Zig Requires Chilkat v11.4.0+

Referencing a Pre-Uploaded Image File by file_id in an AI Request

See more AI Examples

Currently, OpenAI is the only AI provider that supports referencing a pre-uploaded image in a request for text generation. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    var success: bool = false;

    success = false;

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

    const ai = try chilkat.Ai.init();
    defer ai.deinit();

    // OpenAI is currently the only AI provider that supports referencing a pre-uploaded image by file_id
    // in a request for text generation.
    ai.setProvider("openai");

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

    // Choose a model.
    ai.setModel("gpt-5.6-luna");

    // See the following example showing how to upload a file
    // Upload an Image File to an AI Provider

    // Use the file_id of the pre-uploaded file.
    const file_id = "file-5CnBeuFasqNcAfti3cx4Fe";
    ai.inputAddImageFileId(file_id, "application/json") catch {};

    ai.inputAddText("What is in this image?") catch {};

    // Ask the AI for text output.
    ai.ask("text") catch {
        std.debug.print("{s}\n", .{try ai.getLastErrorText(alloc)});
        return;
    };

    // Get the text response.
    const sb_response = try chilkat.StringBuilder.init();
    defer sb_response.deinit();
    ai.getOutputTextSb(sb_response) catch {};
    std.debug.print("{s}\n", .{try sb_response.getAsString(alloc)});
