Bakgrunn

Om Stability AI

Grunnlagt 2019 · London, UK

Stability AI was founded in 2019 by Emad Mostaque (CEO until March 2024) and is headquartered in London. The company sponsored and released the original Stable Diffusion 1.4/1.5/2.x (2022) in partnership with CompVis (LMU Munich, Robin Rombach and Patrick Esser), Runway and LAION. Stable Diffusion XL (SDXL) was released in July 2023 by Stability AI as a successor to SD 1.5/2.1 and was widely adopted by the open-source community as the de-facto open base model for fine-tuning and downstream pipelines until FLUX.1 and SD 3.5 arrived in 2024.

Arkitektur

Latent diffusion U-Net with two text encoders and optional refiner

Stable Diffusion XL (SDXL) is a 2023 latent diffusion model from Stability AI, described in 'SDXL: Improving Latent Diffusion Models for High-Resolution Image Synthesis' (Podell et al. 2023). The architecture is a refined latent-diffusion U-Net operating in the latent space of a learned 8x VAE. Key changes over SD 1.5 include: (1) a larger U-Net backbone (~3.5B parameters, ~3x larger than SD 1.5), (2) two parallel text encoders concatenating CLIP ViT-L and OpenCLIP ViT-bigG features for stronger prompt adherence, (3) conditioning on the original image resolution and crop coordinates to fix the resolution and cropping artefacts of SD 1.5, (4) training natively at 1024x1024 instead of 512x512, and (5) an optional 6.6B-parameter refiner model that performs a final 5-step denoising pass to add high-frequency detail. SDXL became the dominant open base model for fine-tuning between mid-2023 and late 2024, spawning huge ecosystems including IP-Adapter, AnimateDiff, ControlNet-XL, T2I-Adapter and tens of thousands of community LoRAs.

Parametere: ~3.5B base U-Net + 6.6B refiner = ~10.1B total
Kontekst: 75 tokens

Evner

Native 1024x1024 generation
Two text encoders (CLIP-L + OpenCLIP-G) for strong prompts
Optional refiner for high-frequency detail
Open weights under CreativeML Open RAIL++-M license
Massive ecosystem: ControlNet-XL, IP-Adapter, AnimateDiff, LoRAs
Strong fine-tuning base for art styles and brand models
Runs on consumer GPUs (8-12GB VRAM with quantisation)
Best for: fine-tuning base, ControlNet pipelines, community LoRAs, on-prem deployments, education.

Trening og lisens

Pretrained on a large subset of LAION-5B and additional Stability AI-curated data. Conditioned on resolution and crop coordinates to mitigate aspect-ratio artefacts.

Lisens: CreativeML Open RAIL++-M license — open weights with usage restrictions (no NCII, CSAM, etc.). Commercial use permitted with these restrictions.

Sikkerhetstesting: Stability AI applied baseline content filters and training data filtering. The model ships without an integrated safety classifier and operators must add their own moderation.

Kjente begrensninger

Older architecture — outperformed by FLUX.1 and SD 3.5 Large
Hands, text and complex anatomy imperfect
Default text encoder limited to 75 tokens
Open weights have no built-in safety filter
