I've been surprised to find that sometime in past six months or year, ChatGPT has generally started returning better results than Google for me. OpenAI probably has fewer employees than Google Search alone, and what fraction of OAI works on search? On the order of 1%? Arguably an unfair comparison because ChatGPT takes 20x longer to return a result, but Google doesn't have a "20x slower but don't return https://danluu.com/seo-spam/ knob" OpenAI Google Related

A lot of hype around OpenAI's Astra model here on my timeline today. Apparently, this goes back to a new article from The Information, which said Astra is a "recurrent depth or looped transformer". It's always interesting to read about new or different approaches (including rumors about what the closed labs may be up to), but let's debunk this a bit. About 2 months ago, I shared the architecture details of Nanbeige, for example, where "Nanbeige4.2-3B is pretrained from scratch on 28T tokens with a Looped Transformer that reuses the layer stack to increase capacity without adding parameters."… OpenAI Related

This is pure gold data Companies focused and lost by the hype of AI without build their own SDLC powered by AI is the recipe to fail. Learn -> Measure -> Build 🔁 That's the cicle. No "please use AI for whatever you build". Then the billing hurts to pay and I'm not talking about tokens. Related

Someone just sent this to me. I remember first seeing it back then in…an official WWDC QuickTime movie from Apple, distributed on optical discs, maybe? Anyway, can you imagine today’s Apple even keeping a moment like this in an “official” video? (Apple did keep @marcoarment’s bell in that one WWDC video, but that was a minor miracle.) youtube.com

And that's why every hype cycle produces a wave of absolutely spectacular demos and very few real products. And the recurring mistake of every cycle is spending on the demo when you should be saving for the nines.

And the impact of solar array on desert is arguably positive because it shades the ground and improves like soil moisture retention. Um there like if you wanted to reverse desertification, you would basically just deploy solar panels on it and that would pay for the process.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.
