Another week, another frontier model. As Anthropic’s Claude Opus 4.7 chases enterprise depth and OpenAI turns ChatGPT, GPT‑6 and GPT‑Rosalind into the ambient verbs of digital work and lab science, the contest is no longer IQ scores. It is which unseen layer we quietly let sit beneath institutions.
ShinyHunters has exposed a critical weakness in cloud systems. The McGraw Hill breach shows how misconfigured Salesforce portals enabled large scale data leaks, with no software flaw to fix. This marks a shift toward exploiting common operational gaps rather than rare vulnerabilities.
Anthropic’s Mythos clampdown, April’s record Patch Tuesday and Nvidia’s Blackwell‑to‑Rubin GPU roadmap mark a turning point in cyber defence, exposing how deeply allied nations now rely on US‑controlled, agentic AI to detect and counter zero‑day threats.
Ayar Labs has secured $500 million in a Series E round to scale its co-packaged optics technology. Backed by NVIDIA and AMD, the company is replacing traditional copper interconnects with light-based data transmission to solve the growing power and bandwidth crisis in AI data centres.
Ayar Labs has closed a $500 million Series E funding round to accelerate the production of its optical I/O technology, which aims to solve the escalating power and data bottleneck crisis in large-scale AI systems.
Ayar Labs, a US-based semiconductor company founded in 2015, develops co-packaged optics (CPO) that use light to transfer data between chips instead of traditional copper wires. The company's core products, the TeraPHY optical I/O chiplet and SuperNova light source, are designed to be integrated directly into the packages of advanced AI processors and switches.
The Update: Ayar Labs has raised $500 million in a Series E round, bringing its total funding to $870 million and valuing the company at $3.75 billion. The round was led by Neuberger Berman and included new strategic investments from semiconductor giants AMD, Alchip, and MediaTek, alongside existing backer NVIDIA. Key institutional investors such as ARK Invest, Insight Partners, and the Qatar Investment Authority also participated.
"AI infrastructure is hitting a power wall driven by interconnect inefficiency. As bandwidth demands explode, copper becomes the bottleneck, consuming too much power and limiting AI throughput per watt and per dollar. Co-packaged optics overcomes these barriers, enabling thousands of GPUs to operate as a unified system." - Mark Wade, CEO and Co-founder, Ayar Labs
The capital will be used to scale high-volume manufacturing and testing of its co-packaged optics (CPO) solutions, which replace bandwidth-limited copper interconnects with high-speed, low-power optical links. The company plans to expand its global operations, including a new office in Hsinchu, Taiwan, to meet the demands of hyperscale AI customers. The technology is critical for enabling thousands of GPUs to operate as a single, unified system, overcoming the physical limitations of copper that create performance bottlenecks and drive up power consumption in modern data centres.
In an exclusive with @WSJ, we detailed how our CPO technology is solving one of the biggest hardware issues that’s causing bottlenecks in AI and revolutionizing the way chips are connected inside server racks.

Why it Matters: The significant investment from major chipmakers like NVIDIA and AMD signals strong industry conviction that optical I/O is a necessary technology for the future of AI infrastructure. As AI models grow in complexity, the electrical resistance and power draw of copper wiring become a fundamental barrier to scaling performance efficiently.
Ayar Labs' approach of integrating light-based communication directly onto the chip package addresses this power wall head-on, promising substantial improvements in data throughput per watt. This shift is not just an incremental upgrade; it represents a foundational change in data centre architecture required to sustain the progress of AI.
