AI Engineer
I build systems thatthink in public.
Multi-agent pipelines, LLM integration and real-time event-driven architectures — and a running archive of the AI technology actually worth learning right now.
The radar · 13–19 October 2026
Ten things in AI worth your fortnight.
I read the releases so I only have to learn the ones that matter — new launches and the updates that quietly change how something is used. Each entry gets a full engineer-level write-up: what changed, what it costs, and when it is actually the right tool. Nothing gets deleted; it moves to the archive.

Who writes this
I'm Sagi — I take systems from plan to production, and keep them there.
I build production AI systems end to end: multi-agent pipelines on LangGraph, Claude and OpenAI APIs, Kafka and Redpanda streams, RAG on ChromaDB, and the FastAPI, Node and React layers that make them usable. B.Sc. Computer Science, 2026.
Before software I served as a fighter and team leader in the IDF's YAHALOM Special Operations Engineering Unit, leading a team of over 50 in classified operations. Alongside it, years of smart-home and low-voltage field engineering. Both taught the same lesson: own the system from plan to handoff.
The radar exists because keeping up with AI is now a part of the job, and most coverage is either a press release or a hot take. I write the version I wanted to read — what changed, what it costs, and when it is genuinely the right tool.
