If you play with these models long enough, you realize there is more to them than just "model X is smarter than model Y" or "model Y is cheaper than model Z". They are different tools and the prompting technique is different. It is very much like playing an instrument.

With Claude, you sometimes want to under-specify or phrase things more indirectly to give a color to the implementation or elicit something creative. Also (you might raise an eyebrow at this) being nice to Claude will be rewarded and being mean to Claude will be punished. Claude tends to mirror your tone more aggressively and you don't want to get into negative loops with it.

With GPT, you have to be precise and reduce ambiguity. GPT will often try to resolve ambiguity in a min-max style "I'm going to do X, but make sure it is not quite Y". It will tend to be more paranoid and overengineer to catch all edge cases if you don't tell it precisely what the scope is.

With Qwen, you have to give it a shape and let it fill it in. Qwen likes XML, JSON and lists. Qwen likes to be shown a bunch of examples of previous work.

This is not scientific at all, just vibes, YMMV.

while not scientific this is been my experience as well. i will add that language specificity in word choice is also a learned behavior. for example, the word “investigate” vs the phrase “look into”. You will find the outputs are quite different. can you guess which will use more tokens? it’s stuff like this that actually sets people apart in the top percentile of using these tools

Mmm..interesting..So now people are finding behavior patterns in LLMs which are trained on behavior patterns of people...

> It is very much like playing an instrument.

Or it is more like playing a slot machine and you imagine the rest.

stingraycharles•about 2 hours ago
I agree with your general gist, and in general it’s a “the best tool for the particular job”, keeping token spent and other things in mind as well.

What I do know absolutely for sure is that LLM benchmarks are not to be trusted, they are just a minor indicator and real world usage is often very different.

willtemperley•28 minutes ago
Yes, how do we know Opus 4.8 hasn't been trained on the SWE-Bench examples?

With a squillion dollars at stake per bench point, someone will have figured out a plausibly deniable way to game these benchmarks.

sanderjd•about 2 hours ago
I share this sense, but my immediate thought is that we need to improve the evaluations! Do you think this is impossible? That there is something indelible that it is not possible to capture empirically? I kind of have this intuitive sense that it is this way, but simultaneously I think that it's unlikely to really be true.
theshrike79•19 minutes ago
We shouldn't just measure the power of the raw LLM, harnesses matter more and more.

It's like taking the engine out a each car, putting it to a test bed and running it and then making a decision whether the car is good or bad based on the graphs the test bed provided.

You might have the best engine in the world, but if you put it in a shit car, the result is still bad. The seats are squeaky plastic, the infotainment is touch-only and you can't put on your seatbelt without knocking down whatever is in the cupholder.

gbalduzzi•31 minutes ago
Following the original comment concepts, if every model requires a different prompting technique to maximize its output, how can a benchmark based on sending the same prompt to all models be accurate? We should create different prompts for each model, but then how reliable and unbiased can the benchmark be?

It is a fundamentally hard problem to solve

dv35z•about 1 hour ago
What would it take to have trustworthy benchmarks? As with all "targets", they can be gamed - but I am curious about quantifiable quality metrics.
sixtyj•29 minutes ago
Issue with LLM benchmarks is similar to cars’ benchmarks. Eg journalists almost always get the full equipped model so their review is honest but sort of rigged.

I haven’t seen details of LLM benchmarks’ data sets but I would suppose that “questions” are public so known in advance therefore you can tune a model as much as possible.

One of real benchmarks is drawing of pelican - https://github.com/simonw/pelican-bicycle - Simon Willison made it for his llms’ tests.

If you want really find out a model that works for your specific purpose I would recommend several rounds at arena.ai - it helps to find a anonymously a model without confirmation bias.

Some ppl: Claude is the best! Others to them: but Qwen is the best! Or… Codex is better! …

it all depends on the language (English, Dutch, French…), style of querying (caveman, specs, skills, goal etc.)

Even with the same model I get different answers to same prompt that is just tweaked a little.

So benchmarks are nice but mostly useless.

Without your usecase it is just a reference number indicating the approximate position of that model among the others. And for those who want to make money it is a marketing tool to sell more as every customer counts.

da-x•18 minutes ago
Maybe someone can devise a distributed bench-marking system where multiple people collaborate on tests and also vet each other's tests and rating without revealing them to the public.

I have my own "interview questions" for models where I give them a premade Git repo and a problem to solve. Then, I rate them like a teacher. I believe other do that as well, so we only need a reliable system to aggregate these results.

theshrike79•22 minutes ago
You can't measure "feels".

One good analogy is the Macbook vs generic windows laptop debate online.

The engineer mind just compares numbers, the Lingwoo laptop from Amazon has biggest numbers for everything and the lowest price. Ergo it is the best.

