NVIDIA unveils Rubin platform and Alpamayo at CES 2026

NVIDIA unveiled the Rubin platform in full production and introduced the Alpamayo open reasoning model family at CES 2026, positioning Rubin as a six-chip, extreme codesigned AI platform and Alpamayo as an open stack for level-4 capable autonomy.

• Main announcement:NVIDIA announced the Rubin platform is in full production (successor to Blackwell), a six-chip extreme‑codesigned system including Rubin GPUs (50 petaflops NVFP4 inference), Vera CPUs, NVLink 6, Spectrum‑X Ethernet Photonics, ConnectX‑9 SuperNICs, and BlueField‑4 DPUs; NVIDIA claims token generation costs ~one‑tenth of the prior platform and introduced AI‑native KV‑cache storage with up to 5x gains in tokens/sec, TCO performance and power efficiency. The company also introduced Alpamayo (R1 reasoning VLA, AlpaSim simulation blueprints) and said the first passenger car with Alpamayo on NVIDIA DRIVE will be on U.S. roads this year (the all‑new Mercedes‑Benz CLA).
• Background and details: The announcement was delivered at CES 2026 in Las Vegas; NVIDIA positioned Rubin as built “from the data center outward” and emphasized open models trained on NVIDIA supercomputers across domains (Clara, Earth‑2, Nemotron, Cosmos, GR00T, Alpamayo). Additional product notes: DGX Spark claims up to 2.6x performance for large models; partnerships and ecosystem mentions include Hugging Face, Siemens (expanded partnership), Palantir, ServiceNow, Snowflake, Boston Dynamics, Franka, Synopsis, Cadence, and others.
