About
Ayar Labs develops optical interconnect chiplets that replace copper wires inside AI servers and data centers with silicon photonics — eliminating the bandwidth wall that throttles GPU cluster performance. The company raised $500 million in Series E financing in March 2026 at a $3.75 billion valuation, with both NVIDIA and AMD as co-investors — the two dominant AI chip companies betting on Ayar's technology appearing inside next-generation accelerators.
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.

Available as a free web and mobile app with a ChatGPT Plus subscription ($20/month) unlocking GPT-4o, advanced voice mode, image generation, and longer context.
