Chat Client Reasoning Streaming

This example assumes using Together; is in scope and apiKey contains your Together API key.

using var client = new TogetherClient(apiKey);
Meai.IChatClient chatClient = client;

var updates = chatClient.GetStreamingResponseAsync(
    [new Meai.ChatMessage(Meai.ChatRole.User, "What is 25 * 37? Think step by step.")],
    new Meai.ChatOptions
    {
        ModelId = "deepseek-ai/DeepSeek-R1",
    });

var reasoningDeltas = new List<string>();
var textDeltas = new List<string>();

await foreach (var update in updates)
{
    foreach (var content in update.Contents)
    {
        if (content is Meai.TextReasoningContent rc && !string.IsNullOrEmpty(rc.Text))
        {
            reasoningDeltas.Add(rc.Text);
        }
        else if (content is Meai.TextContent tc && !string.IsNullOrEmpty(tc.Text))
        {
            textDeltas.Add(tc.Text);
        }
    }
}
