Side by side
Vercel AI SDK
TypeScript toolkit for streaming AI interfaces and provider-agnostic model calls.
- Strongest at
- excellent streaming UX primitives and clean provider switching
- Trade-off
- TypeScript-centric, Python teams are better served elsewhere
- Vendor
- Vercel
LangGraph
Graph-based orchestration for agent workflows with explicit state and checkpoints.
- Strongest at
- explicit control flow and resumable state, which is what complex agents actually need
- Trade-off
- meaningful overhead for simple single-step tasks that need no orchestration at all
- Vendor
- Open source
How we would actually choose
Choose Vercel AI SDK when excellent streaming UX primitives and clean provider switching is the property your workload depends on, and accept that TypeScript-centric, Python teams are better served elsewhere.
Choose LangGraph when explicit control flow and resumable state, which is what complex agents actually need matters more, accepting that meaningful overhead for simple single-step tasks that need no orchestration at all.
In practice most production systems we build use both, routed by task. Standardising on one option for tidiness usually costs more than the tidiness is worth.
Orqent Labs holds no reseller commission on Vercel or LangGraph. We benchmark both on your workload and report what the numbers say.
Questions
Vercel AI SDK or LangGraph, which should we use?
Pick Vercel AI SDK when excellent streaming UX primitives and clean provider switching is what your workload depends on. Pick LangGraph when explicit control flow and resumable state, which is what complex agents actually need matters more. Most production systems we build end up using both for different tasks rather than standardising on one.
What is the catch with Vercel AI SDK?
TypeScript-centric, Python teams are better served elsewhere.
What is the catch with LangGraph?
Meaningful overhead for simple single-step tasks that need no orchestration at all.
Do you have a preference?
Not a fixed one, and we hold no reseller commission on either. We benchmark both on your actual workload and recommend from the result, which occasionally means recommending neither.
