Give your agents memory they can move, merge, and prove they erased — a fast in-model working state plus a durable fact store, signed and auditable at the substrate.
Your LangGraph agent persists user state. A user invokes their right to be forgotten — can you prove the thread was deleted? Standard checkpointers can't. GRAFOMEM's does:
from langgraph.checkpoint.memory import MemorySaver from grafomem_checkpoint import GrafomemSerializer, GrafomemCheckpointSaver saver = GrafomemCheckpointSaver( MemorySaver(serde=GrafomemSerializer(private_key, key_id, trust, consent)) ) graph = builder.compile(checkpointer=saver) saver.delete_thread("user-123") receipt = saver.last_receipt("user-123") # signed, verifiable proof of the erasure
Every checkpoint signed and tamper-evident; delete_thread yields a signed state-transition receipt — a cryptographic proof the erasure operation occurred. (Proof of the transition — not a claim of media sanitization.) ▶ 60-second demo GIF →
Memory is the implementation; governance is the product.
A fast, fixed-size in-model state M, read y = Mq. Bounded, portable, mergeable, constant-size. Adaptive state as a movable, forkable, erasable object.
A lossless, queryable, model-agnostic fact store. Auditable, survives model upgrades.
Signed transition receipts on the working tier, cryptographic erasure certificates on the durable tier. Both tiers, one audit surface.
GRAFOMEM ships an executable conformance suite (GMP): "supports capability X" means passes the test for X — two-sided, bootstrap-CI. It's how the durable tier earns trust, and the basis for signed capability reports in GRAFOMEM Cloud.
(This is a capability of the platform — not the pitch. The pitch is the runtime above.)
The runtime: working memory + durable facts + governance primitives. Self-host anywhere, forever free. pip install grafomem · langgraph-checkpoint-grafomem · TS .gfm verifier.
Fair Source (FSL-1.1-Apache-2.0) — use, modify, self-host freely; only a competing managed service is restricted. The spec, .gfm format, and conformance suite are open (Apache/MIT).
Hosted, multi-tenant, governed: decision trail, erasure proofs, governance gateway, regulatory reports, third-party attestation. You point your registry at the cloud — a config change, not a migration.
