|
| 21 |
- **Platform**: HuggingFace Spaces (Docker SDK with GPU)
|
| 22 |
- **Space ID**: `AIBRUH/eden-os`
|
| 23 |
-
- **Live URL**: `https://huggingface.co/spaces/AIBRUH/eden-os`
|
| 24 |
- **SDK**: Docker (not Gradio — we need full control over the server)
|
| 25 |
- **Hardware**: T4 GPU (free tier to start, upgrade to A10G/A100 for production)
|
| 26 |
- **Secrets**: `ANTHROPIC_API_KEY`, `HF_TOKEN` stored as HF Space secrets

When you click the link, you see the **EDEN Studio admin panel** — EVE is displayed, idle-animating (blinking, breathing), ready to converse. The full admin panel UI loads: behavioral sliders, knowledge injection modal, pipeline controls. Click "Initiate Conversation" and EVE is live.

Every feature in EDEN OS is accessible through the API. The built-in EDEN Studio frontend is just one client. A developer should be able to `curl` the API and get a talking avatar response. This is what makes it an OS, not an app.

### Existing AIBRUH Spaces Integration
|
| 132 |
-
Your existing HuggingFace Spaces become specialized microservices that EDEN OS can call:
|
| 133 |
-
- `AIBRUH/eve-voice-engine` → Voice engine can delegate to this for advanced TTS
|
| 134 |
-
- `AIBRUH/eden-realism-engine` → Genesis can call this for Eden Protocol validation
|
| 135 |
-
- `AIBRUH/eden-diffusion-studio` → Genesis can call this for FLUX portrait generation
|
| 136 |
-
- `AIBRUH/eden-comfyui-pipeline` → Animator can call this for advanced ComfyUI workflows
|
| 137 |
-
- `AIBRUH/eden-video-studio` → Conductor can delegate cinematic renders here
|
| 138 |
-
|
| 139 |
-
The core `AIBRUH/eden-os` Space is the brain that orchestrates everything. The other Spaces become optional accelerators.
|
| 140 |
-
|
| 141 |
-
### Phase One deliverable:
|
| 142 |
-
1. `AIBRUH/eden-os` Space is live on HuggingFace
|
| 143 |
-
2. Clicking the URL opens EDEN Studio with EVE ready to converse
|
| 144 |
-
3. The API is accessible at `https://AIBRUH-eden-os.hf.space/api/v1/`
|
| 145 |
-
4. Any developer can integrate EDEN OS into their own frontend via the API
|
| 146 |

## ARCHITECTURAL PHILOSOPHY: THE EDEN PROTOCOL
|
| 150 |
|
| 151 |
### The 0.3 Deviation Rule
|
| 152 |
-
Every generated frame must pass the **Eden Protocol Validator**: skin texture deviation from the reference portrait must remain below 0.3 standard deviations. This eliminates the "plastic skin" and "waxy sheen" artifacts that plague competing systems, especially on melanin-rich skin tones.
|
| 153 |
|
| 154 |
### The Three States of Presence
|
| 155 |
-
|
| 156 |
-
|
| 157 |
-
|
| 158 |
-
2. **THINKING** — The LLM generates a response. First tokens trigger TTS immediately (streaming response). The avatar transitions from listening to a "processing" micro-expression (slight brow raise, inhale).
|
| 159 |
-
3. **SPEAKING** — The 4D diffusion/animation model generates video frames synchronized with the TTS audio stream. Frame-by-frame autoregressive generation with KV-cache for temporal consistency.
|
| 160 |
|
| 161 |
### The KV-Recache Interruption Protocol
|
| 162 |
-
When a user interrupts mid-response, the system must:
|
| 163 |
- Immediately halt TTS generation
|
| 164 |
-
- Refresh
|
| 165 |
-
- Transition
|
| 166 |
-
- Begin processing
|
| 167 |
-
|
| 168 |
-
This is adapted from the LONGLIVE framework (arXiv:2509.22622) and is what separates EDEN from every "talking head" on the market.

