Rust Requires Chilkat v11.2.0+

Multimodal Input: File Data

See more AI Examples

Demonstrates sending a request that includes both text and PDF file data for the AI to analyze.

Note: At the time of writing this example, xAI, Perplexity, and DeepSeek do not have the ability to accept non-image multimodal data or URLs.

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", or "claude".
// At the time of writing this example, "deepseek", "xai", and "perplexity" do not have the ability to process non-image multimodal inputs.
// Support for additional providers will be added in future versions of Chilkat.
ai.set_provider("claude");

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

// Choose a model.
ai.set_model("claude-opus-5");

// Add both text input, and PDF file data.
let _ = ai.input_add_text("What is in this file?");

let bd = chilkat::BinData::new();
// We're passing a relative local file path here.. (relative the the app's current working directory)
if bd.load_file("qa_data/pdf/shakespeare.pdf").is_err() {
    println!("{}", bd.last_error_text());
    return;
}

// Provide the filename in the 1st argument.  The file extension is important to indicate the type of file.
let _ = ai.input_add_file_data("shakespeare.pdf", &bd, "");

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

// 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());

// -------------------------------------------------------------
// The response is in markdown format.

// Sample output:

// This PDF file contains a famous quote from William Shakespeare's "Romeo and Juliet". The quote appears twice on the page:
// 
// "These violent delights have violent ends
// And in their triumph die, like fire and powder,
// Which as they kiss consume. The sweetest honey
// Is loathsome in his own deliciousness
// And in the taste confounds the appetite.
// Therefore love moderately; long love doth so;
// Too swift arrives as tardy as too slow."
// 
// The file also includes a portrait image of William Shakespeare. This particular quote is spoken by Friar Lawrence in the play, warning about the dangers of passionate, 
// immoderate love - suggesting that love that burns too intensely tends to burn out quickly, just as fire and gunpowder consume each other when they meet.
