Deduplicate list of models

[nbonamy]

When calling models.list, the list returns models that look similar: all fields are the same except the name. But the name is so different that it makes one wonder if they are the same models or not.

For instance for Gemini 2.5 Flash Preview 05-20:

models/gemini-2.5-flash-preview-05-20
description:"Preview release (April 17th, 2025) of Gemini 2.5 Flash"
displayName: "Gemini 2.5 Flash Preview 05-20"
inputTokenLimit:1048576,
maxTemperature: 2,
name: "models/gemini-2.5-flash-preview-05-20",
outputTokenLimit: 65536,
supportedGenerationMethods: [...],
temperature:1,
thinking:true,
topk: 64,
topP: 0.95,
version:"2.5-preview-05-20"

models/gemini-2.0-flash-thinking-exp-01-21
description: "Preview release (April 17th, 2025) of Gemini 2.5 Flash"
displayName: "Gemini 2.5 Flash Preview 05-20"
inputTokenLimit:1048576,
maxTemperature: 2,
name: "models/gemini-2.0-flash-thinking-exp-01-21",
outputTokenLimit: 65536,
supportedGenerationMethods: [...],
temperature:1,
thinking:true,
topk: 64,
topP: 0.95,
version: "2.5-preview-05-20"

Those models are probably the same but the fact that one name says thinking and the other one does not is really confusing.

On which basis can we assume these models are the same? I am thinking the version field should be the right one. Correct?

Thanks!

Hi @nbonamy,

Thank you for bringing this issue to our attention. I've verified the duplicate displayname entries for the models Gemini 1.0 Pro Vision and Gemini 2.5 Flash Preview 05-20. I will escalate this to the team and provide an update as soon as I have more information.
