 * Hello
 * Thank you for the plugin. Trying every model of ChatGPT and wondering if the 
   prompt is being ignored. Alt texts come back either too long or too short regardless
   of the character limit in the prompt.
 * Does any post data or WooCommerce data get passed to ChatGPT for context?
 * Thank you

 * Hi,
 * thanks for reaching out!
 * To answer your question directly: no, the plugin does not pass any post data 
   or WooCommerce data to ChatGPT. The only things sent to OpenAI are your custom
   prompt and the image URL. The model only “sees” the picture. It has no context
   about the surrounding page, product, or article.
 * About the character limit: that instruction lives entirely inside the prompt,
   and the plugin does not truncate or post-process the response to enforce it. 
   Unfortunately, all current LLMs (including every GPT model) are quite unreliable
   at respecting exact character/word counts this is a well-known limitation of 
   how these models work, not something specific to the plugin.
 * I deliberately chose not to truncate the response programmatically: cutting the
   string at a fixed length would risk chopping a word in half and stripping the
   sentence of its meaning, which would defeat the purpose of having a descriptive,
   accessible alt text in the first place.
 * A few things you can try to get more consistent results:
    1. Be more explicit and repeat the constraint. For example: “Write an SEO-friendly
       alt text in English describing this image. The alt text MUST be between 80 and
       125 characters. Do
       not exceed 125 characters under any circumstance. Return 
       only the alt text, no quotes, no explanation.”
    2. Try GPT-4o (not Mini): in my experience it follows length constraints better
       than the Mini/o1 variants.
    3. Use a range instead of a hard limit (“between 80 and 125 characters”), models
       tend to respect ranges better than single thresholds.
    4. Avoid asking for a specific number of words or sentences in addition to characters,
       conflicting constraints make things worse.
 * That said, your point about context is a good one. I’ll consider adding the option
   to pass some surrounding context (post title, excerpt, or product data) to the
   AI in a future release, which should help the model produce more relevant and
   on-topic alt text.
   Best regards
