Highlights
- TypeSafeClient and AsyncTypeSafeClient share the same typed question definitions.
- Responses group answers as response.choices, response.scores, and response.nouls.
- Advises keeping date and arithmetic logic in Python, matching the Jev 1.13 jaggedness notes.
- Suggests labeled fixtures for evaluating a router before automating it.
Questions about this entry
Short answers drawn from the linked project or page.
TypeSafeClient for scripts, AsyncTypeSafeClient so an API server never blocks its event loop. Both share the same question definitions in the official typesafe-sdk package.
Check the distribution, not just the winner: nearly-tied probabilities hide ambiguity. Log full distributions with model and question versions so you can compare versions and spot taxonomy overlap later.
Do not ask it that. Dates and arithmetic are unreliable, so compute expiry in Python and pass the fact into the state. Reserve Jev for the judgment, like whether a message asks to cancel.
Fall back to a known state. The tutorial routes timeouts and sub-0.65-confidence answers to manual_review, and treats that threshold as illustrative — calibrate it on your own traffic.
By primitive: response.choices, response.scores and response.nouls, so you read each type from its own collection rather than searching a mixed list.
With labeled fixtures: build cases with expected answers and evaluate the router against them before letting it route live traffic.
No. TypeSafeClient and AsyncTypeSafeClient share the same typed question definitions, so only the call style changes.
