-## Publishing to HuggingFace
-
-Trained models can be published to HuggingFace Hub for community use:
-
-```bash
-# Publish (uses API key from GCloud Secrets)
-bash scripts/publish-huggingface.sh --version v0.5.4
-
-# Or with Python
-python scripts/publish-huggingface.py --version v0.5.4
-
-# Dry run (preview without uploading)
-bash scripts/publish-huggingface.sh --dry-run
-```
-
-The HuggingFace API key is stored in Google Cloud Secrets (`HUGGINGFACE_API_KEY` in project `cognitum-20260110`). Alternatively, set the `SEED_TOKEN` environment variable directly.
-
-Published artifacts include: SafeTensors model, quantized variants (2/4/8-bit), LoRA adapters, training metrics, and a beginner-friendly model card.
