I'm not saying everyone has to run local LLMs, because the APIs are in a race to the bottom, and my $10 of OpenRouter credits I bought months ago is down to $8.94 because most models give you MILLIONS of tokens for a US Quarter.
This is tunnel vision. The percentage of people who could afford the hardware you could at the time you back it so vanishingly small. I do not know a single non-tech person who has multiple graphics cards in a single computer.
My personal expectation is closer to 5 years than 10, which is why I wouldn't touch Anthropic or OpenAI stock with a ten-foot pole, personally, no matter how high their theoretical valuation is. Because their business model is doomed in the long run.
Don't get me wrong, there are advantages to a fully local model in that, I can have agents looping 24/7 even when my internet is not working. But this is niche enough that if I had to price the advantages they don't seem worth it.
If I'm willing to pay the Openrouter tax, I can fire up Openrouter today and just get access to whatever model I want, and still pay a fraction for tokens as what I'm paying with the big guys.
3090 pricing is something of a wild card. Since the only big-mem consume cards are the xx90s, and a 5090 is pushing $5000, resale value has gone way up. The bottom hit ~$700 last year. It's still a very good GPU, if power hungry.
