According to @AnthropicAI, the company has launched Bloom, an open-source tool designed to help researchers evaluate behavioral misalignment in advanced AI models. Bloom allows users to define specific behaviors and systematically measure their occurrence and severity across a range of automatically generated scenarios, streamlining the process for identifying potential risks in frontier AI systems. This release addresses a critical need for scalable and transparent evaluation methods as AI models become more complex, offering significant value for organizations focused on AI safety and regulatory compliance (Source: AnthropicAI Twitter, 2025-12-20; anthropic.com/research/bloom).
