Hugging Face AI Updates: June 4, 2026

1. Reachy Mini Conversation App Adds Support for MCP Tools Hosted in Spaces

Hugging Face. The Reachy Mini conversation app now supports Model Context Protocol tools hosted in public Hugging Face Spaces, letting users extend the robot’s capabilities such as weather checking and web search without editing the app code. Remote tools run inside the Space rather than being downloaded locally, and developers can publish their own compatible tool Spaces for others to use. The feature, built with Pollen Robotics, uses a three-tier system of built-in, custom local, and remote tools governed by a tools.txt gatekeeper file. Source

2. Dharma AI Applies Direct Preference Optimization to OCR and Structured Generation

Hugging Face. The Dharma AI team published research showing that Direct Preference Optimization, a method common in chatbot alignment, can reduce failure modes in structured generation tasks such as OCR. The approach uses a model’s own degenerate outputs, such as repetition loops, as rejected examples in DPO training pairs, cutting text degeneration by an average of 59.4 percent across five model families after supervised fine-tuning, with peak reductions reaching 87.6 percent. The work is associated with the DharmaOCR project. Source
