in my experience, AI is excelling at most technical work except for ”what is the right next problem to work on”. for now, humans still have a noticeable advantage there

oh yeah. Sol is reliable and for normal work. Astra is for galaxy brain stuff. like when you're stuck and need someone to take 10 steps back and show an alternative path

astra may be my favorite model now. it's a very weird one

Okay so I've built a new Atlas, this time it lets you explore the conversations on Bluesky over the past 7 days graphically. It should update every ~6 hours and help you navigate the information environment that exists on here. I've learned a LOT about what people do here today... atlas.jazco.dev

you also have to readjust Astra towards fidelity with whatever you initially got out of it. it has a very unhealthy bias towards execution so you need to get it back to thinking deep about stuff

currently my Astra is managing Sol 6’s, hard to say how they’re different since i’m not using them directly haven’t tried new Opus yet.
210
dan @danabra.mov · 23/09/2026
my problem with it was i asked it to get into implementation too soon. it’s making too big decisions (often wrong) too early in execution mode
160
dan @danabra.mov · 23/09/2026
my current rating: - 5.6 Sol: dependable workhorse, sound judgment, gets through the slog and stays on rails - Fable 5.1: bulldoze through hard problems that Sol gets stuck on or fails to see bigger picture - Astra 6: deeply understand the big picture, fundamental in-place reshaping, overseer

do NOT let Astra near code until it adopts a personality of domain nerd with high bar for excellence and taste and ideally give it something that already does what you want end-to-end but maybe badly. it’ll fix it
1270
dan @danabra.mov · 23/09/2026
ok i take it back Astra is good how to work with it: 1. get it to deeply understand what needs to be built. not “plan“ but like get it to be a domain nerd 2. only THEN, give it a usable past sloppy attempt and ask for excellence 3. ask it to use Sols for coding so it stays on strategy and taste

re last point, can somebody from frontier labs please finally drill polya’s “how to solve it” into the models thinking trace habits? “we have to shift our position again and again“ is so obvious to how humans work but models refuse to do that because they race towards the finish line! so annoying
Four phases

edit
Pólya begins with a two-page checklist that identifies four phases to solving a mathematical problem:[4]

Understand the problem.
Make a plan.
Carry out the plan.
Look back.[5]
He emphasizes that the divisions between phases are not rigid, and it is important to be flexible in one's approach:

Trying to find the solution, we may repeatedly change our point of view, our way of looking at the problem. We have to shift our position again and again. Our conception of the problem is likely to be rather incomplete when we start the work; our outlook is different when we have made some progress; it is again different when we have almost obtained the solution.[6]

5.6 Sol is my guy. best model in town right now imo. maybe not the cleverest but at least it’s relatively dependable. especially if you give it a little bit of structure on how to work

dan @danabra.mov · 21/09/2026
that said Astra seems great in the first five minutes. like analyze this and that, propose how to think about the fix etc. just can’t actually let it do the work beyond a couple of steps

dan @danabra.mov · 21/09/2026
if you leave Sol overnight with a well-chosen goal, you might wake up to it done or at least see decent progress on it. if you leave Astra overnight, you‘ll wake up to it being 20% through three different misrepresentations of your goal

dan @danabra.mov · 21/09/2026
wish i could refund 95% of my Astra usage. keep giving it a chance and it fumbles but it spends tokens way faster than Sol. a very disappointing release for actual implementation work

“clearing the fog“ is maybe not a great analogy because it implies there’s one concrete way something works. whereas it’s more like there’s a bunch of facts, and some are considered ”interesting if true (or false)“ because the hope is that the path reveals new path systems. a weird road helps less

dan @danabra.mov · 19/09/2026
my uninformed mental model of AI proofs in mathematics is that they’re like lighthouses in the fog. the fog is still there, and clearing the fog is the primary value of the discipline. the lighthouses give a bit of an orientation but don’t clear the fog on their own.

a reply from Prof. Mantova! news.ycombinator.com/item?id=4976... honestly this is the best kind of outcome i‘m hoping for with amateur-driven AI proofs: maybe they aren’t usable directly but can offer a couple of nudges that help the mathematicians uncover the actually interesting connections
xworld21 31 minutes ago | unvote | parent | context | flag | favorite | on: I vibed a proof of Conway's conjecture

Vincenzo (Mantova) here: yes, I have been reading bits and pieces of the proof and I can say for sure that the method is sound, at least for the first half (power series with real exponents). I haven't even tried reading the part that mentions the Cantor-Bendixson rank yet, although given how the rest went, I'd be really surprised if there's a problem there.
As with most interesting proofs, the number of core ideas is actually small, I'd say two for the real exponents, and presumably a third idea for lifting up to omnific integers. I have been redoing the real exponents part of the proof going on the ideas only, and with a few smarter choices, I am converging on something very short. And I mean very short, which is amazing. I didn't think the answer would be this close: it 'just' needs looking at the problem from the right angle, and also make a fairly bold guess at the outcome.
Dan's current proof is of course much longer. Between the fossilized ideas that Dan mentions in the post and the formalisation of previous results, there's a lot of cruft that inflates the proof but does not really help understanding what is going on. Luckily the word 'derivation' pops up early, otherwise it would have been very challenging to wade through the lemmas to find the important points.

heh i like this
gbjcantab 1 hour ago | next [–]

For some reason, this approach makes me think of the difference between “wizardry” and “sorcery” in some fantasy magic systems. The magic of “wizards” is fundamentally based on a deep study and understanding of arcane things, perhaps assisted by some (necessary or helpful) tools of great power. “Sorcerers” summon supernatural beings and are able to control them, cajole them, and protect themselves and others against them (with more or less success)... but the actual desired magical effect is performed by those beings.
Computing has historically been a field of wizardry. It's... interesting (?) to see so many people pushing so hard in the direction of sorcery, and in fact applying that sorcery to other fields, in which they themselves aren't quite able to validate whether the spell worked or not.

Heh, I like this. but it should be pointed out that from the other point of view, software developers were the supernatural beings (dare I say demons), which the sorcery of a good project manager could tame (with more or less success) to perform the desired magical effect
