We’ve opened an office in Singapore—our fifth in the Asia-Pacific region. We’ve also signed an MOU with the Government of Singapore on AI safety and responsible adoption. You can read more about our new office here: anthropic.com/news/singapore…

Using Gemini 4 makes you realize how many other models must be distilling Claude/GPT (or using a similar training pipeline). It feels quite different than other models.

I spent a decent amount of time with Gemini 4 before launch. Overall, Gemini 4 is a big jump over previous Gemini models and it is the first non-OpenAI/Anthropic model to pass the Fable/Mythos/Astra bar. It is also much more pleasant and more agentic then previous Gemini models, without the weird personality issues that you often found in Gemini 3 series models. In fact, a big advantage is that has a very different personality and sense of taste than Claude or Astra, making it a good addition to the AI world. On the usefulness side, in some areas it is at least at par with OpenAI and Anthropic (it is quite creative and a good writer), but in others it lags, including at complex multi-agent work. It has a tendency to be too certain about its conclusions and a little lazy, issues not helped by the Antigravity harness not being quite as good as the competition. Still, I expect to see rapid improvements in model abilities using Gemini 4 as a base. Here is a fun example: "create the ultimate brutalist city builder. you should have lots of controls over buildings in ways that are delightful and inuitive to people who just want to play, but are sophisticated and deep for people who know something about architecture. you should be able to play a lot with design and approach. there should be simulation modes and different ways to view or experience the city. make it stunning. i want to host this on netlify in the end" Astra Max in Codex: formwork-city.netlify.app/Fa… 5.1 Max in Code: brut-city.netlify.app/ Argon in Antigravity: rainbow-panda-689e6b.netlify…

New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

A worthwhile (and unnerving) reminder from Anthropic that we should be paying attention to AI ability thresholds, not just steady climbs In this case, the threshold is the capability needed for a self-replicating AI worm on IoT devices like off-brand TVs anthropic.com/research/self-…

Yes, and there is a case to be made that OpenAI and Anthropic will do the best job of figuring out how to optimize AI cost/intelligence with combinations of agents of different ability levels that have been specifically trained to work well together in their own harnesses.
OpenAI and Anthropic compete at the cheap end of the market, not just at the frontier.

A mathematician makes an Opus 5.5 music video in response to OpenAI’s proofs. Pretty great.
It saved some for you. (One shot!)

Not only did Astra beat Montezuma's Revenge, but so did Opus 5 But one of the criteria to resolve this AGI bet is for AI to win a discontinued prize that was sort of like a weak Turing Test. So Metaculus has decided to recreate the test to confirm the criteria is resolved. Neat!
Last month GPT-6 Astra (@chatgpt) beat Montezuma's Revenge, and a lot of people declared that our "weakly general AI" question, originally launched in 2020, resolved. But…it still hasn’t resolved. We wanted to give everyone a quick update on where things actually stand and the steps we’re currently taking (cc @swishfever @joeykrug @emollick). 🧵

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.

To help secure systems like power grids and water systems, we’re launching a new Critical Infrastructure Defense Program. We’ll bring frontier Claude models, on-site engineers, and our latest research to these operators’ security, manufacturing and technology providers.

We're deepening our commitment to scientific research and technological discovery by committing $150 million to the Genesis Mission. We'll also make Claude and our technical support available to more than 15 federal agencies. anthropic.com/news/genesis-m…

Leaving aside Anthropic's incentives for publishing this research, there is no doubt that open weights models will soon create the same security threats that closed source models have been demonstrating, except without guardrails. We are close. Probably good to plan accordingly.

Last year, we used Claude to interview 81,000 people about their hopes & worries about AI. This year, we're doing the same, but hoping to (with interviewee consent) make the transcripts public! Take part here and help build a vast social science dataset: claude.ai/anthropic-intervie…
What do you want from AI? We’re launching a new study with Anthropic Interviewer to learn more about your experiences using AI, what role you want it to play in your life and the world, and what you want from the companies building it. Last December, 81,000 people told us about their hopes and fears about AI in the largest qualitative study ever done. This time, we’re giving participants the option to make their responses public so that anyone, not just Anthropic, can learn from them. What you tell us will shape The Anthropic Institute’s research and inform the decisions we make. If many people say companies like Anthropic should be doing something differently, that will be on the record, where anyone can point to it. The study runs Sept 29 to Oct 6 and is open to Free, Pro, and Max users on Claude and Claude Code. Take part here: claude.ai/anthropic-intervie…

Making your interview public is completely optional. Our blog post covers the benefits and possible risks of doing so. Read it here: anthropic.com/research/your-…

Hey, Claude: "I asked an earlier Claude to Remove the Squid from All Quiet on the Western Front. Now you can make movies and such. I need you to show how far you have come" & I pasted in the tweet below There is some clever stuff, models have a real sense of humor at this point
👀Claude handles an insane request: “Remove the squid” “The document appears to be the full text of the novel "All Quiet on the Western Front" by Erich Maria Remarque. It doesn't contain any mention of squid that I can see.” “Figure out a way to remove the 🦑​​​​​​​​​​​​​​​​“

Claude Sonnet 5.5 is now available:
Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family. It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.

Since people liked this, and the weak point was the text to speech, I asked Opus to update with an ElevenLabs voice. This is the same video, but with much better narration.

I was reflecting on how many random contingencies went into creating the current accelerating AI moment and had Opus 5.5 put together a video, inspired by old science show Connections, to try and point out how a series of initially unrelated ideas led to the moment we are in now.
