Model Registry

The Model Registry is a built-in, read-only catalog of known AI models and their providers. It helps you choose the right model for each agent role by providing capability data, tier classifications, and pricing information.

Tier system

Every model in the registry is classified into one of three tiers based on its capabilities:

Tier	Name	Description	Use case
Tier 1	Orchestrator	Top-tier reasoning models with full agent capabilities. Best tool calling, instruction following, and multi-step planning.	Supervisor agents, complex workflows, multi-agent orchestration.
Tier 2	Sub-agent	Capable models optimized for speed and cost. Reliable tool calling for focused tasks.	Specialist agents, data retrieval, single-purpose tasks.
Tier 3	Utility	Lightweight models for simple operations. May not support tool calling.	Classification, summarization, data extraction.

Admin Dashboard

The Admin Dashboard displays tier badges next to each model in the Models page:

Tier 1 models show a green badge — suitable for orchestrators.
Tier 2 models show a blue badge — suitable for sub-agents.
Tier 3 models show a gray badge — utility only.

When assigning a model to an agent, the dashboard shows a warning if the model tier does not match the agent’s role (e.g., assigning a Tier 3 model to a supervisor agent that needs tool calling).
