OPEN MEMORY, OPEN HARNESS the industry shifts to closed agent harnesses locking memory behind proprietary apis. https://x.com/hwchase17/stat…

Harrison Chase, co-founder of LangChain, discusses a trend in the AI industry where agent harnesses are becoming increasingly closed and proprietary, with memory systems locked behind vendor-specific APIs. The post advocates for open memory and open agent harnesses as an alternative approach, raising concerns about the implications of proprietary control over agent memory infrastructure. This reflects broader debates in the AI ecosystem around openness, interoperability, and vendor lock-in for agentic AI systems.

Agent harnesses dominate agent building and tie intimately to memory. Closed harnesses behind proprietary APIs force yielding control of age…

TLDR; memory = harness => keep your memory and harness on your side of the API.
