Simple chat

For a quick question or a short exchange, you can use SendMessageAsync without managing sessions yourself. The API starts a session automatically if none exists.

Example

using Aspose.LLM;
using Aspose.LLM.Abstractions.Parameters.Presets;

var preset = new Qwen25Preset();
using var api = AsposeLLMApi.Create(preset);

string reply = await api.SendMessageAsync("What is 2 + 2?");
Console.WriteLine(reply);

Each call to SendMessageAsync without a session uses or creates the current session, so a few sequential calls form one conversation:

await api.SendMessageAsync("My name is Alice.");
string reply = await api.SendMessageAsync("What is my name?");
// reply should reflect "Alice"

When to use

• Single question/answer.
• Short back-and-forth where you do not need to save the session or share it with other code paths.

For multiple distinct conversations or explicit control, use Multi-turn chat with StartNewChatAsync and SendMessageToSessionAsync.
