Our summary
An AI app often needs to choose a team or check a reply before writing more text. Christian Tzolov introduces a Spring AI Community library that gives Java applications access to Jev. It answers small questions with probabilities, named choices or ratings, rather than paragraphs.
The tutorial asks several narrow questions about the same message and gives each its own cutoff. It then shows reply checks, limited retries and tool selection. A separate question asks whether any tool fits, because picking from a list alone always produces a winner.
An uncertain answer is different from a bad one, so developers must choose what happens in either case and when retries run out. The examples include real Jev calls but scripted chat replies. Their safety cutoffs and vendor speed comparisons do not establish protection or performance for another application.
Key takeaways
- Give each narrow question its own cutoff instead of blending every concern into one rating.
- Decide explicitly what to do with an uncertain answer and with a reply that still fails after retries.
- Let tool selection return no suitable tool instead of forcing an action.
