Our review of Hex agent
Hex offers a rich context studio where you can configure a system prompt, semantics, and endorsed tables, either created in Hex or imported via GitHub Actions. The notebook and chart UI works well once you are comfortable with it, but it remains inherently technical and best suited to data practitioners. In our benchmark, chat responses were noticeably slow — often over a minute versus roughly 20 seconds elsewhere — and there is still no dedicated AI evaluation framework.
