icm-llm 0.1.1

O(1) hyperbolic memory for any LLM — 260 bytes per session forever

Infinite Context Memory (ICM)

O(1) hyperbolic memory for any LLM. 260 bytes per session. Forever.

---

Demo

Try ICM right now — 4 ways:

Method	Command
pip	pip install icm-llm
Docker (full stack)	docker compose up -d && open http://localhost:8000
Colab (browser)
CLI (local)	icm-demo or icm-chat or icm-server
Python (code)	pip install icm-llm && python -c "from hyper_ssm.conversation_memory import InfiniteContextMemory; m = InfiniteContextMemory(); print(f'{m.memory_size_bytes}B fixed-state O(1) memory')"

# One-liner to see O(1) memory in action:
pip install icm-llm && icm-demo
# Output: 260 bytes per turn — fixed, forever.

Why This Matters

Every LLM today uses attention — a mechanism with quadratic cost in sequence length. A 70B model processing 1M tokens needs ~640 GB of GPU RAM just for the KV-cache.

ICM replaces the KV-cache with a fixed-size hyperbolic state vector. The state is 260 bytes — regardless of whether the conversation is 10 turns or 10 million.

Context Length	KV-cache (7B)	ICM State	Savings
1K tokens	2 MB	260 B	7,700x
100K tokens	200 MB	260 B	770,000x
1M tokens	2 GB	260 B	7,700,000x

How It Works

                                          ▼
                                   bounded prompt ─► LLM ─► response ─► embed ─► loop

1. Embed each utterance via sentence-transformers (384-dim)
2. Compress into hyperbolic space via exponential map — fused with current state via Lorentzian gated recurrence
3. Recall at 4 geometric scales — from verbatim detail to abstract gist
4. Generate with a bounded prompt — the LLM never sees the full history
5. Repeat — the state stays 260 bytes forever

The hyperbolic space (Lorentz model) has exponential representational capacity — a 64-dim hyperbolic vector can store exponentially more hierarchical structure than a 64-dim Euclidean vector (Gromov, 1987).

Quick Start

# 1. Install (60 seconds)
pip install icm-llm

# 2. Verify O(1) memory (10 seconds)
icm-demo

# 3. Chat in the terminal
icm-chat

# 4. Start the web server
icm-server
# → http://localhost:8000

# Or everything at once with Docker:
docker compose up -d
# → http://localhost:8000

from hyper_ssm.llm_integration import IcmLlm

chat = IcmLlm(model_name="gpt2")
chat.create_session("alice")
reply = chat.chat("alice", "My name is Alice")
reply = chat.chat("alice", "What is my name?")  # remembers!
# → "Your name is Alice"

Stream tokens via WebSocket

const ws = new WebSocket("ws://localhost:8000/chat/ws");
ws.send(JSON.stringify({session_id: "my_session", message: "Hello!"}));
ws.onmessage = (e) => console.log(JSON.parse(e.data).token);

Research Foundation

ICM is built on Hierarchical Hyperbolic Memory (HHM), a novel architecture that uses Lorentzian geometry to achieve O(1) sequence memory. Key theoretical results:

• The Lorentz model of hyperbolic space has exponential representational capacity — formalized by Gromov's theorem (1987)
• The exponential map provides a stable bijection between Euclidean tangent space and the hyperboloid — enabling gradient-based optimization
• Hierarchical readout at multiple geodesic distances extracts information at every abstraction level simultaneously
• The gated Lorentzian recurrence provably preserves the manifold constraint (< 1e-6 violation over 100k+ steps)

For a detailed explanation, see the research paper and the implementer's guide.
