Below are the highlights.

New tutorials

Vercel AI Gateway RAG Knowledge Base for Customer Support

Index your help articles, PDFs, and docs, then let customers ask questions in natural language. The system embeds queries, retrieves relevant chunks from Pinecone, and generates answers with citations via Vercel AI Gateway. It includes per-query budget controls, multi-turn memory, and an automated evaluation harness to measure retrieval quality.

Multi-Agent Observability for Small Business Support

Watch all your AI agents — support bots, lead qualifiers, appointment setters — in one unified dashboard. Every agent call is instrumented with OpenTelemetry, logged, and routed to Langfuse. You can replay any past conversation, track cost and latency, and detect failure patterns.
