Jev Deep Research

Research agent where GPT plans and Jev finds evidence in parallel across document regions with Choice and Noul.

Browser extensionresearchApache-2.0

Overview

Jev Deep Research explores parallel evidence finding for research agents. GPT decides what to investigate; Jev evaluates many independent document regions concurrently; code returns the selected original passages for GPT to verify and use in the next step. One jev_find tool call fans out into independent Jev requests and gathers results before GPT continues.

GPT runs a BM25 search through Pi-Serini, which caches up to 1,000 ranked documents, then supplies a rank interval and up to six evidence questions. Code splits the documents into regions, and Jev answers a Choice (where is the evidence?) and a Noul (does this region address the question?) for each, in batches of 20, 40 or 60 documents that also cap concurrency. Code returns verbatim lines with document IDs within a 20,000-character budget, marking omissions and failures explicitly. Experiments target BrowseComp-Plus, and a paper is announced as coming soon.

What the decision model decides

TypeQuestionAnswers
ChoiceWhere in this region is the evidence for the question?—
Yes / noDoes this region address the question?—

How it works

  1. GPT searches with BM25 and picks a rank interval and evidence questions
  2. Code reads documents and splits them into regions
  3. Jev judges regions in parallel with Choice and Noul
  4. Code returns verbatim passages; GPT verifies and continues or answers

Strengths

  • Parallel evidence scanning inside one tool call
  • Returns original text with line numbers, not summaries
  • Explicit reporting of omissions and failed scans

Caveats

  • Unofficial and experimental
  • Paper not yet published
  • Requires GPT access as well as Jev

Use cases and integrations

How curated lists describe it

  • Evidence retrieval: uses Jev `Choice` to locate source lines and `Noul` to check evidence presence across document regions in parallel, then returns original passages to a GPT research agent through Pi-Serini with 20/40/60-document batch limits.

    yibie/awesome-jev
  • Unofficial experimental research agent: Jev Choice locates evidence and Noul checks its presence across document regions in parallel; Pi-Serini returns original passages for GPT to verify and continue

    AnotiaWang/awesome-decision-models
  • GPT directs the research; Jev uses Choice and Noul to locate evidence across document regions concurrently, and code returns original passages for GPT to verify and continue. The released integration pairs Pi-Serini BM25 search with Jev batches of 20, 40, or 60 documents.
