If you love creating your own Custom GPTs for specific tasks with your own knowledge sets, GPT-5 has now broken this feature.
- Uploading files only produces errors.
- Using the “Create” feature to write or update informational prompts either throws errors or acts like a normal chat, it never seems to update your custom GPT’s instructions.
Very disappointed there’s no option to continue with GPT-4 models while they fix the problems.
This is a perfect example of how NOT to launch AI projects to clients.
AI is powerful for industrial applications. But it’s not magic.
It takes experience and people skills to get it right the first time, every time.
Choose your partners wisely, and your AI projects will succeed.
