Anthropic· Updated
Anthropic released Bloom, an open-source tool that automatically generates behavioral misalignment evaluations for AI models. Specify a behavior like deception or sycophancy, and Bloom creates scenarios to quantify how often it appears and how severe each instance is.
Eval creation is one of the bottlenecks in AI safety research. Hand-crafting test cases is slow and misses edge cases. Bloom automates scenario generation, letting researchers focus on defining what behaviors matter rather than manually writing thousands of test prompts. It's infrastructure that makes safety research more systematic.
Bloom turns behavioral hypotheses into quantified measurements - from defining the target behavior to automated scenario generation and severity scoring.
We’re releasing Bloom, an open-source tool for generating behavioral misalignment evals for frontier AI models. Bloom lets researchers specify a behavior and then quantify its frequency and severity across automatically generated scenarios. Learn more: https://t.co/TwKstpLSy3
