Usage

using OpenAI;

    Celsius,
    Fahrenheit,

    public double Temperature { get; set; }
    public Unit Unit { get; set; }
    public string Description { get; set; } = string.Empty;
}

Constants

This repository contains the library with constants for all OpenAI constants(models/prices/context length and other).

using OpenAI.Constants;

string id = EmbeddingModels.Version3Small; // implicit conversion to string
double price = EmbeddingModels.Version3Small.GetPriceInUsd(tokens: 500); // 0.00001
EmbeddingModels.Version3Small.MaxInputTokens // 8191
EmbeddingModels.Version3Small.PricePerTokenInUsd // 0.00000002
