RAG is dead. long live RAG — index, generate embeddings and start querying in just a few steps with the new @cloudflaredev autoRAG

With the new waitForEvent API in Workflows, your instances can wait for events from your agents (Pssst agents.cloudflare.com) await step.waitForEvent("wait until agent confirms", { type: "agent-confirms", timeout: "1 year" })

AutoRAG is now in open beta—fully-managed RAG pipelines so you can focus on building, not managing vector databases. 🗄️ Upload docs—we handle your embeddings and vector DB 🤖 Build AI chatbots with context-aware answers using API 👀 Monitor and analyze queries via AI Gateway

Been working on this for a couple weeks, yes a couple of weeks! This is the reason workers are so powerful, a team of 2 engs is capable of building a product from zero to production in record amount of time and scale with no sweat

Loving all the new things that are coming to Cloudflare Developers We can use Cloudflare for everything now. I can't think of a single thing that cannot be done with Cloudflare now.

Atari Missile Command game remake landed on Hackernews with 27K visitors & alot of AI end-game gameplay analysis 18 million tokens ! Ran into some rate limits with OpenRouter model providers using free models 😅 Cloudflare AI Gateway proxy cache saved ~20% of the requests 🤓

How we built an AI agent that creates daily content from our existing material (n8n + Cloudflare + AutoRAG setup) We’ve been experimenting with autonomous content workflows inside our business—and one of the most useful agents we built is one that turns raw content into polished
