Questions About Arize AX Migration Roadmap and Feature Parity with Phoenix Cloud
Hi. I'm evaluating Arize as an alternative to Langsmith, which we've been using so far, From what i can tell it looks like Arize is in the middle of migrating from Phoenix Cloud to AX as the primary product offering, with APIs changing from v1 to v2, auth flows redirecting to AX, but silently still supporting Phoenix Cloud. But it also looks like AX doesn't have full feature parity with Phoenix Cloud yet either. Frankly the experience right now is confusing. Is there a blog post or documentation explaining the roadmap of when AX will be on par? Gaps that I have noticed so far poking at it:
AX doesn't have a python async client (have to use async to_thread)
With the AX python sdk i can't fetch a prompt from prompt hub by name, only by id. To get it by name, i have to use the list endpoint, map name to id and then get the prompt object by id
AX does not have a model cost config for gpt-5.4 (phoenix cloud does)
