AMD pitches its MI400 series as an open alternative to CUDA
According to the November 14 Rio Rundown newsletter, AMD is positioning its MI400 Series as an open-source alternative to Nvidia's CUDA ecosystem.
The same issue says AMD and Meta are optimizing PyTorch, Triton and ROCm for Instinct MI350X GPUs, with day-0 support already delivered for Meta's Muse Spark Open models. It also mentions the SGLang Consortium, which unites major tech firms around open-source software for efficient inference, and the release of open weights for Inkling 2 Small from Thinking Machines Lab. The newsletter frames this as strengthening local AI infrastructure.
