+```
+
+`ai-hub upload` runs the four Workbench upload steps in order: quantize, compile, validate, and profile. Use `--from-step compile`, `--from-step validate`, or `--from-step profile` to resume from saved local state after a completed earlier step.
+
+Resume behavior:
+
+```text
+--from-step quantize  Run quantize, compile, validate, and profile.
+--from-step compile   Skip quantize; compile the last quantized model unless an explicit source is passed.
+--from-step validate  Skip quantize and compile; validate the last compiled model.
+--from-step profile   Skip quantize, compile, and validate; profile the last compiled model.
+```
+
+When a step runs in the current command, `upload` passes its returned model ID directly to the next step. When a step is skipped, the next step resolves the needed model ID from `.qc-cli.json`. This avoids re-running earlier AI Hub jobs when you only need to continue from a later step.
+
+`ai-hub compile` resolves model sources in this order: `--model-id`, explicit source options (`--onnx-path`, `--model-s3-uri`, `--from-job`), last quantized model from state, then the last training job from local state. `ai-hub download` is separate because downloading the optimized artifact is outside the four-step Workbench upload loop.
+
+AI Hub authentication currently uses the local `qai-hub` SDK configuration. A planned follow-up is to support AWS Systems Manager Parameter Store `SecureString` for team-managed tokens, where `config.yaml` stores only a parameter name such as `/qc-cli/aihub/token`, AWS KMS encrypts the token at rest, and the CLI retrieves it at runtime with `ssm:GetParameter` plus `kms:Decrypt` permissions.
+
+## Model lifecycle
+
+The CLI uses neutral experiment naming for trained artifacts and reserves release terminology for an explicit promotion step.
+
+Current behavior:
+
+1. `qc-cli train start` submits a SageMaker training job.
+2. `qc-cli train status` finalizes the MLflow run after the job reaches a terminal state.
+3. If the job completed and `mlflow.register_trained_models` is enabled, the SageMaker `model.tar.gz` is registered as a new MLflow model version with:
+   - `qc_cli.stage=experiment`
+   - `qc_cli.artifact_kind=trained_source`
+   - `qc_cli.source=sagemaker`
+4. The MLflow alias `experiment-latest` points at the most recently registered experiment version.
+5. AI Hub upload commands create deployable derived artifacts from a trained-source experiment or local ONNX model.
+
+Future release aliases such as `v1` or `production` can point at a selected deployable artifact.
+
+Example future metadata:
+
+```text
+qc-cli-model version 12
+qc_cli.stage=experiment
+qc_cli.artifact_kind=trained_source
+qc_cli.source=sagemaker
+
+qc-cli-model-aihub version 3
+qc_cli.stage=ai_hub_compiled
+qc_cli.artifact_kind=deployable
+qc_cli.parent_registered_model_name=qc-cli-model
+qc_cli.parent_model_version=12
+qc_cli.runtime=tflite
+qc_cli.quantization=int8
+qc_cli.target_device=Samsung Galaxy S25
+```
+
+In that flow, `experiment-latest` remains a training convenience alias. Release selection is a separate promotion decision based on the derived artifact, not on the experiment name.

+# Qualcomm AI Hub Example
+
+This example takes the ONNX model produced by the SageMaker training example and runs the Qualcomm AI Hub upload workflow:
+
+1. Quantize
+2. Compile
+3. Validate
+4. Profile
+5. Download the compiled artifact
+
+## Prerequisites
+
+Run the training example first and wait for it to complete:
+
+```bash
+bash examples/training/run_training.sh --config config.yaml --wait
+```
+
+If the dataset is already uploaded to S3, use:
+
+```bash
+bash examples/training/run_training.sh --config config.yaml --skip-upload --wait
+```
+
+The training artifact must contain a static-shape `model.onnx`. The training example exports an input named `input` with shape `1x3x160x160`.
+
+Your `config.yaml` must include AI Hub settings:
+
+```yaml
+aihub:
+  device:
+    name: Samsung Galaxy S25 (Family)
+  target_runtime: tflite
+  input_specs:
+    input: [[1, 3, 160, 160], float32]
+  output_dir: build/qai-hub
+```
+
+You also need local Qualcomm AI Hub SDK authentication configured.
+
+## Prepare Inputs
+
+AI Hub does not consume the raw JPG training images directly. It needs NumPy tensors that match the ONNX model input shape and preprocessing.
+
+Generate calibration and validation inputs:
+
+```bash
+uv run python examples/ai-hub/prepare_inputs.py
+```
+
+This writes:
+
+```text
+examples/training/data/aihub_calibration/*.npy
+examples/training/data/inputs.npz
+```
+
+The script applies the same image preprocessing used by the training example:
+
+- resize to `160x160`
+- convert to channel-first `1x3x160x160`
+- normalize with ImageNet mean and standard deviation
+
+Useful options:
+
+```bash
+uv run python examples/ai-hub/prepare_inputs.py \
+  --dataset-dir examples/training/data/flower_photos_sagemaker \
+  --calibration-dir examples/training/data/aihub_calibration \
+  --input-file examples/training/data/inputs.npz \
+  --samples 16
+```
+
+## Run AI Hub
+
+After training completes and inputs are prepared:
+
+```bash
+bash examples/ai-hub/run_ai_hub.sh --config config.yaml
+```
+
+By default, the script uses the last SageMaker training job recorded in `.qc-cli.json`. It downloads that job's `model.tar.gz`, extracts `model.onnx`, runs the AI Hub workflow, and downloads the compiled artifact.
+
+To use a specific training job:
+
+```bash
+bash examples/ai-hub/run_ai_hub.sh \
+  --config config.yaml \
+  --from-job qc-cli-YYYYMMDD-HHMMSS
+```
+
+To resume from a later Workbench step:
+
+```bash
+bash examples/ai-hub/run_ai_hub.sh \
+  --config config.yaml \
+  --from-step validate
+```
+
+To skip downloading the compiled artifact:
+
+```bash
+bash examples/ai-hub/run_ai_hub.sh \
+  --config config.yaml \
+  --skip-download
+```
+
+## Troubleshooting
+
+If AI Hub reports dynamic input shapes, rerun training with the current training source. AI Hub quantization requires the exported ONNX model to use static input shapes.
+
+If `run_ai_hub.sh` reports missing calibration or input files, run:
+
+```bash
+uv run python examples/ai-hub/prepare_inputs.py
+```
+
+If validation fails with a missing input name, make sure `config.yaml` and the generated `.npz` both use `input` as the input name.
