Who knew @SouthPark was so prophetic? youtube.com/watch?v=sDf_Tg… If you want to listen to the songs it made... flowmusic.app/session/90d9d4…

This is a farce. To claim "more guardrails" is frankly unbelievable. Why would @AnthropicAI be called a supply chain risk but then @OpenAI gets a contract with stricter conditions. If guidelines are stricter then what's the claim? DOD killing your competition for you?

Yesterday we reached an agreement with the Department of War for deploying advanced AI systems in classified environments, which we requested they make available to all AI companies. We think our deployment has more guardrails than any previous agreement for classified AI

Very impressive, but also wrong. There's 2 mistakes in the first physics problem on the LHS. It did the derivative wrong, but fixed its mistake with another mistake! (better explanation in alt text) ChatGPT looked at the end, not the answer.
$Here's the full correct solution. Nano banana's mistake was in the time derivative. It added an extra -i. Interestingly, it looks like the mistake is like it is trying to do some chain rule within the exponent. Probably since it first converted the exponents to e^{ -i ( px + Et) / \bar{h} }. Perhaps it hallucinated the equation e^{ -i ( px + iEt) / \bar{h} } instead$
$Here I'm using Nano's answer and we see that it incorrectly multiplies the i's. Remember i*i = -1 It *should* have gotten the answer iE \Psi, which would have been incorrect, yet it fixed its mistake! To write it another way we can write like -1 * i * i * i | since -i = i * -1 = -1 * (i * i) * i | collect = -1 * -1 * i = i$

Gemini Nano Banana Pro can solve exam questions *in* the exam page image. With doodles, diagrams, all that. ChatGPT thinks these solutions are all correct except Se_2P_2 should be "diselenium diphosphide" and a spelling mistake (should be "thiocyanic acid" not "thoicyanic") :O

My 9yo got it straight away. GPT5 on ChatGPT gets it totally wrong.

Unknown to most people, there isn't just one physics. The history of science itself gives a positive answer to this question. Which is why many are wary of world models through scaling alone. Its known to be not enough.

Can an AI model predict perfectly and still have a terrible world model? What would that even mean? Our new ICML paper formalizes these questions One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧵
