Thank you, @henriklundstrom !
First, there are a few acronyms that need to be fixed for idiomatic Go naming conventions.

Then, before continuing my review, it seems like there is a lot of duplication in the new set of structs... are there structs (potential candidates are the ones utilizing omitempty) that could possibly be shared, or is there enough distinction to warrant the current number of structs?

I'm fine if the answer is the latter - I just wanted your opinion to see if you think we could take advantage of simplifying the interface by a bit of sharing (like we do with other structs). But again, if not, no big deal... then no changes necessary.

@gmlewis I've gone through your renaming suggestions and applied them all.

I agree there are many structs being introduced and that they're somewhat repetitive, but still not actually modular, and it's not a good read... Unfortunately this is how GitHub has structured the response schema. In this case I don't see that using struct embedding or reusable structs will make it any better. Possibly, I could introduce some:

type CopilotModelBase struct {
Name string `json:"name"`
IsCustomModel bool `json:"is_custom_model"`
CustomModelTrainingDate *string `json:"custom_model_training_date,omitempty"`
}

That would cut down the size of the CopilotIDECodeCompletionsModel, CopilotIDEChatModel, CopilotDotcomChatModel, and CopilotDotcomPullRequestsModel structs, but not by much and I'm not sure it makes them any nicer to work with.

Thank you for double-checking... I appreciate it. Let's run with what you've got.

[gmlewis]

@henriklundstrom - to proceed with this PR, it looks like you need to do the following steps:

• git checkout master
• git pull upstream master (or however you set up your repo to pull from the upstream repo)
• git checkout nordnet:copilot-metrics
• git merge master
• ./script/generate.sh (see step 4 of CONTRIBUTING.md for more details)
• git push origin nordnet:copilot-metrics

This should pull #3352 into your PR which has the latest OpenAPI changes needed to support copilot-metrics.
