Hi there, If I'm looking to use LLM AI in a similar way like Stable Diffusion, i.e. running it on my own PC using pre-trained models (checkpoints?) - where would I start?

If I would want to have access to it on my mobile devices - is this a possibility?

If I would then later want to create workflows using these AI tools - say use the LLM to generate prompts and automatically run them on Stable Diffusion - is this a possibility?

I'm consistently frustrated with ChatGPT seemingly not beeing able to remember a chat history past a certain point. Would a self-run model be better in that regard (i.e. will I be able to reference somethin in a chat thread that happened 2 weeks ago?)

Are there tools that would allow cross-thread referencing?

I have no expert knowledge whatsoever, but I don't shy away from spending hours learning new staff. Will I be able to take steps working towards my own personal AI assistant? Or would this be way out of scope for a hobbyist?

Depends on your hardware and how far you're willing to go. For serious development I think you need at least 12-16 GB of VRAM, but there's still some things you can do with ~8. If you just have a cpu, you can still test some models but generation will be slow.

I'd recommend trying out the oogabooga webui. This should work with quite a few models on hugging face. Hopefully I don't get in trouble for recommending a subreddit but r/localllama has a lot of other great resources and us a very active community. They're doing exactly what you want.

As far as your other questions...

Accessing it on your phone is going to be tricky. You would most likely want to host it somewhere but I'm not sure how easy that is for someone without a bit of software background. Maybe there is a good service for this, huggingface might offer something.
Cross thread referencing is an interesting idea. I think you would need to create a log store of all your conversations and then embed those into a a vector store (like milvus or weaviate or qdrant). This is a little tricky since you have to decide how to chunk your conversations, but it is doable. The next step is somewhat open ended. You could always query your vector store with any questions that you are already sending your model, and then pass any hits to the model along with your original question. Alternatively, you could tell the model to check for other conversations and trigger a function call to do this on command. A good starting point might be this example, which makes references to a hardware manual in a Q&A style chatbot.
Using an LLM with stable diffusion: not especially sure what you are hoping to get out of this. Maybe to reduce boilerplate prompt writing? But yes you can finetune a model to handle this and then have the model execute a function that calls stable diffusion and returns the results. I am pretty sure langchain provides a framework for this. Langchain is almost certainly a tool you will want to become familiar with.

Thank you for the input! I recently upgraded my PC to be able to handle Stable Diffusion, and I got 12GB of VRAM to work with at the moment. I also have recently started to self-host some applications on a VPS, so some basics are there.

As for what I'd like to do with Stable Diffusion: One of my hobbies is storytelling and worldbuilding. I would like to (one day) be able to work on a story with a LLM and then prompt it: "now give me a drawing of the character we just introduced to the story" and the LLM would automagically rope in Stable Diffusion and produce a workable drawing with it. I think that this is probably beyond the capability of the current tools, but this is what I would like to achieve. I will definitely look into langchain to see what I can do with it.

That's also where the questions about context length and cross thread referencing come from. I did some work with ChatGPT and am amazed at how good a tool it is to "brainstorm with myself" in developing stories. However, it does not remember the story bits I've been working on 2 hours ago, which kinda bummed me out .. :)