But the numbers don't measure the fact that the Lingwoo creaks and squeaks when you lift it due to the cheap plastic. It also runs at 100C when both CPU and GPU are fully utilised. The keyboard feels like a membrane keyboard from a milspec device from the 90s. Numbers also don't measure the fact that Linwoo is an alphabet soup whitelabel manufacturer that won't exist in any legal capacity in 6 months so good luck with any warranty issues.

There will be an identical laptop called Chongwin being sold though. Completely different company, definitely.

--

The same applies to LLMs. You can do benchmarks like ask them to one-shot different kinds of gotcha questions (car wash, strawberry and other idiotic ones) or get them to write different kinds of programs.

But that doesn't measure the UX of doing so at all. How many times do you actually need any of those when you're actually working?

It's like unit testing an application. Every function can have 100% test coverage and the app can still be shit because there are things you can't unit test for.

vkazanov•about 2 hours ago
The problem is not that there details, the problem is constantly shifting ground. We can only rlpy on a harness to be sort of predictable but the models change all the time.
rkuska•33 minutes ago
It system prompts that change all the time especially in claude code.
hashmap•about 1 hour ago
totally true. one key for claude is to not smell like an evaluator, its good at knowing when its being tested and will behave defensively and avoid doing work. i avoid this basin by typing unreasonably excited about the thing i want done. like way over the top. it's harder to keep that up than it sounds.
glerk•25 minutes ago
at the risk of sharing my secret magic spells :)

> this is phenomenal work, genuinely! I feel like you read my mind! <next instruction here>

can go a long way.

of course, I would only say that when I mean it, because Claude can get superficial and cut corners which is why I prefer GPT for raw implementation.

theshrike79•29 minutes ago
Yyep.

IME Claude is the most "creative" of the bunch, you can get surprising ideas out of it that were kinda tickling the back of your head but didn't really connect.

BUT it's also "relentlessly proactive" like simonw put it. It _will_ get the job done, it's the smartest idiot in town. Why use a library to parse $format when you can just write a custom 1000 line parser? Or if it can't access something, it'll pursue the goal of accessing it in the most creative ways - instead of stopping, asking the user "yo, can you give me access to X" and then continuing.

My solution is to use Claude as a pair programmer. I _very_ rarely just do /goal fix this shit, I watch what it does and interrupt if it gets to the "smart idiot" phase. Also I communicate with it like I would a coworker, never had it berate me or get combative. There's a Finnish proverb for that too[0]

As for Codex, Deepseek, GLM, those I use when the goal is 100% clear like "convert this Brewfile to a list of packages for Arch and Debian, use these two Docker containers to test that pacman and apt work correctly". Boom, done.

But I won't give any creative open-ended tasks to any other model than Claude.

These are the vibes that power vibecoding.
zmmmmm•about 2 hours ago
That's a great write up.

The one thing I feel it seems to under estimate is the likelihood of improvement. Even the authors acknowledge it's not even worth comparing local models from a year ago to what we have now. In fact, people widely see Opus 4.5 in November last year - 8 months ago - as the first time agentic coding became viable broadly viable even with frontier hosted models.

So why would we lock in hard on any concept at this point of what a local model is and isn't good for? Whatever it is right now, it probably won't be that in a year. It might be naive optimism to think we'll ever get to long horizon tasks with models that run on consumer / pro grade hardware. But so far the naive optimists are winning.

sanderjd•about 2 hours ago
Right. Opus 4.5 8 months ago, good enough for agentic coding. How far behind that are open weight models? More than 8 months? But how much more? When will they reach Opus 4.5 level? A few months from now? A year from now? Never?
theshrike79•18 minutes ago
The power of Opus isn't just the model, it's in the harness too.

You can try it by using Opus through Github Copilot vs official Anthropic tools. You'll get very different results and experience (in my opinion).

theplumber•about 1 hour ago
I think in the next 6 months we will have Opus 4.5 performance in open models. We are very close
marak830•about 1 hour ago
GLM 5.2 came out today and the early reports have been quite good. Very difficult to run except on prosumer hardware, but small business could quite easily (or something like open router).
rippeltippel•about 2 hours ago
Since the author is referring to a specific model, I think it makes sense to ignore how the model (or local models in general) may improve over time.

It's like buying a car: I drive that car and get attuned to its characteristics; I don't think how that car (or similar cars) may improve. That's my tool and I want to make the most of it.

It is true that switching a local models it technically very cheap, but there's a considerable time investment in squeezing the most out of it, which may not work on a newer version of that model.

appplication•about 2 hours ago
Agree 100%, even on claude 4.5 being the turning point for agentic coding. It completely turned me around on it.
hypfer•about 2 hours ago
That was a lot of text for me still having no idea what the point of the author was (beside what I can infer from the headline that is).

