Save GPT-5.5

Users can build a Custom GPT that utilizes Dietly as a live food lookup tool by importing its OpenAPI schema as an Action. This setup prevents the GPT from guessing nutrition values, restricting it to a narrow retrieval task. When queried about specific foods, the GPT searches Dietly and reports the product name with per-100 g values. The process involves specific setup, grounding instructions, and essential testing before the Custom GPT is shared with others.
