The Librarian Test
Bring the right books, check the card, truly withdraw the withdrawn. GateMem scores all three at once — and Velixar is the only librarian that passes the whole test.

The Real Problem With Long Context
Long context beat Velixar on GateMem, and we published it. The real question isn't benchmark scale — it's what happens to cost, latency, and governance as history grows.

We Thought a Bigger AI Model Would Win. The Benchmark Said Otherwise.
We benchmarked Velixar on HaluMem expecting a bigger extraction model to win. It didn't — and our obvious fix for the weakest category made things worse. What component isolation taught us.

What the Numbers Actually Say
Velixar on HaluMem — extraction leads the field, QA and Update don't, and we ran down both confounds before publishing either result.

The Corpus Outlives the Model
98.3% recall, a 97.4% complete evidence set, and a 22.2-point spread in what seven models do with them — the case for a component-isolated evaluation standard.

What Memory Is Worth: +55 Points, Same Model
Hold the reader constant and toggle only the memory: 13.9% closed-book becomes 68.9% with Velixar. Underneath it, retrieval at 98.3% recall@25 — and the measurement conditions nobody else prints.

Same Memory. Same Questions. 22 Points Apart.
We ran one memory system through seven reader models and seven judges — all 49 combinations. The scores say more about the industry's benchmarks than about any memory system.

80.6% Answered. 98.3% Retrieved. Two Numbers, Two Different Jobs.
With a frontier reader, Velixar-backed answers reach 80.6% end-to-end. Underneath: 98.3% retrieval recall@25, a +55-point lift over the same reader without memory, and every condition printed.

Measuring memory, in the open
Our first research report is up: why end-to-end memory benchmark scores are joint measurements — and how we evaluate Velixar honestly.
