Frequently Asked Questions
Parametric Memory is built on cryptographic foundations. Every memory operation is verifiable via RFC 6962 Merkle proofs, making memory auditable and tamper-evident — critical for regulated AI systems. We include Markov-chain prediction (64% hit rate) to anticipate what your AI will need next. MCP support is native, not bolted on. Your substrate runs in isolated containers — not shared infrastructure. And pricing is flat-rate: no per-query fees that explode as your system scales.
