AI Toolkit
OstrisAI Toolkit is a training suite for fine-tuning diffusion models, covering image, instruction-edit, video and audio model families including FLUX.1, FLUX.2, Qwen-Image and Wan. It trains LoRA and LyCORIS adapters, ships a web UI for configuring and monitoring runs, and provides recipes for running on RunPod and Modal.

README, read for the distribution and gating question: it documents manual installation and running the code from this repository ("It can be run as a GUI or CLI"), and its Ostris Cloud section asks users to rent GPUs there to support the project ("please consider using [Ostris Cloud]"), beside a Runpod affiliate link. No enterprise, pricing or licence-gated build of the software appears.
Adoption
3 low confidenceNo package registry tracks this product, so GitHub stars are the only comparable adoption signal available. A star is not a use, which limits how much the count can support and keeps confidence low.

Capability
3 medium confidenceAI Toolkit is a diffusion-specialist trainer with wide, current model coverage, but its methods are limited to LoRA and LyCORIS adapters and it has no distributed-training support. That puts it closer to single-GPU tools such as OneTrainer than to frontier-scale trainers like Megatron-LM.
