Open-source libraries that bound what AI agents read, keep their memory on your hardware, and record their actions for verification.
What it is
Perseus Computing builds Telarch, an open-source infrastructure for AI agents consisting of three libraries: Harpe, Kibisis, and Argus. Harpe bounds what a model reads by choosing what goes into each model call under a token budget. Kibisis keeps agent memory on your own machine using AES-256-GCM encryption in a SQLite file. Argus records what an agent did in an append-only ledger that detects edits. The company publishes all code, benchmarks and raw results under the MIT License.
Systems
- Harpe: chooses what an AI agent reads under a token budget with consistent results
- Kibisis: keeps agent memory on your hardware with AES-256-GCM encryption
- Argus: append-only record that detects edits with cryptographic verification
- No network code by default for local and disconnected use
- MIT License with published code, benchmarks and raw results

Quick answers
- What are the three libraries that make up Telarch?
- Telarch consists of three libraries: Harpe, which bounds what a model reads by choosing what goes into each model call under your token budget; Kibisis, which keeps agent memory on your own machine with AES-256-GCM encryption in a SQLite file; and Argus, which records what an agent did in an append-only ledger that detects edits.
- Is Telarch open source?
- Yes, Telarch is released under the MIT License with no network code, designed for local and disconnected use.
- How has Telarch been evaluated?
- Telarch has been evaluated on standard benchmarks including LongMemEval, LoCoMo, BEAM (100K to 10M tokens), and MemoryAgentBench, showing encrypted vaults match plaintext index accuracy and exceed full context by +4.9 to +20.4 points on long contexts.
