1. ### [Return up to 50 query results with values or metadata](https://developers.cloudflare.com/changelog/post/2026-03-16-topk-limit-increased-to-50/)  
[ Vectorize ](https://developers.cloudflare.com/vectorize/)  
You can now set `topK` up to `50` when a Vectorize query returns values or full metadata. This raises the previous limit of `20` for queries that use `returnValues: true` or `returnMetadata: "all"`.  
Use the higher limit when you need more matches in a single query response without dropping values or metadata. Refer to the [Vectorize API reference](https://developers.cloudflare.com/vectorize/reference/client-api/) for query options and current `topK` limits.

1. ### [Vectorize indexes now support up to 10 million vectors](https://developers.cloudflare.com/changelog/post/2026-01-23-increased-index-capacity/)  
[ Vectorize ](https://developers.cloudflare.com/vectorize/)  
You can now store up to 10 million vectors in a single Vectorize index, doubling the previous limit of 5 million vectors. This enables larger-scale semantic search, recommendation systems, and retrieval-augmented generation (RAG) applications without splitting data across multiple indexes.  
Vectorize continues to support indexes with up to 1,536 dimensions per vector at 32-bit precision. Refer to the [Vectorize limits documentation](https://developers.cloudflare.com/vectorize/platform/limits/) for complete details.

1. ### [List all vectors in a Vectorize index with the new list-vectors operation](https://developers.cloudflare.com/changelog/post/2025-08-26-vectorize-list-vectors/)  
[ Vectorize ](https://developers.cloudflare.com/vectorize/)  
You can now list all vector identifiers in a Vectorize index using the new `list-vectors` operation. This enables bulk operations, auditing, and data migration workflows through paginated requests that maintain snapshot consistency.  
The operation is available via Wrangler CLI and REST API. Refer to the [list-vectors best practices guide](https://developers.cloudflare.com/vectorize/best-practices/list-vectors/) for detailed usage guidance.

1. ### [Create fully-managed RAG pipelines for your AI applications with AutoRAG](https://developers.cloudflare.com/changelog/post/2025-04-07-autorag-open-beta/)  
[ AI Search ](https://developers.cloudflare.com/ai-search/)[ Vectorize ](https://developers.cloudflare.com/vectorize/)  
[AutoRAG](https://developers.cloudflare.com/ai-search/) is now in open beta, making it easy for you to build fully-managed retrieval-augmented generation (RAG) pipelines without managing infrastructure. Just upload your docs to [R2](https://developers.cloudflare.com/r2/get-started/), and AutoRAG handles the rest: embeddings, indexing, retrieval, and response generation via API.  
With AutoRAG, you can:  
   * **Customize your pipeline:** Choose from [Workers AI](https://developers.cloudflare.com/workers-ai) models, configure chunking strategies, edit system prompts, and more.  
   * **Instant setup:** AutoRAG provisions everything you need from [Vectorize](https://developers.cloudflare.com/vectorize), [AI gateway](https://developers.cloudflare.com/ai-gateway), to pipeline logic for you, so you can go from zero to a working RAG pipeline in seconds.  
   * **Keep your index fresh:** AutoRAG continuously syncs your index with your data source to ensure responses stay accurate and up to date.  
   * **Ask questions:** Query your data and receive grounded responses via a [Workers binding](https://developers.cloudflare.com/ai-search/usage/workers-binding/) or [API](https://developers.cloudflare.com/ai-search/usage/rest-api/).  
Whether you're building internal tools, AI-powered search, or a support assistant, AutoRAG gets you from idea to deployment in minutes.  
Get started in the [Cloudflare dashboard ↗](https://dash.cloudflare.com/?to=/:account/ai/autorag) or check out the [guide](https://developers.cloudflare.com/ai-search/get-started/) for instructions on how to build your RAG pipeline today.
