API_KEY`.
- - Stage 1-4 GPU work: CUDA/NVIDIA driver availability and enough VRAM.
- - Stage 4 export: the NeMo Export-Deploy container when using TensorRT.
- - Stage 5 deploy: Docker, NGC access, and `NGC_API_KEY`.
+ - Stages 1–3 GPU work: CUDA/NVIDIA driver availability and enough VRAM.
+ - Stage 4 export: the NeMo Export-Deploy container when using TensorRT. Default Nemotron 3 Embed skips this stage.
+ - Stage 5 deploy: Docker plus the selected backend's image and artifact contract; default Nemotron 3 may use the checked-in vLLM image without NIM credentials. Load the family reference before requiring NGC credentials.
- Remote execution: root `env.toml` profile for `--run` or `--batch`; load `references/remote.md` when remote scheduling, logs, or GPU placement matter.
-4. Use dotlist overrides instead of editing defaults unless the user asks for reusable config changes. Keep sequence length, prefixes, pooling/normalization, prompt templates, and hard-negative counts consistent across stages.
+4. Use dotlist overrides instead of editing defaults unless the user asks for reusable config changes. Keep the selected profile, artifact root, sequence length, prefixes, pooling/normalization, prompt templates, and hard-negative counts consistent across stages.
5. Avoid launching API, GPU, Docker, Slurm, NIM, or long-running jobs unless the user explicitly asked to run them. Offer or run dry-runs, config review, and small pilots first.
-6. If the user specifies GPU IDs, scope every stage command with `CUDA_VISIBLE_DEVICES=`.
-7. For multi-stage local runs, prefer `uv run nemotron run -c default --from --to `. The default `run` target stops at `eval`; `export` and `deploy` are opt-in.
+6. For local execution, scope requested GPU IDs with `CUDA_VISIBLE_DEVICES=`. For `--run` or `--batch`, configure scheduler resources such as `gpus_per_node` in the selected `env.toml` profile and let the scheduler assign devices; do not assume submit-shell `CUDA_VISIBLE_DEVICES` propagates remotely.
+7. For multi-stage local runs, prefer `uv run nemotron run -c --from --to `. Use `default` for rerank. The default `run` target stops at `eval`; `export` and `deploy` are opt-in.
8. When evaluating quality, compare against the base model on a fixed held-out evaluation set before recommending deployment. Do not substitute a standalone public-benchmark eval for the recipe's own Stage 3 evaluation.
9. For long-running SDG, prep, finetune, or eval work, start the process in a session-safe way and poll at human-scale intervals: roughly 60 seconds for small pilots and 120-300 seconds for larger runs.
-10. For failures, load `PITFALLS.md`, localize the failing stage, then inspect the stage config, expected inputs, output directory, and corresponding CLI wrapper or `run_uv.py`.

+## Model Profiles
+
+Default (`-c default`):
+
+- Nemotron 3 Embed is the default model family.
+- Uses `nvidia/Nemotron-3-Embed-1B-BF16` from Hugging Face.
+- Stage 0 uses Data Designer's built-in endpoint or the generic
+ `NVIDIA_API_BASE_URL` override and
+ `nvidia/nemotron-3-ultra-550b-a55b` for generation and judging.
+- Model-dependent outputs are isolated below `output/embed/nemotron-3-1b/`.
+- Every stage derives its paths from `artifact_root`; a pipeline-wide override
+ relocates the complete artifact chain without changing model identity.
+- Stage 4 has `enabled=false`; it returns a skipped result without loading or
+ converting the checkpoint.
+- Stage 5 can use a compatible NIM image configured by
+ `NEMOTRON3_EMBED_NIM_IMAGE` with `backend=nim`, mounting the Stage 2
+ consolidated checkpoint read-only at `/model` with `NIM_ENGINE_MODEL_PATH=/model`.
+ Or use the checked-in `nvcr.io/nvidia/vllm:26.06-py3` image with
+ `backend=vllm`; it mounts the same checkpoint at `/model` and detects its
+ embedding configuration automatically. Neither local-artifact path forwards
+ `NGC_API_KEY`.
+- Deploy preflight requires hidden size 2,048, 16 layers, 24 attention heads,
+ 8 key/value heads, intermediate size 6,144, and vocabulary size 131,072.
+- NIM uses a 512-token runtime limit and the default `padded-naive-fp16`
+ pipeline; override `NEMOTRON3_EMBED_NIM_PIPELINE_ID` only when the target
+ hardware supports another pipeline. vLLM derives sequence length, pooling,
+ activation, and prompts from the checkpoint.
+- The evaluator retries null/non-finite endpoint responses up to 32 times per
+ affected input. Preserve retry warnings as serving-reliability evidence.
+- Stage 2 pins Transformers 5.12.1. Stages 1 and 3 retain the supported 5.1-5.5
+ range for their checkpoint paths.
+
+Llama profile (`-c llama`):
+
+- Uses `nvidia/llama-nemotron-embed-1b-v2` for mining, training, and checkpoint
+ evaluation.
+- Retains the former `output/embed/stage*` locations.
+- Stage 4 remains enabled and uses the Llama bidirectional adapter to export
+ ONNX and optionally TensorRT.
+- Stage 5 uses `nvcr.io/nim/nvidia/llama-3.2-nv-embedqa-1b-v2:1.10.1`, mounts
+ the export at `/opt/nim/custom_model`, sets `NIM_CUSTOM_MODEL`, and
+ retains NGC credential forwarding.
+
+## Profile Selection Invariants
+
+- Run `uv run nemotron embed info` when model identity is unclear, then carry
+ the selected `-c` value and `artifact_root` through every stage.
+- Both profiles use approved NVIDIA checkpoint code with
+ `trust_remote_code=true`. Preserve each stage's checked-in Transformers
+ constraint instead of imposing one range across the full pipeline.
+- Do not copy performance overrides between profiles without a dry-run. The
+ default Nemotron 3 eval batch is `4`; the Llama profile uses `128`.
+- Preserve each profile's optimizer and checkpoint defaults. Nemotron 3 uses
+ no FlashAdamW master weights and fixed 1000-step checkpoint/validation
+ intervals; Llama uses 32-bit master weights and auto-scaled 100-step
+ intervals.

+ eval_base=false eval_finetuned=true \
+ output_dir=./output/embed/nemotron-3-1b/stage3_eval_vllm_comparison
+```
+
+This aggregate metric comparison is not proof of artifact identity. Deployment
+mount/fingerprint checks establish which local checkpoint was selected. Set

+2. Use `CUDA_VISIBLE_DEVICES=` only for local execution. For `--run` or `--batch`, set scheduler resources such as `gpus_per_node` in the selected profile and let the scheduler assign devices; use profile `env_vars` only when an executor explicitly requires an environment override.
3. Add dotlist overrides only after confirming the stage contract inputs and outputs.
4. For multi-stage `rerank run --run` or `rerank run --batch`, verify the profile provides `remote_job_dir` or `env_vars.NEMO_RUN_DIR` so stage outputs share one run directory.
5. Stop remote pipelines before `deploy`; deploy is local-only. For rerank, avoid `--stage` on `rerank run` and use the single-stage command with `--dry-run` instead.
