About Hal9

Hal9 supports multiple LLM backends including OpenAI and Anthropic models, and enterprise deployments can run entirely on-premises for data governance. The platform includes an agent layer that can chain multiple data operations together - answering multi-step analytical questions like comparing cohort performance over time without manual query building.
