GPT-5.5 Instant is starting to roll out in ChatGPT. It’s a big upgrade, giving you smarter, clearer, and more personalized answers in a warmer, more natural tone. And it's also more concise, which we heard you wanted. We think you'll love chatting with it.

To sum up; Anthropic, OpenAI, Google, Microsoft and xAI all have new pre-release screening agreements with CAISI. We don't know the details of the new rules yet. I assume they will be announced with the AI executive order and the AI policy memo, both of which we may get today.

According to CBS, citing defense officials speaking on condition of anonymity, the USS Truxtun (DDG-103) and USS Mason (DDG-87) transited the Strait of Hormuz today into the Persian Gulf under constant threat from Iranian fires. Per the report, both destroyers transited while being targeted by Iranian drones, missiles, and small fast-attack craft during the transit. They were supported by Apache helicopters and other aircraft throughout the barrage of Iranian attacks. Additionally, per the report, no projectiles struck the ships during the engagement.

In a call with reporters just now, Adm. Brad Cooper of @CENTCOM says Iran has opened fire on U.S. warships and commercial vessels today, but declines to say whether the ceasefire between the U.S. and Iran is over. U.S. forces returned fire and destroyed some Iranian small boats.

🚫 CLAIM: Iranian state media claims that Iran's Islamic Revolutionary Guard Corps hit a U.S. warship with two missiles. ✅ TRUTH: No U.S. Navy ships have been struck. U.S. forces are supporting Project Freedom and enforcing the naval blockade on Iranian ports.

"A szelekció kiterjedt volt, csak eddig nem láttuk a jeleit” – nyilatkozta a Qubitnek Ali Akbari, a Harvard Egyetem genetikusa, aki az archeogenetika egyik vezető alakjával, David Reich-kal vizsgálta a szelekció emberi genomra mért hatását.

Átfogó kutatás bizonyítja, hogy nem állt meg és nem is lassul az ember evolúciója A természetes szelekció sokkal fontosabb szerepet játszott az ember elmúlt 10 ezer éves evolúciójában, mint korábban gondoltuk, derítették ki a Harvard kutatói.

This is a good explanation of why the gap between open and closed models is larger than it appears in benchmarks. I would add in that current open models are also more fragile than closed: they handle out-of-distribution problems far less well & have lower emergent capabilities.

Update on Erdős Problem 1196: In joint work, we refined and adapted the proof method from GPT-5.4 Pro to give proofs of several additional problems. This includes another 60 year old conjecture by Erdős, Sárközy, and Szemerédi. A proof is valued not just by the problem it solves, but by what new avenues it opens up. This is perhaps one of the first examples of an AI-generated proof having downstream impacts, which we are still exploring. We are announcing the result today at the Future of Mathematics Symposium (see links below)

The US will withdraw about 5,000 troops from Germany, about 7% of the total force in country. The withdrawal will be completed in the next 6-12 months, announced just a days after President Trump spoke with Putin and the US spars with Germany and Europe over the Iran War.

This morning the Department of War announced it has entered into agreements with SpaceX, OpenAI, Google, NVIDIA, Reflection, Microsoft, and Amazon Web Services to deploy their advanced AI capabilities on the Department's classified networks for lawful operational use.

GPT-5.5 had a slightly higher average performance than Mythos on UK AISI's "The Last Ones" multi-step cyber-attack simulation (see the chart below). GPT-5.5 completely solved this simulation in 2/10 attempts (not 1/10 as previously reported by OpenAI). Mythos solved it in 3/10 attempts. One would assume that GPT-5.5-Cyber (announced today) would do even better on these kinds of tasks than GPT-5.5.

Earlier this month, an Erdős problem that had been open for 60 years was solved with help from GPT-5.4 Pro. What happens now that AI is getting good at math? OpenAI researchers @SebastienBubeck and @ErnestRyu join host @AndrewMayne to explain what changed and what it could mean for the future of research.

(Reuters) - The United Arab Emirates said on Tuesday it quit OPEC and OPEC+, dealing a heavy blow to the oil exporting groups and their de facto leader, Saudi Arabia, at a time when the Iran war has caused a historic energy shock and unsettled the global economy. The stunning loss of the UAE, a longstanding OPEC member, could create disarray and weaken the group, which has usually sought to show a united front despite internal disagreements over a range of issues from geopolitics to production quotas. OPEC Gulf producers have already been struggling to ship exports through the Strait of Hormuz, a narrow chokepoint between Iran and Oman through which a fifth of the world’s crude oil and liquefied natural gas normally passes, because of Iranian threats and attacks against vessels. But the UAE exit from OPEC represents a big win for U.S. President Donald Trump, who has accused the organisation of "ripping off the rest of the world" by inflating oil prices. Trump has also linked U.S. military support for the Gulf with oil prices, saying that while the U.S. defends OPEC members they "exploit this by imposing high oil prices". The move came after the UAE, a regional business hub and one of Washington's most important allies, criticised fellow Arab states for not doing enough to protect it from numerous Iranian attacks during the war. Anwar Gargash, the diplomatic adviser for the UAE president, criticised the Arab and Gulf response to the Iranian attacks in a session at the Gulf Influencers Forum on Monday. "The Gulf Cooperation Council countries supported each other logistically, but politically and militarily, I think their position has been the weakest historically," Gargash said. "I expect this weak stance from the Arab League and I am not surprised by it, but I haven't expected it from the (Gulf) Cooperation Council and I am surprised by it," he said.
