TL;DR
Cloudflare is building an operating system for AI agents.

After a massive week of announcements for their 15th birthday, the strategic direction is clear.

Here's the proof 🧵

Core Developer Platform & Compute:

- Cap'n Web: A new high performance RPC system for direct browser-to-server communication over WebSockets, designed to be faster than HTTP/REST.

- Node.js API Compatibility: Huge expansion in Workers, including node:fs (temp files), net, tls, crypto, and dns. Unlocks many existing npm packages like Axios by default.

The AI & Agent Stack:

- Code Mode: A new paradigm for AI agents. Instead of tool calling, LLMs generate TypeScript on the fly.

- Worker Loader API: A new API to securely execute that AI generated code in a dynamic, on-demand Worker sandbox.

- AI Index: An automated service to crawl your site, create vector embeddings, and expose your content via a standardized search API and MCP server for other AI agents to consume (RAG as a service).

@AWSreInvent

While I was watching the @AWSreInvent 2022 - Keynote with Adam Selipsky yesterday I wondered how many times the word "data" was said.

Well, the answer is: 241

Transcript was generated using whisper.cpp and on MacBook Air M1 it only took 4.75 minutes to transcribe a 2hr long video. Technology is amazing!

Enjoy the video.

Whole process is automated.

1. use ffmpeg to extract audio from video and output a wav file
2. use whisper.ccp to transcribe audio and output a srt file
3. use ffmpeg to generate segments with synced streams
4. use ffmpeg to concat segments into a final output
