v0.1.464-beta

We've merged over 150 PRs this week so lots of new updates, a new model Hub and look! Ensure you install the latest `v0.1.464-beta` or `2026.6.7`. [DiffusionGemma](https://unsloth.ai/docs/models/diffusiongemma), [Gemma 4 MTP](https://unsloth.ai/docs/models/mtp) and **[MiniMax-M3](https://unsloth.ai/docs/models/minimax-m3)** are all now supported.

### DiffusionGemma + Gemma 4 MTP + Audio
- Run and train [DiffusionGemma](https://unsloth.ai/docs/models/diffusiongemma) via [Unsloth Studio](https://unsloth.ai/docs/new/studio). Install the latest `v0.1.462-beta` if DiffusionGemma wasn't previously working.
- [Gemma 4 MTP](https://unsloth.ai/docs/models/mtp) is here! Run [Gemma 4](https://unsloth.ai/docs/models/gemma-4) around 2x faster with MTP - MTP is auto enabled in Unsloth Studio.
- [Audio chat](https://unsloth.ai/docs/new/studio/chat) is now supported for Gemma 4 (`wav`, `mp3`, `m4a`,`flac`, `webm`).
- Preserve Thinking added to Gemma 4.

### Hub + Download Manager (Experimental)
- Added a new **Hub** page for browsing, downloading, and managing Hugging Face models and datasets.
- Unsloth can now detect models and datasets already on your machine and show them alongside downloaded assets.
- Downloaded [GGUF models](https://unsloth.ai/docs/get-started/unsloth-model-catalog) now have direct **Run / New Chat** actions.

### Chat with Files / RAG (Experimental)
- Added **[Chat with Files](https://unsloth.ai/docs/new/studio/chat)** in Studio, letting you ask questions over your own documents and knowledge bases.
- Supports hybrid search, citations, PDF previews, per-thread documents, and a built-in `search_knowledge_base` tool.

### New Update Button + Hardware Support
- Unsloth now uses fresh, up-to-date [llama.cpp prebuilts](https://unsloth.ai/docs/new/changelog) across CUDA, ROCm, Windows, Linux, and macOS.
- Added an in-app **Update llama.cpp** button so users can update the local backend without reinstalling Studio.
- Improved Windows / WSL AMD support, [Strix Halo ROCm support](https://unsloth.ai/docs/get-started/install/amd), [Blackwell CUDA selection](https://unsloth.ai/docs/blog/fine-tuning-llms-with-blackwell-rtx-50-series-and-unsloth), and clearer installer messages.

### Local Chat, Tools & API Compatibility
- Local [tool calling](https://unsloth.ai/docs/basics/tool-calling-guide-for-local-llms) is more reliable, with better ordering of tool cards, fewer duplicate tool loops, and support for tool use with GGUF vision models.
- Improved [OpenAI-compatible API](https://unsloth.ai/docs/basics/inference-and-deployment/llama-server-and-openai-endpoint) and Anthropic-compatible API behavior for local Studio servers, including better errors, token usage, stop reasons, and [Claude Code compatibility](https://unsloth.ai/docs/basics/claude-code).

### Tool Calling, MCP, Encrypted Cloudflare Tunnels
- Bypass Permissions, Tool Call Permissions (Approve, Always Approve, Deny)
- 50% to 90% less tool call nudging issues without any accuracy loss
- MCP, Artifacts are now select-able
- Tensor parallelism is now enabled for GGUFs - get +30% throughput!
- Cloudflare HTTPS free tunnels is now added allowing for end to end encrypted studios!

### Training & General Fixes
- Improved [MLX support](https://unsloth.ai/docs/new/studio/install) with better model labels, generation speed stats, and fixes for [VLM training](https://unsloth.ai/docs/basics/vision-fine-tuning).
- Fixed several [training](https://unsloth.ai/docs/get-started/fine-tuning-llms-guide) and [dataset](https://unsloth.ai/docs/get-started/fine-tuning-llms-guide/datasets-guide) edge cases, including non-writable Hugging Face caches and custom dataset mappings.
- Added many UI polish fixes across chat, menus, model picker, dark mode, import/export, and settings.
