unslothai/unsloth v0.1.917-beta on GitHub

Qwen3.8-27B is here with Dynamic v3.1 GGUFs, ready to run locally with Unsloth. This release also brings major performance improvements, smoother Glass rendering, revamped code blocks and Thinking UI, HTML/PDF chat exports, and new image generation and coding agent features.

Highlights

New Qwen3.8-27B Dynamic v3.1 GGUFs.
Faster chats: Major performance improvements to streaming, scrolling, menus and dialogs, especially in long conversations.
Smoother Glass: Reduced lag while typing, scrolling and generating.
Revamped code blocks and Thinking: Independently scrolling, expandable panels with improved syntax highlighting.
HTML and PDF exports: Export chats directly from the chat menu.
Image queue: Queue upcoming image generations while another is rendering.
Claude Code and Codex on MLX: Run coding agents with MLX models through unsloth start.

Chat & UI

Streaming performance no longer degrades as conversations grow.
Smoother scrolling with background images, with or without Glass.
Faster menus, dialogs and browser pane loading.
Read aloud starts after the first sentence instead of waiting for the entire response.
Chat preferences, time format and spell check now sync with your account.

Images & Video

FLUX.2 and FLUX.3 use 36–43% less VRAM during image decoding at the same speed.
Queue image generations from the Images page or API.
INT8 and FP8 image models now load on older NVIDIA GPUs, including T4.
Fixed black image outputs with FLUX.3.
LTX-2.5 FP8 now runs on 24 GB GPUs.
Cosmos3-Nano can continue video clips from their first or last frames.

Coding Agents & API

Run Claude Code and Codex with MLX models on Mac using unsloth start.
New Unsloth MCP preset lets coding agents access Unsloth tools.
Claude API models without an explicit token limit no longer stop at 1,024 tokens.
MLX models now return a proper context-length error instead of an empty response.

Training

model.generate() is now 2–8x faster on T4 GPUs by default across FastModel models.
Video columns are now correctly supported when training vision models.
Ulysses context parallelism now supports Kimi-Linear, DeepSeek, MiniMax and Gemma 4 text models.
