Jev for GEO: 8 AI-visibility jobs a decision model can run nightly

GEO measurement has a cost problem. To know whether ChatGPT, Gemini and Perplexity recommend you, you have to read thousands of their answers, and reading with a frontier model is expensive enough that most trackers sample 40 queries. Jev, TypeSafe's decision model, reads an answer and returns yes or no for about $0.0004. Here are 8 GEO jobs it fits. Ryze AI publishes this blog and does not run Jev in production yet.

What is Jev: a 45-second explainer for marketers

ChatGPT answers a question by writing a paragraph. Jev answers by picking from a list. Ask both "is this invoice fraud?" ChatGPT types out a sentence in 8 seconds. Jev gets three options, Fraud / Clean / Review, and returns a score for each in 0.1 seconds: Clean, 88%. No writing, no explaining, just the pick. That is Jev: a model that only decides, 100x faster and far cheaper. Every job on this page is a pick from a list.

What Jev looks like on AI search: demo

One recording on a sample account. Jev reads thousands of AI answers and tells you where you are cited, who is cited instead, and what to fix. The counters on screen are examples, not measurements.

GEO: check if ChatGPT, Claude and Gemini recommend you, and fix the pages that lose

Simulated run. Numbers on screen are illustrative.

Jev checks 1,450 buyer questions across three AI engines and tells you where you are cited, who is cited instead, and which pages to fix first.

  • Ask ChatGPT, Claude and Gemini about 1,450 questions your buyers ask.
  • Check every answer for two things: are you mentioned, and if not, who is.
  • Fix. For the pages that lose, Jev scores why (too thin, wrong angle, no data) and an LLM turns that into a rewrite checklist, in order.

The 8 jobs at a glance

Almost every GEO question has a bounded answer. Are we in this answer. Which competitor is. Is the mention positive. Does this page title match how the question was asked. None of that needs a model that can write, and all of it needs to run across far more queries than anyone checks today.

  8. 8Answerability scoreScore

    Question Jev answers: Score this page 0 to 100 on answering the question in its first 40 words

    What happens next: Low scores get an answer-first rewrite from the LLM

Every row has a known answer set, which is the test for whether a decision model fits. If the answer has to be written, it belongs to an LLM.

Quick answer: Jev for geo means using TypeSafe's decision model for the high-volume judgment steps in geo. 1) It answers pick-one, score and yes/no questions for about $0.0004 each. 2) It cannot write, explain or plan. 3) The top fit here is citation checks at scale, then who got cited instead. 4) Run it behind a confidence threshold, with an approval queue for the middle band. 5) Keep a frontier model for anything a person reads and a human on anything hard to undo. 6) Access is by waitlist as of September 2026.

What Jev is, in one table

Jev is a model from TypeSafe AI, the company founded by Diogo Almeida after his work on ChatGPT at OpenAI. It opened in early access on September 15, 2026. TypeSafe calls it a System One model: you send it a block of text (the state) and a set of typed questions, and it returns typed answers with a probability attached. It does not write sentences.

  1. Question types

    What TypeSafe reports
    Choice (pick one option), Score (a number in a range), Noul (a yes/no probability)
  2. Price

    What TypeSafe reports
    $0.042 per 1M input tokens. Output is free. Roughly $0.0004 per decision
  3. Latency

    What TypeSafe reports
    70 to 500 ms per call, all answers returned in one parallel pass
  4. Structured-output errors

    What TypeSafe reports
    0%, because the output is schema-constrained
  5. Accuracy on TypeSafe's 4-workflow benchmark

    What TypeSafe reports
    Jev 67.8%, Claude Opus 5 73.1%, GPT-5.6 Sol 74.1%
  6. Access

    What TypeSafe reports
    Waitlist. Early users on X report approval the same day or the next
  7. What it cannot do

    What TypeSafe reports
    Write text, code or a rationale. It gives a number and no explanation

Two caveats belong next to those numbers. The benchmarks are vendor-reported and measure agreement with frontier models, and no large independent reproduction exists yet. And TypeSafe says itself that it cannot prove the launch price is unsubsidized. Treat the price as today's price.

The 8 jobs, one by one

1. Citation checks at scale

Question: "Is our brand recommended in this answer?" Answer type: Noul. Next: Citation share per engine, per query cluster, per week.

Collecting the answers is an API and scraping job. Judging them is the expensive part today. At this price a 40-query tracker becomes a 4,000-query tracker.

2. Who got cited instead

Question: "Which of these competitors does the answer recommend?" Answer type: Choice. Next: A share-of-answer table by competitor.

