Whoops, chose the wrong week to share our paper…
Something about someone named Navier and Stokes????
But hey the code is out now! Go play with latent identification probes 🤾
💻 Code: github.com/bayazitdeniz/late…
1/🚨 New paper #emnlp2026
Do multilingual #LLMs work in English? It depends on how you ask. In "Lingua Franca or Probing Artifact?", we probe the same hidden states with three latent language identification methods and get different answers. 🧵👇

Footage published by Iranian media today shows damage to Chehel Sotoun Palace, a Safavid-era cultural landmark located in the historic centre of Isfahan, following air strikes in the area.
Two more landmarks, Golestan Palace and Tehran Grand Bazaar, sustained damage last week.

Happy to share that our paper “Mixture of Cognitive Reasoners: Modular Reasoning with Brain-Like Specialization” (aka MiCRo) has been accepted to #ICLR2026!!🎉
See you in Rio 🇧🇷🏝️
🚀 Excited to share a major update to our “Mixture of Cognitive Reasoners” (MiCRo) paper!
We ask: What benefits can we unlock by designing language models whose inner structure mirrors the brain’s functional specialization?

The Iranian Foreign Minister will not be attending Davos.
Although he was invited last fall, the tragic loss of lives of civilians in Iran over the past few weeks means that it is not right for the Iranian government to be represented at Davos this year.

⚠️ Update: Internet connectivity continues to flatline in #Iran despite a minor short-lived bump in access earlier today, when new reports of atrocities emerged.
As the shutdown enters day ten, confusion surrounds whether the regime intends to restore service soon, or at all.

Great to see our "From Language to Cognition" work featured in @mordecwhy's latest piece on language models and the brain. Glad to contribute to the conversation!

I really don't think most people understand the scale of the horror that has unfolded in Iran this last week.

⚠️ Update: #Iran has now been offline for 120 hours.
Despite some phone calls now connecting, there is no secure way to communicate and the general public remain cut off from the outside world.
What footage makes it through shows extensive use of force against civilians 📵
The fact that this is an AI’s researcher’s reaction to someone’s lived tragic experience - and what millions of people are going through right now - is deeply concerning. If you’re incapable of empathy how can you be trusted to build technology meant to benefit humanity?

Imagine the profound lack of character - that your first instinct is to use tech to prove you’re incapable of empathy for someone’s lived experience. block this midwit

36 hours of internet blackout!
#IranBlackout
⚠️ Update: It's now 8:00 am in #Iran where the sun is rising after another night of protests met with repression; metrics show the nationwide internet blackout remains in place at 36 hours, severely limiting Iranians' ability to check on the safety of friends and loved ones 📵

The people who gave humanity these wonders deserve better governance, more freedoms.
The gorgeous architecture of Iran. ✨

While we’re obsessed with America’s petty fights and disagreements, the people of Iran are in a fight for their freedom.
I have so many amazing friends from this region — in fact, some of the best, most fun and joyful humans I’ve ever met — that I’m rooting deeply for their country to be free…
…and what a thrill it will be to experience the homeland they talk so lovingly about. 🙏

⚠️ Update: It has now been 24 hours since #Iran implemented a nationwide internet shutdown, with connectivity flatlining at 1% of ordinary levels. The ongoing digital blackout violates the fundamental rights and liberties of Iranians while masking regime violence ⏱
