@Yuchenj_UW Having some experience with software engineering probably helps.

Zuck’s AI safety take is basically the opposite of most frontier labs:
Most labs:
The more powerful the model, the more dangerous it is, so access should be restricted.
Zuck:
The more powerful the model, the more dangerous it is to let a few labs control it.
Zuck is Based. htt

OpenAI’s “significantly more capable than GPT-6 Astra” model solving a Millennium Prize Problem is huge, an AlphaGo moment for math.
AI is now smarter than a math PhD, but dumber than an intern in many tasks.
“Jagged intelligence” needs to be solved.

OpenAI’s comeback is the biggest comeback after Meta’s comeback, after xAI’s comeback, after Google’s comeback.
AI is an endless cycle of “it’s over” and “we’re so back.”

Sam and Jensen say “AGI has arrived.”
But “AGI” means different things depending on who you ask.
- Sam’s bar: outperform humans at most economically valuable work.
- Dario and Demis’s bar: smarter than a Nobel Prize winner across most fields.
These are wildly different bars.

If you want to understand how fast AI is improving, look at intelligence per dollar.
1.5 years ago:
o1 Pro: $150 / $600 per M tokens
Today:
GLM-5.3 Flash: $0.15 / $0.50
That’s a ~1000x collapse in price in under 1.5 years, while GLM-5.3 Flash is more intelligent than o1 Pro.

Whoever invented “Member of Technical Staff” was a genius.
It filters out Staff/Principal title-maxxers, protects engineering and research from corporate ladder brain, and leaves recruiters staring at LinkedIn like: “Is this person L4 or L7?”
MTS is the best title. Happy to be

@Yuchenj_UW It’s interesting that you can 3X the LR. You’d expect the original paper to be well tuned near what is tolerable.

@karpathy I'm unsure why the evaluation score dropped near the end. It might be due to some bad training data batch.
@karpathy, would love to hear your insights. It reminds me of the lossfunctions Tumblr though lol: https://t.co/9MQivsrCPI.

Outperform GPT-3 with @karpathy's llm.c using just 1/3 training tokens ✨
Another day has passed, and I trained GPT-2 (124M) with llm.c for 150B tokens, achieving 35.5% accuracy on HellaSwag. This surpasses the GPT-3 paper’s 33.7% accuracy trained for 300B tokens. It matched the

When starting OpenAI, we thought hard about what job titles to use—didn't want to bucket people into researchers & engineers. Alan Kay advised that they used "Member of Technical Staff" at Xerox Parc, we loved & adopted it. Recently have seen many companies doing same—very cool!
