multi-agent

Multi-agent architectures have quietly become the default for anything more ambitious than a single-turn chat, but when to reach for them — and how to keep them from blowing up your token budget — is still guesswork in most codebases. In this 26-minute LangChain talk, Colin Flaherty lays out a clean, prescriptive mental model built on top of Deep Agents: sub-agents are just a way to parallelize work and control what returns to the parent context, and there are exactly four patterns worth memorizing....

Google DeepMind’s podcast sat down with Nenad Tomašev, senior staff research scientist at DeepMind, to ask a question that’s about to stop being theoretical: what happens when millions of agents start transacting, negotiating, and delegating to each other — not just to humans? The episode is one of the rare ones where a research lab talks publicly about open problems instead of product launches. With Gemini Spark, Antigravity, OpenClaw-style frameworks, and dozens of vendor agent runtimes all shipping, the multi-agent layer is now the part of the stack with the least standardization and the most unknown failure modes....

DeepMind’s roughly six-minute overview video, “Generating novel scientific hypotheses with Co-Scientist,” opens not with a product demo but with a confession from scientists: the firehose of new literature has long since outpaced the humans trying to drink from it. One researcher describes having “hundreds of Chrome tabs and papers open.” Another says the amount of knowledge needed to stay at the frontier of a field now doubles roughly every two months....

Weekly Video Notes — a short article distilling one talk from the weekly digest. Source video and key frames are embedded throughout. What’s better than one GPT-5.5 Pi coding agent? Two GPT-5.5 Pi coding agents that can actually talk to each other. That’s the opening provocation of IndyDevDan’s latest video, and it leads into a deceptively simple shift in multi-agent design: drop the orchestrator, give every agent a two-way communication channel to every other agent, and let the best information win....