Same state, second question, same call. It is the chart a GEO report is built around.

3. Sentiment of the mention

Question: "Positive, neutral or negative about us?" Answer type: Choice. Next: Negative answers are flagged with the source they drew from.

Being cited as the expensive option is a different problem from not being cited. Track it separately.

4. Title mirrors the question

Question: "Would someone asking this expect this page title?" Answer type: Noul. Next: No rows feed the retitle queue.

AI search tends to cite pages whose titles match the question wording. This check finds the pages that answer a question under a title that hides it.

5. Question coverage gaps

Question: "Do any of our pages answer this buyer question?" Answer type: Choice (URL or none). Next: The none rows are the content calendar.

Questions come from Search Console, sales calls and the engines' own follow-ups. The match decides what to write next.

6. Source triage

Question: "Is this cited source a listicle, a review site, Reddit, docs or the vendor?" Answer type: Choice. Next: An outreach list sorted by source type.

AI answers lean on a small set of third-party pages. Knowing which type dominates your category tells you where to get mentioned.

7. Reddit and forum thread triage

Question: "Does this thread recommend a competitor and leave us out?" Answer type: Noul. Next: Yes threads are worth an honest answer from the team.

Thousands of threads, a handful that matter. The yes/no finds them.

8. Answerability score

Question: "Score this page 0 to 100 on answering the question in its first 40 words" Answer type: Score. Next: Low scores get an answer-first rewrite from the LLM.

Pages that answer directly near the top are easier for an engine to quote. The score ranks the rewrite queue.

The pattern behind every use case

Every use case on this page follows one architecture. Code finds the candidates, Jev judges them, a threshold decides what happens, and a frontier model writes only what passed.

The decide-then-act loop

  1. Collect the rows with code or an API: search terms, ads, pages, AI answers. No model needed.
  2. Shortlist with rules or embeddings, so Jev sees 10 to 15 candidates per item and not the whole account.
  3. Ask Jev one bounded question per row: a Choice, a Score or a Noul. Every answer comes back with a probability.
  4. Apply a threshold. High confidence is applied automatically. The middle band goes to an approval queue. Low confidence is dropped.
  5. Write with an LLM only where text is needed: the new ad, the new title, the one-line reason a client will read.
  6. Verify the LLM's output with Jev again before it ships.

This is the same split Ryze AI already uses between changes it makes on its own and changes that wait for approval. A cheap decision model widens the first group without touching the rule for the second.

What it costs at the list price

These are arithmetic at TypeSafe's published price of $0.042 per 1M input tokens with free output. They are not measured runs, and token counts depend on how much context you put in each state.

  1. Citation checks

    Rows
    4,000 answers × 4 engines
    Approx. input tokens
    ~10M
    Cost at $0.042 per 1M
    ~$0.42
  2. Coverage gaps

    Rows
    2,000 questions
    Approx. input tokens
    ~3M
    Cost at $0.042 per 1M
    ~$0.13
  3. Thread triage

    Rows
    10,000 threads
    Approx. input tokens
    ~6M
    Cost at $0.042 per 1M
    ~$0.25

The point of the table is the order of magnitude. Jobs that cost tens of dollars per run on a frontier model, and therefore run monthly, cost cents and can run nightly.

What Jev cannot do

Jev is narrow by design, and the narrow part matters as much as the price.

  • No rationale. You get 0.91, never a sentence explaining it. Anything a client or a finance team will read still needs a frontier model to write the reason.
  • Bounded answers only. If the set of possible answers is not known up front, it is the wrong tool. Strategy, copy and diagnosis stay with an LLM.
  • Accuracy is triage-grade. 67.8% agreement on the vendor's own benchmark is fine behind a confidence threshold and wrong for auto-applying a budget change.
  • "Cannot hallucinate" means it cannot break the schema. It can still pick the wrong option. Measure it against human labels on your own data before trusting a threshold.
  • Waitlist and pricing risk. There is no general availability date, and the price may move.

Keep the frontier model for writing the comparison pages and answer-first rewrites, and for the narrative in a GEO report. Keep a human on which questions matter commercially and on any reply posted in a community.

How to start before you have access

Jev is in early access. There is no public self-serve signup yet.

1. Join the waitlist

Request access at typesafe.ai. Early users report approval the same day or within a day, but TypeSafe publishes no guarantee.

2. Label a sample first

Before you have a key, hand-label 500 rows of the job you care about. That set is how you will pick thresholds, and it works for any model.

3. Build the loop on a model you can call today

The decide-then-act loop runs on Claude Haiku 4.5 or Gemini Flash-Lite with structured outputs. It costs more per call, and the code does not change when you swap Jev in.

