Google adds Genkit middleware for retries, fallbacks, and human‑in‑the‑loop AI apps
Google’s open‑source Genkit now offers a middleware layer that lets developers intercept generation calls to add retries, model fallbacks, and human‑in‑the‑loop safeguards. The hooks work at generate, model, and tool stages, with pre‑built components for exponential backoff, alternative model selection, and tool approval. Middleware is available in TypeScript, Go, and Dart, with Python coming soon.
