Stable Diffusion 3.5

Open-source diffusion model with full LoRA and ControlNet ecosystem support.

Stable Diffusion 3.5 is Stability AI's current-generation open-source diffusion model, released October 2024. It's the go-to for workflows needing LoRAs, ControlNet, or custom fine-tunes — the entire Stable Diffusion ecosystem runs on compatible tooling. On Oakgen, an SD 3.5 image costs about 12 credits (~$0.05).

How to use Stable Diffusion 3.5

1
Use LoRAs for brand-consistent output
Train or download a LoRA for your style. SD 3.5 supports LoRAs at 0.1–1.0 strength, and multiple LoRAs can be stacked.
2
Pair with ControlNet for precise layouts
Use ControlNet to condition on pose skeletons, depth maps, or canny edges — the most reliable way to get repeatable compositions.

Compared to other models

vs. flux-pro-1-1 — ecosystem

SD 3.5 has a richer community ecosystem — LoRAs, ControlNets, fine-tunes. FLUX Pro 1.1 produces higher-quality single-shot output but lacks the same community tooling. Pick SD 3.5 for custom styles, FLUX Pro for hands-off quality.
