let-jev-speak

Experiment that makes Jev produce prose by asking one choice question per word over a routed domain vocabulary.

LibraryresearchMIT

Overview

let-jev-speak coaxes free-text answers out of TypeSafe's classification endpoint. Since /v1/systemone only returns choices, scores and probabilities, the library asks one choice question per word over a vocabulary and feeds the answer so far back in as the prefix. The model first routes the question to one of 28 domain vocabulary packs with a single choice call, which scored 60 of 60 on a labelled set and roughly doubles answer quality versus a generic vocabulary, then decodes word by word. A query like 'Why is the sky blue?' takes about 14 calls.

The author is explicit that this is not a good idea: a single well-posed choice question answers the same question better, in one call, with calibrated confidence. It is a working demonstration of what the endpoint can be pushed into and a map of where it stops, documented in a findings file. It has no dependencies, runs on Node 18+, and has a demo video and a Telegram bot.

What the decision model decides

TypeQuestionAnswers
ChoiceWhich domain vocabulary pack fits this question?—
ChoiceWhich word comes next in the answer?—

How it works

  1. Route the question to a domain vocabulary with one choice call
  2. Ask a few prior questions
  3. Decode the answer one word at a time with choice calls
  4. Feed the growing answer back as the prefix
  5. Return text with routing and usage stats

Strengths

  • Shows the limits of a decision-only API
  • Domain routing measurably improves output
  • Zero dependencies

Caveats

  • Author says it is not a good idea for real use
  • Many calls per answer
  • Output quality is limited

Getting started

git clone git@github.com:suidouble/let-jev-speak.git, then new LetJevSpeak(TYPESAFE_API_KEY).answer('Why do cats purr?').

How curated lists describe it

  • TypeSafe's \`/v1/systemone\` endpoint classifies text — it returns a \`choice\`, a \`score\`, or a probability. It does not generate prose. This library makes it generate prose anyway: every word of the answer is a separate \`choice\` question over a vocabulary, and the loop feeds its own output back in as the prefix.

Frequently asked questions

Can Jev generate text?

Not natively; this library picks one word at a time with choice questions.

Should I use this in production?

The author says no; a single choice question is better.

How many calls does an answer take?

About 14 in the README's example.
