@chamath I don't think this applies to consumption based model which is how they charge business for API usage? It would only apply to consumer subscriptions.

A few things: (1) This isn’t the bad thing people think it is. (2) Thank you to all the VCs whose money is subsidizing this largesse to customers (we are one). (3) Not knowing the data, I can still guarantee that there is a huge bi-modal distribution on usage happening in Claude. A small group of super cracked devs use infinite amounts while devs at traditional companies use some/little. Overall, on a time-based cohort basis, I suspect positive margins are largely in tact despite a deep J-curve acquisition loop on some users (ie the super users). Anyways, as the CEO of 8090 who has to pay the bills, I thank everyone funding Anthropic for their largesse because we were already spending way too much on this stuff without the equivalent pull through ROI (ie $1 spent on AI should equal more than $1 of new revs), so every subsidy helps.

@dee_bosa @DavidSacks the whole idea that we can/should slow down china's progress in AI is both dumb and impossible. We have seen that repeatedly with technology. We should spend the energy focusing on speeding up our own progress instead!

tough look for Jensen and @DavidSacks and everyone arguing to keeping the China market open to older US chips (myself included) The case against export controls was always: sell to China so theres no market for their own. But they're doing both, plus stealing the software too through distillation. The case for selling chips into China gets harder by the day. Nvidia reports tomorrow and next Deepseek model anticipated soon.

@EthanChoi7 @AnthropicAI the real lesson here is that counting on capabilities of the raw model is not a sustainable business model! Either you build strong products that enterprises/users want to use (which anthropic has done for coding), or your margin will eventually shrink to a commodity offering.

Echoes of past behavior during industrial era, with Chinese copying U.S. designs and manufacturing cheaper versions to flood the market. Electric cars, solar panels, and now our LLMs. Open weights as a distribution weapon to blunt U.S. influence and control over the most important thing right now.. AI and ability to print intelligence

We’ve identified industrial-scale distillation attacks on our models by DeepSeek, Moonshot AI, and MiniMax. These labs created over 24,000 fraudulent accounts and generated over 16 million exchanges with Claude, extracting its capabilities to train and improve their own models.

I've spent the past week anxiously following the news in Iran. Protests in the last few days have escalated and taken a dark turn. Thousands have been killed or arrested, and the government has cut off phone and internet access, leaving tens of millions of people unable to communicate.  My heart goes out to the innocent people who are affected by all this, including Iranians who live in the US and elsewhere. ❤️ Many are attempting to continue their studies or work and get through their daily lives under the immense pressure of wondering what's happening in Iran. Some who are financially supported by their families in Iran are in need now. Some may have lost friends or family members. Many can’t even contact their family members to know if they’re safe. There are others who might have traveled home to Iran for Xmas and are now stuck, unable to get a flight back.   Even those who aren't directly impacted are silently carrying an emotional burden. I've spent much of the past week feeling helpless and longing for some way to help or be involved. I miss the city of my birth and feel the suffering of the people there.  If you're reading this and you work with anybody from Iran, be mindful of what they might be going through. Consider giving them space and understanding, extending deadlines, offering tuition relief.... or just a hug. Much love and hope. ❤️

Happy to share our teams' work on Private Database Lookups currently in production for enterprise password checks and generally applicable for other lookup features.

Private Data Lookup (PDL) is one of Meta’s latest privacy-enhancing technologies. Learn how it helps improve password security and preserves privacy for people on our family of apps. engineering.fb.com/2023/08/08/sec…

Today, we (@WhatsApp) announced our plans to deploy key transparency, as a way for users to be able to verify each other’s public keys “automatically”. Lots of details go into this, and are described in this blog post here: engineering.fb.com/2023/04/13/sec… 🧵

Proud of the work done at WA (with my team's help ;)) to be a leader in privacy-by-design at scale. First E2EE backup and now Key Transparency that lets you verify your encryption keys are authentic with little friction: engineering.fb.com/2023/04/13/sec… @_klewi @shiggschili

Woohoo! WhatsApp has released key transparency! engineering.fb.com/2023/04/13/sec…

@_klewi talked about (youtube.com/watch?v=9uIpmz…) the crypto design behind WA E2EE backup at RWC23. Lots of choices to make it secure and scalable. e.g. use of OPQAUE (github.com/facebook/opaqu…) to derive keys from PINs. 100M WA users are already using to protect their backups!!

@_klewi talks (tinyurl.com/554wmhyd) about the crypto design behind WA's E2EE Backup at RWC23! Lots of design choices to make it secure and scalable. e.g. OPAQUE (tinyurl.com/czszfb6j) to derive keys from user PINs. 100M WA users enabled it to protect their backups!

Some of our team members went on the Meta Tech podcast to talk about the work our team does at Meta. Leverage privacy enhancing technologies for data minimization at scale.

The Anonymous Credential Service is a recently open-sourced, highly available multitenant service that allows clients to authenticate in a de-identified manner. Tune in to learn from Alex and Haozhi how cryptography makes all of this possible. pca.st/episode/6a95e1…

@kostascrypto @Meta good times :)

The original cryptography team ⁦@Meta⁩ 3y ago 💪. Probably the first core crypto research group in the company’s history.

@realhamed @_aafshar_ @WhatsApp is it because these are port 80 and they can inspect application data?

What is the state of the art for internet censorship circumvention in both research and practical tools? How much better than the standard VPN services are they?

@zz7816 If you know of creative ideas please share :)

This will enable anyone to connect through servers set up by volunteers and organizations dedicated to helping people communicate freely. So when a connection to WhatsApp is blocked, people have the power to restore access. blog.whatsapp.com/connecting-to-…

Really glad to see this happening with WA!
