Something surprising Sam Altman mentioned on the Lex Fridman podcast was that it only takes about 6 months to get a top physicist up to speed and productive researching AI. So the team could largely be newbies to AI (with extremely good fundamental knowledge/skill), rather than folks we've all heard of from the AI scene.

Does Sam Altman have any relevant technical experience to make that assessment? Sounds like something someone would say that just lost their key technical team members.

For whatever it's worth, Scott Aaronson went from incisive skeptic to drooling fanboy in just about that long. Sam, likewise, seems prone to mistaking loyalty for expertise at this point in his career.

This is a peculiar company mission so not sure why you find it odd to make the official one of xAI. The all-encompassing nature of it seems befitting a company producing increasingly general-purpose AI.

Sure it does. The problem is that they're not producing any general-purpose AI.

I wish he’d just focus on SpaceX or Tesla (the cars, not the robot).

Part of xAI is to be leverage against Tesla not giving him more control.

He’s been actively pushing for more control of Tesla for exactly this https://electrek.co/2024/05/20/elon-musk-confirms-threat-giv...

Unitree is better than Optimus. Qwen et al is better than Grok. BYD is better than Tesla.

> Comma.ai is better than Tesla FSD I don't know about the other comparisons mentioned, but Hotz himself said comma is/has always been about 2 years behind Tesla.

Did GP ninja edit their comment? I don’t see that quote

I still fondly remember the story an OpenAI rep told about fine-tuning with company slack history. Given a question like "Can you do this and that please." the system answered (after being fine-tuned with said history) "Sure, I'll do it tomorrow." Teaches you to carefully select your training data.

The datasets should not be used for knowledge but to train a language model.

Using it for knowledge is bonkers.

Why not buy some educational textbook company and use 99.9% correct data? Oh and use RAG while you are at it so you can point to the origin of the information.

The real evolution still has to come though, we need to build a reasoning engine (Q*?) which will just use RAG for knowledge and language models to convert its thought into human language

How does one differentiate knowledge from the language model in an LLM? At least in a way that would provide a benefit?
