AMD and Stability AI have once again raised the bar in local AI image generation with the release of the world’s first Block FP16 (BF16) Stable Diffusion 3.0 Medium model, optimized for AMD Ryzen™ AI XDNA™ 2 NPUs. This cutting-edge model is now available via Amuse 3.1, developed by Tensorstack, and can be experienced on compatible Ryzen™ AI-powered laptops.
This release follows AMD’s earlier showcase at Computex 2024 of the SDXL Turbo model – the first to blend FP16 precision with INT8 efficiency. Now, the BF16 SD 3.0 Medium model builds on that innovation with superior image quality, optimized NPU acceleration, and lower system memory requirements.
Local AI Image Generation, Reinvented
Designed specifically for AMD Ryzen™ AI 300 Series and Ryzen™ AI MAX+ laptops, the new SD 3.0 Medium model delivers higher-quality image synthesis using BF16 precision, with a memory footprint of just 9GB. This makes it the first 16-bit precision model that can run locally on 24GB system RAM laptops — making high-resolution image generation more accessible than ever before.
Key Hardware Requirements:
- AMD Ryzen™ AI 300 Series or Ryzen™ AI MAX+ processor
- 50 TOPS or higher XDNA™ 2 NPU
- Minimum 24GB system RAM
How to Get Started in 3 Easy Steps:
- Download and install the latest AMD Adrenalin Driver
- Download and install Amuse 3.1 Beta from Tensorstack
- In EZ Mode, set the slider to HQ and enable XDNA™ 2 Stable Diffusion Offload
This setup unlocks the two-stage generation pipeline powered by the NPU, which first produces a 2MP image (1024×1024) and then intelligently upscales it to 4MP (2048×2048) — offering print-quality visuals on-the-go, with no subscription or internet connection required.
A Game-Changer for Creators
Whether you’re a designer, marketer, or content creator, an AMD Ryzen™ AI PC paired with Amuse 3.1 offers stock-level image generation with zero cloud dependency. Create branded visuals like soda cans, fashion shoots, or wildlife photography in seconds — and modify them easily to match your vision.
The XDNA™ 2 NPU brings powerful AI acceleration with impressive power efficiency, so you can generate images while working remotely — even at 30,000 feet.
Prompting Tips for SD 3.0 Medium
- Start prompts with image type, then structure, then details
- Keep prompt formatting consistent (spacing and punctuation matter)
- Use the same seed number, steps, and model to reproduce results
- Limit negative prompts to preserve image quality
