Both OneTrainer and SimpleTuner can train SDXL LoRAs. Here is how they compare, using each project's docs and GitHub activity.
| OneTrainer | SimpleTuner | |
|---|---|---|
| SDXL support | supported | supported |
| GitHub stars | 3243 | 2940 |
| Last commit | 2026-10-16 | 2026-10-16 |
| Latest release | none published | v4.9.3 |
| VRAM (SDXL) | low-VRAM friendly with gradient checkpointing, 8-bit optimizer, cached latents (exact GB unknown) | |
| Overview | GUI + CLI trainer with a broad model list; users report good VRAM use and speed but more settings to configure. | bghira's trainer; community describes it as more powerful (e.g. teacher-student regularization) but with a harder data loader setup. |
If you want the quickest start with a web UI, ai-toolkit is the usual community pick; choose a script-based trainer if you already use its ecosystem. We don't have a sourced head-to-head quality benchmark for SDXL between these two, so treat any "better results" claim as unknown.
