v0.1.900-beta

We're adding support for decision models, a unified Library for docs and media, document viewer, many Apple Silicon improvements, creation of Skills, and ~4.5× faster image and video generation.

* Run and serve **Decision Models** like Laya (open-source Jev) locally
* **Skills Editor** to create, edit, and delete Skills directly in Desktop
* **ModelScope** model downloading is now here for users who can't use HF
* **Library + Document Viewer** for PDF, Word, Excel, PowerPoint, and chats.
* **Apple Silicon Improvements** including batched serving, structured outputs, and TurboQuant KV cache.
* Configure how much of a model each GPU receives.
* **Faster Image + Video Generation** with ~4.5x faster LTX-2.3 clips and 1.7–6.3x faster VAE decoding.
* New food-inspired **Themes**. Check them out!

## Library + Viewer

* View **PDF, Word, Excel, and PowerPoint** files directly in Unsloth, with links back to their source.
* Manage chats, images, videos, everything in our new **Library** tab.
* Improved attachment cards and support for reading more file formats.
* **Create your own sidebar sections** and drag sections to reorder them.

## Laya + decision models

Run **Laya decision models locally** to answer yes/no, multiple-choice, and scoring questions with probabilities.
* Enable the Decision API from **Settings > API**, with model selection and CPU or GPU controls.
* Supports the **TypeSafe SDK** through a Jev-compatible `/v1/systemone` endpoint.
* Runs natively on **MLX for Apple Silicon** when GPU is selected. [[Details](https://github.com/unslothai/unsloth/pull/11603)](https://github.com/unslothai/unsloth/pull/11603)

## Faster image + video generation

* **LTX-2.3 clips are ~4.5x faster** with distilled sampling, compile fixes, and hosted FP8 weights.
* Image and video VAE optimizations deliver **1.7–6.3x faster decoding**, with total generation speedups depending on the workflow.
* MiniMax-H3's first render is **up to a minute faster**, with **25–29 GiB lower peak memory** on A100, B200, and RTX PRO 6000.

## Apple Silicon + MLX

* **Batched serving** allows multiple replies to decode at once.
* Added **grammar-constrained structured outputs** through `response_format`.
* Added **TurboQuant KV cache** and KV cache quantization for sliding-window models such as Gemma 4.
* Improved memory estimates and automatic context sizing based on available memory.

## Skills + chat improvements

* **Create, edit, and delete Skills** from the Desktop Skills menu.
* Improved conversation recall across repeated auto compactions.
* Long-running tool calls continue even when they produce no output, with better protection against excessive output consuming memory.
* Auto-scroll or manual scroll your conversations
* Use **ModelScope** instead of Hugging Face for model downloads

## Training + inference

* Faster **block-FP8 LoRA training** and support for **LoRA on compressed-tensors W8A8 checkpoints**.
* Load **Voxtral and Qwen2-Audio** through `FastModel`.
* Export saved checkpoints from crashed or cancelled training runs.
* Important compatibility fixes for Gemma, newer TRL trainers, and FP8 on RTX 5090 and RTX PRO 6000.
