Agent context layer platforms BetterDB Valkey and OpenKnowledge launch for memory and retrieval

BetterDB released an open-source Valkey-native context layer for AI agents supporting agent memory, semantic caching, and typed retrieval without vendor lock-in, while OpenKnowledge launched a markdown editor with Claude, Codex, and agent integrations. Both platforms address infrastructure gaps in managing long-term agent context and knowledge retrieval across multiple tools.
