In late October, Samsung said its 2027 HBM supply is already sold out alongside multi-year memory contracts with 10 large customers, and Amazon disclosed an up-to-$80 billion secured loan facility for 2027-28 hardware purchases.

Microsoft, Alphabet, Meta and Amazon reported roughly $207 billion of third-quarter capital spending between October 21 and 29, and the binding constraint they described was supply, from delayed third-party capacity to chips, not any reluctance to spend.

Between October 26 and 29, Broadcom backstopped up to $43 billion of a $63 billion vehicle that buys its chips for Anthropic, Nvidia and AMD put $4 billion into Meta's stock sale, and Nvidia was reported in talks to guarantee Nscale debt for an Anthropic site.

A 110-item infrastructure gatekeeping list that pulled 294K views on X is a verbatim copypasta of a July post with 47 likes, and its 16 headline items grade out at 7 absorbed and 2 still biting against dated platform changelogs.

Notion embedded coding agents into its workspace in a few weeks with the Cursor SDK, which turns the harness behind Cursor into a callable runtime so an @mention can plan, build, test and open a PR, a bigger shift than any model release.

An operator playbook for Mastra across six TypeScript codebases and the full 1.x line, covering memory's four layers, supervisors, MCP on both ends, RAG and evals, auth, observability, the 1.x migrations and the production bugs that taught the most.

Three different products spent two years fighting over the phrase 'LLM router': aggregation won at a $1.3B valuation, gateways became table stakes, and the most-hyped category, semantic cost-routing, quietly froze on GitHub.

On June 7, 2026, X renamed the agent loop 'loop engineering' and called it the successor to harness engineering; The Deep Feed ran 47 Claude Code loops in a sandbox and found the naming churns while three of four technical claims hold, one to the cent.

Two near-simultaneous coiners (Mitchell Hashimoto and Viv Trivedy), seven convergent voices and twelve coding agents that built the same primitives independently mark a discipline that crystallized in nine months.

Polymarket swapped its trading stack in one hour on April 28, and three days later V1 trades have hit zero while thousands of bot wallets sit silent on V2, which makes the migration look less like an upgrade than a cull.

Every agent-memory tutorial opens with a vector DB, but that is a product opinion rather than a default; mature agent runtimes start elsewhere, and Qdrant or sqlite-vec earns its keep only past roughly 50K episodic items.

Sixteen months in, MCP counts 97M SDK downloads, 20,000+ servers, six framework attempts and one unsolved auth problem; this map covers who is shipping and where the protocol breaks at scale.

Fifteen open-source deep-research agents reduce to four architecture archetypes, two of which are dead ends, and this field guide sorts the agents by archetype so the right one is easier to pick.