4. Connect the account data

The rows have to come from somewhere. Ryze AI for AI visibility gives Claude, ChatGPT, Cursor and Grok live access to the account, so the collect step is one prompt.

If you want the documentation behind this, the Ryze help center has pages on what generative engine optimization (GEO) is and how Ryze tracks your brand in ChatGPT, Gemini and Perplexity.

Frequently asked questions

What is Jev for geo?
Jev is a decision model from TypeSafe AI, released in early access on September 15, 2026. Used for geo, it answers bounded questions about rows of account or site data: pick one option, give a score, or return a yes/no probability. It costs about $0.0004 per decision at list price and cannot write text, so it handles the sorting and an LLM handles the writing.
How much does Jev cost in 2026?
TypeSafe lists Jev at $0.042 per 1 million input tokens with output tokens free, which it describes as roughly $0.0004 per decision. That is the early access launch price from September 2026. TypeSafe itself says it cannot prove the price is unsubsidized, so budget on it as today's price and re-check before you scale a job.
How accurate is Jev compared with Claude and GPT?
On TypeSafe's own four-workflow benchmark Jev scores 67.8%, against 73.1% for Claude Opus 5 and 74.1% for GPT-5.6 Sol. The benchmark measures agreement with frontier models and nobody has independently reproduced it yet. Treat Jev as triage-grade: run it behind a confidence threshold and test it against human labels on your own data first.
Can Jev query ChatGPT or Gemini for me?
No. Jev has no tools and no web access, so it cannot send prompts to ChatGPT, Gemini or Perplexity. Another system collects the AI answers through APIs or scraping. Jev then reads each answer as text and returns a decision, for example whether your brand is recommended and which competitor is named, for a fraction of a cent.
Show 9 more questions
Does Jev tell me why we were not cited?
No. Jev returns a probability with no explanation, so it can tell you that your brand is missing from an AI answer but not why. Use it to find the gaps cheaply across thousands of queries, then hand the specific answers that matter commercially to a frontier model, which can read the cited sources and explain what they have that your page lacks.
Is Jev an LLM?
TypeSafe says no. It calls Jev a System One model: a new architecture with a parallel sampler that returns every typed answer in a single pass, trained with a method named Reinforcement Learning for Calibrated Decisions. In practice the difference is simple. An LLM produces text token by token, and Jev returns a choice, a number or a probability and nothing else.
What are Choice, Score and Noul in Jev?
They are Jev's three question types. Choice picks one option from a list you provide, for example buyer, researcher or junk. Score returns a number inside a range you set, such as 0 to 100. Noul returns a yes/no probability. Every answer arrives with a calibrated confidence, which is what lets you auto-apply the confident ones and queue the rest.
How do I get access to Jev?
Jev is in early access behind a waitlist at typesafe.ai, with no general availability date as of September 2026. Early users on X report being approved the same day or within a day. You do not need to wait to start: label a sample of your data and build the same loop on Claude Haiku 4.5 or Gemini Flash-Lite, then swap the model.
Can Jev hallucinate?
Jev cannot produce malformed output, because its answers are constrained to the schema you define, and TypeSafe reports a 0% structured-output error rate. It can still be wrong. It may pick the wrong option or give a confident yes where the truth is no. That is why every workflow here uses a confidence threshold and a human approval queue for the middle band.
What can Jev not do?
Jev cannot write text, code, ad copy, page content or an explanation of its own answer. It cannot browse, call tools or read an account by itself, and it only works when the possible answers are known in advance. Strategy, diagnosis, copywriting and anything a client will read still belong to a frontier model or a person.
Does Ryze AI use Jev?
Not in production as of September 2026, because Jev is waitlist-only. Ryze AI runs the same decide-then-act loop on models that are available today: code collects the rows, a model judges them, small reversible changes are applied and larger ones wait for approval. The design lets the decision step be swapped to Jev when access opens.
What is the best way to start using Jev for geo?
Pick one high-volume job from this page, hand-label 500 rows of it, and build the loop on a model you can call today with structured outputs. Set the auto-apply threshold from your labels, not from a vendor benchmark. Connect live account data first, since a decision model is only useful when something can act on its answers.
Should a decision model replace my frontier model?
No. The two do different jobs. A decision model such as Jev takes the thousands of small, bounded calls in geo, which is where most of the token bill goes. A frontier model keeps the work that needs language: writing, rewriting, diagnosing and explaining. Most of the saving comes from routing each task to the cheapest model that can do it.
