#32I doubt it will ever be cost effective for the foreseeable future. The AI companies have astonishing amounts of compute and they’re effectively dumping it on the market.

You can't run recent openAI/Anthropic models locally anyway, so wouldn't a better comparison be a different provider running Qwen or similar model? As then you can also compare against the exact model you'd have locally and any different data privacy of that particular provider ?
In May of this year, I was running qwen3.6:35b-a3b on my MacBook (bought in 2024). Obviously not as fast as, say, running a model on Cerebras, but a year ago it wasn't really feasible to have a local model running on my 2024 laptop with vision support. (Concretely, I was passing apartment diagram pictures to Qwen and making it compare different apartments for which ones would feel the most spacious while optimizing for initial moving costs and other factors.)
This was back in May and I wouldn't be surprised if there have been significant improvements since then.
Overall, I think it's fair to compare a workflow like "use llama.cpp locally to upload some pictures and ask questions" to "open the ChatGPT app, upload pictures from your phone, and ask questions". Sure, you can't run a model like GPT-5.4 locally, but the model is mostly an implementation detail here. What a user will care about is: "when I go with the llama.cpp option, am I getting useful information from my conversations?"

I'm curious what people are sending to Claude that is so secret. Claude knows about my interior decorating, questions about light bulbs, curiosity about what the Galactic Empire was even trying to do, unpacking SCOTUS decisions, shoe trees, Fed inflation history, etc. What part of my brain is contained here? Sure, the conversations have back and forth (some have dozens of exchanges), but, like, that's not the secret…
The proof to the Navier-Stokes problem.

Its the same point used against privacy. What's so secret you are doing that you need privacy. I think in the end, its about privacy and not trusting these model companies with your data. Facebook manipulated people behaviors with all the data they had, no reason AI companies wont someday decide to do that same, and they have far more intimate knowledge.
When it comes to coding, I also don't like the idea of them taking my money and potentially at same time potentially using as dataset generator.

#39I wish you could put different setups on here. I have a couple of A6000s on an AM5.

#40Not a fair comparison really. If you can run a model locally then you can somewhat train out the guardrails, censorship, and brand-safety. That has value a subscription does not. Idk about the quality of this setup but just pasting it here as an example. https://explainx.ai/blog/heretic-llm-abliteration-guide-2026
> If you can run a model locally then you can somewhat train out the guardrails, censorship, and brand-safety. When does the average person actually need to do that?
I expect this is only going to get worse. "Censorship" isn't just going to be about who you vote for and which political party the model will say nice things about and which it is more likely to say bad things about. It's going to become about whether the hoi polloi are allowed to have effective AIs at all. Like the 1990s internet, AI has outrun a lot of power structures but that is not going to continue indefinitely.