## EDEN STUDIO ADMIN PANEL SPECIFICATION
|
| 173 |
-
|
| 174 |
-
The admin panel is the operator's control surface for EDEN OS. It has two views derived from the prototype UI: the **Main Control Surface** and the **Knowledge Injection Modal**. Every element maps to a real backend function.
|
| 175 |
-
|
| 176 |
-
### Main Control Surface (Admin Panel 1)
|
| 177 |
-
|
| 178 |
-
**Layout**: Three-column design on black (#080503) background. Left column: Settings + Backend. Center column: Pipeline controls + Connectivity. Right column: EVE avatar + context editor.
|
| 179 |
-
|
| 180 |
-
**Left Column — Behavioral Sliders**:
|
| 181 |
-
These sliders control LivePortrait's retargeting parameters and the Voice/Brain engines in real-time:
|
| 182 |
-
|
| 183 |
-
| Slider | Default | Maps To | Engine |
|
| 184 |
-
|--------|---------|---------|--------|
|
| 185 |
-
| **Consistency** | ~70% | Eden Protocol threshold. 100% = strict 0.3 deviation. Lower = relaxed matching | Genesis → `eden_protocol_validator.py` |
|
| 186 |
-
| **Latency** | 100% | Pipeline priority. 100% = max speed (Schnell, Kokoro, skip upscale). 0% = max quality (FLUX Pro, StyleTTS2, full upscale) | Conductor → `latency_enforcer.py` |
|
| 187 |
-
| **Expressiveness** | ~60% | LivePortrait retargeting amplitude. High = wide mouth, big brow raises. Low = subtle, reserved | Animator → `liveportrait_driver.py` expression_scale |
|
| 188 |
-
| **Voice Tone** | 85% | TTS pitch and warmth. High = warmer, richer. Low = neutral, clinical | Voice → `tts_engine.py` tone_warmth |
|
| 189 |
-
| **Eye Contact** | ~50% | Gaze lock to camera. 100% = locked on user. 0% = natural wandering gaze | Animator → `liveportrait_driver.py` gaze_lock |
|
| 190 |
-
| **Flirtation** | 15% | Composite: smile intensity + brow play + head tilt frequency + voice breathiness | Animator + Voice combined |
|
| 191 |
-
|
| 192 |
-
**Left Column — Buttons**:
|
| 193 |
-
- **Backend Settings** (gold) → GPU profile selector, model swap, API keys, Redis/Celery status, memory dashboard
|
| 194 |
-
- **Design** row (8 waveform icons) → Voice profile presets. Each icon = different voice character (warm female, authoritative male, calm soothing, etc.). Click to swap TTS voice instantly
|
| 195 |
-
|
| 196 |
-
**Center Column — Pipeline Controls**:
|
| 197 |
-
- **Model to Model** → Live-swap any model mid-session without restart. Switch CosyVoice2 → StyleTTS2 or LivePortrait Path A → HunyuanVideo-Avatar Path B
|
| 198 |
-
- **New Pipeline** → Pipeline builder (React Flow node editor). Drag-and-drop model nodes to create custom inference chains. Five archetypes:
|
| 199 |
-
1. **Low-Latency Streamer**: WebRTC → Whisper-Small → BitNet-3B → Kokoro → LivePortrait
|
| 200 |
-
2. **Emotive Actor**: Sentiment-Analyzer → Emotion-LoRA-Router → StyleTTS2 → HunyuanAvatar
|
| 201 |
-
3. **Knowledge Expert RAG**: Vector-DB → Context-Injection → Claude Sonnet → CosyVoice2 → LivePortrait
|
| 202 |
-
4. **Zero-Shot Creator**: User-Image-Upload → IP-Adapter → FLUX → LivePortrait
|
| 203 |
-
5. **Director's Cut**: Human-in-the-Loop → Manual-Pose-Control → LivePortrait
|
| 204 |
-
- **Connectivity** → Real-time status: WebRTC CONNECTED/DISCONNECTED, WebSocket fallback, GPU util, active models
|
| 205 |
-
|
| 206 |
-
**Right Column — Avatar + Context**:
|
| 207 |
-
- **EVE portrait** — live animated video feed during conversation
|
| 208 |
-
- **EDEN** pill button (top-right) → Avatar identity selector. Swap between different avatar models
|
| 209 |
-
