Anthropic has hired Amir Salek, the engineer who established Google's custom silicon program and led the development of its first seven Tensor Processing Unit (TPU) generations, to expand the AI lab's in-house semiconductor engineering initiatives.
Salek joins Anthropic's compute infrastructure organization, reporting to James Bradbury. The appointment signals that Anthropic is laying foundational engineering capability for proprietary AI accelerator design alongside its existing multi-provider cloud infrastructure.
Background in Custom Accelerator Design
Salek brings deep expertise in large-scale domain-specific architectures:
- Google TPU Leadership: Salek managed Google's custom chip division until 2022, overseeing seven hardware iterations of the Tensor Processing Unit family that underpin Google's internal ML training and inference workloads.
- Nvidia System-on-Chip Founding: Prior to his tenure at Google, Salek founded and managed Nvidia's System-on-a-Chip (SoC) design team.
- Private Equity and Defense: After departing Google in 2022, Salek served as Senior Managing Director at Cerberus Capital Management, focusing on supply chain security and technology investments.
Strategic Shift Toward In-House Silicon
Frontier AI labs face severe infrastructure bottlenecks as compute requirements scale. Developing in-house silicon architecture provides several operational advantages:
- Workload Specialization: Custom ASICs can be optimized specifically for transformer architectures, attention mechanisms, and low-precision arithmetic formats without supporting legacy graphics or general-purpose instruction sets.
- Margin and Unit Economics: In-house chip designs reduce reliance on high merchant-silicon premiums, lowering per-token inference and training costs over multi-year operational cycles.
- Supply Chain Redundancy: Direct engagement with foundry partners like TSMC provides additional capacity buffers during global accelerator shortages.
The hiring aligns Anthropic with competing frontier labs pursuing custom hardware. OpenAI recently detailed its custom inference accelerator (developed in partnership with Broadcom) at Hot Chips 37, while hyperscalers including Google, Amazon, and Microsoft continue expanding proprietary TPU, Trainium, and Maia deployments.
Continued Multi-Vendor Cloud Infrastructure
Anthropic has stated that internal silicon exploration operates alongside, rather than replaces, its external hardware partnerships. The company continues to deploy Claude across a diverse mix of commercial infrastructure:
- Amazon Web Services: Primary training and inference deployments utilizing AWS Trainium chips and Nvidia GPU clusters.
- Google Cloud: Deployment across Google TPU infrastructure.
- Alternative Hardware Partners: Preliminary procurement agreements with specialized accelerator vendors, including an initial $250 million contract with UK-based chip startup Fractile.
