Image Generation: DALL-E-3

[elango-kamatchi]

How can we create image with version DALL-E-3?. Seems CreateImageAsync method, we don't have select of which version like DALL-E-2 or DALL-E-3.

Dalle3 is supported in this fork: https://github.com/lofcz/OpenAiNg

Hi lofcz, OpenAiNg supports only .NET Core >= 6.0, but my project is .NET Framework and version 4.7.2. So we cannot install OpenAiNg.

Dalle3 is supported in this fork: https://github.com/lofcz/OpenAiNg

I'm sorry to hear that, to support Dalle3 upstream, you can do the following:

1. Fork OpenAI-API-dotnet
2. Copy & paste the following changes, these are all compatible with the original database:
3. https://github.com/lofcz/OpenAiNg/commit/fb208ab37cbde43f4ddbb5e0e5cc4c152797d2cb
4. https://github.com/lofcz/OpenAiNg/commit/936dcabc2e3f07c74fa9522eda059259bf65daf9
5. https://github.com/lofcz/OpenAiNg/commit/184465a858d5ee47ebd7eebc2b0de0d144a4782f

Hope this helps.

Hello @lofcz , i have the same question this issue have. With OpenAiNg, how can you choose between Dall-E v2 and v3 (not v3 HD) or does it automatically consume the v3 ?

[lofcz]

In OpenAiNg, just provide either Dalle2 or Dalle3 as the model in the ImageGenerate request. HD needs to be toggled on manually as another argument.

Here is an example for dalle3:

OpenAiApi conn = OpenAiService.Connect(); // replace this line with your connection, something like new OpenAiApi("your_key")
ImageResult? il = await conn?.ImageGenerations.CreateImageAsync(new ImageGenerationRequest
{
    Prompt = "A lion",
    Size = ImageSize._1024,
    Model = Model.Dalle3,
    Quality = ImageQuality.Hd // ImageQuality.Standard by default
});   

(note the Quality setting)

And here for dalle2:

OpenAiApi conn = OpenAiService.Connect(); // replace this line with your connection, something like new OpenAiApi("your_key")
ImageResult? il = await conn?.ImageGenerations.CreateImageAsync(new ImageGenerationRequest
{
    Prompt = "A lion",
    Size = ImageSize._512,
    Model = Model.Dalle2
});   

Note OpenAiNg already supports the newly added Size options, exclusive for Dalle3 and also vivid / natural style. Hope this helps @VinceGsm

Many thanks @lofcz OpenAiNg is exactly what I was looking for. Have a great day !
