Strengths	+ Step-level retries and durable state without managing workers or queues + Flow control (throttling, per-tenant concurrency, rate limits) as code, useful for LLM rate limits + Runs on existing serverless or server infrastructure rather than dedicated workers + AgentKit framework targets pausable, resumable AI agent workflows	+ Native Vercel AI SDK integration + Long-running and streaming function support + Polished DX
Tradeoffs	− Execution orchestration depends on the Inngest service or self-run server, adding a platform dependency − Less low-level control than operating your own queueing or workflow cluster	− Cost can climb at sustained high throughput
