Tantra-LLM v0.6-fusion_wiring

Proprietary Multimodal Cognitive Architecture

A complete rewrite transforming into a proprietary brain system using SpikingBrain-7B + Long-VITA + Whisper with dynamic context, fusion layers, hybrid memory, and adaptive personality.

🧠 Architecture Overview

Core Components

• SpikingBrain-7B: Reasoning core
• Long-VITA/EVA-ViT: Vision encoder
• Whisper Large-v3: Audio encoder
• Coqui TTS: Speech generation
• Proprietary Fusion Layers: Vision+audio → language alignment (~5M params)
• Hybrid Memory: Working memory + episodic vector + semantic graph
• Adaptive Personality: Mode-aware behavior with user overrides

🚀 Quick Start

One-Click Start (Windows)

scripts\start_api.bat

Server starts on http://localhost:8000.

Manual Start

# Activate venv
.\.venv\Scripts\Activate.ps1

# Set env
$env:PYTHONPATH="D:\Atulya\Tantra-LLM"
$env:TANTRA_LV_DIR="D:\models\longvita-16k"  # Optional: Long-VITA path
$env:TANTRA_SPB="microsoft/DialoGPT-medium"   # Your model name

# Start API
uvicorn demos.api_server:app --host 0.0.0.0 --port 8000

Python API Usage

import requests

# Text-only
response = requests.post("http://localhost:8000/generate", files={"text": "Hello"})
print(response.json())

# With image
with open("image.jpg", "rb") as f:
    response = requests.post("http://localhost:8000/generate", 
        files={"text": "Describe this", "image": f})

Model Status

Model	Status	Notes
SpikingBrain-7B	✅ Working	Use TANTRA_SPB to set HF model ID
Long-VITA-16K	⚠️ Partial	Vision embeddings path wired, full forward pending
Whisper	✅ Installed	Ready for audio encoding
Coqui TTS	❌ Skipped	Requires MSVC build tools

🎯 Key Features

Completed (v0.1–v1.0)

• v0.1: System identity
• v0.2: Dynamic context + flattened structure
• v0.3: Episodic memory influence
• v0.4: Semantic graph influence
• v0.5: Adaptive personality routing
• v0.6: Fusion gates + projector shape validation
• v0.7: Real encoder integration
• v0.8: SpikingBrain forward pass with embeddings injection
• v1.0: Complete production system with one-click start

Future Enhancements

• Long-VITA full local forward (requires GPU)
• Coqui TTS when MSVC tools available
• Advanced KV-cache and streaming optimizations
• Database backends (ChromaDB/FAISS/Neo4j)

🔬 Design Philosophy

Proprietary Assets

1. Fusion projection weights (~5M params) - Owned, trainable, small
2. Adapter parameters - Personality/style injection
3. Memory routing logic - Control loop decisions
4. Identity configuration - Behavioral rules
5. Training prompts - Fusion layer curricula

All stored separately from base models, easily versioned and protected.
