Featured Guides

• How to classify, route, and score with Jev and AI SDK Use Jev from TypeSafe AI with AI SDK's experimental evaluate API to classify, route, score, and verify inside your application. Jev returns typed choices, scores, and boolean probabilities through AI Gateway.
• How to automatically approve tool calls in eve with Jev Use Jev to review tool calls in eve, allow routine actions, and request human approval when needed. Configure the policy and test its failure paths.
• Route form submissions with Jev and AI SDK Route form submissions to the right team with the Jev x AI SDK Form Router template. Jev routes clear cases and a fallback model decides uncertain ones.
• Moderate product reviews with Jev, TanStack AI, and AI Gateway Moderate product reviews for an e-commerce storefront with Jev from TypeSafe AI and TanStack AI's decide() function. The @tanstack/ai-vercel-gateway adapter returns typed choices, scores, and boolean probabilities through Vercel AI Gateway, so your code can publish clear reviews and hold flagged ones.
• Build a v0-style app builder with OpenAI Agents API and Vercel Sandbox Build a chat-to-app workspace with live Next.js previews, follow-up edits, and saved projects using the OpenAI Agents API preview, Vercel Sandbox, and Queues.
• Using TanStack Intent to ship and consume agent skills TanStack Intent is a CLI for shipping and consuming agent skills, markdown files that teach AI coding agents how to use a library correctly. This guide covers installing Intent, loading skills from your dependencies, and shipping skills as a maintainer.
