Latest change
Motif open-sourced a shared, versioned memory store for teams of coding agents on Sept 21, following MemHub's commercial persistent-memory product and a kernel-managed-memory research paper earlier in the month.
Earlier contextThe story so far
In early September a startup and an academic paper both proposed giving AI agents persistent, shared memory instead of siloed per-session context. The pitch: context one agent learns should stay usable by every other agent on the same team, not vanish when a session ends.

What to watch — open questions
- Does Motif or MemHub define a conflict-resolution model for concurrent agent writes to shared memory?
- Does kernel-managed shared memory, the arXiv proposal, ship in any production agent framework, or does it remain research?
