kore-mind 0.3.0

Persistent memory + emergent identity engine for any LLM

kore-mind

Persistent memory + emergent identity engine for any LLM.

One file = one mind. SQLite-based. Zero config. Zero external dependencies. Runtime-agnostic.

Part of kore-stack — the complete cognitive middleware for LLMs. pip install kore-stack for the full stack, or install individually:

Install

pip install kore-mind          # just the memory engine
pip install kore-stack         # full stack: mind + bridge + SC routing

Usage

from kore_mind import Mind

mind = Mind("agent.db")

# Register experiences
mind.experience("User works on complexity theory proofs")
mind.experience("User prefers direct, concise answers")

# Recall relevant memories
memories = mind.recall("proof techniques")

# Reflect: decay old memories, consolidate, update identity
identity = mind.reflect()
print(identity.summary)

# Forget: explicit pruning
mind.forget(threshold=0.1)

Core concepts

• Memory has a lifecycle: salience decays over time. Unused memories fade. Accessed memories strengthen.
• Identity is emergent: not configured, but computed from accumulated memories.
• reflect() is the key operation: decay + consolidation + identity update.

API

Method	Description
experience(text)	Something happened. Record it.
recall(query)	What's relevant now?
reflect(fn)	Consolidate. Decay. Evolve.
identity()	Who am I now?
forget(threshold)	Explicit pruning.
scoped(source)	Filtered view per user. Same DB.
traces()	Query operation traces.

Semantic Search (v0.3)

Built-in embedding providers — semantic recall works with one line:

from kore_mind import Mind, numpy_embed

# Zero-dependency option (numpy only, no external service)
mind = Mind("agent.db", embed_fn=numpy_embed())

mind.experience("me gusta el café por la mañana")
mind.experience("Python es un lenguaje de programación")

# Finds "café" even searching for "bebidas calientes"
results = mind.recall("bebidas calientes")

Three providers available:

from kore_mind.embeddings import numpy_embed, ollama_embed, openai_embed

# 1. numpy_embed — zero dependencies, deterministic, fast
mind = Mind("agent.db", embed_fn=numpy_embed())

# 2. ollama_embed — local Ollama server (falls back to numpy if unavailable)
mind = Mind("agent.db", embed_fn=ollama_embed())

# 3. openai_embed — cloud, max quality (requires API key)
mind = Mind("agent.db", embed_fn=openai_embed(api_key="sk-..."))

v0.2 Features

Per-user filtering

Each user gets their own "mind" — same database, different context.

# Option 1: default source
mind = Mind("agent.db", default_source="carlos")
mind.experience("Likes Python")  # automatically tagged to carlos
mind.recall("Python")            # only carlos's memories

# Option 2: scoped view
alice = mind.scoped("alice")
alice.experience("Prefers Rust")
alice.recall()  # only alice's memories

Observability

Full tracing of every operation. Zero overhead when disabled (default).

mind = Mind("agent.db", enable_traces=True)

mind.experience("Something happened")
mind.recall("what happened")

# Query traces
traces = mind.traces(operation="recall")
for t in traces:
    print(f"{t.operation} took {t.duration_ms:.1f}ms")

# Filter by source
traces = mind.traces(source="carlos", limit=50)

Smart Cache (storage layer)

Hash-based cache with TTL, per-user isolation, and hit counting. Used by kore-bridge for token savings.

from kore_mind.models import CacheEntry

entry = CacheEntry(
    query="What is P vs NP?",
    response="It's an open problem...",
    query_hash="a1b2c3d4",
    source="carlos",
    ttl=3600.0,
)
mind._storage.save_cache_entry(entry)
found = mind._storage.find_cache_by_hash("a1b2c3d4", source="carlos")

Rate Limiting (storage layer)

Query logging with temporal window counting. Used by kore-bridge for cognitive rate limiting.

Models

Model	Description
Memory	A memory with lifecycle (salience, decay, tags, embedding)
Identity	Emergent identity (traits, summary, relationships)
MemoryType	episodic, semantic, procedural
Trace	Operation trace (operation, duration, source, metadata)
CacheEntry	Cache entry (query, response, hash, TTL, hit count)

Backward compatibility

All new parameters have defaults that preserve v0.1 behavior:

# This works exactly the same as v0.1
mind = Mind("agent.db")
mind.experience("fact")
mind.recall("query")

Part of kore-stack

Package	What it does
kore-mind (this)	Memory, identity, traces, cache storage
kore-bridge	LLM integration, cache logic, rate limiting, A/B testing
sc-router	Query routing by Selector Complexity theory
kore-stack	All of the above, one install: pip install kore-stack
