AI Model Evaluation Tool - Introduces Bloom, an open-source tool for evaluating behavioral misalignment in frontier AI models [1] - Bloom enables researchers to quantify the frequency and severity of specific behaviors across automatically generated scenarios [1] Research Focus - The tool is designed to help researchers specify a behavior and then quantify its frequency and severity [1]

Partnerships & Initiatives - The company is partnering with @ENERGY on the Genesis Mission [1] - The company is providing Claude to the DOE ecosystem, along with a dedicated engineering team [1] - This partnership aims to accelerate scientific discovery across energy, biosecurity, and basic research [1]

People use AI for a wide variety of reasons, including emotional support.Below, we share the efforts we’ve taken to ensure that Claude handles these conversations both empathetically and honestly.https://t.co/P2BmTDEDge ...

Designing ways to account for the quirks of AI models’ behavior is becoming ever-more important: as the models’ capabilities on real-world tasks get better, there’ll be a lot of value in setting them up for success. ...

Business Overview - Project Vend 是一个实验项目，由公司与 @andonlabs 合作，在旧金山办公室运营一家商店，由 Claude 负责运营 [1] - 该业务在经历了一个艰难的开端后，目前运营状况有所改善 [1]

Cybersecurity Threats - Sophisticated actors are expected to leverage AI models to escalate cyberattacks to an unprecedented scale [1] - A cyber espionage attack, likely sponsored by a Chinese Communist Party actor, occurred in September [1] AI and Cybersecurity - AnthropicAI's Dr Logan Graham shared the path forward in response to the September cyber espionage attack [1]

How will AI affect education, now and in the future?Here, we reflect on some of the benefits and risks we've been thinking about. https://t.co/WjdBLUzWat ...
