It kind of sucks that the AI/ML community seems to exclusively use twitter, at least people interested in the type of work I do.

HiDream LoRA fine tuning is now live on AI-Toolkit CLI and in the GUI. It currently requires a minimum of 36 GB of VRAM. Working on getting that down.

AI generated nonsense music video with a LoRA I trained of myself (Wan2.1 14B). Prompts for video, video, and music is all AI generated. I edited it myself, that is the last step to automate for a fully automated AI slop machine.

Made some long overdue ComfyUI nodes for Flex.1-alpha.
A node to set guidance or bypass it for true CFG.
LoRA loaders that automatically prune Flux LoRAs to work with Flex. They won't work perfect, but it should be decent for most use cases.

Wan 2.1 14B is amazing quality, but it is slow. The 1.3B version is extremely fast, and finetunes well. I trained a quick LoRA on it of myself for 1k steps. This is the most fun I have had messing with generative AI since the early SD1 days. Infinite personalized slop machine.

First training sample montage of training a LoRA on Wan2.1 1.3B with AI Toolkit. Cruella.
Still have to test my LoRA format to see if I can get it to load anywhere or if I need to modify it. Initial release will likely only support training on stills for now.

Running a training test for training a redux adapter for Flex.1-alpha using siglip2-so400m-patch16-512. It is learning it remarkably fast. The 512 resolution should help with detail and texture vs the 384 v1 version.

There is no joke funnier than OpenAI clutching their pearls because they suspect someone may have used their data to train a LLM without their permission.

The upstart Chinese AI maker might have "distilled" OpenAI's models, violating terms of service, OpenAI said.

Testing LoRA training for a new 8B model I have been cooking. Marty McFly and Pixar style LoRA training samples here.
It is based on a pruned version of OpenFlux that has been continuously trained. I also trained a guidance embedding for it among other cool things.

Has anyone had any luck converting FLUX LoRAs to SVDquant format? I have been trying to reverse engineer the process but keep hitting roadblocks.

A common question nowadays: Which is better, diffusion or flow matching? 🤔
Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably.

Seriously, why is my Amazon Echo still dumber than a box of rocks? Have any of the home assistants evolved past the technology from 10 years ago? Is someone going to do something about this or do I need to?

Testing training just an embedding that attaches like the Flux Redux output does. This is with 42 tokens doing cruella. It seems incapable of learning identity concatenating the embedding this way, leading me to think a face redux (which I am also training), may not be possible.

Why don’t people want AI models to be trained on their ideals and views. AI models WILL develop a bias based on their training data. I would prefer the biases of the people on this platform to be trained into them. Otherwise, future AI will just be a crypto bro. Please support scraping public data.
