Refund status unknown
Stable Diffusion XL (SDXL) was released by Stability AI in July 2023 as an open-weight model and a hosted API. The open-weight model became the foundation of the local AI image community (Automatic1111, ComfyUI, InvokeAI, all SDXL-based). The hosted API endpoint had inconsistent uptime through 2024-2025 due to Stability AI's broader funding turbulence. The hosted endpoint may have been quietly wound down; verify before relying on it.

Migration path
Recommended successor
Run SDXL locally via ComfyUI / Automatic1111 — OR migrate to Replicate / fal.ai hosted SDXL
Why this is the closest fit
The open-weight SDXL model is unchanged and freely available. Replicate and fal.ai both host SDXL as managed API services with reliable uptime, identical model outputs.
What differs from the original
Local: requires a 12GB+ GPU and ComfyUI knowledge. Replicate / fal.ai: paid per-generation but reliable. Stability's hosted endpoint was bundled with Stability Membership — switching to Replicate is à-la-carte pricing.
What this tool meant
SDXL was Stability AI's answer to DALL-E 3 — an open-weight model with output quality competitive with the leading closed models. The open release in July 2023 changed the local AI image landscape permanently (every local image tool standardized on SDXL as the base architecture). Stability AI's subsequent funding issues didn't kill SDXL itself — it killed the company's ability to run hosted infrastructure reliably. The model lives on in every local AI image workflow.

Verification note
Hosted-endpoint specific status needs verification. The open-weight SDXL model is verifiably alive and well; only the Stability-hosted API uptime is the question.
