亚马逊拟以70亿美元收购Decart
亚马逊70亿美元收购芯片优化公司Decart，目标是将Trainium成本每token降至低于英伟达硬件。
据《华尔街日报》报道，亚马逊正以约70亿美元的价格收购AI芯片优化公司Decart。此前亚马逊与英伟达和Anthropic的收购谈判均已破裂。Decart成立于2023年，其DOS优化栈声称可使模型在相同硬件上运行速度提升8倍，包括英伟达GPU、谷歌TPU和亚马逊Trainium芯片。亚马逊在2025年已向Decart提前提供了Trainium3芯片的访问权限。
WSJ just reported that Amazon is in talks to buy Decart for about $7B, after earlier talks with Nvidia and Anthropic collapsed.
Decart, founded in 2023 by Dean and Orian Leitersdorf and Moshe Shalev, builds software that lets developers move AI workloads between different chips.
Its DOS optimization stack claims to make models run up to 8x faster on the same hardware, including Nvidia GPUs, Google TPUs and Amazon Trainium. So basically with this acquisition, Amazon must be targetting to lower Trainium’s cost per token below Nvidia hardware.
Amazon has a head start on the technology, since AWS gave Decart early access to Trainium3 in 2025, and Decart adapted its model architecture to fit Trainium’s chip design.
Decart also builds real-time world models: Lucy for immersive experiences such as live video, and Oasis for physical AI and robotics simulation.
The price would sit about 75% above the valuation Decart set in May, when it raised $300M at an estimated $4B valuation.
Anthropic, Amazon’s close AI partner, wanted Decart’s technology to make its existing computing infrastructure handle more demand, but abandoned a $6B deal after due diligence.
The deal pays off for AWS only if Decart’s speedups hold on customers’ models, beyond Decart’s own video systems, and
