The Helios rack combines 72 MI455X GPUs with EPYC Venice CPUs and Pensando networking — 4,600 CPU cores and 18,000 GPU compute units per rack. OpenAI, Meta, Oracle, Anthropic, and Microsoft all showed up as customers. AMD also announced a $5B investment in Anthropic and a commitment to deploy up to 2GW of MI450-series GPUs to run Claude, with the first gigawatt starting H1 2027. Microsoft is integrating Helios into Azure via a new ND MI455X v7 VM family. AMD shares fell roughly 4% after the announcements — Nvidia's Vera Rubin is already shipping at scale, and AMD has a history of strong hardware launches that take time to translate into real market share.

The practical effect: session IDs are gone from the server side, values are read from HTTP headers, and Redis sessions are eliminated — no more database reads and writes on every initialize call. Client connections can now do parallel handshakes instead of sequential session initialization. All tier-1 SDKs maintain backwards compatibility, and the spec has been public since May. Stateful session management has been a real barrier to production MCP deployments at scale; this removes it.

Targets are internet-exposed PLCs from Rockwell, Schneider Electric, and Siemens. CISA has since expanded the alert beyond Rockwell to cover a broader range of industrial kit. The group Handala has claimed credit for at least two incidents including a Cal Water breach. The practical guidance is blunt: remove internet-exposed PLCs, enforce phishing-resistant MFA on remote access, and audit identity and service-provider relationships.

The core design separates Query Processors, Storage Nodes, Adjudicators, Journals, and Crossbars into independently scalable services. DSQL uses AWS TimeSync for physical clock synchronization to enable 0-RTT consistent reads, and optimistic concurrency control with snapshot isolation so there's no lock contention. The tradeoffs are real: hard limits of 3,000 rows and 10MiB per transaction, OCC retry overhead on hot keys, and foreign keys create coordination friction. Strong linearizable consistency is the default — the paper argues that improvements in time distribution and datacenter networking have made the old eventual-consistency tradeoff obsolete.

The cooldown is on by default and configurable via dependabot.yml.
