💬 DeepSeek Chat with Reasoning Example

The ChatWithReasoningDeepSeekExample demonstrates an interactive chat session using the DeepSeek Reasoner model, focusing on eliciting thoughtful and reasoned responses from the AI.

public async Task Start()
{
    DeepSeekExample.Setup(); //We need to provide DeepSeek API key
    Console.WriteLine("(DeepSeek) ChatExample with reasoning is running!");

    await AIHub.Chat()
        .WithModel("deepseek-reasoner") // a model that supports reasoning
        .WithMessage("What chill pc game do you recommend?")
        .CompleteAsync(interactive: true);
}

🔹 How It Works

1. Set up DeepSeek API → DeepSeekExample.Setup() (API key is required)
2. Initialize a chat session → AIHub.Chat()
3. Choose a model → .WithModel("deepseek-reasoner")
4. Send a message → .WithMessage("What chill pc game do you recommend?")
5. Run the chat → .CompleteAsync(interactive: true);

This example showcases how to leverage the DeepSeek Reasoner model to engage in a conversational exchange where the AI is prompted to provide recommendations based on reasoning, making it ideal for scenarios requiring more elaborate and thought-out responses.

💡 Basic Chat without Reasoning

If you don't require the advanced reasoning capabilities, you can simply select a DeepSeek model that isn't designed for reasoning ("deepseek-chat"). The integration process remains just as straightforward.
