Jev Playground Vercel released Jev Playground, a browser-based tool from typesafe-ai/jev that runs on the Vercel AI Gateway and answers text, JSON, questions, Boolean, Choice, and Score prompts in a single parallel pass using a 32K-token context. The playground requires a Vercel AI Gateway API key, supports an auto-accept threshold of 90%, and reports round trip, input tokens, output tokens, and estimated cost per run, with zero data retention listed as unset.
