Bloom is a Python tool that automatically generates behavioral evaluation suites for LLMs, probing target models for behaviors like sycophancy, self-preservation, and political bias. It creates diverse test scenarios from a seed configuration, runs conversations with the target model, and scores the results.

Use cases

  • evaluate llm for sycophancy
  • test if a model exhibits self-preservation behavior
  • probe political bias in a chatbot
  • generate custom behavioral benchmarks for a language model
  • run automated safety evaluations on an llm api
  • measure behavior stability under emotional pressure variations

When to choose

  • you need to probe a specific LLM behavior beyond fixed benchmarks
  • you want reproducible, seed-configurable evaluation suites
  • you're doing AI safety research on model behaviors

When to avoid

  • you need a fixed, widely-cited benchmark with stable results
  • you want actively developed features - the repo is frozen and moved to Meridian Labs
  • you need non-LLM software testing
