Download the model in background. Serve the client with an LLM vendor API just for the first requests, or even using that same local LLM installed on your own servers (likely cheaper). By doing so, in the long run the inference cost is near-zero and allows to use LLMs in otherwise impossible business models (like freemium).
Exactly. Why does this not exist yet?
I thought llamafile was supposed to be the solution to "too hard to work with"? https://github.com/Mozilla-Ocho/llamafile
I thought it's "docker model" (and OCI artifacts).
Yikes what's the bar for dead simple these days? Even my totally non-technical gamer friends are messing around with ollama because I just have to give them one command to get any of the popular LLMs up and running. Now of course "non technical" here is still a pc gamer that's had to fix drivers once or twice and messaged me to ask "hey how do i into LLM, Mr. AI knower", but I don't think twice these days about showi…
By "too hard" I do not mean getting started with them to run inference on a prompt. Ollama especially makes that quite easy. But as an application developer, I feel these platforms are too hard to build around. The main issues being: getting the correct small enough task specific model and how long it takes to download these models for the end user.
As a developer the amount of effort I'm likely to spend on the infra side of getting the model onto the user's computer and getting it running is now FAR FAR below the amount of time I'll spend developing the app itself or getting together a dataset to tune the model I want etc. Inference is solved enough. "getting the correct small enough model" is something that I would spend the day or two thinking about/testing when building something regardless. It's not hard to check how much VRAM someone has and get the right model, the decision tree for that will have like 4 branches. It's just so little effort compared to everything else you're going to have to do to deliver something of value to someone. Especially in the set of users that have a good reason to run locally.
Weird to give MacBook Pro specs and omit RAM. Or did I miss it somehow? That's one of the most important factors.

Using a 7B model on a M2 Max also isn’t quite the most impressive way to locally run an LLM. Why not use QwQ-32 and let it give some commercial non-reasoning models a run for their money?
LM Studio seems pretty good at making local models easier to use
I'm genuinely afraid its going to do telemetry one day. I'm sure someone is watching their internet traffic, but I don't. I take the risk now, but I ask questions about myself, relationships, conversations, etc... Stuff I don't exactly want Microsoft/ChatGPT to have.

Basically you let a very small model speculate on the next few tokens, and the large model then blesses/rejects those predictions. Depending on how well the small model performs, you get massive speedups that way.
The small model has to be as close to the big model as possible - I tried this with models from different vendors and it slowed generation down by x3 or so. So, you need to use a small Qwen 2.5 with a big Qwen 2.5, etc
- first of all local inference can never beat cloud inference for the very simple reason that costs go down with batching. it took me two years to actually understand what batching is - the LLM tensors flowing through transformer layers has a dimension designed specifically for processing data in parallel. so no matter if you process a 1 sequence or 128 sequences the costs are the same. i've read very few articles overstating this, so bear in mind - this is the primary stopper for competing local inference with cloud inference.
- second, and this is not a light one to take - LLM-assisted text2sql is not trivial, not at all. you may think it is, you may expect cutting-edge models to do it right, but there are ...plenty of reasons models fail so badly at this seemingly trivial task. you may start with arbitrary article such as https://arxiv.org/pdf/2408.14717 and dig the references, sooner or later you will stumble on one of dozens overview papers by mostly Chinese researchers (such as https://arxiv.org/abs/2407.10956) where overview of approaches is summarized. Caution: you may feel both inspired AI will not take over your job, or you may feel miserable how much effort is spent on this task and how badly everything fails in real-world scenarios
- finally, something we agreed with a professor advising a doctorate candidate whose thesis surprisingly was on the same topic. basically given GraphQL and other structured formats such as JSON, which LLMs are much better leaned on than the complex grammar of SQL which is not a regular grammar, but context-free one, which takes more complex machines to parse it and also very often recursion.
- which brings us to the most important question - why commercial GPTs fare so much better on it than local models. well, it is presumed top players, not only use MoEs but they also employ beam search, perhaps speculative inference and all sorts of optimizations on the hardware level. while this all is not beyond comprehension for a casual researcher at a casual university (like myself) you don't get to easily run this all locally. I have not written an inference engine myself, but I imagine MoE and beam search is super compled, as beam search basically means - you fork the whole LLM execution state and go back and forth. Not sure how this even works together with batching.
So basically - this is too expensive. Besides atm (to my knowledge) only vllm (the engine) has some sort of reasonably working local beam search. I would've loved to see llama.cpp's beam search get a rewrite, but it stalled. Trying to get beamsearch working with current python libs is nearly impossible for commodity hardware, even if you have 48gigs of ram, which already means a very powerful GPU.
