Add gpt-4o model

[4rc0s]

gpt-4o now available and would be great to use. https://platform.openai.com/docs/models/gpt-4o

Can we tag the new commit that added the model?

Do we need to perform migration too?

https://platform.openai.com/docs/assistants/migration

has this migration implemented in the latest version?

I'm trying to use CreateThreadAndRun this function but the ThreadMessage struct has not been updated

type ThreadMessage struct {
	Role     ThreadMessageRole `json:"role"`
	Content  string            `json:"content"`
	FileIDs  []string          `json:"file_ids,omitempty"`
	Metadata map[string]any    `json:"metadata,omitempty"`
}

I think there should be Attachments field, no?
