Arrays for model names

Describe the feature or improvement you're requesting

I have a need for model names defined as iterables, in particular for enforcing typesafety in various places.

Take Sequelize enums for example:

DataTypes.ENUM({
  values: ['value', 'another value']
})

or programmatically generating GraphQL enums:

const RGBType = new GraphQLEnumType({
  name: 'RGB',
  values: {
    RED: { value: 0 },
    GREEN: { value: 1 },
    BLUE: { value: 2 }
  }
});

or Zod enums:

const VALUES = ["Salmon", "Tuna", "Trout"] as const;
const FishEnum = z.enum(VALUES);

As it stands with the union type exported from OpenAI, we'd have to manually create these arrays and maintain them on our side.

It would be great to have something like this instead which would give us the best of both worlds:

export const ChatModelArray = [
  'gpt-4o',
  'gpt-4o-2024-05-13',
  'gpt-4-turbo',
  'gpt-4-turbo-2024-04-09',
  'gpt-4-0125-preview',
  'gpt-4-turbo-preview',
  'gpt-4-1106-preview',
  'gpt-4-vision-preview',
  'gpt-4',
  'gpt-4-0314',
  'gpt-4-0613',
  'gpt-4-32k',
  'gpt-4-32k-0314',
  'gpt-4-32k-0613',
  'gpt-3.5-turbo',
  'gpt-3.5-turbo-16k',
  'gpt-3.5-turbo-0301',
  'gpt-3.5-turbo-0613',
  'gpt-3.5-turbo-1106',
  'gpt-3.5-turbo-0125',
  'gpt-3.5-turbo-16k-0613',
];

export type ChatModel = (typeof ChatModelArray)[number];
