Vectorize Configuration

Create Index

npx wrangler vectorize create my-index --dimensions=768 --metric=cosine

⚠️ Dimensions and metric are immutable - cannot change after creation.

Worker Binding

// wrangler.jsonc
{
  "vectorize": [
    { "binding": "VECTORIZE", "index_name": "my-index" }
  ]
}

interface Env {
  VECTORIZE: Vectorize;
}

wrangler vectorize create-metadata-index my-index --property-name=price --type=number
