GPT-5 in MODEL_TO_ENCODING

[coreyc]

Does gpt-5 need to be added to the MODEL_TO_ENCODING dict? Right now the only way to use gpt-5 with tiktoken is with the trailing hyphen, but my understanding is that gpt-5 alone is a valid model identifier.

I am getting an error too
openai.NotFoundError: Error code: 404 - {'error': {'message': 'The model gpt-5- does not exist or you do not have access to it.', 'type': 'invalid_request_error', 'param': None, 'code': 'model_not_found'}}

I'm pretty sure they didn't add GPT 5 to their code in line with the other items that allow you to get tokens easily I mentioned something when 03 Mini came out and they updated this to use 03 mini... So this is a message to the developers if you read it I appreciate what you guys do but can you update this to work with GPT 5 and GPT 5 Mini... I appreciate what you guys do and I realize Open AI pretty much releases updates every day and it's hard to keep track of all that but you know I think tons of people across the world are relying on this so if that's possible I would really appreciate it.
