Replaying a real session to find the memory cost we never counted
Long sessions kept getting reset after our memory fixes. We nearly capped the context, until a local replay of a real session pointed at tokenization.

EngineeringRead articleA service agent can't teach itself from memory. Its context comes in five owned layers, and signals from service are reviewed, evaluated and shipped as new versions.
BusinessDeepSeek's Super-agent separates the entry point from the work and pulls apart the memory layers an agent used to cram into one window. The potential it unlocks is cashed in by the main session's memory, which we plan to build on relationships, ontology and phenomenon.
ProductSorted by whom they represent, agents come in two kinds, personal and service. Building them takes two more - a shared base, and an identity with no brain of its own that the AI you already use can drive.
ProductThe docs say 128 MB, yet our sessions crossed it without always being killed. We deployed a throwaway probe to find out: the reset line fell between 254 and 300 MiB, what matters is how much data is alive at once, and recorded peaks are always a lower bound.
EngineeringA user said our agent kept stopping halfway through. Our logs showed no cause of death; the platform metrics showed memory errors, and heap snapshots showed three sources. This is how we tracked it down, the traps we hit, and the numbers after the fix.
EngineeringA service agent assembles what used to be scattered across people, documents, software and data into one system. It is easy to scale and hard to rebuild, its complexity lets investment accumulate, and when a provider holds all of it, it is an asset.
BusinessPersonal agents will synthesize every provider's information for consumers, and a buyer's agent is loyal to the buyer. Service providers need a context system they can build, accumulate and iterate on, and the service agent is what carries it.
BusinessBeyond personal agents, service agents are coming too. One seeks change, the other seeks constancy, and they cannot be merged.
