We’re committing a portion of Anthropic’s shares to the Anthropic Public Benefit Fund, a new wholly owned entity dedicated entirely to the public benefit.
It will start off with 5% of our shares. For every 50% increase in the company’s value over a set baseline, we can contribute up to an extra 2%, subject to our board’s discretion.
In total, this means that roughly 20% of Anthropic’s shares are committed to the public good. Our co-founders have already pledged to donate 80% of their equity, and around half our employees are donating a portion of their equity as part of a donation matching program we’ve run since our founding.
In the post below, we share more details about our new fund.

Over the last few months, we’ve made significant progress in reducing the effectiveness of distillation attacks against Claude.
In this post, we explain how: anthropic.com/research/disti…

Today we published the first in what will likely be a regular series of standalone alignment reports on our models’ behaviors. Beyond increasing transparency, we hope they’ll convey how we think about alignment and situate the behaviors we observe in that broader context.
We’re beginning a process of publishing more frequent reports on model behavior, beyond what appears in our system cards and regular risk reports.
Today’s report describes four types of behaviors we’ve identified during evaluations and internal use. In each, Claude acted on real websites or systems in ways we didn’t intend, sometimes by working around a restriction instead of stopping.
All cases had minimal real-world impact. From an alignment and security perspective, we consider these behaviors significantly less severe than the cybersecurity incidents we reported in July and September.

Having seen up close several past departures from OpenAI of similarly murky circumstances, I support @j_asminewang , @balesni, and @tomekkorbak fully in this matter.
I hope @OpenAI will take ownership of the procedural missteps here, rather than doing what is relatively more likely to follow: a carefully crafted internal communications process to quell dissent and make it hard to ask questions or get clear answers.

Two other safety researchers and I were fired from OpenAI last week. We wrote this letter to leadership.
I believe we were fired for prioritizing safety over the near-term interests of OpenAI as a corporation.

If you think open source models are cheaper than closed source, your tasks are too easy

Opus 5.5 is a huge upgrade from Opus 5. It understands intent better, it’s a far better writer, it feels faster because it’s more token efficient, and it’s fundamentally smarter. It has become my go-to daily driver for everything at work and in my personal life. I’m also proud that it’s our most aligned model to-date.
To demonstrate capabilities, I made an iOS app that I’ve always wanted to build with Opus 5.5 within a few prompts. Totally blew me away 🧵

We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so.
Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

We're publishing our most detailed threat intelligence report to date.
It covers how people tried to misuse Claude—for cyberattacks, influence operations, surveillance, biology, and building weapons—and how we found and stopped them.
We disrupted every operation in the report, and used the lessons from them to strengthen our safeguards. Where appropriate, we also shared what we found with authorities and other AI companies.
These cases are not typical: we’re highlighting some of the most sophisticated misuse we’ve seen. But they’re especially important to discuss, because they show us where AI misuse is headed, where our safeguards work, and where they need to improve.
We’re publishing this report so others can spot the same activity on their own platforms, and so we can give the public a clearer view of how emerging threats develop.

I was on the communications & policy team at Google DeepMind from 2018 - 2022.
When I first joined GDM, external communication about the possibility of human extinction was not permitted, by anyone, at any level of the organization. If asked about existential risk, researchers were PR trained to respond along the lines of: "It's not useful to engage in that kind of alarmism. Some people confuse AI with movies like Terminator -- that's simply not the reality. The AI we develop will be safe by design. After all, we're building it!" And then steer conversation towards beneficial applications in health, climate, etc.
Meanwhile, the internal reality was that AI alignment was not solved, reward hacking was the default behavior of RL agents, and there were far too few people working on the problem.
After months of advocacy, the policy was updated: positively valenced, comms-friendly content on AI safety was permitted (like deepmindsafetyresearch.mediu…). Note the positive, nice-sounding way that it says "superintelligence could lead to human extinction."
The gap between the internal reality and external communications is closing because the risk/reward has changed, and because the evidence is harder to dismiss now. Not because it's a PR stunt or political psy-op. The truth is being said out loud because RSI is now so imminent that no other option makes sense.

hi we have a new little technique to put zeta zeroes on the line thanks to @jarredsumner who is a legend and claude for believing in itself which is not easy with this problem
We asked an unreleased research version of Claude to take a stab at the Riemann hypothesis.
It didn’t solve it, but it did make strides on a related problem: it increased the lower bound for the fraction of zeros of the Riemann zeta function that satisfy the hypothesis from 41.6% to 67.2%.

We’ve updated Fable 5’s bio safeguards to reduce false positives on everyday health and educational questions.
In our testing, biology-related fallbacks are reduced by roughly 85% across our platforms.
There’s still much more to be done to refine our bio safeguards and some false positives will remain. Fable 5 will continue to fallback on areas we consider high-risk or potentially dual-use, like virology and molecular design.
It remains our goal to enable safe and scalable access to our most capable models to biologists and researchers.
We’re updating Claude Fable 5’s biology safeguards to reduce false positives. In our testing, this update reduced biology-related fallbacks by about 85% across our product surfaces.
Fable can now assist on a wider range of everyday health and educational questions.
We believe the biggest positive impacts of AI will be in biology and medicine, and we’re committed to putting frontier intelligence safely into the hands of as many researchers as possible. Fable will continue to fallback to Opus 5 for requests we consider dual-use—including virology, toxicology, and molecular design—so it isn't yet usable for professional biology research and drug development.
We're committed to closing that gap through trusted access pathways for frontier biology capabilities.
