Next.js app cookbook

This cookbook includes quickstart, multi-turn chat, and personify pages. Quickstart and chat use the OpenAI-compatible provider base URL; personify calls the native JSON endpoint.

Key notes

Uses Vercel AI SDK provider setup with ThinkFeel’s OpenAI-compatible base URL.
ThinkFeel completions are non-stream. The UI expects complete reply responses.
ThinkFeel personify uses the native /api/v1/personify JSON endpoint.
Tool-calling and some OpenAI parameters remain unsupported.
Error responses are grouped as validation, config, or provider errors.
If overriding THINKFEEL_BASE_URL for this OpenAI-compatible cookbook, include /api/v1.
For ThinkFeel SDK or CLI setup, use the origin only.
Legacy CURVE_* environment names remain fallback-only.
New setup should use THINKFEEL_* names.
