Rust Requires Chilkat v11.2.0+

Prove Stateful Multi-Turn Conversation

See more AI Examples

This example is to prove that the 2nd request in a conversation is part of a stateful multi-turn conversation. The 2nd request asks for information provided in the 1st request. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let ai = chilkat::Ai::new();

// The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
// Support for additional providers will be added in future versions of Chilkat.
ai.set_provider("google");

// Use your provider's API key.
ai.set_api_key("MY_API_KEY");

// Choose a model.
ai.set_model("gemini-3.6-flash");

// Create a new conversation to be maintained locally in memory.
// If the conversation is the first to be created, it is also automatically selected.
let system_msg = "You are a helpful assistant".to_string();
let developer_msg = String::new();
let conversation_name = "test_conversation".to_string();
let _ = ai.new_convo(&conversation_name, &system_msg, &developer_msg);

// -------------------------------------------------------------------------------------------
// Our first request will establish a secret that we'll ask for in the 2nd request.
// Add a text input.
let _ = ai.input_add_text("Please remember this: The word I'll ask for later is BlubberFish.  What's the word?");

// Ask the AI for text output.
if ai.ask("text").is_err() {
    println!("{}", ai.last_error_text());
    return;
}

// Note: The inputs accumulated through one or more calls to Input* methods are cleared when the Ask method returns with success.

// Get the text response.
let sb_response = chilkat::StringBuilder::new();
let _ = ai.get_output_text_sb(&sb_response);
println!("{}", sb_response.get_as_string().unwrap_or_default());
println!("----");

// Sample output:

// The word is **BlubberFish**.

// -------------------------------------------------------------------------------------------
// Let's ask for the word. If this is a stateful conversation, the AI should respond correctly.
let _ = ai.input_add_text("OK, I'm going to ask you again, what's the word?");
if ai.ask("text").is_err() {
    println!("{}", ai.last_error_text());
    return;
}

// Get the text response.
sb_response.clear();
let _ = ai.get_output_text_sb(&sb_response);
println!("{}", sb_response.get_as_string().unwrap_or_default());

// Sample output:

// The word is **BlubberFish**.

// -------------------------------------------------------------------------------------------
// Look at the conversation so far...
// 
let json = chilkat::JsonObject::new();
let _ = ai.export_convo(&conversation_name, &json);
json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());

// Note: The conversation transcript format exported and imported by Chilkat is always the OpenAI format,
// regardless of the AI provider.  (Chilkat translates the format from OpenAI to whatever is needed by the actual AI provider being used.)

// Could you please remind me or provide the clue again? I'm ready to help you figure it out!
