hey @elentaure. we are working on this. The plan is to make universal finetuning api, following api signature with what openai does, with minimal changes to other providers.
Here is how we will be implementing this
- The file should be openai finetuning format and on the fly we convert it to provider specific finetuning format.
- The finetuning jobs api will closely follow openai format and will support the following providers at the start (openai, azure, bedrock). with future support for fireworks
We would love if you can create a PR for Vertex, but I would suggest you to wait for some time, till we make the basic structure GA.