- **Custom Instructions & Context Ref** overlay → System prompt editor overlaying EVE. Markdown-supported persona instructions. Shows active context document
|
| 210 |
-
- **Apply to EVE's Memory** → Commits instructions to Brain's persona manager + persists key facts to long-term memory
|
| 211 |
-
- **Compliance Matter** badge → Visual indicator that persona is compliance-reviewed (medical/financial)
|
| 212 |
-
|
| 213 |
-
**Bottom Row — Action Buttons**:
|
| 214 |
-
- **Build Voice Agent** → Voice agent creation wizard: template → persona → voice clone → appearance → deploy
|
| 215 |
-
- **Hair & Wardrobe** → Appearance editor. Changes hair, clothing, accessories, background via FLUX inpainting with IP-Adapter identity lock (face preserved, outfit changed)
|
| 216 |
-
- **THE VOICE** (large gold bar) → Full voice config: cloning upload, emotion sliders, speed, language, preview
|
| 217 |
-
- **Initiate Conversation** (large gold bar) → Primary CTA. Boots pipeline, starts idle loop, activates ASR, enters conversation mode
|
| 218 |
-
|
| 219 |
-
### Knowledge Injection Modal (Admin Panel 2)
|
| 220 |
-
|
| 221 |
-
This modal is the **intelligence layer**. It feeds EVE domain knowledge so she can discuss specific content with authority. This is the Naoma-killer: instead of a cartoon avatar reading a sales script, EVE is a photorealistic human who has consumed your product demos, audiobooks, and research.
|
| 222 |
-
|
| 223 |
-
**Input Fields**:
|
| 224 |
-
|
| 225 |
-
1. **YouTube URL Input** (with Paste button)
|
| 226 |
-
- Paste any YouTube URL. System extracts full transcript via `yt-dlp` + Whisper, key topics with timestamps, visual descriptions of product UI via frame sampling + vision model
|
| 227 |
-
- Injected into Brain's knowledge base as structured context
|
| 228 |
-
- EVE can: "Let me walk you through what was shown at the 3:42 mark of that demo..."
|
| 229 |
-
- **Use case**: Feed product demo video → EVE becomes 24/7 sales agent who discusses every feature like a human colleague who watched the video
|
| 230 |
-
|
| 231 |
-
2. **Audiobook / Media URL Input** (with Upload button)
|
| 232 |
-
- Upload MP3/WAV/M4A or paste media URLs
|
| 233 |
-
- Full transcription via Whisper → semantic chunking → vector store embedding
|
| 234 |
-
- EVE discusses themes, references passages, answers questions about content
|
| 235 |
-
- **Use case**: Feed medical textbook audio → EVE tutors students on any concept from the book
|
| 236 |
-
|
| 237 |
-
3. **Research / Prompt URL**
|
| 238 |
-
- Paste URL to arXiv paper, PDF, web article
|
| 239 |
-
- Fetches content, extracts text, chunks and embeds in RAG store
|
| 240 |
-
- EVE discusses findings, compares methodologies, explains concepts
|
| 241 |
-
- **Use case**: Feed company whitepaper → EVE presents your research as subject-matter expert
|
| 242 |
-
|
| 243 |
-
4. **Natural Language Prompt for Prototyping** (large textarea)
|
| 244 |
-
- Free-form meta-instructions for building new agent behaviors
|
| 245 |
-
- Example: "Create a conversational agent with VASA-1 level realness inspired by the Teller and Soul papers..."
|
| 246 |
-
- Tells the Brain engine how to configure itself. Supports model/paper references
|
| 247 |
-
- **Send Prompt** button fires instruction to Conductor
|
| 248 |
-
|
| 249 |
-
5. **Analyze Media Sources** (gold bar button)
|
| 250 |
-
- Batch processes all ingested media: transcription → chunking → embedding → knowledge graph construction
|
| 251 |
-
- Shows progress and summary of extracted knowledge
|
| 252 |
-
- Once complete, EVE's Brain has the full knowledge base loaded and ready
|
| 253 |
-
|
| 254 |
-

