About "people still thinking LLMs are quite useless", I still believe that the problem is that most people are exposed to ChatGPT 4o that at this point for my use case (programming / design partner) is basically a useless toy. And I guess that in tech many folks try LLMs for the same use cases. Try Claude Sonnet 3.5 (not Haiku!) and tell me if, while still flawed, is not helpful. But there is more: a key thing with L…

> Code hallucinations are also the least damaging type of hallucinations, because you get fact checking for free: if you run the code and get an error you know there's a problem. This is great when the error is a thrown exception, but less great when the error is a subtle logic bug that only strikes in some subset of cases. For trivial code that only you will ever run this is probably not a big deal—you'll just fix i…

Yeah, the other skill you need to develop to make the most of AI-assisted programming is really good manual QA.

QA are going to be told to use AI too

(Seems every job is fair game according to CTOs. Well, except theirs)

"The story of linear algebra begins with systems of equations, each line describing a constraint or boundary traced upon abstract space. These simplest mathematical models of limitation — each equation binding variables in measured proportion — conjoin to shape the realm of possible solutions. When several such constraints act in concert, their collaboration yields three possible fates: no solution survives their col…

Even putting it here is annoying to me... Those are a lot of words saying nothing that I just spend time reading.

I'm agreeing with you.

The key skill in getting the most out of LLMs is learning to work with tech that is both inherently unreliable and incredibly powerful at the same time.

When I started my career in 2010, google was a semi-serious skill. All of the little things that we know how to do now such as ignoring certain sites, lingering on others, and iteratively refining our search queries were not universally known at the time. Experienced engineers often relied on encyclopedic knowledge of their environment or by "reading the manual".

In my experience, LLM tools are the same, you ask for something basic initially and then iteratively refine the query either via dialog or a new prompt until you get what you are looking for or hit the end of the LLM's capability. Knowing when you've reached the latter is critically important.

Look, when are these models going to not just talk to me, but do stuff for me? If they're so clever, why can't I tell one to buy chocolates and send them to my wife? Meanwhile, they can allegedly solve frontier maths problems. What's the holdup to models that go online and perform simple tasks?

The last mile problem remains undefeated.

My fav part of the writeup at the end: """ LLMs need better criticism # A lot of people absolutely hate this stuff. In some of the spaces I hang out (Mastodon, Bluesky, Lobste.rs, even Hacker News on occasion) even suggesting that “LLMs are useful” can be enough to kick off a huge fight. I like people who are skeptical of this stuff. The hype has been deafening for more than two years now, and there are enormous quan…

There's a similar dynamic in building reliable distributed systems on top of an unreliable network. The parts are prone to failure but the system can keep on working.

The tricky problem with LLMs is identifying failures - if you're asking the question, it's implied that you don't have enough context to assess whether it's a hallucination or a good recommendation! One approach is to build ensembles of agents that can check each other's work, but that's a resource-intensive solution.

I have a 2023 mbp, and I get about 100-150 tok/sec locally with lmstudio.

Which models?

hugging-quants/llama-3.2-1b-instruct-q8_0-gguf - 100-150 tok/sec

second-state/llama-2-7b-chat-gguf net me around ~35 tok/sec

lmstudio-community/granite-3.1.-8b-instruct-GGUF - ~50 tok/sec

MBP M3 Max, 64g. - $3k
