OCI MSA Alliance: A Revolutionary Turning Point in AI Infrastructure

On March 12, 2026, a significant turning point in the artificial intelligence (AI) industry occurred with the formation of the Optical Compute Interconnect (OCI) Multi-Source Agreement (MSA), or OCI MSA for short . This alliance brings together leading global players including AMD, Broadcom, Meta, Microsoft, NVIDIA, and OpenAI, with the goal of building an open standard for next-generation AI infrastructure.

As large-scale language models (LLMs) advance to the level of superintelligence, traditional copper-based connections are reaching their physical limits in terms of transmission distance, creating a 'bottleneck' in AI cluster architecture. OCI MSA was created to promote the transition from copper to optical-based connections, enabling more flexible and efficient system scaling.

OCI's specifications are designed to optimize power consumption, latency, and cost simultaneously. The core difference is the shift from a module-centric to a silicon-centric model, enabling tight integration of optics with processing chips and networks.

Establishing an interoperable optical interface protocol makes it easier for hyperscale data centers to combine the best processors (XPUs) and converters from multiple vendors. The OCI MSA 's technical roadmap is ambitious:

• OCI GEN1: Supports speeds of 200Gbps in each direction.
• OCI GEN2: Achieving 400Gbps and aiming for 800Gbps per fiber.
• Future: Expanding to 3.2Tbps and beyond.

Representatives from founding members such as AMD, NVIDIA, and OpenAI all emphasized that an open, multi-vendor optical connectivity ecosystem is vital for building future AI supercomputers. According to Richard Ho, Head of Hardware at OpenAI, the OCI MSA will play a crucial role in helping the industry build AI systems robust enough to achieve general artificial intelligence (AGI).

With the concerted efforts of tech giants, OCI MSA promises to create a standardized roadmap, minimize integration risks, and shorten development cycles for the entire global AI infrastructure supply chain.
