Paper: Unlocking Lossless Speedups in LLMs via Discrete Diffusion Project Page: https://s-sahoo.github.io/uno/ Code: https://github.com/ifm-ai/uno

We present K2-Horizon-7B-Uno, a diffusion-augmented LLM with two pathways in a unified architecture:

—The AR pathway uses the AR weights of the K2-Horizon-7B model.
—The diffusion pathway augments these weights with LoRA-based diffusion adapters.

[image]

This repository contains the adapter only. The base-model weights are hosted separately in **IFM/K2-Horizon-7B**.

Code

Selected evaluation scripts are available in **scripts/k2_horizon**. The full evaluation suite will be released soon.

Evaluation results

The main number is the benchmark score and the subscript is TPF. Bold marks the best score in each row. -- and N/A denote unavailable results.
