Liminal AI vs. Haystack by deepset

Liminal is the way enterprises securely run AI. Liminal is a secure AI enablement platform that acts as a central hub for organizations to safely access and administer AI. Employees get unlimited access to the latest models from every leading provider through a single platform. Security and compliance teams get policy enforcement, data protection, and complete visibility into every interaction.

Haystack is deepset's open-source Python AI orchestration framework for building customizable, production-grade AI agents and workflows. Connect components like language models, vector databases, and file converters into pipelines and agents that retrieve, reason, and act on your own data; use hooks to control the agent loop: enforce a token budget before the next LLM call, incorporate human approval before a risky tool call, or use compaction to keep context small.
