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

ai = Chilkat::CkAi.new()

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

# Use your provider's API key.
ai.put_ApiKey("MY_API_KEY")

# Choose a model.
ai.put_Model("gpt-5-mini")

# 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.
file_id = "file-5CnBeuFasqNcAfti3cx4Fe"
ai.InputAddImageFileId(file_id,"application/json")

ai.InputAddText("What is in this image?")

# Ask the AI for text output.
success = ai.Ask("text")
if (success == false)
    print ai.lastErrorText() + "\n";
    exit
end

# Get the text response.
sbResponse = Chilkat::CkStringBuilder.new()
ai.GetOutputTextSb(sbResponse)
print sbResponse.getAsString() + "\n";
