Harrison Chase on building frontier harnesses: context layers, evals, online learning
VeryWellVersed · x · 2026-09-27
LangChain founder @hwchase17 shared takeaways on building frontier AI harnesses: a harness is orchestration logic that gets the right context to the model at the right time; start with an off-the-shelf harness over model-specific SDKs; static context files are no longer enough—agents need online-learning context layers; and strong evals are essential for benchmarking and hill-climbing.
