For @ForeignPolicy I wrote about Iran and why nuclear uncertainty is bad for regional stability (link below). Unclear diplomatic priorities + backlash against the IAEA w/in Iran are taking us down a dangerous path.

China is bypassing U.S. export controls on GPUs, but how?

In my latest paper, "Whack-a-Chip," we provide the first public evidence of how China is using advances in ML to make old chips useful for SOTA results.

Delighted to see the latest from @BerkeleyRisk w/ @Ritwik_G and @LPWalkr in the wild. Using the recent release of Tencent's Hunyuan-Large model, the paper begs the question as to whether hardware-oriented #AI #export controls are doing what policymakers want...

A few takeaways from my recent piece for @carnegienpp about the risks of a more opaque Iranian nuclear program (and some cautionary lessons from the Iraqi experience)

[Jane Darby Menton @JDMenton]

For @CarnegieEndow I wrote about the perils of nuclear ambiguity, and what Iran (and the world) can learn from the saga of Iraq's nuclear program. TLDR: playing political football with international oversight rarely ends well for anyone: https://t.co/7o1kbypOb7

Bigger isn’t better, but major AI policies (like the Biden EO) focus only on model size & compute. However, models are useless without data! In our latest work, we highlight the need for data-centric AI policy and reveal the shortcomings of the status quo. https://t.co/Qkt3VhGy2w

@Ritwik_G @HigginbothamA Highly recommend the Challenger Decision by Diane Vaughan as well

Thread 📜 OTD in 1963, the US and Soviet Union established the "Washington–Moscow Direct Communications Link" or hotline. At the time, the @Guardian reported that this step would be a "small, but useful, measure of arms control" especially in light of the #CubanMissileCrisis.

[Jane Darby Menton @JDMenton]

As the G-7 convenes in Hiroshima this weekend, I wrote a piece for @ForeignPolicy about the city's enduring message—and the country's challenging security environment.

Can't wait for this conversation with some of the best and brightest in the #AI-#cyber and #governance communities from @StanfordCISAC @Google @OpenAI @Anthropic on the sidelines of @RSAConference and sponsored by @BerkeleyRisk and @UNIDIR. Join us on April 24!

[Berkeley Risk and Security Lab @BerkeleyRisk]

New from BRSL's @areddie89 : "Why the alarm over Russia’s use of hypersonic missiles in Ukraine is misplaced". Dr. Reddie examines the two types of alarmism in the response to the recent Russian use of hypersonic Kinzhal missiles in Ukraine. Read it now: https://t.co/9PSgQQtNgJ

📣 NEW: With support from @StateDept's Bureau of Arms Control, Verification, and Compliance, we're releasing the product of a year's worth of research into the strategic stability risks posed by integrating AI into NC3.

@BuchananLiz Which book is this?

[Institute for Security and Technology @IST_org]

The Office of Strategic Capital @DeptofDefense was established this month to boost defense-tech investment. IST’s @LPWalkr & Alexa Wehsener write, “the true test of the well-intentioned office will be whether it has sufficient impact on the American innovation ecosystem.”

[L. Walker @LPWalkr]

A new piece from Alexa Wehsener and I, where we discuss the implications of the new Office of Strategic Capital:

The NSS mentions enhanced crisis communications with China - good! But it's also been a longtime priority that has thus far failed to have regular impact.

Check out which 🇺🇸🇨🇳 links have been attempted in @LPWalkr and my "Atlas of Crisis Comms": https://t.co/EOJj1ZL6fQ

Over the last month, team IST participated in #NPTRevCon, joining international efforts to reduce the risk of nuclear conflict. 1/8
