Key differences from Vercel AI Gateway

1

LLMWise is provider-agnostic and works with any framework, while Vercel AI Gateway is designed primarily for the Vercel ecosystem and Next.js applications.

2

LLMWise provides five orchestration modes including compare, blend, and judge that let you synthesize outputs from multiple models in a single API call, which Vercel AI Gateway does not support.

3

Policy-based routing in LLMWise enforces cost, latency, and reliability constraints automatically, whereas Vercel AI Gateway relies on the developer to implement routing logic in application code.

4

The replay lab and optimization snapshots give you data-driven routing decisions with drift alerts, replacing the manual experimentation cycle typical with Vercel AI Gateway setups.

How to migrate from Vercel AI Gateway

  1. 1Identify which Vercel AI SDK providers and models you currently use, and note any custom middleware or streaming configurations in your Next.js application.
  2. 2Sign up for LLMWise and create your API key. Map your current model strings to LLMWise model IDs (they differ), using the dashboard model picker or docs as the source of truth.
  3. 3Replace your Vercel AI Gateway calls with LLMWise endpoints (SDK or direct HTTP). If you use the Vercel AI SDK UI, add a thin Next.js route handler that calls LLMWise and forwards the SSE stream to the client.
  4. 4Enable optimization policies for your production routes and test with replay lab. Set up mesh failover to add reliability that Vercel AI Gateway does not provide natively.
Example API request
POST /api/v1/chat
{
  "model": "auto",
  "optimization_goal": "cost",
  "messages": [{"role": "user", "content": "..." }],
  "stream": true

Common questions

Will this work with existing Vercel AI app code?
Yes. You can keep the Vercel AI SDK UX, but the integration is not a base-URL swap. Call LLMWise from your server (SDK or HTTP) and stream the SSE output to your client.
Do I still get provider flexibility?
Yes. You can route across multiple providers and enforce model-level policy constraints.
How much does LLMWise cost compared to Vercel AI Gateway?
Vercel AI Gateway pricing is bundled with Vercel's platform tiers. LLMWise uses standalone credit-based pricing with reserve-and-settlement (Chat starts at 1 reserve credit, Compare 2, Blend 4, Judge 5) plus BYOK options for direct provider billing. Teams not on Vercel's platform often save by using LLMWise directly.
Can I use Vercel AI Gateway and LLMWise together?
Yes. You can keep your Next.js frontend and Vercel AI SDK UI while routing requests through LLMWise. In practice, most teams stop using Vercel AI Gateway once LLMWise is in the request path, because LLMWise already provides routing, failover, and usage settlement.
What's the fastest way to switch from Vercel AI Gateway?
Add a server route in your Next.js app that calls LLMWise with your API key and forwards the SSE stream. Start with one endpoint, verify streaming + errors, then migrate the rest and turn on optimization policies and mesh failover.