## AGENT TEAM SPECIFICATION
|
| 270 |
-
|
| 271 |
-
This project is built by a team of **7 specialized Claude Code agents** working in parallel. Each agent owns a vertical slice of the system. Agents communicate through shared file interfaces and a central orchestration manifest.

1. Build `animator/liveportrait_driver.py` — wraps LivePortrait's inference pipeline. Accepts audio features (from Voice engine) and converts them to implicit keypoint deltas for lip retargeting. Maps phoneme sequences to mouth shapes via the lip retargeting MLP. Handles eye blink injection, gaze direction from user webcam (if available), and natural head sway
|
| 361 |
-
2. Build `animator/idle_generator.py` — generates the LISTENING state idle loop. Uses LivePortrait's retargeting modules to produce natural blinks (every 3-7 seconds, randomized), micro head movements (+/-2 degrees rotation), subtle breathing motion (chest/shoulder rise), and occasional eyebrow micro-raises. This loop runs CONTINUOUSLY when the avatar is not speaking
|
| 362 |
-
3. Build `animator/state_machine.py` — manages transitions between the three states of presence:
|
| 363 |
-
- LISTENING → THINKING: triggered by ASR endpoint detection. Avatar does a subtle inhale, slight brow raise
|
| 364 |
-
- THINKING → SPEAKING: triggered by first TTS audio chunk. Avatar opens mouth, begins lip-sync
|
| 365 |
-
- SPEAKING → LISTENING: triggered by TTS completion or user interruption. Avatar closes mouth, returns to idle loop
|
| 366 |
-
- SPEAKING → LISTENING (INTERRUPT): triggered by `interruption_handler`. Immediate halt, smooth transition back to idle within 100ms using KV-recache technique adapted from LONGLIVE

4. Build `animator/audio_to_keypoints.py` — the critical bridge between Voice and Animator. Converts audio waveform features (mel spectrogram, pitch, energy) into LivePortrait-compatible implicit keypoint deltas. This replaces the need for a "driving video" — audio becomes the driver
|
| 368 |
-
5. Build `animator/eden_temporal_anchor.py` — implements the temporal consistency system adapted from LONGLIVE's frame sink concept. Always maintains the first frame of each conversation turn as a "global anchor" so the avatar never drifts from its identity over long conversations. Prevents the "latent collapse" phenomenon where AI faces slowly lose their identity
|
| 369 |
-
|
| 370 |
-
**Critical Constraint**: The animator must NEVER produce a frozen frame. Even during model loading or state transitions, the idle loop must continue. The avatar is always alive.
|
| 371 |
-
|
| 372 |
-
**File Output**: `animator/` directory. Exports an `AnimatorEngine` class with methods: `start_idle_loop()`, `drive_from_audio()`, `transition_state()`, `get_current_frame()`, `apply_eden_anchor()`

