Story

Published June 23 on the Hugging Face blog, CUGA emphasizes practical, working implementation patterns over a heavyweight framework. (Hugging Face) For builders who want reference architectures instead of abstraction, two dozen functional examples beats another framework you have to learn. PlanBench-XL also landed this week, a 327-task benchmark across 1,665 tools that isolates the "find and sequence the right tool" failure mode in large registries (arXiv). Both point at the same reality: tool retrieval at scale is the hard part now, not single-call accuracy.
