cd baguette
# Install dependencies
pip install uv && uv pip install torch torchvision safetensors transformers diffusers accelerate tqdm

The router dynamically selects different experts based on the noise level at each diffusion timestep. Early steps (high noise) often use different experts than later steps (low noise).

🚀 Future: Distributed Inference with Tailscale + Erlang
Baguette is being developed as a fully distributed inference engine that can run across multiple machines connected via Tailscale VPN, orchestrated by an Erlang/OTP supervisor.

🎯 Key Features (Planned)
| Feature | Description |
|---|---|
| Self-Organizing Network | Nodes automatically discover peers and negotiate roles |
| Adaptive Load Balancing | Routes requests based on real-time latency and compute availability |
| Auto-Benchmarking | Each node benchmarks GPU/CPU speed, VRAM, RAM, and network throughput |
| Fault Tolerance | Erlang supervisors restart failed nodes, redistribute load |
| 1 Expert Per Node | Each node loads only 1 expert (~2.7GB VRAM) plus router & VAE |
| Latency-Aware Routing | Prioritizes low-latency nodes for time-sensitive steps |
| Zero Configuration | Just join the Tailscale network and run—automatic peer discovery |
📊 Node Self-Benchmarking
When a node joins the network, it automatically benchmarks:

│ CPU: AMD Ryzen 9 7950X │
│ RAM: 64 GB │
│ CPU Compute: 2.1 TFLOPS │
│ ──────────────────────────────────── │
│ Network Latency to Peers: │

🔄 Distributed Inference Flow
- Request arrives at any node
- Router runs locally → selects top-K experts needed
- Coordinator dispatches expert calls to appropriate nodes
- Nodes compute in parallel → return velocity predictions
- Results aggregated → Euler step applied
- VAE decodes locally → image returned to requester
This enables running the full 5B parameter model across consumer hardware—each machine only needs ~4GB VRAM to hold one expert.
