"Invest in companies that would be happy to see a 100x improvement in foundation models" -- paraphrasing Sam Altman

Introducing Cowork: Claude Code for the rest of your work. Cowork lets you complete non-technical tasks much like how developers use Claude Code.





@uncle_deluge The most ironic outcome is the most likely


We’ve formed a partnership with NVIDIA and Microsoft. Claude is now on Azure—making ours the only frontier models available on all three major cloud services. NVIDIA and Microsoft will invest up to $10bn and $5bn respectively in Anthropic. anthropic.com/news/microsoft…


We made ChatGPT pretty restrictive to make sure we were being careful with mental health issues. We realize this made it less useful/enjoyable to many users who had no mental health problems, but given the seriousness of the issue we wanted to get this right. Now that we have been able to mitigate the serious mental health issues and have new tools, we are going to be able to safely relax the restrictions in most cases. In a few weeks, we plan to put out a new version of ChatGPT that allows people to have a personality that behaves more like what people liked about 4o (we hope it will be better!). If you want your ChatGPT to respond in a very human-like way, or use a ton of emoji, or act like a friend, ChatGPT should do it (but only if you want it, not because we are usage-maxxing). In December, as we roll out age-gating more fully and as part of our “treat adult users like adults” principle, we will allow even more, like erotica for verified adults.
