-## Upload Model to Qualcomm Workbench
+Useful options:
-
-The model can be uploaded to Qualcomm Workbench using:
 
 ```bash
-qc-cli ai-hub upload examples/training/data/aihub_calibration examples/training/data/inputs.npz
+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
 ```
 
-The first argument is the calibration path for the model and the second argument is the input file, both of which were created by the `prepare_inputs.py` script. For more details, add `--help` after the `upload` command.
+## Run AI Hub
 
-The `upload` command runs the following commands in order:
+After training completes and inputs are prepared:
-1. `qc-cli ai-hub quantize`
-2. `qc-cli ai-hub compile`
-3. `qc-cli ai-hub validate`
-4. `qc-cli ai-hub profile`
 
-Finally the user can download the model from AI Workbench using the command
 ```bash
-qc-cli ai-hub download
+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.
