Any good self-hosted LLM for software development?
Any good self-hosted LLM for software development?
Hi,
I'm looking for something that could generate code and provide technical assistance on a level similar to ChatGPT4 or at least 3.5. I'm generally satisfied with it, but for privacy and security reasons I can't share some details and code listings with OpenAI. Hence, I'm looking for a self-hosted alternative.
Any recommendations? If nothing specific comes to mind, what parameters should I look at in my search? I've never worked with LLMs yet and there are so many of them. I just know that I could use oobabooga/text-generation-webui to access a model in a friendly way.
Thanks in advance.
You're viewing a single thread.
Specifically on what LLM to use, I've been meaning to try Starcoder, but can't vouch for how good it is. In general I've found Vicuna-13B pretty good at generating code.
As for general recommendations, I'd say the main determinant will be if you can afford the hardware requirements to locally host - I presume you're familiar with the fact that you'll (usually) need roughly 2x the number of parameters in VRAM (e.g. 7B parameters means 14GB of VRAM). Techniques like quantization to 8-bits halve the requirement, with the more extreme 4-bit quantization halving them again (at the expense of generation quality).
And if you don't have enough VRAM, there's always llama.cpp - I think that list of supported models is outdated, and it supports way more than those.
On the "what software to use for self-hosting" I've quite liked FastChat, they even have a way to run an OpenAI API compatible server, which will be useful if your tools expect OpenAI.
Hope this is helpful!
Thanks you for the information and suggestions!
