XY is a fast, composable GPU-accelerated interactive plotting library for Python, designed for web and notebooks, handling up to 10 billion points with pan and zoom.
This paper proposes that the KV cache in transformers acts as a notebook of memoized conclusions, enabling surgical editing and composition without full recomputation. The method achieves significant latency reductions while preserving decision equivalence across model scales.
HarnessX is a foundry for composable, adaptive, and evolvable AI agent harnesses that uses compositional primitives and trace-driven evolution to improve agent performance. Across five benchmarks, it achieves an average gain of +14.5% (up to +44.0%), demonstrating that runtime interface evolution is a complementary lever to model scaling.
