[Michael Strong @flowidealism]

Wow, a pretty damning article with diverse lines of evidence.

[William Huang @amiwilliamhuang]

happy to have posttrained what was known as Rizz-65B up until an hour ago

[Stanford University @Stanford]

The most important briefings of the day.

Karl Deisseroth, professor of bioengineering and of psychiatry and behavioral sciences, shares the news of his Nobel Prize with his kids.

[Pranav Ravella @pranavravella]

From dropping out of Stanford with @RonNachum and @AryaGrayeli to building a generational company with the most incredible people, I couldn't be prouder of everyone at @sapienai.

I'm so excited to show the world what we've delivered for our customers.

We’re hiring. Come join us: https://t.co/d7Jh9vd9FI

[Ron Nachum @RonNachum]

Sapien is the engine behind the world’s most important companies.

Today, we’re announcing our latest fundraise at a $180M valuation.

We build systems that learn how complex businesses work, enabling financial & operational optimization for the people who build everything else.

[Prakash @8teAPi]

Just to take a step back here, Levent had the highest GPA at Harvard, won the top undergrad math research prize and most frequently collaborates with a Fields Medalist.

We don’t have enough human mathematicians to ask questions to AI and spend time understanding the results

[levent @__alpoge__]

hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final

((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

[Quentin Romero Lauro @Qromerolauro]

We just built Figma for Claude Code

This is not a demo or waitlist. Try it today.

[Niall Kehoe @Niall_Kehoe]

Less headaches, less effort.

[Sylvian @TheSylvianAI]

Never fill a form by hand again.

[Aaron Epstein @aaron_epstein]

The Sylvian founders have an extraordinary ability to recruit the smartest experts in the world to their competitions, generating 1B tokens per week of expert tool use data.

Congrats on the launch @amiwilliamhuang @Niall_Kehoe!

[Y Combinator @ycombinator]

Sylvian (@TheSylvianAI) creates tool use environments and gathers expert tool use data (VSCode, Excel, etc.) for LLMs.

They already have 4,500+ experts, from IMO Golds to MIT/Stanford PhDs, producing data at 1B tokens/wk.

[Niall Kehoe @Niall_Kehoe]

More details and the full results can be found here: https://t.co/h6rzIRYHOZ. For now, the best quantitative finance teams were able to clear the performance of the best AI models. Quant finance continues to be one of the most difficult domains to master.

[Niall Kehoe @Niall_Kehoe]

Can AI replace humans in quant finance?

We recently ran a competition for 2k+ quant finance students and professionals from Imperial College London, UC Berkeley, MIT, Point72, and more. Then, asked SOTA AI models to attempt the same tasks: Quant Research and Live Trading.

[Niall Kehoe @Niall_Kehoe]

On the trading side, we asked models to write algorithms to trade securities for basketball game outcomes. We then simulated virtual games for them to trade against human/AI-developed models. Qwen3, Sonnet 4.5, and GPT-5-Codex were the only models with positive PNL on average.

[semi @SemioticRivalry]

On the latest round of insider trader or degen gambler, we have a totally fresh Polymarket user who bought the Venezuelan opposition leader from 5% to 40% to win the Nobel Peace Prize, 1 day before the announcement. Tomorrow we'll know if this person is an idiot or has great info

[Renaud Foucart @RenaudFoucart]

Economists: people don't understand marginal tax. If your tax rate increases above £100,000, you don't suddenly lose money when you earn £100,001

UK tax system: hold my beer

[Justine Moore @venturetwins]

The Stanford experience

[Ron Nachum @RonNachum]

Can AI run a company? We raised an $8.7M seed led by @generalcatalyst and top tech & finance angels to prove it can.

At @sapienai, we’re building autonomous financial analysts redefining enterprise finance—already saving thousands of hours and catching multi-million-$ mistakes

[Niall Kehoe @Niall_Kehoe]

Tired of writing tests? We've automated it for you using Llama 3.1 🥳

[Ameya Jadhav @ameyajadhav_]

🎉 We won “Most Interesting Technical Achievement” at the @spc x @AIatMeta hackathon!

@nahuum_maru, @w41tz, @Niall_Kehoe, and I built TestNinja, an autonomous agent platform for robust and context-aware test generation in GitHub CI/CD pipelines.

👇 Here's our demo
