2x Faster Qwen3.8-Flash + GLM-5.3-Flash MTP

Run Qwen3.8-Flash-Next and GLM-5.3-Flash up to 2x faster with MTP. MTP is enabled by default, you can still disable it.
Also our new release includes 170+ training, chat, hardware, and performance improvements.

Highlights

• Smoother model loading (less errors) across local servers and connected providers.
• Safer chat edits that preserve tool cards, reply details, and conversation branches.
• New local media APIs for video, audio, and MLX-served models.
• New audio support with new models, progress tracking including: MiniMax-Music3, Higgs, MOSS and more!
• Improved multi-GPU planning, memory fitting, and split-model training.
• Ctrl+F Search now works.
• Strengthened AMD/ROCm detection, installation, and GPU compatibility.
• Upgraded MCP, Deep Research, OAuth, and agent tool reliability.

Qwen3.8-Flash + GLM-5.3-Flash

• Qwen and GLM now generate faster with MTP enabled by default.
• Use GLM tools across longer, multi-turn chats.
• Qwen automatically applies the recommended settings for thinking and non-thinking modes.

Download Qwen3.8-Flash-Next and GLM-5.3-Flash. See the Qwen guide and GLM guide for recommended settings and available GGUFs.

Faster MLX inference

• Fine-tune both large MoE models with text or images on Apple Silicon using MLX.
• Long Qwen chats now run much faster on Mac, with follow-up turns up to 30x faster.
• MLX models now use their full context size and support much longer batched generation.
• MLX releases GPU memory more cleanly between generation bursts and model switches.
• Serve MLX models through Unsloth's OpenAI-compatible API.

Audio

• Added support for MiniMax-Music3, Higgs, MOSS audio models.
• Added live progress updates while audio is being generated.
• Audio clips can now be archived and managed.
• Improved reliability with custom TTS playback fixes, Whisper pairing checks, and stronger audio testing.

Chat + tools

• Run several tool calls at once without mixing up their arguments.
• Keep tools available when chatting with images.
• Each chat keeps its MCP connection for faster tool calls.
• Local models can edit code using Codex’s apply_patch tool.
• Continue long chats with images and other media using Auto Compaction.
• Review and approve Deep Research plans before research starts.

Training + hardware

• Train larger models across multiple GPUs with automatic placement.
• AMD installs choose the best build across Windows and Linux, with BF16 on more GPUs.
• Export GLM-5.3 MLX fine-tunes to GGUF.
• Choose custom GGUF shard sizes and save locations.

API + Desktop

• Generate videos through the new OpenAI-compatible Videos API.
• Updates download in the background and install when you restart.
• Choose a custom port for LAN access.
• Generate audio with Higgs, MOSS and MiniMax models.
• Track audio generation progress and archive finished clips.
• Model downloads show clearer progress and can switch from Xet to HTTP automatically.
