# Dynamic turns

> Change .NET model settings and tools between agent turns.

Use `DynamicModel`, `DynamicInstructions`, `Temperature`, `MaxOutputTokens`, `TopP`, and `DynamicTools` when later turns should respond to context or earlier tool results.

Tools can update application context through `RuntimeContext.SetContext` and can provide `NextTurnParams` for the immediately following request. These overrides remain with paused run state across approval continuation.

Keep application context serializable when a run may be stored through `IStateAccessor`.
