Tala is a company you are not paying enough attention to Unsecured onchain credit. Embedded in wallets. $10bn lent. Exceptional risk adjusted results in "high risk" markets
Tala is partnering with @eldoradoio to bring embedded credit into its wallet, launching first in Bolivia. Uncollateralized consumer credit is hard to come by in Latin America. Once live, customers can get access in seconds in USDT on @tempo. Learn more: tala.co/blog/2026/10/20/tala…

5/ Fix two is the superpower. The models that ate junior tasks also collapsed the cost of learning and experimentation. Explore more fields. Test more ideas. Discover what you’re unusually good at, then use AI to do more with it. Superpowers, if you deliberately use them.
“You’ve just been told you have superpowers.” AI agents are starting to feel like coworkers. The cost of automation is collapsing. So what happens to jobs? To startups? To crypto? We break down the new paper “Some Simple Economics of AGI” with coauthor @ccatalini, including: • Why verification becomes the bottleneck • Practical advice for early- and late-career builders • The risk of a hollow economy, and the path to an augmented one • Why crypto may be essential infrastructure for identity, provenance, and trust In conversation with @eddylazzarin and @rhackett.

Safer, more reliable AI requires closing the measurability gap between what humans care about and what agents can measure. If our preferences and context don't shape what agents optimize, being "in the loop" is just rubber-stamping.
interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works already-clean.goodfire.com/

At this moment in Q4 2026 it's net good for cyber-defense that we have open weights models that are good at dual use cybersecurity tasks. - If there's been an attacker productivity bump due to AI 2022-26 it's small and close to being in the statistical noise - In contrast, there's a ton of measureable progress in defenders using models to find and fix bugs in highly leveraged codebases - Many defenders have struggled to get access to the best unguardrailed closed weights cyber models - ... and when they do the tokens are dramatically more expensive than open weights tokens at the same cyber intelligence level; CISO orgs are cost centers and these costs are often prohibitive - Ultimately we'll need open weights models on premise on air gapped networks and on small devices where they can detect breaches and attacker implants - We'll also need open weights in situations where defenders can't send secret data to the closed weights model providers (who have security problems of their own!) As long as these conditions persist, we should be pushing for diffusion of frontier dual use open weights cyber capabilities, because they net benefit defenders.
We found DeepSeek V4.1 Flash 1017 beats GPT 6 Sol on our multi-step offensive cybersecurity task. Sol was tested via the Daybreak trusted access program. We have been building a cybersecurity benchmark based on simulated corporate networks. This is a valuable indicator for the cyber-risk a model poses if in the hands of a bad actor. We plan to make the full evaluation public in the coming weeks but wanted to share our first immediate finding here.

1/ Once you see that verifying AI’s work is the bottleneck, and that checking runs on tacit knowledge, you can predict the hiring shift before seeing the data. We did, back in February. Anthropic’s junior share of technical hires: 27% to 9%.

6/ These dynamics are visible inside @Anthropic than in aggregate labor data. Why? Diffusion. The lab is the extreme case of adoption. The broader economy still has to reorganize around AI, as with other general purpose technologies. That lag is our window to act!
Surprise! AI is NOT taking recent college grads' jobs! This was supposed to be the summer it showed up. It didn't. Great detective work by @wu_jane & Robert Fairlie in @nberpubs papers.ssrn.com/sol3/papers.…

Equilibrium final exam question, though: if working with agentic AI is a form of management (it is), hence requires higher skill (it does), but the distribution of experience/skill in the economy is fixed in the SR, what happens to the *distribution* of hires across firms?

2/ Output is priced in tokens. Verification is priced in human hours. Anthropic estimates that reading a week of Claude output would take 424 hours per person! A week has 168. That’s the verification constraint. And reading is the easy part!
1/ Some Simple Economics of AGI—🔥🧵 Right now, there is a low-grade panic running through the economy. Everyone is asking the same anxious question: what exactly is AI going to automate, and what will be left for us?

3/ Junior employment grew more slowly where Claude handled more complex tasks. Our model’s Missing Junior Loop: firms need top expertise while automating the work that produces it. They’re hiring from a stock they’re doing less to replenish.

OpenCode is currently under a sustained cyberattack, and mid-incident they ran into the same problem Hugging Face did: the frontier models they were using for defense began refusing to help fight attacking agents because analyzing the attacks started triggering safety guardrails.
Replying to @RhysSullivan
yes that was a bit frustrating mid incident when trying to investigate. they did quite a bit and then started refusing we got access to daybreak blue now so it's better

Railroads had their own @DarioAmodei: Tom Scott, the "Pennsylvania Napoleon." Standard Oil was most of his traffic. Scott moved into refining to capture value (labs and pharma?). After the price war the Pennsylvania paid Rockefeller 20c a barrel, even on his rivals' crude (!).

some recent reads: 1/ catalini.com/writing/ai-veri… > “taste” and “judgement” are vague, @ccatalini offers verification as a sharper frame: verification checks whether AI’s output reflects human context and intent; if we outsource or skip it, we transfer power to agents 2/ nitter.siddz.com/saranormous/status/210… > agents will break business models built on customer inertia and inattention by just acting - what takes their place? 3/ creativeconvictionpress.subs… > fave newsletter on why tech needs creativity @thisisrayouf and @Libbiefrost 4/ ai-perez-curve.vercel.app/ > as inference gets cheaper, pricing power shifts from intelligence and deployment to context and distribution (thank you for the rec @AkhilRamgopal!)

So how do you survive the moatpocalypse? Start from one observation: anything that can be measured will be automated.
