Yeah definitely. I've recently commented on that: https://news.ycombinator.com/item?id=48557890

In the context of local LLMs on limited hardware I've ran to the exact same conclusion: "tok/s" isn't the most useful metric when my personal North star metric, given my fixed hardware is: Model smart enough to execute my goals _in the minimum amount of time_.

Some models I tried (Mistral I think) had better tok/s, and roughly same billion parameters / scores on various benchmark... But they were _so_ verbose, that they generated many more tokens compared to a Qwen model of same caliber to answer the same thing.

So even though it had better generated tok/s, because so many more were generated, the clock time was longer.

And this compounds over mutli-turns: more generated token means more context used in the next turn (until some compaction or something runs)

Pretty sure this flag hasn't done anything for a while. It's enabled by default since ~November of last year

The huge spike of "lk-99" in science & frontier tech is amusing...

This is cool concept, would love a positive/negative sentiment computed for each comment that refers to a given word, so you can see trends of "cloudflare (positive)" vs "cloudflare (negative)" where first one counts comments only if sentiment confidence is greater than say 0.6 and the other one counts comments only if sentiment is less than 0.4 (assuming [0,1] sentiment score)

Thanks! Super helpful.

I do use it the same way as you're describing on personal projects at home, in a very crude manner (pasting code snippets in llama server web UI prompt. Next will attempt OpenCode)

At work I use it in similar manner with more mature tools, but the vast majority of token spend comes from a totally different workflow: "pretend the AI is a fleet of junior/intern engineer you're delegating work to", where the agent will on its own do the implementation, commit the changes etc.

It does indeed spend a lot of tokens wandering the codebase, talking to MCPs, loading skills etc.

> About the generation speed: ~100-150 t/s on the RTX 5090 and ~40 t/s on the Mac

Curious if you can share the prefill speed too?

I run locally on a crappy desktop (some AMD iGPU with Vulkan llama.cpp, 32 GB DDR4 RAM) for experimentation. I get 15 tok/s on generation for the qwen & gemma4 MoE models. I get around 150 tok/s prefill speed.

Reason I'm asking about the prefill is looking at my stats at work, I use between 20M to peaks of 300M input tokens daily. Some of those token are cached but in general, I seem to have roughly 500x more input tokens than output. So interested in prefill tok/s stats.

Huge Thank you for llama.cpp btw!!

Since you're running quantized (at UD-Q4_K_XL) , check out the "qat" models (unsloth/gemma-4-26B-A4B-it-qat-GGUF) !

I did the opposite switch:

In ~2015 got an Xbox one, as a media center it was an awesome experience:

Kinect voice control to play/pause and other things way before Google home/Amazon echo ecosystem were mature.

Free OTA channels via TV tuner and well designed OneGuide (with ability to pause and rewind).

And of course all the Netflix and other apps, Plex server etc.

But strategically it seems Microsoft decided they wanted to look more like Playstation, focused on gaming (at that time paid Xbox live subscription vs free Playstation)

And as gaws points out, they seem to recently announce to double down on the gaming stuff.

So when they discontinued OneGuide. I picked Roku since they seem to be focused on the media experience primarily... but unsure how I feel about this acquisition news.

> What's hard to figure out here?

Negative externalities are hard to figure out.

Since parent mentions "toxic byproduct": Say you're the company that invented Teflon pans. you made billions. You saved billions in time for all the users of the pans... A true entrepreneurial success.

But, by how many billions did you fuck up the environment, people's health etc with the spread of PFAS everywhere?

That seems a very risky assumption for any car (self driving or human driver) during flash floods. "Turn around don't drown":

You think you know how deep it is under because you've taken that road many times before (or in your case you have historical laser measurement)

But you don't know:

- Maybe the road under fully collapsed

- Maybe the flow of water is extremely strong, so you need to accurately estimate that too.

Speculative execution techniques in software & hardware exist everywhere,

- Speculative multi threading

- Data Value Speculation

- Speculative Memory Disambiguation

- Runahead Execution

- Speculative Prefetching

- Multi-path (Dual-path) Execution (goes beyond branch prediction by computing both paths)

- Optimistic Concurrency Control (for database transactions etc)

My non-controversial theory: It's all the attention-span-shortening stuff.

- tech apps starting with infinite scroll (facebook, 9gag, Instagram, etc.)

- media/tech shortened content: shorter tv shows, short video content, etc.

(Tiktok is the "state of the art" of those 2 trends pushed to the max)

Specifically, we're getting more & more addicted to things that increase the dopamine spikes frequency, making it increasingly difficult to go in deep focus work.

But isn't the prefill speed the bottleneck in some systems* ?

Sure it's order of magnitude faster (10x on Apple Metal?) but there's also order of magnitude more tokens to process, especially for tasks involving summarization of some sort.

But point taken that the parent numbers are probably decode

* Specifically, Mac metal, which is what parent numbers are about

When you say tok/s here are you describing the prefill (prompt eval) token/s or the output generation tok/s?

(Btw I believe the "--jinja" flag is by default true since sometime late 2025, so not needed anymore)

Some might be tempted to brush aside that Server Linux threat model is very different from Desktop Linux (to snarkily reply "we'll it's powering a vast majority of GDP via all of AWS, Azure, etc.").

However comparing apples to apples, what makes you say this isn't ready for government usage, when it's ready for trillion dollar big tech companies' majority of their workforce? (Aside from Microsoft, Apple obviously). Large employers like IBM etc also must be using red hat or some other distro

> I'll need to investigate further but it doesn't seem promising.

That's what I meant by "waiting a few days for updates" in my other comment. Qwen 3.5 release, I remember a lot of complaints about: "tool calling isn't working properly" etc.

That was fixed shortly after: there was some template parsing work in llama.cpp. and unsloth pulled out some models and brought back better one for improving something else I can't quite remember, better done Quantization or something...

coder543 pointed out the same is happening regarding tool calling with gemma4: https://news.ycombinator.com/item?id=47619261

Wild differences in ELO compared to tfa's graph: https://storage.googleapis.com/gdm-deepmind-com-prod-public/...

(Comparing Q3.5-27B to G4 26B A4B and G4 31B specifically)

I'd assume Q3.5-35B-A3B would performe worse than the Q3.5 deep 27B model, but the cards you pasted above, somehow show that for ELO and TAU2 it's the other way around...

Very impressed by unsloth's team releasing the GGUF so quickly, if that's like the qwen 3.5, I'll wait a few more days in case they make a major update.

Overall great news if it's at parity or slightly better than Qwen 3.5 open weights, hope to see both of these evolve in the sub-32GB-RAM space. Disappointed in Mistral/Ministral being so far behind these US & Chinese models
