Introducing the next generation: Claude Opus 4 and Claude Sonnet 4. Claude Opus 4 is our most powerful model yet, and the world’s best coding model. Claude Sonnet 4 is a significant upgrade from its predecessor, delivering superior coding and reasoning.
Glad you're making this commitment. I do think it's unfortunate that you only made it after public pressure and the Attorneys General getting involved. Had you done this back in December, it would have looked like principle, not like you got dragged kicking and screaming.…
4 facts about our structure: -OpenAI will continue to be controlled by the current nonprofit -Our existing for-profit will become a Public Benefit Corporation -Nonprofit will control & be a significant owner of the PBC -Nonprofit & PBC will continue to have the same mission

Anthropic has raised $3.5 billion at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners. This will advance our development of AI systems, deepen our understanding of how they work, and fuel our international expansion. Read more: anthropic.com/news/anthropic…
Excited for our new launch! We've been working hard on getting this out. Looking forward to hearing everyone's feedback on the model!
Introducing Claude 3.7 Sonnet: our most intelligent model to date. It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking. One model, two ways to think. We’re also releasing an agentic coding tool: Claude Code.
I recently joined @AnthropicAI! Very excited to work with @OrowaSikder and the Knowledge team on improving Claude's tool use abilities. And looking forward to working at a place with a high-integrity leadership team that values being honest and transparent with their employees.
Top researchers Yoshua Bengio, @geoffreyhinton, Lawrence @Lessig & Stuart Russell are calling for lawmakers to pass SB 1047. “As of now, there are fewer regulations on AI systems that could pose catastrophic risks than on sandwich shops or hairdressers.” time.com/7008947/califo…
Safe(-ish)!
We are building an early warning system for LLMs being capable of assisting in biological threat creation. Current models turn out to be, at most, mildly useful for this kind of misuse, and we will continue evolving our evaluation blueprint for the future. openai.com/research/build…
