Are There Plans to Support Python 3.14 in the Next Phoenix Release?

Amilcar P. · 2026-03-31T18:43:29.946Z

Hi everyone, I hope you're doing well. This might be a basic question (maybe too basic) , but our team is wondering whether there are any plans to support Python 3.14 in the coming months, or if there is an estimated timeline for when it will be available in the next version of Phoenix. We currently have several agents in place, along with observability already set up, and we are looking to move forward with further developments. However, we would like to use the new version of the Google ADK framework, which introduces compatibility issues with the Python versions currently supported. Any insights or updates would be greatly appreciated. Thank you in advance!

Phoenix is actively working toward Python 3.14 support. There are no known blockers for Phoenix itself, and a client update for Python 3.14 has already been merged (<https://github.com/Arize-ai/phoenix/pull/11830|PR #11830>). However, some dependencies—such as `sqlean-py`—have caused installation issues, and related OpenInference instrumentation packages are still updating their Python version requirements (<https://github.com/Arize-ai/phoenix/issues/10001|issue #10001>, <https://github.com/Arize-ai/openinference/issues/2285|issue #2285>). The Google ADK instrumentation package (`openinference-instrumentation-google-adk`) added Python 3.14 support in version 0.1.6 (<https://github.com/Arize-ai/openinference/blob/main/python/instrumentation/openinference-instrumentation-google-adk/CHANGELOG.md|CHANGELOG.md>), so you should use at least this version. In summary, Python 3.14 support is landing across Phoenix and its dependencies, but you may still encounter issues with some packages until all dependencies are fully updated. There is no official timeline, but the process is ongoing and tracked in the linked issues and changelogs. Would you like a step-by-step guide for setting up Phoenix and Google ADK with Python 3.14?

Hi Amilcar. Thanks for reaching out. It’s been a while since we last looked into this. We know that we’re blocked on Windows due to SQLite. I just did a quick test and found that Phoenix is running fine on Python 3.14, but we do have some internal CI issues that we need to fix. Once we address those, we should be able to enable 3.14 for Phoenix (except on Windows). Let us work on that and get back to you.

v13.22.0 should now work with Python 3.14 (except on Windows)
