Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

How many GPUs do you even need to have a usable, self-hosted AI? It looks like he has 6 on his rig. Probably each costs 2k or something. That's not peanuts. I have a 12GB VRAM card. It probably can't generate anything in any meaningful amount of time. Which brings me to the question: who is this for?
Regardless, impressive what he vibe-coded there.
16GB is plenty for even older model setups. Now they've got a few models designed so you load just parts of the model onto the GPU (Mixture of Experts) and use the CPU for less referenced sections, so you get both reasonable speed and a much more complex model.
Oh nice. Does that depend on just the model or are there other requirements like CUDA or something?
Most models are going to require CUDA. There are some AMD ones out there, but it's a totally different math and setup. As for the one I mentioned, it's a pretty new idea so there are only a few out there, maybe just one (Qwen based). But I did get a 31B model to work on my 12GB, I just had to move from Ollama to llama.cpp to gain the control needed to set the parameters, and fine tune what it put on the CUDA to the max it would take. I had Claude help me along the way.
It's new enough that there aren't any good abliterated/uncensored models yet.
