Still from the movie "Upstream Color". A woman and a man looking at each other, clear dusk sky in the background, silhouettes of birds in the sky.

I love sci-fi, and I read and watch a lot of it.

Companies die from a lack of cash, which in your average SaaS company means a lack of product market fit.

For anyone interested in fine-tuning or aligning LLMs, I’m running this free and open course called smol course. It’s not a big deal, it’s just smol.

It’s an interesting ranking, but most of Spain’s score apparently comes from having a great Internet speed and some regulations.

Speaking of this, the original MapReduce paper contains what I imagine are the first versions of Borg, Jupiter, and Colossus.

Lo que no sabemos nos cuesta demasiado

Lo que no sabemos nos cuesta demasiado

El recibo de la opacidad lo pagamos juntos. 💸

Cada contrato oculto, cada euro malgastado, cada acción en la sombra engordan una factura que aceptamos sin rechistar. Pero no tiene por qué ser así.

Podemos investigar más. Informarnos mejor. Exigir cuentas. Incluso aliarnos para cambiar esto.

Reviewing BigQuery technical info, I see that Borg orchestrates the communitcation between Dremel, Jupiter, and Colossus.

But what about Galactus???

Question from Leo on Twitter:
It doesn’t interpolate, does it? 

If I ask “What color is a Gropy?”, and we had 100 labellers say it’s blue and 100 labellers say it’s yellow, it’s going to randomly say blue or yellow - but never “It’s a debated question, some say blue, some say yellow”. Right?

Answer from Andrej:
Excellent question and yes exactly, it responds with blue or yellow with 50% probability. Saying “It’s a debated question, some say blue, some say yellow” is just a sequence of tokens that would be super unlikely, it doesn't match the statistics of the training data at all.

I especially liked this answer.

Text from Andrej Karpathy in Twitter: People have too inflated sense of what it means to "ask an AI" about something. The AI are language models trained basically by imitation on data from human labelers. Instead of the mysticism of "asking an AI", think of it more as "asking the average data labeler" on the internet.

Few caveats apply because e.g. in many domains (e.g. code, math, creative writing) the companies hire skilled data labelers (so think of it as asking them instead), and this is not 100% true when reinforcement learning is involved, though I have an earlier rant on how RLHF is just barely RL, and "actual RL" is still too early and/or constrained to domains that offer easy reward functions (math etc.).

But roughly speaking (and today), you're not asking some magical AI. You're asking a human data labeler. Whose average essence was lossily distilled into statistical token tumblers that are LLMs. This can still be super useful ofc ourse. Post triggered by someone suggesting we ask an AI how to run the government etc. TLDR you're not asking an AI, you're asking some mashup spirit of its average data labeler.
