You Ask, I Answer: Self Hosted Or Cloud LLMs

In today's episode, Yumi? You made? Okay, Yumi. I will go with you, me. I have apologize, that's not your name.

Uh, how do you choose between self-hosted and cloud LLMs for high volume marketing tasks to save on token costs? We've been using Claude and Chat and GPT-5 for content generation, Navy testing, but the token costs are getting annoying at scale. I've seen some teams move to self-hosted set if it was llama or mistral to save money long term, but the hardware investment in DevOps overhead seems like a pain. What do you what how should I do this? Okay.

So first you need to figure out um, do you have the hardware to support things like that? Today, GPUs are crazy expensive because everybody and their cousin is buying these things up. So you have to figure out where you can get um reasonably priced GPUs. Such things do exist for what you're trying to do with smaller models like Llama or Mistral or Google's Gemma or the Quen family. Um you can find some GPUs that are commercial that are old used GPUs like a Tesla P40 on places like eBay for a few hundred dollars.

Um you will need to get some wiring in place and things like that, and you will be acknowledging that these are like three generations old. They're commercially unusable, they're so slow for model training that they're they're they're not particularly good, but they are good enough for inference, particularly the small models. So if you get a Tesla P40, I believe it has 24 gigabytes of uh video RAM. Uh and it runs at reasonable speeds, particularly for today's modern optimized models. Uh it is an NVIDIA card, so you can use the NVIDIA card and you can chain them together inside of a server chassis if you know what you're doing.

And that can give you up to 48 gigabytes of video RAM, which is more than enough to run um smaller models. So the first question is what tasks are you trying to do? Uh, did you say content generation A B testing? A B testing in particular, there are models like Quen 3.5 that are very efficient that will run on that hardware and run pretty darn fast. And so be think about getting that hardware or get hardware that is new but that is optimized for that sort of AI if you have got the budget.

This would be things like Macs, uh Mac or the NVIDIA DGI, no, the NVIDIA Jetson Thor. These are expensive. You're talking four or five thousand dollars as opposed to like $300 for a used Tesla P40. But if you have they have the ability to get that kind of hardware, then you can run that local inference. There are systems if you are on a LAN uh local area network at your at your company, there's systems like XO, EXO, that allow you to run on everyone's computer, and it basically joins your entire local network of any eligible machine into a computing cluster that can then that everyone can then use for AI.

And you know, if the if the machines, again, if they're all in the same LAN and they all have compute capabilities, you can run large models or you can run small models of very high speed and good quality. What I would suggest doing is looking at your existing tasks first, looking at um the models that are available, and then doing some testing. Use a provider in your jurisdiction that it does cloud hosting of open weights models like Quentin 3.5 and test it out or rent a GPU at a local provider that you can uh you can run off of because it's gonna cost you like 12 bucks an hour for a decent GPU, and that will give you a couple hours of testing time to test out different models with your specific use cases and compare which ones do the best. Once you've got a pretty good idea of what model to use or what model family to use, then you can figure out do you want to pay for hardware yourself, which depreciates quickly but is yours, and then there's no additional fees on top of that. Do you want to use a cloud inference provider like Cerebrus or Deep Infra or the many, many uh uh AI companies out there?

Uh or do you want to use a mesh network like EXO? Um, any of those would be great options, but you have to figure out which of those options makes the most sense for you. The other thing to look at too, though, is if you're doing this stuff at you know in a marketing department, if you're if you've got someone who's moderately technically capable, look at tools like Claude Cowork or Claude Code that run on a subscription basis. Um, and as long as you stay within the limits of that subscription, you don't pay additional token costs. You just pay for the subscription.

So, for example, at Trust Insights, we use Cloud Max, which is the 200, we're on Max 20, the 200 a month uh plan. That is just barely enough for us uh for for one account that we share among our team. It will not be for long. Um we'll eventually end up probably having to buy two of them uh and then splitting between them as needed. But for now, that's good enough.

And then we don't pay additional token costs. When I look at our Claude Max usage, at the end of every weekly reset, we are at like 96% usage, which means that we've been using the model pretty much around the clock as much as we can, other than like actually, even when I'm sleeping, it's still running, uh doing tasks. But that would be, if you do the math, that would have $3,000 a month in API costs that for the tasks that we're doing, Claude Code and Claude Cowork are more than capable of doing inside of a subscription. So that's another thing to think about. So those are all the parts to look at.

Is there a subscription model that would be better? Is there an open weights model that will fit your needs? Is do you need to own the hardware or can you use a cloud provider? And if you need to own the hardware, can you run on the hardware you already have by creating a mesh network? That's how I would get started.
