## Qwen3.8-Flash-Next

Qwen3.8-Flash-Next is a new 125B multimodal reasoning model and an early preview of Qwen4's architecture.

- The 1-bit Unsloth Dynamic GGUF runs on 75GB RAM or unified memory.
- It's 79% smaller than BF16 while retaining 80% top-1 accuracy.
- Chat with text and images using up to 262K context.
- Switch between None, Low, Medium and Extra High reasoning.
- Preserved Thinking keeps reasoning consistent across longer chats.

## GLM-5.3-Flash

GLM-5.3-Flash is Z.ai's new 320B multimodal model, with only 18B parameters active at a time.

- Run the 1-bit model on 102GB of combined RAM + VRAM.
- Chat with text, images and long documents using up to 1M context.
- Switch between Low, High and Max reasoning.
- Stronger coding, agent and vision performance than GLM-5.2.
- Recommended settings are applied automatically in Unsloth.

## Chat + tools

- Local chats resume after a disconnect instead of losing the reply.

- Model settings stay saved when switching chats.
- Search and download embedding models directly from Hugging Face.
- Text-to-speech models only load when you actually use them.

## Desktop + reliability

- Linux voice recording fixed.
- NVIDIA + Wayland interface freezes fixed.
- AMD model loading crashes fixed.
