Read the full description
Hindsight is open-source memory that lets AI agents learn from experience, #1 on every dataset of the Agent Memory Benchmark. Today it's 1.0, and the API is a promise. We're also launching Hindsight Memlake, a storage engine written in Rust that keeps agent memory in object storage: 100M memories at under 100 ms p99, with no database, consensus cluster or leader. Self-host it free, start on Hindsight Cloud with free credits, or run it in your own cloud with Enterprise.

No Building high-performance agent memory architectures and a custom storage engine in Rust capable of managing 100M memories on object storage requires deep systems and database engineering expertise.
What it would actually take: The architecture requires a custom low-latency vector/relational storage engine written in Rust or C++, tiered caching algorithms to manage object storage (S3/GCS) latency, and complex retrieval algorithms benchmarked against state-of-the-art agent recall tasks. Specialized knowledge in storage primitives, concurrency, vector indexing, and memory compaction is essential.
