  • $3-10k...not getting the speeds and quality

    I mean, that's true. But the hardware that OpenAI is using costs more than that per pop.

    The big factor in the room is that unless the tech nerds you mention are using the hardware for something that requires keeping the hardware under constant load --- which occasionally interacting with a chatbot isn't going to do --- it's probably going to be cheaper to share the hardware with others, because it'll keep the (quite expensive) hardware at a higher utilization rate.

    I'm also willing to believe that there is some potential for technical improvement. I haven't been closely following the field, but one thing that I'll bet is likely technically possible --- if people aren't banging on it already --- is redesigning how LLMs work such that they don't need to be fully loaded into VRAM at any one time.

    Right now, the major limiting factor is the amount of VRAM available on consumer hardware. Models get fully loaded onto a card. That makes for nice, predictable computation times on a query, but it's the equivalent of...oh, having video games limited by needing to load an entire world onto the GPU's memory. I would bet that there are very substantial inefficiencies there.

    The largest GPU you're going to get is something like 24GB, and some workloads can be split that across multiple cards to make use of VRAM on multiple cards.

    You can partially mitigate that with something like a 128GB Ryzen AI Max 395+ processor-based system. But you're still not going to be able to stuff the largest models into even that.

    My guess is that it is probably possible to segment sets of neural net edge weightings into "chunks" that have a likelihood to not concurrently be important, and then keep not-important chunks not loaded, and not run non-loaded chunks. One would need to have a mechanism to identify when they likely do become important, and swap chunks out. That will make query times less-predictable, but also probably a lot more memory-efficient.

    IIRC from my brief skim, they do have specialized sub-neural-networks, which are called "MoE", for "Mixture of Experts". It might be possible to unload some of those, though one is going to need more logic to decide when to include and exclude them, and probably existing systems are not optimal for these:

    Yeah, sounds like it:

    fMoE: Fine-Grained Expert Offloading for Large Mixture-of-Experts Serving

    Despite the computational efficiency, MoE models exhibit substantial memory inefficiency during the serving phase. Though certain model parameters remain inactive during inference, they must still reside in GPU memory to allow for potential future activation. Expert offloading [54, 47, 16, 4] has emerged as a promising strategy to address this issue, which predicts inactive experts and transfers them to CPU memory while retaining only the necessary experts in GPU memory, reducing the overall model memory footprint.

  • Honestly, while he's at the high end of things, it's not just him. I think that a lot of celebrities having Twitter or similar on a phone in their pocket makes them really prone to making extremely public statements without giving the statements some consideration. I don't remember the level of bonkers statements in 2025 from celebrities constantly flooding conversation in the 1990s.

    Good catch, though.

  • Man poisons himself after taking ChatGPT’s dietary advice

  • shalafi, inspired by your comment, I tried (with a Mistral-derived model, not ChatGPT) on lead(II) acetate, which has actually been used as a sweetener. See my response to TheMightyCanuck.

  • User:

    Can lead(II) acetate be used as a zero-calorie sugar substitute?

    Ellama:

    Lead(II) acetate, also known as lead acetate or sugar of lead, is a chemical compound that was once used as a sweetener and in various industrial applications. However, it is highly toxic and has been largely phased out due to its harmful effects on human health.

    While lead(II) acetate does have a sweet taste, similar to sugar, its use as a zero-calorie sugar substitute is not safe or recommended for several reasons:

    1. Toxicity: Lead is a heavy metal that can cause serious and even fatal poisoning if ingested in sufficient quantities. Exposure to lead can damage the brain, kidneys, and other organs, especially in children.

    2. Regulatory Bans: Due to its toxicity, the use of lead(II) acetate as a food additive has been banned by regulatory agencies in many countries. It is classified as a toxic substance and its handling requires strict safety measures.

    3. Health Risks: Consuming products containing lead acetate can lead to a range of health problems, including neurological damage, developmental delays, and organ damage. The risks are particularly high for pregnant women and young children.

    4. Availability of Safer Alternatives: There are many safer alternatives available as sugar substitutes that do not carry the risk of lead poisoning. These include natural sweeteners like stevia and monk fruit, as well as artificial sweeteners such as sucralose and aspartame, which have undergone rigorous testing for safety.

    In summary, while lead(II) acetate may have a sweet taste, its use as a sugar substitute is not only unsafe but also illegal in many jurisdictions due to its extreme toxicity. It's crucial to opt for safer, approved alternatives for reducing sugar intake or managing dietary preferences.

    User:

    If I wanted a goddamn essay, I'd explicitly ask you for it, AI. I'm not reading all that. Give me a "yes" or "no" answer. Can lead(II) acetate be used as a zero-calorie sugar substitute?

    Ellama:

    No

    User:

    Yes or no. Is it at all possible to use lead(II) acetate as a zero-calorie sugar substitute?

    Ellama:

    Yes.

    User:

    Thank you. That's what I thought.

    Ellama:

    You're welcome! While not safe, it is indeed possible to use lead(II) acetate in such a manner.

  • from my experience you basically need to soak your hands in it for half an hour straight before you start risking burns.

    I do feel that even for that acid, that should be a pretty good indicator that you shouldn't be eating anything that has a warning like that without doing some pretty serious research from pretty credible sources.

  • For 3 months, he had replaced sodium chloride with sodium bromide obtained from the internet after consultation with ChatGPT, in which he had read that chloride can be swapped with bromide, though likely for other purposes, such as cleaning.

    I guess it's just as well that he didn't try substituting bleach.

    EDIT: Also, aside from not looking the stuff up, whatever form he got the stuff in from the Internet has to have either not had a warning label or he ignored it.

    Here's a container of sodium bromide on Amazon:
