diffusion models

Google DeepMind published a technical report on DiffusionGemma, a text diffusion model built by retrofitting Gemma-4-26B-A4B rather than training from scratch. The model generates 256-token blocks in parallel, reaches about 1,500 tokens per second on an Nvidia H100, and uses less than 10% of the original training budget.

Black Forest Labs has released FLUX.2 [klein], a lightweight variant of its FLUX.2 image generation model family designed for faster, more interactive use. The company frames the release as a step toward 'interactive visual intelligence,' though detailed benchmarks and pricing have not yet been disclosed.

NVIDIA released Nemotron-Labs-TwoTower-30B-A3B-Base-BF16, a block-wise diffusion language model that generates text by denoising blocks of tokens in parallel rather than sequentially. According to NVIDIA, the model achieves 2.42× the wall-clock generation throughput of its autoregressive baseline while retaining 98.7% of aggregate benchmark quality.

NVIDIA released Nemotron-Labs-Diffusion-14B, a 14-billion parameter language model that supports three decoding modes by switching attention patterns during inference. The model achieves 850 tokens per second on GB200 hardware at concurrency 1, representing a 3.3x speed-up over standard autoregressive decoding and outperforming Qwen3-8B-Eagle3 by 2.2x in self-speculation mode.

Baidu has released ERNIE-Image, an 8B parameter text-to-image generation model built on a single-stream Diffusion Transformer architecture. The model is designed for complex instruction following, text rendering, and structured image generation, and can run on consumer GPUs with 24GB VRAM.
