As AI consultants based in Rosenheim, Germany, we recommend Stability AI for enterprises seeking high-quality image, video, and audio generation with open weights and full data control. With Stable Diffusion 3.5 and Stable Audio 3.0 (May 2026), Stability AI offers a broad ecosystem of open generation models for image, video, and audio. This overview reflects the state as of October 2026.
From StableLM to Stable Diffusion 3.5
Stability AI underwent a turbulent period in 2023/2024 (founder resignation, funding difficulties) but has since stabilized. Since June 2024, CEO Prem Akkaraju (formerly Weta Digital) leads the company with fresh capital (~$80M). In November 2025, Stability AI largely prevailed in the copyright lawsuit with Getty Images in the High Court of England and Wales (with limited trademark findings against it). On August 25, 2026, Stability AI announced a Series B funding round of $76M (bringing total funding to $232M), with investors including Electronic Arts, Sony Music Group, Universal Music Group, and Warner Music Group. The company focuses on its core competency: generative models for image, video, and audio. The StableLM language models are no longer actively developed.
Why Stability AI for Enterprises?
- Open Weights: Models freely available on Hugging Face
- Self-Hosting for EU Data Residency: Since the cloud offerings (AWS Bedrock, Azure) do not, per current documentation, offer a reliable EU region (see below), self-hosting the open weights is the most reliable path to EU data processing
- Broad Ecosystem: Thousands of community extensions and LoRA models
- Multimodal: Image, video, and audio from a single provider
- GDPR-Compliant: Full self-hosting possible
Stable Diffusion 3.5 – The Flagship
Stable Diffusion 3.5 (October 2024) represents a significant quality leap over previous versions. The new architecture is based on a Diffusion Transformer (DiT) with a dual text encoder (CLIP and T5).
Three Variants for Different Requirements
| Variant | Parameters | VRAM | Strength |
|---|---|---|---|
| SD 3.5 Large | 8B | ~24 GB | Highest quality |
| SD 3.5 Medium | 2.6B | ~10 GB | Balanced profile |
| SD 3.5 Large Turbo | 8B | ~24 GB | Fast inference |
SD 3.5 Large delivers high prompt adherence and image quality according to Stability AI. The Turbo variant is suited for applications with real-time requirements, while Medium offers a good compromise between quality and resource demands.
Beyond Images: Video and Audio
Stable Video Diffusion 2.0
Stable Video Diffusion 2.0 (2025) enables the generation of short video clips from text prompts or single images. The technology is suitable for product animations, social media content, and creative prototypes.
Stable Audio 3.0
On May 20, 2026, Stability AI released Stable Audio 3.0 – a family of four models (Small SFX and Small at 459M each, Medium at 1.4B, and Large at 2.7B parameters). Medium and Large can generate compositions up to 6 minutes and 20 seconds long while maintaining musical structure and melody – more than double the length of the predecessor Stable Audio 2.0.
Small SFX, Small, and Medium are available as open weights on Hugging Face and can be self-hosted in a GDPR-compliant manner. The Large variant is exclusively accessible through the Stability AI API, partner fal.ai, or an enterprise license. Important for businesses: companies with more than $1M in annual revenue require an enterprise license for commercial use. All models were trained on fully licensed data (AudioSparx library and Creative Commons recordings from Freesound) – relevant for copyright assessment.
StableLM – Language Model Status
The StableLM language models (StableLM 2 1.6B, StableLM Zephyr 3B) have reached deprecated status. They are no longer actively maintained and are not recommended for production applications. For language models, we recommend more capable alternatives such as Meta Llama or Microsoft Phi.
GDPR-Compliant Deployment in the EU
Caution is warranted with the cloud offerings: per the current AWS region table, Stability AI models on Amazon Bedrock are available only in US regions (SD3.5 Large, Stable Image Ultra, and Stable Image Core only in us-west-2/Oregon; the editing tools additionally in us-east-1/us-east-2) - there is no EU region there, not even via Geo or Global routing. Availability in Frankfurt (eu-central-1) cannot be substantiated.
On Microsoft Foundry / Azure AI Foundry, SD3.5 Large, Stable Image Ultra, and Stable Image Core are listed in the model catalog, but only as a Managed Compute deployment - you provision your own GPU instance in a workspace of your choice; there is no serverless pay-as-you-go option as with other Foundry models. Whether an EU region (e.g. West Europe, Germany West Central) is actually usable depends on local GPU SKU availability and should be checked case by case.
The most reliable path to genuine EU data residency is therefore:
- Self-Hosting: Download open weights from Hugging Face and run on your own (EU) infrastructure
Through open model weights, enterprises retain full control over their data – a decisive advantage for GDPR compliance, especially since the major hyperscalers currently do not offer a reliable EU region for Stability AI models.
Integration with CompanyGPT
Stability AI models can be integrated in CompanyGPT as a self-hosted option for image generation – ideal for marketing teams that want to create visual assets internally and in compliance with data protection regulations.
Our Recommendation
Stable Diffusion 3.5 Large is the top choice for enterprises that need high-quality image generation with full data control. For resource-constrained environments, SD 3.5 Medium offers a compelling alternative.
Those who additionally need video or audio generation will find a growing ecosystem with Stable Video Diffusion 2.0 and Stable Audio 3.0 (May 2026) – including open-weights options for GDPR-compliant self-hosting. For pure language model applications, however, we recommend alternatives like Meta Llama or Mistral.
