Are AI Studio's 1.0-pro-vision-001 and API's gemini-1.0-pro-vision-latest exactly the same model ?

[Yuma]

With Vertex AI Studio, I get the response as expected, but via the API, the quality of the response may be lower, or it may give a wrong response different from AI Studio. I think I am using the same model (1.0-pro-vision-001) and parameters for the request, but is it different internally?

The image is an example in Japanese, but when I asked Vertex AI Studio to extract questions and answers for the same image, it extracted everything correctly, but when I used the API (postman), there are some incorrect parts extracted.
In postman, we use pro-vision-latest, which we recognize to mean the same as vertexAI's 001 model.

Why does the quality of the answers change?
Is it the same 001 model but different internally?
Thank  you in advance.
