The reference server, run for you. PostgreSQL + pgvector under the hood, the full GMP memory model on top, and the same conformance the standard verifies — no infra, no ops, no eval guesswork.
The reference server is open source — self-hosting is a first-class, free option, forever. GRAFOMEM Cloud is for teams who want the same conformant memory without owning the Postgres, the pgvector tuning, the scaling, or the conformance runs.
Everything in the open GMP memory model, hosted and operated — and continuously checked against the same suite and public corpus that grade every other backend.
HNSW approximate nearest-neighbour, O(log n) retrieval, tuned and scaled for you.
Every deploy graded against GMP — M8 = 1.000, identical to the SQLite reference.
Strict per-tenant isolation with scoped gfm_ API keys.
The full GMP memory model: valid-time travel and supersession chains.
Ed25519-signed writes you can audit, end to end.
Batched embedding and single-transaction write_many() for fast backfills.
Transparent counters, quotas, and sliding-window rate limits.
Per-tenant conformance history, at a glance.
Verified, not asserted. GRAFOMEM Cloud certifies against the open GMP standard exactly like any other backend — same suite, same public corpus, no privileged treatment. See our row in the public registry ↗
GRAFOMEM Cloud is in private beta. Tell us what you're building and we'll get you an API key and onboarding.
We'll be in touch about beta access.
Meanwhile, the standard is open — explore GMP or self-host the reference server free.
