Hugging Face Summer Update: Hub growth, Spaces beta, TensorBoard, and model-card metrics

AI Impact Summary

Hugging Face reports Hub growth to over 16,000 public model repos and introduces Spaces (beta) to deploy demos via Gradio or Streamlit with secret management and GitHub repo integration. TensorBoard integration now auto-launches for repos with traces, simplifying visualization for both public and private models. The update also adds model-card evaluation metrics linked to Papers With Code, plus new widgets and ONNX export support in transformers.onnx, tightening the end-to-end path from training to benchmarking to deployment. Together, these changes accelerate model sharing, evaluation, and interactive demos across the Hub and Transformers ecosystem.
