# npm install ai && Cry Later

Problem: Roast the AI-agent idea implied by my GitHub repo "vercel/ai". What it does: The AI Toolkit for TypeScript. From the creators of Next.js, the AI SDK is a free open-source library for building AI-powe…

## verdict

tier: ALREADY EXISTS, YOU'RE LATE
difficulty: 8/10
savage_line: You asked me to roast a library that roasts every competitor just by existing. Respect.

## ship_it_anyway

differentiator: Build the eval + observability layer Vercel AI SDK deliberately left out — LLM-as-judge scoring, regression testing, and prompt versioning baked into the same `npm install` ergonomics.
riskiest_assumption: That TypeScript developers will pay for evals when LangSmith and Braintrust already exist. Test willingness to pay before writing a line.
honest_cost: 6 months, $80k in runway minimum. Do NOT build this if you're a solo dev without an existing Next.js audience — Vercel will ship evals themselves by the time you launch.
