HIP-0002: Hamiltonian Large Language Models (HLLMs) Specification

Abstract

This proposal defines the architecture, capabilities, and standards for Hamiltonian Large Language Models (HLLMs). HLLMs are multimodal AI models with per-user fine-tuning, where every user owns their personalized model fork. These models support text, vision, audio, and 3D modalities with unified representations and cross-modal understanding.

Specification

Model Architecture

Unified Transformer Architecture with Hamiltonian Dynamics

class HLLMArchitecture:
    modalities = ["text", "vision", "audio", "3d"]
    hidden_dim = 4096  # Base model
    num_layers = 48
    num_heads = 64
    context_length = 32768
    
    # Modality-specific encoders
    text_encoder: "Byte-level BPE"
    vision_encoder: "Vision Transformer patches"
    audio_encoder: "Mel-spectrogram transformer"
    3d_encoder: "Point cloud transformer"
    
    # Unified decoder
    decoder: "Autoregressive transformer"

Model Variants

Model	Parameters	Context	Modalities	Use Case
HLLM-7B	7B	8K	Text, Vision	Edge deployment, personal devices
HLLM-32B	32B	32K	Text, Vision, Audio	Standard per-user models
HLLM-175B	175B	128K	All	Advanced personal assistants
HLLM-1T	1T	256K	All + specialized	Research & collective intelligence

Note: These are BASE models only. Every user interaction creates a personalized fork with user-specific LoRA adapters, making each user's model unique.

Capabilities

Core Capabilities

Cross-modal Understanding: Understand relationships between modalities
Any-to-Any Generation: Generate any modality from any input
Zero-shot Transfer: Apply learning across modalities
Compositional Reasoning: Combine modalities for complex reasoning

Specific Tasks

Vision-Language: Image captioning, VQA, visual reasoning
Audio-Language: Speech recognition, audio description
3D-Language: 3D scene understanding, spatial reasoning
Multimodal Generation: Create images from text+audio, etc.

Training Infrastructure

Base Model Training

Text: 10T tokens from web, books, code
Images: 5B image-text pairs
Audio: 100K hours of audio with transcripts
3D: 10M 3D scenes with annotations
Synthetic: Generated multimodal data for alignment

Per-User Fine-Tuning (Automatic)

Data: User's own interactions (encrypted)
Compute: ~35ms per interaction for gradient update
Storage: ~100MB per user for LoRA adapters
Privacy: All training data stays encrypted with user's key
Ledger: Every training operation recorded on-chain

Key Difference: Base models are trained once. Per-user models continuously evolve with every interaction, creating billions of unique models.

Inference Optimization

Techniques

Modality Routing: Process only relevant modalities
Sparse Attention: Reduce computation for long contexts
Quantization: INT8/INT4 for edge deployment
Caching: KV-cache across modalities
Batching: Dynamic batching for different modalities

Performance Targets

Latency: <100ms for first token (HLLM-32B)
Throughput: >1000 tokens/second (batched)
Memory: <16GB for HLLM-7B inference

Safety and Alignment

Safety Measures

Content Filtering: Multi-modal content moderation
Watermarking: Invisible watermarks in generated content
Attribution: Track training data influence
Bias Mitigation: Cross-modal debiasing techniques

Alignment Techniques

RLHF: Reinforcement Learning from Human Feedback
Constitutional AI: Rule-based constraints
Multimodal Alignment: Cross-modal consistency checks
