My comparison of its reasoning efforts[0] seems to show that it only really supports 3 modes: none, low, xhigh. Low and medium are basically the same. Also, the electricity it costs to run on a 3090 is not negligible, so that it's cheaper to use Luna high via API than Qwen 3.8 27b locally, hardware costs excluding.

$0.286/kWh is a ridiculous amount of money to pay for power. That's more than double the regional residental average here! If I ever found myself in this situation I would much rather just rent cards from hotasile and run open models instead of giving OAI money and playing reset bingo
Qwen 3.8 27B is excellent, but it defaults to overthinking things

#282It won't satisfy the people who just want to drop a model into their existing toolset and run, but I think there are a lot of ways to deal with this overthinking problem. For instance, it's a step backward, but I put {"reasoning_effort":"none"} and led it by the nose: User: We're going to make . Please create a plan, but do not write code yet. Agent: User: Now please follow that plan and write the code. No other chat…
My impression is that when you allow the model to use internal thinking as opposed to asking it to output its thinking first, it's more likely to backtrack when I detects a flaw in its plan. Said otherwise: once producing user-facing output it seems to lock into an approach, for better or worse.

And what's the right way to use Gemma? Where can I find the correct template and settings if those aren't the ones provided by Google, Unsloth, and aren't built into llama.cpp? I discarded using Gemma 4 because it got into weird loops when tool calling
Some weeks ago a new official Gemma 4 release was posted that corrected some of the chat template problems. So the official release files on hugging face should be the way to go.

Indeed. LLMs resemble human intelligence in more or less the same way that the output of the TI-99/4A speech synthesizer resembles a human voice.
Not if an LLM over chat can fool most people they're talking to a human (which it can), where the TI-99 speech synthesizer voice absolutely can not.
To me it just means they can brilliantly fake human conversation - the original design goal of Large Language Models.
It's really easy to tell if you're talking to an LLM if you ask a question that requires actually knowing things, not going for the first search result of a tool call or whatever most popular answer was embedded in the weights.
For this reason even the most sophisticated models still require system prompts, skills and all that other crap.

> Not if an LLM over chat can fool most people they're talking to a human (which it can) I keep hearing this claim, and yet I keep seeing LLM output which is trivially distinguished from human writing. I really can't understand how this gap persists; but then, there seem to have been at least some people who couldn't sniff out ELIZA, back in the day, too.

#286“The fact that a 17GB file can do all of this stuff on my home machines is a miracle. Once again, I’m delighted and amazed at how much progress local models have made this year.” I think that should be the blinking headline - this shows what can be done with consumer hardware.
I thought the same thing, and I generally do a lot of animation in my work, and the results in motion graphics with Qwen are impressive, I really fell in love with it

Solar power and batteries are getting cheaper and cheaper at the moment. So Watts should become cheaper in the long run. Especially when chips are becoming cheaper (in the capex sense), then you can afford to only run them when power is cheap. Btw, from where do you take the notion that performance per Watt ain't increasing? We are also still using what's more or less general purpose GPU hardware; we could get a lot…
Like I said, just feels I have from the consumer-hardware space. For several generations of GPU now most improvements come from packing more transistors into a larger die than packing more transistors closer to each other. GPUs have been getting physically bigger with huge heatsinks and fans to support those bigger dies power consumption. Just compare the TDPs: 2020 RTX 3090: 350W 2022 RTX 4090: 450W 2025 RTX 5090: 5…
