AWS unveils Nova 2, Trainium3 UltraServers and AI Factories
20 days ago • ai-infrastructure
At re:Invent 2025, AWS unveiled Nova 2 foundation models. It also introduced Trainium3 UltraServers for accelerated training and deployment. AWS announced Graviton5 custom CPUs. It added AI Factories — an on‑prem option for running high‑performance AI in customer data centers. TechRadar Pro and IT Pro covered the announcements.
Together, these moves give AWS cloud and hybrid execution paths. Nova 2 expands model choices. Trainium3 UltraServers aim to speed training and inference at scale. Graviton5 targets improved performance per watt for CPU‑bound workloads. IT Pro noted global cloud infrastructure spending reached $102.6 billion in Q3 2025. AWS also reported its strongest quarter in three years.
For customers, the portfolio signals a push to simplify large‑model lifecycles from training to on‑prem deployment. Public availability windows and detailed benchmarks remain limited in current coverage. Expect partners and tier‑1 customers to test early integrations first. Monitor AWS documentation and follow‑up briefings for pricing and availability.
Why It Matters
- Hybrid deployment: AI Factories package cloud‑grade AI stacks for on‑prem use, reducing integration time for regulated or latency‑sensitive workloads.
- Training throughput: Evaluate Trainium3 UltraServers against existing GPU clusters to verify training speed, scalability, and total cost.
- Inference costs: Benchmark Graviton5 on CPU‑bound models to measure performance per watt and potential cost savings.
- Roadmap and procurement: Plan pilots now — expect early access programs and partner integrations before general availability; align procurement timelines accordingly.
