What it is
AWS designs its own AI accelerators through its Annapurna Labs unit: Trainium for training and Inferentia for inference, reducing dependence on Nvidia for internal and customer workloads. Trainium2 scaled in 2025 (notably the massive 'Project Rainier' cluster built with Anthropic), with Trainium3 on a 3nm node announced for 2025-2026. Chips are designed with Marvell/Alchip support and fabbed at TSMC; they undercut GPU pricing on EC2 for large-scale training.

Times are New York time. Free sources are pulled on the schedule shown by the pipeline runner (data/corpus/run_pipelines.py), which logs every run; paid sources run only with the owner's yes; filings and newsroom pages are re-read when a new document is filed.
Links come from the AI Systems Map ontology. Deals carry the filing's own wording and a quote, checked against the document; latest source 2026-10-26. Not investment advice.
