We are unable to train our data and model as we don't know when endpoint services will available on new openai models like O1 preview and chatgpt 4.5, can someone throw more light on these?

Hi Akshay Shah

The Azure OpenAI Service currently supports the gpt-4.5-preview model, but access to this model requires registration and is granted based on Microsoft's eligibility criteria. For the o1-preview models, support was added in the API version 2024-09-01-preview. Both models are available for standard and global standard deployment in specific regions, such as East US 2 and Sweden Central, for approved customers.

However, you can keep an eye on the Azure OpenAI Service release notes for updates on What's new in Azure OpenAI Service page will be updated accordingly with more details.

Kindly refer below link: gpt-45-preview

Thank You.

Answer 1

Hi Akshay Shah

OpenAI 4.0 supports endpoints for training custom data, allowing users to fine-tune models to their specific needs. OpenAI 4.5 is currently available as a research preview and focuses on scaling unsupervised learning and reasoning capabilities. For OpenAI 4.5, endpoint access for custom data training is not yet available. Users with generic access can utilize the model for tasks like text generation and reasoning, but fine-tuning with custom data is still limited to OpenAI 4.0. If you're using Azure OpenAI Service, you may need to request access for specific models

I asked for - Endpoint availability on openai4O1 and 4.5? - we need to train our own data, not just use the models, I have access to both the models but thats generic access, I want endpoint to train my own custom data, that is still only available in Openai4 - wanted more information on that. Hope it clarifies.
