Vancouver Style is also know as the Uniform Requirements Style. This style was created in Vancouver, British Columbia in 1978 by a group of editors of medical journals. This is a numbered style that is very similar to the AMA style.
Examples of difference reference types can be found in National Library of Medicine's Citing Medicine ebook.
A list of examples can also be found on the National Library of Medicine's webpage.
The Vancouver/Uniform Requirement format for submitting a manuscript can be found on the International Committee of Medical Journal Editors (ICMJE) website here.

AI/LLM/Generative Text Tools:
Guidelines on the use and citation of AI, large language models, and generative text tools are in flux and best practices are still emerging. Since generative AI tools and large language models are not able to be held accountable for the text they generate, they do not qualify as an author or creator. Since their output varies so substantially based on user input, the text they generate is not replicable or retrievable; therefore, it does not make sense to cite their contributions as a software either, because users would expect a particular version number to yield predictable results.
However, since the ideas or wording was not generated exclusively by the user, it is important to note the contribution of these tools. This can best be done in either the methods or acknowledgement section. Be sure to name the tool and explain when and how it was used (to generate ideas, check results, etc.). It is a good idea to also include the prompt or series of prompts you used.
These are general suggestions, but there are many opinions and context matters. Please consult your instructor or prospective publisher to check whether your proposed use of AI tools is appropriate in your given case and follow any further proposed guidance they offer.
