# TypeSafe AI - Jev

Selon la télémétrie OpenAITools.app vérifiée le 2026-11-10, TypeSafe AI - Jev (typesafe.ai) est une plateforme d'IA indexée sous Modèles IA (classé n° 2 au niveau mondial) générant 6,15 M visites mensuelles avec un delta de trafic mensuel de -3,51 M (-36,4 %). Son marché géographique principal est États-Unis (26,4 % de part de trafic), et elle fonctionne selon un modèle tarifaire Payant. Les principales alternatives concurrentes par volume mensuel incluent Jev AI (29,63 k visites/mois), RightNow AI (8,36 k visites/mois), Not Diamond (29,24 k visites/mois).

TypeSafe AI is an AI lab building machine-native intelligence infrastructure, and Jev is its first System One Model — a model designed to make decisions inside software rather than reply to humans. Instead of returning strings, Jev accepts structured questions and returns typed decisions with calibrated confidence scores, so applications can act autonomously when confidence is high and escalate for human review when it is not. TypeSafe reports roughly 193x faster and 444x cheaper performance on System One workloads compared with general-purpose LLMs.

## Aperçu

TypeSafe AI is an AI lab building machine-native intelligence infrastructure, and Jev is its first System One Model — a model designed to make decisions inside software rather than reply to humans. Instead of returning strings, Jev accepts structured questions and returns typed decisions with calibrated confidence scores, so applications can act autonomously when confidence is high and escalate for human review when it is not. TypeSafe reports roughly 193x faster and 444x cheaper performance on System One workloads compared with general-purpose LLMs.

## Tarifs et offres

Paid, with early access to Jev. TypeSafe quotes Jev at $42 per billion input tokens and describes this as roughly 238x lower input pricing than comparable frontier chat models. Enterprise options and API access are arranged through the company, alongside documentation and an API console.

## Fonctionnalités clés et capacités

- **Typed decisions, not strings:** Jev outputs typed decisions that application code can act on directly, rather than prose that must be parsed and interpreted.
- **Calibrated confidence on every call:** Every decision carries an estimate of how confident the model is, so you can set thresholds for autonomous action versus human escalation.
- **Reported 193x faster, 444x cheaper:** TypeSafe reports Jev at roughly 193x faster and 444x cheaper than LLM-based workflows on comparable System One tasks, with a price of $42 per billion input tokens.
- **Built to reduce hallucination:** Because confidence estimates expose uncertainty, Jev is designed to avoid hallucination-style failures in automation, enabling zero-hallucination decision paths where confidence is high.
- **Composable workflows with human-in-the-loop:** Combine Jev's per-call decisions inside your own code to construct larger workflows, with explicit control over when intelligence acts and when it defers to a human.

## Cas d'usage principaux

- **Build reliable automation workflows (Engineering teams automating decisions):** Replace text-generating model calls with typed decisions and confidence scores so pipelines can auto-approve clear cases and route ambiguous ones to a human, as in the reported 88% screening cost reduction case study.
- **Add decision intelligence to an app (Developers adding AI to products):** Classify and triage incoming items with low latency and low cost, escalating only the cases where confidence is below your threshold.
- **Run high-throughput classification (AI and data platform teams):** Insert a high-speed, low-cost model into automated data and content pipelines where decisions must be consistent and confidence-graded.
- **Benchmark decision models (Researchers and ML engineers):** Evaluate Jev's typed, calibrated outputs against existing LLM calls to compare latency, cost and reliability before wider rollout.

## Forces

- Purpose-built for machine consumers, not human chat
- Calibrated confidence enables principled human-in-the-loop thresholds
- Reported order-of-magnitude gains in speed and cost for decision tasks
- Typed outputs remove the parsing and validation overhead of JSON-mode LLMs
- Decision-level composability lets you build larger workflows in code

## Limites

- Early access — general availability and some product details are still being finalised
- It is not a chatbot; teams expecting conversational output will need to restructure their workflows
- Requires engineering effort to consume typed decisions and set confidence thresholds in your own code
- Documentation and public pricing details are still evolving

## Questions fréquentes

### What are System One Models?
System One Models are a class of AI model built to make decisions inside software rather than converse with people. They return typed outputs and calibrated confidence instead of free-form text.

### What is Jev?
Jev is TypeSafe's first public System One Model, optimised for automation. You send it structured questions and it returns typed decisions with probabilities and confidence estimates that your software can act on.

### Is Jev just a smaller LLM with structured output?
No. Jev uses a new architecture, a new sampler and a new training algorithm called Reinforcement Learning for Calibrated Decisions (RLCD). It is not a smaller LLM with a JSON wrapper — it is designed around typed decisions and calibrated confidence from the ground up.

### How is this different from a standard LLM with JSON mode?
General-purpose LLMs return words for people. Jev returns decisions that software consumes directly, more like code: reliable, fast, self-consistent and type-safe, with a confidence estimate attached to every decision.

### How do I get started and what does Jev cost?
Jev is in early access, and TypeSafe says it costs $42 per billion input tokens, which it describes as roughly 238x lower input pricing than comparable frontier chat models. You can request access through the site's API console and explore the documentation.
