Cognitive Architecture Python Packages

cognee

Cognee is the open-source AI memory platform for agents. Give your AI agents persistent long-term memory across sessions with a self-hosted knowledge graph engine.

neuro-cortex-memory

Bio-inspired cognitive architecture for LLM agents providing embodied sensation, homeostatic drives, and brain-modeled persistent memory enable cross-session learning without fine-tuning. Works with robots like the Reachy Mini or headless.

buddhikernel

A composable supervisor kernel that rations cognition across agentic work: the discriminative-executive layer for LLM agents.

phoenix-os

An AI that feels like it knows you -- cognitive architecture with memory as the nervous system.

zikkaron

Biologically-inspired persistent memory engine for Claude Code. 26 cognitive subsystems, Hopfield networks, predictive coding, causal discovery, successor representations, all running locally over SQLite.

pysakshi
