There was a problem hiding this comment. when would we want to set There was a problem hiding this comment. yeah I haven't checked. I honestly think we need to remove this section and instead just do the translate params mappers that I started. the idea is that you get openai as input and get anthropic params as the output. This way we centralize that kind of translation to a spot vs. right now it's a pseudo translation and then have each provider decide how to grab the data from openai-like params. There was a problem hiding this comment. yes but right now this PR is doing something in between. i think we should revert this bit so we don't regress behavior and figure out the right thing to do in another PR |