-
**Role**: Owns the conversational intelligence — LLM integration, system prompts, memory, context management, and persona behavior.
|
| 379 |
-
**Objective**: Deliver context-aware, persona-consistent responses with sub-200ms first-token latency via streaming.
|
| 380 |
-
|
| 381 |
-
**Model Stack (Tiered)**:
|
| 382 |
-
| Model | Purpose | Provider | Latency | Cost |
|
| 383 |
-
|-------|---------|----------|---------|------|
|
| 384 |
-
| Claude Sonnet 4 | Primary reasoning (cloud) | Anthropic API | <150ms first token | $0.003/1K tokens |
|
| 385 |
-
| Qwen 3 8B (GGUF Q4) | Local fallback / offline mode | `Qwen/Qwen3-8B-GGUF` via llama.cpp | <300ms first token | $0 |
|
| 386 |
-
| BitNet b1.58 3B | Ultra-efficient edge mode | `microsoft/BitNet` via llama.cpp | <200ms first token | $0 |
|
| 387 |
-
|
| 388 |
-
**Tiered Selection**:
|
| 389 |
-
- Internet available + API key configured → Claude Sonnet 4 (best quality)
|
| 390 |
-
- Offline or API failure → Qwen 3 8B via llama.cpp (good quality, runs on CPU+GPU)
|
| 391 |
-
- Edge deployment / mobile / low-VRAM → BitNet 3B (acceptable quality, runs on CPU only, frees GPU for animation)
|
| 392 |
-
|
| 393 |
-
**Tasks**:
|
| 394 |
-
1. Build `brain/reasoning_engine.py` — LLM interface with streaming response. Must yield tokens as they arrive (not wait for complete response). Supports both Anthropic API (cloud) and llama.cpp (local). Handles system prompt injection, conversation history, and persona context
|
| 395 |
-
2. Build `brain/persona_manager.py` — loads agent persona from YAML template files. Each persona defines: name, role, tone, knowledge domain, emotional baseline, conversation boundaries. The persona shapes every response
|
| 396 |
-
3. Build `brain/memory_manager.py` — maintains conversation history within session. Implements sliding window context (last 20 turns). Extracts key facts mentioned by user for context persistence. Future: vector DB integration for long-term memory
|
| 397 |
-
4. Build `brain/streaming_bridge.py` — the critical integration point. As LLM tokens stream in, this module:
|
| 398 |
-
- Buffers tokens until a natural speech boundary (sentence end, comma pause, etc.)
|
| 399 |
-
- Sends each buffer to Voice engine for TTS generation
|
| 400 |
-
- Voice engine sends audio chunks to Animator engine for lip-sync
|
| 401 |
-
- Result: the avatar begins speaking within 500ms of the user finishing their question
|
| 402 |
-
5. Build `brain/template_loader.py` — loads and validates agent templates (YAML). Templates define the full agent configuration: persona, voice profile, visual appearance preferences, knowledge base references
|
| 403 |
-
|
| 404 |
-

## ARCHITECTURAL PHILOSOPHY: THE EDEN PROTOCOL
|
| 98 |
|
| 99 |
### The 0.3 Deviation Rule
|
| 100 |
+
Every generated frame must pass the **Eden Protocol Validator**: skin texture deviation from the reference portrait must remain below 0.3 standard deviations. This eliminates the "plastic skin" and "waxy sheen" artifacts that plague competing systems, especially on melanin-rich skin tones.
|
| 101 |
|
| 102 |
### The Three States of Presence
|
| 103 |
+
1. **LISTENING** — Avatar maintains active listening behaviors (micro-blinks, subtle nodding, gaze tracking). ASR processes audio in real-time. Avatar is NOT frozen.
|
| 104 |
+
2. **THINKING** — LLM generates response. First tokens trigger TTS immediately. Avatar transitions with subtle inhale + brow raise.
|
| 105 |
+
3. **SPEAKING** — Animation frames synchronized with TTS audio stream. Frame-by-frame with KV-cache for temporal consistency.
|
|
|
|
|
|
|
| 106 |
|
| 107 |
### The KV-Recache Interruption Protocol
|
|
|
|
| 108 |
- Immediately halt TTS generation
|
| 109 |
+
- Refresh KV-cache while preserving temporal anchors (no glitch)
|
| 110 |
+
- Transition avatar back to LISTENING within 100ms
|
| 111 |
+
- Begin processing new user input

