Our summary

RubyLLM helps Ruby programs contact several AI services through a common interface. This add-on connects Jev for focused questions only. A developer defines yes-or-no questions, fixed choices, or rating levels and supplies the information those questions should examine.

The guide explains installation, connection settings, and reading the answers. The response includes the selected values and estimates of how strongly alternatives were favoured. Known connection and request problems are reported in forms the RubyLLM application already knows how to handle.

A common connection does not give every model the same abilities. Jev does not write chat replies or stream text, and this add-on rejects those requests. Applications still need private-key protection, failure handling, and their own rules for acting on uncertain answers.

Key takeaways

Define the allowed questions before sending information.
Read the estimates as well as the selected answer.
Do not expect a shared interface to give Jev writing abilities.
