This is not said often enough.
Yes, local LLMs are great! But reading most HN posts on the subject, you'd think they're within reach of Opus 4.7.
There is a very small, very vocal, very passionate crowd that dramatically overstates the capabilities of local LLMs on HN.
That all being said I've spent hundreds (maybe thousands?) of hours on this stuff over the past few years so I don't see a lot of the rough edges. I really believe capability is there, Gemma 4 31B is a useful agent for all sorts of stuff, and anything you can reasonably expect an LLM to oneshot Qwen 3.6 35b MoE will handle at like 90tok/sec, absolutely fantastic for tasks that don't require a huge amount of precision.
EDIT: Here's another sample for ya. I went to the store to buy mixers and while I was out Gemma 4 31b got pretty far along with reverse engineering the bluetooth protocol of a desk thermometer I have. I forgot to turn on the web search tool, so it just went at it, writing more and more specific diagnostic logging/probing tools over the course of like 8 turns. It connected to the thermometer, scanned the characteristics and had made a dump of the bluetooth notification data. When I got back it was theorizing about how the data might be encoded in the bluetooth characteristics and it got into an infinite loop. (local models aren't perfect and i never said they were) I turned on the websearch tool and told it to "pick up the project where it left off", it read the directory, did a couple googles and had a working script to print temperature, humidity and battery state in like 3 turns. Reading back throught it's chain of thought I'm pretty sure it would have been able to get it eventually without googling.
idk, I thought I was a cool and smart engineer type for being able to do stuff like this, if my GPUs being able to do this more or less unsupervised isn't impressive I guess fuck me lol.
I find them useful in basic research and learning and question asking tasks. Although at the same time, a Wikipedia page read or a few Google searches likely could accomplish the same and has been able to for decades.
I have seen way too many people who are overly optimistic about local LLMs.
Having spent a decent amount of time playing with them on consumer nvidia GPUs, I understand well that they not going to be widely usable any time soon. Unfortunately not many people share that.
Relatively speaking local models might always be behind the curve compared to frontier ones. You can tell by the hardware needed to run each. But in absolute terms they're already past the performance threshold everyone praised in the past.
Right now in a lab somewhere there's a model that's probably better than anything else. There's a ChatGPT 5.6, an Opus 4.8. Knowing that do you suddenly feel a wave of disappointment at the current frontier models?
When were you trying local models? The model releases from April 2026 are a serious change in performance.
These are so far from Opus it's not even funny. They are not close to being in the same league. Gemma might be like a frontier model from a couple years ago, but with much worse performance in long context chats.
To me, these small local LLMs are highly useful (and this “usable”) even though they don’t match the output of today’s frontier models.
No one is saying a local model will give you anthropics business in a 5min download. People are saying, "hmm, maybe I should do this one locally". People are also saying "this is surprisingly good enough for me given the trade offs"
If your time is worth nothing to even triage that question.
Unless you have fanatic needs for data privacy or really don't have Internet, running local models almost certainly results in negative ROI overall.
Not to mention that you need to have decent hardware (that is getting expensive by the day) to even have this conversation in the first place.
People in this post talk as if everyone has a Mac with 24GB or 32GB RAM. When the reality is that most people use a Windows laptop with crappy integrated GPU.
A local model is as good as a frontier model for responding on a signal threat with you which requieres basic tool calling.
A local model is as good as a frontier model of writing a joke.
A local model is as good as a frontier model at responding to an email.
Not sure what needs to be said often enough, no one without a clue would play around with local model setup and would compleltly ignore frontier models and their capabilities?!
You can have good local LLM performance through agents, but you need fast inference. Generally, 2x 3090 or at the minimum 2x3080s (you need 2 to speed up prefill processing to build KV Cache). You just ironically need to be good at prompt engineering, which has a lot of analogue in real world on being able to manage low skilled people in completing tasks.
Edit: TIL it is MoE and only has 3.6B active, explains a lot.
Same laptop, and my contrived test was having it fix 50 or so lint errors in a small vibe-coded C++ repo. I wanted it to be able to handle a bunch of small tasks without getting stuck too often.
GPT OSS 20B was usable but slow, and actually frequently made mistakes like adding or duplicating statements unnecessarily, listing things as fixed without editing the code, and so on.
Qwen 3.5 9B with Opencode was much faster and actually able to work through a majority of the lint warnings without getting stuck, even through compaction and it fixed every warning with a correct edit.
I tried 4bit MLX quants of Qwen 3.5 9B but it eventually would crash due to insufficient memory. I switched to GGUF, which I run with llama.cpp, and it runs without crashing.
It is absolutely not comparable to frontier models. It’s way slower and gets basic info wrong and really can’t handle non trivial tasks in one go. I asked it for an architecture summary of the project and it claimed use of a library that isn’t present anywhere in the repo. So YMMV, but it’s still nice to have and hopefully the local LLM story can get much better on modest hardware over time.
