  • It’s a bit misleading.

    Qwen 27B has way less “world knowledge” than GPT-5. Ask it random trivia without internet search access, and GPT would know waaay more.

    This is generally true of small vs large models.

    …But honestly, Qwen 27B is better at tool use or agentic stuff. It’s hyper optimized for just that and coding assistance, basically.

    This is often true of old vs new. Most newer models have hyper focused on agents/coding, often to the detriment of other use cases.


    Quantization for practically running Qwen 27V also has an impact. A off-the-shelf Q4_K_M is not the same as the unquantized weights in real-world use, or even an “optimized” quantization like a custom exl3.


  • Also, AI or not is really irrelevant for this case.

    They said as much:

    Saflor uses AI tools and does not believe that AI itself is the problem. Goldman pointed out that his arguments against Memes Apps would be largely the same even without the AI aspect. But Saflor considers Memes Apps’ platforms to be examples of irresponsible AI products, where the operators problematically advertise that you can “fire your ad agency” and replace all creative work with a meme generator.


    Which sounds to me like effectively abolishing the copyright system for anyone who can’t afford paying lawyers to hunt down every little infringement, only leaving it up for wealthy corporations.

    And yeah, that would be a really terrible precedent…












  • I just meant that you have to be cognizant of what went into the quantization.

    As an example, a “Q4_K_M” could be too much quantization to be usable on one model, and an inefficient waste of space on the other. Two Q4_K_Ms of the exact same model could be completely different, one totally borked. Or one particular Q4_K_M could excel in one task, but be totally useless for another, even with the exact same settings, when a slightly different sized or type of quantization would excel.

    It’s a deep rabbit hole. It’s not random either; there are distinct technical reasons behind every case mentioned above.

    And that’s not even at the cutting edge quantization anymore, though what’s “cutting edge” completely depends on your particular hardware and use case.


    I’m trying to make this sound daunting on purpose.

    Many people have really horrible experience with a default “ollama run” for this exact reason, because the defaults are terrible and the customization is critical to getting coherent, performant output.


    Unquantized LLMs, on the other hand, are basically always run the same way: vllm docker image on a big server, official weights. There’s less to “go wrong” trying to squeeze it on hardware with unofficial runtimes and compressors.