I do however now know that they're a totally cool dude building stuff physically and as software + that other people give them money for it.

Does that have anything to do with the topic suggested by the headline? Not sure.

neonstatic•about 1 hour ago
Everything is an ad these days. The article was not useless, but for the information it provides, it could have been two paragraphs.
hypfer•about 1 hour ago
FWIW it told me stuff about openfaas. Now I know how to mentally file it and how to mentally file the author. The GitHub profile alone might not have sent the same signal, so this is useful.

Is it bad software? Idk. Probably not.

Should you treat it as a grassroots Foss thing maintained by fellow sane hackers? No sir.

gpt5•about 2 hours ago
This article is a good summary of local models. Unlike the way they are hyped sometimes, as fantastic tools for coding and agentic local work. The reality is that they are rather limited, would not do well on a long or complex task, and are prone to fall into loops, forget their tasks, etc. Not mentioned in the article is that they are also rather expensive - not just for the hardware cost, but also electricity. These 3090 and 5090 machines are pretty power hungry, and these models are pretty slow on these machines, making them consume more power per token.t

Where they shine is in your ability to control them, their privacy, their predictability (e.g. if you are doing a repetitive task, like classifying your photo/video library), and depending on your energy bill - their costs.

theshrike79•14 minutes ago
My dream would be a local model that can do, say, 80% of the day to day tasks I need; "how does X Handler connect to Y storage?", "commit that feature, but leave out the bits that relate to billing" etc.

It would have 99% reliable tool calling - and most importantly - the ability to go "this task is beyond my skills" and refer to a Big Boy Online Model in a gigantic datacenter somewhere.

This way all of the simple stuff would be done on-device, gathering data, figuring out the context of the problem etc. And when that's done, the "smart" model would come in to work on the issue when all of the easy stuff is already done.

It feels super stupid that my /commit skill calls an online model when that is something a local model can 100% do. Mostly this is a harness issue though and mostly solvable.

usernomdeguerre•about 2 hours ago
I believe that local models are a necessary extension of the personal computer and I imagine that one could have had similar criticisms of early personal computers.
pmontra•about 1 hour ago
Of course the early MSDOS PCs where loud and power hungry. I can't remember the specs but according to Wikipedia the IBM PC with a 80286 had a 192 Watt power supply. I don't remember if by then we had internal hard disks or we still had to buy a case as large as the one of the PC with a 10 or 20 MB disk inside. It was handy to raise the monitor further up.

> Unlike the way they are hyped sometimes, as fantastic tools for coding and agentic local work.

They really are fantastic for a lot of use cases and I think most people do not need SOTA. When I run that qwen model in my measly 4070 12 GB for my personal email agent that I build and experiment with, I need privacy more than anything else. It does a great job. Even for coding tasks, given you know how to use them instead of dumping a grand plan, it's great.

sanderjd•about 2 hours ago
But that's current hardware. What about future hardware? What about hardware optimized for inference? What about hardware optimized to run a particular model?
cptskippy•about 2 hours ago
I've been running qwen3-5-9b-q4-k-m and qwen3-6-27b-q6-k simultaneously on an Intel Arc Pro B70 with a lot of success.

https://github.com/cptskippy/battlemage-llm-gateway

Opencode has been a huge productivity accelerator. I have two Hermes agents that I'm training to support my workflow with pretty good success. One is a personal assistant who manages my backlog and keeps me on task, follows up with me on items, and will put together research briefs. The other I use a general purpose coder and research and it's about 50:50 with the tasks I've given it. In fairness though, the task it failed at left me scratching my head to figure out as well.

Does Intel make decent GPUs now? I must be out of the loop...
speedgoose•39 minutes ago
They released a few good value GPUs for LLM inference about a year ago: more memory than AMD and NVIDIA consumer GPUs, not too expensive, but also not great tokens/watt.

I am not sure whether you can find those in stock anywhere.

hbbio•about 2 hours ago
Interesting setup, thx for sharing.

How many tokens/sec do you get with 27b? Are you using MTP?

jauntywundrkind•about 2 hours ago
What's the value running the smaller model too? Why not just the big model for everything? I note both are dense, as well.
Ritewut•about 1 hour ago
Tokens per second. The difference between 8B and something like 16B is not as big as you might think in practical usage and 8B is a lot faster and interactive than 16B but there are certain things where it is useful to farm it out to the large model.
Natalia724•about 1 hour ago
Agree. For local coding help, latency often matters more than raw benchmark quality. A slightly weaker model that answers immediately changes how often you reach for it.
