Could you build this?
No Achieving sub-15ms P75 recall on massive benchmarks like LongMemEval and Locomo requires custom graph-vector data structures, dedicated low-latency indexing, and specialized retrieval research.
What it would actually take: Requires low-level systems programming (C++/Rust) building a custom memory graph engine that unifies vector similarity search, temporal knowledge graphs, and entity resolution. It involves distributed memory architectures, custom embedding caching, optimized graph traversals, and benchmark validation pipelines managed by database and search engineers.
