Api models for a specific feature

[iisp]

Is there a possibility to get available models for specific functions. For my case I would need a list of all models that can be used for api.openai.com/v1/chat/completitons. Currently the only functionality is calling api.openai.com/v1/models which will return all possible models and I don’t know how to get information on which of these can be used for chat completitions.

I can’t post links, but the question with a title “API models endpoint with model features, pricing, context length? (yes - with this Python code)” is basically the same question but @_j has deleted(?) the credited answer or the answer is otherwise not visible to me.

This?

API models endpoint with model features, pricing, context length? (yes - with this Python code)

I’ve posted to github-q&a similar to client.models.list(), is there any way to list available/valid models at respective capability level like client.chat.models.list() or client.embeddings.models.list() ? if we pass model="text-embedding-ada-002" not suitable for chat.completion.create we get an error: NotFoundError: Error code: 404 - {'error': {'message': 'This is not a chat model and thus not supported in the v1/chat/completions endpoint. Did you mean to use v1/completions?', 'type': 'inva…

Is it @_j’s answer still in the thread , user may of removed granted solution but solution should still be in topic.

Excactly, the answer that wclayf and sashirestela credits doesn’t seem to be available. Wondering if there is a reason.

[mitchell_d00]

Because who posted the thread decides who gets solutions and looks like they unchecked it for some reason

The user ie the person who made the post can check and uncheck solution as thread evolves.

Also welcome to the forum it is a great rabbit hole

[iisp]

Not sure if we understood eachother correctly I was wondering what was the answer by @_j that these two comments are responding to as there isn’t anything and that seems to be the solution.

[iisp]

The question also still stands as this is something I would need to access via API/C# and not Python.

[mitchell_d00]

Yes I know J will probably respond to you, I was just explaining why solution may be gone. You kind of asked two questions what is the solution and why is it gone… I answered the latter…

And if he gives you the solution you can check the box and reward @_j for his work… most folks don’t check solution lol.

The list of API AI models is here:

https://platform.openai.com/docs/models

Just yesterday I posted a bit of code that will filter the list of models from the models endpoint down to those which can be used with the chat completions endpoint.

Please help. Can't get python quickstart example working - invalid_api_key?

Here’s a code snippet: either see all your chat models, or see what you did wrong with authentication import openai client=openai.Client() # automatically imports from env variables #client=openai.Client(api_key="sk-proj-badkey-hardcoded-override") starts_with = ["gpt-", "o", "ft:gpt"] blacklist = ["instruct", "moderation"] model_response = None try: model_response = client.models.list() # Makes the API call model_dict = model_response.model_dump().get('data', []) model_list = s…

You’ll likely want to “chat” with either gpt-4o-2024-11-20, or gpt-4-turbo. Alternately, submit a single question needing problem-solving ability as just a user message to o1-preview.

You can grab a list of models for each endpoint using the OpenAI OpenAPI spec.
