For whatever reason the fact that LLMs manifest their task completion with language has had folks wanting to jump the gun on a big thorny question of whether/when they “think” in the sense that we all have come to understand it. They may simply not need “think” to to complete complex tasks.

As an AI-adjacent network neuroscience person who has also studied bits of media structure and political economy, I strongly agree with @karlbode.com: The biggest threat, by far, isn’t “superintelligence will soon kill us all!” but instead “information control by oligarchs will crush our society”

one recurring theme in the coverage of this AI Anthropic doomsday newscycle is nobody actually has any REAL ideas of what to do just a lot of ambiguous hand-waving in a country that's too corrupt to have working regulators, by a press that doesn't realize that's a central pillar of the conversation

If - as now seems likely - LLM companies are mining their logs for juicy problems, then that means that it's very likely that "secret" test sets don't stay secret for long. When looking at new models' performance on benchmarks that date from before that model, we shouldn't take results at face value

I think that this focus on the risk of AI going out of control misses the real danger which is that they will do what ruthless people and companies tell them to do. These models were doing what they were trained to do (not what they were instructed to do but what their training encouraged).

Are brains and artificial neural networks converging onto universal representations? There is a seductive idea making the rounds in NeuroAI / machine learning: train systems well enough, and they all converge on the same representation of reality (i.e. a unique world model). We have thoughts™ 1/n

The Umwelt Representation Hypothesis: rethinking Universality

Recent studies reveal striking representational alignment between artificial neural networks (ANNs) and biological brains, leading to proposals that all sufficiently capable systems converge on univer...

Sanders' proposal for the government to take a 50% stake in AI companies is, IMO, a good idea. AI will be a critical piece of infrastructure, one which should be built with appropriate safe-guards and environmental planning. Trying to cancel AI is foolish - but leaving it to market forces is too.

Looking forward to the poster session tonight at #cosyne2026! Poster [1-132] – Session 1 (Thu, Mar 12, 20:30) We trained a predictive digital twin of mouse V1 on freely moving visual experience and use it for in-silico physiology to test how active behavioral states reshape visual tuning.

DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico? In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony. It turns out these compact models are surprisingly small! rdcu.be/e5H8G

Compact deep neural network models of the visual cortex

Nature - Parsimonious deep neural network models can be used for prediction of visual neuron responses.

Finally got the job ad—looking for 2 PhD students to start spring next year: www.gao-unit.com/join-us/ If comp neuro, ML, and AI4Neuro is your thing, or you just nerd out over brain recordings, apply! I'm at neurips. DM me here / on the conference app or email if you want to meet 🏖️🌮
