I recently built a computer for local AI

I've found AnythingLLM is good for agent local LLMs. e.g. RAG, Web Search, orchestration, etc.

Heres a video with more info:

There's even a solid tip in the video about picking a higher quantized model for better results.

pinokio.computer looks like a cool tool, but I haven't explored it much.

ComfyUI is great for image generation. I haven't yet learned enough to make my own workflows. But if you get it, add comfy ui manager.
