- MODEL was set to 'claude-4-sonnet', a Snowflake Cortex model deprecated on 2026-04-14 and fully retired on 2026-06-15. This caused an uncaught HTTPError on every chat request. Updated to claude-sonnet-4-6, the current supported model. - Added error handling around the completion call so future model issues surface as a friendly message instead of a crash. - Constrained requires-python to >=3.12,<3.14 in pyproject.toml, since numba (a transitive dependency via snowflake-ml-python) does not yet support Python 3.14. Without this cap, uv sync fails on any environment (e.g. a fresh Codespace) that defaults to Python 3.14.

Fixes #3
Problem
The app was crashing with an uncaught
requests.exceptions.HTTPErrorwhenever a user sent a chat message. Root cause:
MODELwas set to"claude-4-sonnet", a Snowflake Cortex model that was deprecated on2026-04-14 and fully retired on 2026-06-15. Every call to
complete()therefore hit an unavailable model and Cortex returneda non-2xx response.
While reproducing this locally in a Codespace, I also hit a
dependency install failure:
uv synctried to buildnumba(atransitive dependency via
snowflake-ml-python) on Python 3.14,which
numbadoesn't support yet.pyproject.tomlonly specifiedrequires-python = ">=3.12"with no upper bound, so any environmentthat defaults to 3.14 (like a fresh Codespace) fails to install.
** Fix**
MODELto"claude-sonnet-4-6", the current supportedCortex model.
complete()call inget_response()in a try/exceptso a future model or API issue shows a friendly
st.errormessageinstead of crashing the app.
requires-pythonto">=3.12,<3.14"souv syncresolves to a Python version numba actually supports.
Testing
Verified locally in a GitHub Codespace:
uv syncfails on Python 3.14 (numba build error) andsucceeds cleanly on Python 3.12.
errors with the corrected
requires-python.account (per the README's Snowflake backend setup), which I don't
have access to, so I wasn't able to verify the live model response
end-to-end. Happy to have a maintainer confirm that part.
