Are you using open models on a regular basis? If yes, I’d love to hear about it!
- what’s your use-case?
- local or through an inference provider?
- how has the experience evolved over time?
- anything you miss from the closed models, if you’ve used them?
Would appreciate reposts for visibility 🙏

A workforce trained to normalize generative AI is a workforce that *will not be able to understand* people talking about creativity and pride in gaining skills and the value of their labor. It'll be alien to them.

Was... someone... *watching me* thrash around in my early MA thesis writing? 🫣
In the early months of a research project. Reading chaotically, joyfully. Scrawling ranty paragraphs, most of which will never get past my notebook. It’s the ecstatic scholastic.
Even if this phase could be compressed or automated, why would you want it to be?

Abbe Lowell's argument that DOJ is not entitled to presumption of regularity in Don Lemon case consists of:
1) A page on irregularity in this case.
2) A page on irregularity in MN.
3) Other adverse rulings in MN.
4) One page plus TWO PAGE footnote on similar rulings nationally.

Can't say it enough, if you are going to build ANYTHING, you are going to be criticized much more than you will be praised. Do not be deterred. Build what you want to exist. Find your people and seek their counsel. Keep it moving.

I’m behind on this episode, but this bit of transcript is pretty standard. As is often the case, the “tolerance for ambiguity” (per Nate) is… bafflingly selective.
Students expected to wait for years for it all to make sense, but a single problem that hasn’t been fully pre-digested? Never. 🤪

I listen to these podcasts because I really do find learning sciences research interesting… but, while I think this is super vivid framing, I have two arguments against thinking of teaching and learning in this way… (🧵 1/8)

We don’t need to keep engaging in false binaries: we don’t have to use living conditions as excuses for not teaching. Inquiry lessons are not antithetical to teaching kids facts. And expecting a tolerance for ambiguity isn’t a reason to deny kids meaningful connections between school & life (8/8 /🧵)

I didn’t know this wrinkle either, but…
“Cognitive offloading” is nothing new. We’ve been pawning our brain power off on tools and OTHER PEOPLE for as long as we’ve been around. Not surprising, then, that it’s such a reflex when new inventions come along.

(holy hell I was slightly shocked to learn in that 2021 paper that "ancient Romans trained slaves to remember legal information so that they could be called on in a public debate". The history of human knowledge is always also the history of oppression. ANYWAY, BACK TO NERD STUFF)
