Would be great to extend this to include a Title, and Keywords

progressScope:setCaption("Requesting alt text, title, and keywords from OpenAI...")

local content = response.choices[1].message.content
local title = content.title:match("^%s*(.-)%s*$")
local altText = content.alt_text:match("^%s*(.-)%s*$")
local keywords = content.keywords:match("^%s*(.-)%s*$")

    photo.catalog:withWriteAccessDo("Set Metadata", function()
        photo:setRawMetadata('title', title)
        photo:setRawMetadata('caption', altText)
        photo:setRawMetadata('keywords', keywords)
    end)
    LrDialogs.showBezel("Title, alt text, and keywords generated and saved.")
    return true

Would some thing like the above work?

That might work, but the ChatGPT prompt and API call would need to be updated to ask for those things and return structured data (using JSON mode), and then the response would have to be parsed accordingly to pull the new fields.

So something like
messages = {
{
role = "system",
content = config.SYSTEM_PROMPT
},
{
role = "user",
content = "Please provide a title, alt text, and keywords for the following image in JSON format with keys 'title', 'alt_text', and 'keywords'."
},
{
role = "user",
content = {
type = "image_url",
image_url = {
url = "data:image/jpeg;base64," .. imageBase64
}
}
}
}

and
if response and response.choices and response.choices[1] and response.choices[1].message and response.choices[1].message.content then
local metadata = json.decode(response.choices[1].message.content)
local title = metadata.title:match("^%s*(.-)%s*$")
local altText = metadata.alt_text:match("^%s*(.-)%s*$")
local keywords = metadata.keywords:match("^%s*(.-)%s*$")

    photo.catalog:withWriteAccessDo("Set Metadata", function()
        photo:setRawMetadata('title', title)
        photo:setRawMetadata('caption', altText)
        photo:setRawMetadata('keywords', keywords)
    end)
    LrDialogs.showBezel("Title, alt text, and keywords generated and saved.")
    return true

I don't know the lightroom metadata tags.
