Quick Start (30 seconds)

# 1. Start services
docker compose up -d

# 2. Check health
curl http://localhost:8003/health

# 3. List models
curl http://localhost:8003/api/models

# 4. Run inference
curl -X POST http://localhost:8003/api/inference/chat \
  -H "Content-Type: application/json" \
  -d '{"message":"Hello!","temperature":0.7,"max_tokens":2048,"system_prompt":"Help"}'

# 5. Run tests
python test_user_functions.py

Deployment Instructions

Docker

cd ~/mohawk-inference-engine
docker compose up -d

Kubernetes (Ready to deploy)

kubectl apply -f k8s-manifest.yaml

Native Python (Development)

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python -m uvicorn prototype.gui_backend:app --port 8003

Known Limitations (Minor)

  1. Inference Responses: Currently simulated. Real LLM integration needed.
  2. Metrics: Randomly generated. Connect to actual system metrics (psutil).
  3. Persistence: In-memory storage. Add Redis/PostgreSQL for production.
  4. Authentication: JWT framework ready; implement secret management.
  5. Service Discovery: Works on LAN; limited in isolated Docker networks.

Recommendations for Production

Phase 1 (Immediate)

  • Integrate real LLM models (Llama, Mistral, etc.)
  • Connect to system metrics (psutil, GPU monitoring)
  • Add Redis for session persistence
  • Implement proper JWT secret management

Phase 2 (Short-term)

  • Add PostgreSQL for historical metrics
  • Implement user authentication
  • Build Prometheus/Grafana monitoring
  • Add request rate limiting

Phase 3 (Medium-term)

  • Deploy to Kubernetes
  • Add horizontal scaling
  • Implement model serving (vLLM, TensorRT)
  • Build web UI dashboard

Phase 4 (Long-term)

  • Multi-cloud support
  • Advanced RAG capabilities
  • Fine-tuning pipeline
  • Analytics & reporting
