ASP.NET MVC LLM Kit Overview
Updated on Aug 11, 2026
The Telerik UI for ASP.NET MVC LLM Kit is a set of purpose-built components for bringing AI agent activity into your application.
The kit provides ready-made building blocks for showing reasoning traces, multi-step thought chains, tool invocations, inline citations, and conversation checkpoints alongside any chat or agentic interface.
Key Features
- Reasoning—Shows a model's thinking trace in one collapsible block, with support for streaming content token by token.
- Chain of Thought—Collects an ordered series of thought steps beneath one collapsible header, with support for custom row templates.
- Tool Call—Shows an individual tool or function invocation, including parameters, approval flow, results, and error states.
- Checkpoint—Places a decorative separator between conversation turns with a Start Over or Redo action.
- Citation—Adds an inline reference chip that opens a paginated popover containing complete source details.
