CURSOR'S WAR CHEST, XAI'S REDEMPTION

Cursor is the most operationally successful software company of the AI era. Its founders looked at the path to $100 billion and decided they weren't willing to underwrite it. They sold to xAI for $60 billion in a deal considered to be good for everyone. The deal gives xAI an application surface to put in front of public market investors before the SpaceX IPO, and it gives Cursor a sponsor with compute and a non-competing model lab.

KV CACHE LOCALITY: THE HIDDEN VARIABLE IN YOUR LLM SERVING COST

KV cache locality is a multiplier on existing hardware. The same GPUs serving the same model and handling the same traffic can produce measurably different throughput and latency depending on which GPU gets which request. 'Balanced' and 'efficient' are not the same thing when every request carries thousands of tokens that might already be cached somewhere in the cluster. This post discusses the cost of recomputation, how to measure it, and what changes when load balancers understand token locality.

NEW FRONTIER MODELS ARE FASTER, NOT MORE RELIABLE, AT SPATIAL BIOLOGY

GPT-5.5 nearly halves runtime on SpatialBench relative to GPT-5.4, but its accuracy remains about the same. Opus 4.7 is similarly tied with Opus 4.6. Improvements and spatial biology are unlikely to come from general reasoning gains alone. It will likely require explicit training on statistical design, platform-specific analysis stems, replicate-aware differential testing, and other spatial biology knowledge.
