Overview
Production-grade extensions for the Vercel AI SDK from the team behind Midday. Provides the missing production layer: a proper Agent class, persistent memory, tool caching, multi-agent handoffs with context isolation, and the AIDevtools debugging suite.
Features
- Agent Class: Wraps AI SDK calls with retry logic, context management, and structured output.
- Artifact Streaming: Stream rich artifacts (code, data, markdown) with progressive rendering.
- Cached Tools: Automatic tool result caching with configurable TTLs to avoid redundant API calls.
- Multi-Agent Handoffs: Delegate subtasks to specialized agents with full context isolation.
- Upstash Memory: Persistent conversation memory across sessions using Upstash Redis.
Use Cases
- Building a production AI pipeline beyond simple chat — multi-step reasoning, background tasks.
- Adding memory to AI conversations so context persists between user sessions.
- Debugging complex AI tool chains with the built-in AIDevtools middleware.
Technical Advantages
Agentclass is the production wrapper your entire AI pipeline needs — handles errors, retries, and timeouts.- Upstash Redis memory means conversation state survives serverless cold starts.
- Caching reduces API costs significantly in tool-heavy agents.
