LLMs and models

Nexus supports the model catalog your policy allows. The lead story is Private AI models — self-hosted or partner-hosted Private AI as the organizationally aware default.

Catalog at a glance

Category What it is
Custom LLMs (Private AI) OpenAI-compatible or Ollama endpoints you or a partner operate — the primary path for regulated / confidential workloads
Public LLMs Cloud providers (OpenAI, Anthropic, Perplexity, …) — optional, often ranked as fallback

Ranking and path

  • Drag to rank providers; the first enabled provider is the default
  • Prefer Diode connection modes (Perimeter Discover or manual bind) so the model hop stays on your private path
  • Combine with Tools and MCP so Private AI is organization-aware, not isolated

Setup: Configure an LLM.
