Send it application state and structured questions; it returns typed answers with probabilities and confidence that your code can act on, without generating chat text. **Provider:** TypeSafe **Modality:** Utility ## Pricing ### `system_one` - Input: $0.05 / 1M tokens - Output: Free / 1M tokens Failed generations are not charged ## Technical details | Field | Value | |---|---| | Model ID | `jev-latest` | | Provider | TypeSafe | | Modality | utility | | Task type | synchronous | | Billing unit | 1K tokens | | API endpoint | `/api/v1/typesafe/system_one` | | Commercial license | Yes — included via API | | Catalog status | Operational | ## Run Jev From an Agent - [OpenClaw](https://runapi.ai/openclaw-jev.md) — Use Jev with OpenClaw agent — the RunAPI tool exposes callable actions with automatic task polling. - [Hermes Agent](https://runapi.ai/hermes-jev.md) — Use Jev with Hermes agent — describe what you need in natural language and Hermes picks the right settings. ## Get Started with Jev 1. **Create an API key** — Sign up and generate an API key from the dashboard. 2. **Pick a version** — Choose the version that best matches your quality and cost requirements. 3. **Send a request** — Submit your prompt and parameters to the model's documented endpoint. 4. **Get your result** — Poll the task or set a webhook, then download the completed output. ## About Jev on RunAPI Jev is built for automation, not chat. Through RunAPI, the Jev API uses one key and token billing alongside the rest of the catalog. **Provider:** [TypeSafe](https://runapi.ai/providers/typesafe.md) — See all → **Modality:** [Utility](https://runapi.ai/models#all-models) — Browse models → ## Why Use Jev Through RunAPI - **One auth, every provider** — A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter. - **Unified pricing & billing** — Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model. - **Schema-first SDK** — Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code. ## Jev Questions ### How is Jev different from a chat model? Chat models generate text for people. Jev returns typed decisions, probabilities, and confidence that software can branch on, sort, and route with. ### What can I use Jev for? Classification, intent routing, scoring, extraction, guardrails, and other software decisions where handwritten rules are too brittle. ### What question types does Jev support? Choice picks one option from a set you define. Score rates the state against an ordered rubric. Noul answers a yes-or-no question with a probability. ### What input does Jev accept? Text only — a string, JSON object, or array. Pre-process images, audio, or video into text before sending them as state. ### Which model identifier should I use? Use jev-latest. RunAPI maps it to the current TypeSafe Jev release. ### Which variant should I start with? Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production. ## Similar Utility Models - [OmniHuman](https://runapi.ai/models/omnihuman.md) - Bytedance - from $0.32 / second - [OpenAI Moderation](https://runapi.ai/models/openai-moderation.md) - OpenAI - Free - [Recraft](https://runapi.ai/models/recraft.md) - Recraft - from $0.01 / call - [Topaz](https://runapi.ai/models/topaz.md) - Topaz - from $0.14 / second ## Start generating with Jev - [Create free account](https://runapi.ai/login) - [Read the quickstart →](https://runapi.ai/docs/api/typesafe/system-one) ## Endpoints - `system_one` ## Category - [OmniHuman](https://runapi.ai/models/omnihuman.md) - [OpenAI Moderation](https://runapi.ai/models/openai-moderation.md) - [Recraft](https://runapi.ai/models/recraft.md) - [Topaz](https://runapi.ai/models/topaz.md) ## Provider ## Docs - [Quickstart](https://runapi.ai/docs/api/typesafe/system-one) - [API reference](https://runapi.ai/docs/api/typesafe/system-one) - [SDK README](https://github.com/runapi-ai) --- ## More from RunAPI - [Home](https://runapi.ai/.md) ### Product - [Model Catalog](https://runapi.ai/models.md) - [Pricing](https://runapi.ai/pricing.md) - [Providers](https://runapi.ai/models#all-models) ### Developers - [Documentation](https://runapi.ai/docs/guides) - [SDKs](https://runapi.ai/sdk.md) - [CLI](https://runapi.ai/cli.md) - [MCP Server](https://runapi.ai/mcp.md) ### Guides - [Claude Code vs Cursor](https://runapi.ai/claude-code-vs-cursor.md) - [Cursor API Setup](https://runapi.ai/cursor-api-setup.md) - [RunAPI vs OpenRouter](https://runapi.ai/openrouter-alternative.md) - [x402 API](https://runapi.ai/x402.md) ### Company - [Enterprise](https://runapi.ai/contact.md) - [Contact](https://runapi.ai/contact.md) ### Legal - [Terms](https://runapi.ai/terms.md) - [Privacy](https://runapi.ai/privacy.md) - [Site index for agents](https://runapi.ai/llms.txt) Contact: contact@runapi.ai ## Structured data ```json [ { "@context": "https://schema.org", "inLanguage": "en", "@type": "WebSite", "name": "RunAPI", "url": "https://runapi.ai/", "potentialAction": { "@type": "SearchAction", "target": { "@type": "EntryPoint", "urlTemplate": "https://runapi.ai/models?q={search_term_string}" }, "query-input": "required name=search_term_string" } }, { "@context": "https://schema.org", "inLanguage": "en", "@type": "Organization", "name": "RunAPI", "url": "https://runapi.ai/", "logo": { "@type": "ImageObject", "url": "https://runapi.ai/icon.svg" }, "sameAs": [ "https://github.com/runapi-ai" ] }, { "@context": "https://schema.org", "inLanguage": "en", "@type": "SoftwareApplication", "name": "Jev", "applicationCategory": "DeveloperApplication", "operatingSystem": "Cross-platform", "hasVariant": [ { "@type": "SoftwareApplication", "name": "Jev jev-latest" } ] }, { "@context": "https://schema.org", "inLanguage": "en", "@type": "BreadcrumbList", "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://runapi.ai/" }, { "@type": "ListItem", "position": 2, "name": "Models", "item": "https://runapi.ai/models" }, { "@type": "ListItem", "position": 3, "name": "Jev", "item": "https://runapi.ai/models/jev" } ] }, { "@context": "https://schema.org", "inLanguage": "en", "@type": "HowTo", "name": "From model skill to first result in four steps", "description": "Compare Jev API variants, pricing per call, and the Jev skill for app development.
