A weekend pricing update can be easy to miss—until the bill arrives. AWS applied an approximately 15% price increase affecting EC2 Capacity Blocks for ML (a way to reserve GPU capacity for a future start time) in early January 2026, with reporting highlighting the unusual timing: a Saturday update. This matters for teams running GPU-heavy workloads—especially those relying on reserved, business-critical capacity rather than casual experimentation. TL;DR The change discussed here is about EC2 Capacity Blocks for ML , not necessarily every GPU option in AWS. The increase was reported as ~15% , and the timing (a weekend update) can reduce customer reaction time. The practical impact is predictable: higher run costs, tighter budgets, and more urgency around cost visibility and capacity planning. Top 10 most important things to know This is about Capacity Blocks for ML (reserved GPU capacity), not a blanket “all GPU prices” change...

NVIDIA’s CUDA 13.1 introduces a tile-based approach to GPU programming that aims to make high-performance kernels easier to express than traditional SIMT-style thinking. Instead of focusing primarily on “what each thread does,” developers can express work in cooperating chunks (tiles) and rely more heavily on the toolchain to handle the mapping and coordination details. This is a technical shift, but it has ethical consequences that are easy to miss. When powerful acceleration becomes easier to use, it changes: Who can build high-performance AI systems How fast teams can iterate and deploy How large a system can scale (and how quickly mistakes can scale with it) How auditable the pipeline remains under pressure to optimize for throughput In other words, tile-based programming doesn’t create ethical risk by itself. The risk emerges when organizations use the new productivity and performance headroom to ship faster than their validation, governance, and ac...
