Infinity raises $15M at a $100M valuation to build a CUDA-style, chip-agnostic kernel software stack for universal AI inference, backed by Touring Capital, Principal VC, and researchers from OpenAI/Anthropic, with 26 employees and a notable customer (D-Matrix).
Microsoft and NVIDIA unveil RTX Spark-powered Windows PCs and DGX Station for Windows, delivering up to 1 petaflop of AI performance, up to 128GB unified memory, and broad OEM support, with a clear focus on on-device AI, security, and creator/developer workloads.
A performance-centric, first-principles framework for diagnosing DL infrastructure bottlenecks (compute, memory bandwidth, overhead) that emphasizes operator fusion and JIT tooling to push GPUs toward compute-bound regimes, backed by concrete hardware figures and practical profiling guidance.
A technical blog post shows a 16% throughput and ~11% end-to-end latency improvement in multimodal inference by caching CUDA IPC pool handles in a Python dict, reducing host-side overhead in SGLang.
AWS Trainium3 unveils switched-scale-up rack architectures (NL32x2 Switched and NL72x2 Switched) with Gen1/Gen2/Gen3 switch trays, advancing memory bandwidth and per-TCO performance while expanding software openness and ecosystem bets to challenge Nvidia and AMD in the datacenter AI race.
A dense, data-driven diary of training a GPT-2 small base model from scratch on a single RTX 3090, detailing data prep, tokenization, sequence handling, speed tests, checkpoints, validation, and comparisons to OpenAI weights, with conclusions about feasibility and gaps to achieve a true Chinchilla-optimal train.
