Introducing Claude Sonnet 4.5—the best coding model in the world.
It's the strongest model for building complex agents. It's the best model at using computers. And it shows substantial gains on tests of reasoning and math.

How money works:
1. OpenAI signs $300B GPU deal with Oracle
2. Larry gains $100B (no GPUs shipped)
3. Larry invests in OpenAI’s $1T round
4. Sam uses $300B to pay Oracle
5. Oracle stock pumps again
6. Larry makes another $100B
7. Larry invests in OpenAI
Flywheel go brrr.
“OpenAI signed a $300 Billion GPU data center deal with Oracle.”
> Larry Ellison gained $101B in one day
> now the richest man alive.
> but Sam doesn't have $300B
> Larry doesn't have $300B worth of GPUs.
We’re living in a simulation.
Log probability is one of the most underutilised parts of an LLM response.
When used properly, it can improve results & provide interpretability in otherwise black box, closed source LLMs.
Unfortunately, not all major models expose it, Claude doesn’t (likely for their safety &…
Our new Threat Intelligence report details how we’ve identified and disrupted sophisticated attempts to use Claude for cybercrime.
We describe a fraudulent employment scheme from North Korea, the sale of AI-created ransomware by someone with only basic coding skills, and more.