## VERSIONED SAVE PROTOCOL
|
| 369 |
|
| 370 |
+
```bash
|
| 371 |
+
# Save to all 3 locations with version tag:
|
| 372 |
+
bash scripts/save_versioned.sh v1.1
|
| 373 |
+
|
| 374 |
+
# What it does:
|
| 375 |
+
# 1. git commit + tag v1.1
|
| 376 |
+
# 2. git push to GitHub (tyronne-os/EDEN-OS)
|
| 377 |
+
# 3. Upload to HuggingFace (AIBRUH/eden-os)
|
| 378 |
+
# 4. Copy to Seagate 5TB (S:\eden-os\versions\v1.1)
|
| 379 |
+
# 5. Update latest symlink + VERSION_LOG.md
|
| 380 |
+
# 6. Keep last 10 versions, auto-clean older

## NEXT: PHASE TWO
|
| 386 |
|
| 387 |
+
Phase Two transforms EDEN OS into the **EDEN Studio SaaS**:
|
| 388 |
+
- Multi-tenant architecture with Stripe billing
|
| 389 |
+
- EDEN Studio React frontend with gold/onyx design language
|
| 390 |
+
- Agent template marketplace
|
| 391 |
+
- White-label customization for enterprise
|
| 392 |
+
- HuggingFace Space deployment for free tier
|
| 393 |
+
- Mobile SDK for iOS/Android
|
| 394 |
+
|
| 395 |
+
But first — Phase One must be bulletproof. The engine must sing before we build the concert hall.

Tests the FULL bi-directional conversation pipeline with video output.
|
| 4 |
+
Validates that EVE is indistinguishable from a human on a video call.
|
| 5 |
+
|
| 6 |
+
Test Categories:
|
| 7 |
+
1. Live Conversation Simulation (text → brain → voice → animator → video)
|
| 8 |
+
2. Lip-Sync Phoneme Accuracy (audio energy → mouth shape correlation)
|
| 9 |
+
3. Micro-Expression Coherence (emotion in text → facial expression in frames)
|
| 10 |
+
4. Real-Time Performance Benchmarks (latency, FPS, jitter)
|
| 11 |
+
5. Multi-Turn Memory & Coherence (personality consistency across turns)
|
| 12 |
+
6. Video Quality Forensics (anti-AI-detection metrics)
|
| 13 |
+
7. Perceptual Realism Metrics (SSIM, LPIPS-proxy, temporal flicker)
|
| 14 |
+
8. Stress Tests (rapid interrupts, long conversations, emotional range)

EDEN OS -- VOCAL REALISM Test Suite
|
| 3 |
+
Validates that EVE sounds alive and natural across all voice subsystems.
|
| 4 |
+
|
| 5 |
+
Tests cover:
|
| 6 |
+
1. TTS Audio Quality
|
| 7 |
+
2. Emotion Routing
|
| 8 |
+
3. Voice Naturalness Analysis
|
| 9 |
+
4. Interruption Handling
|
| 10 |
+
5. ASR Quality
|
| 11 |
+
6. Voice Cloning
|
| 12 |
+
7. Audio-Visual Sync
|
| 13 |
+
|
| 14 |
+
All tests use synthetic audio (numpy sine waves, noise, silence) so they
|
| 15 |
+
run without model weights. The engines gracefully fall back to deterministic
|
| 16 |
+
sine-wave synthesis and energy-based VAD when heavy models are absent.
|
| 17 |
+
|
| 18 |
+
Run:
|
| 19 |
+
cd ~/EDEN-OS && source .venv/bin/activate
|
| 20 |
+
python -m pytest tests/test_vocal_realism.py -v
