Nvidia plans to invest in d-Matrix, a seven-year-old developer of AI server chips that competes with Nvidia, according to three people familiar with the deal. The move fits Nvidia's push to make its technology compatible with rival chip designers and pull them into its hardware ecosystem, for instance by having their chips share the same AI inference workload. The report says it is Nvidia's first investment in an AI inference chip startup since its $20 billion technology licensing deal with Groq last December.
