# Edge/Consumer GPU Focus Implementation Plan

## Executive Summary

This plan outlines the implementation of the "Edge/Consumer GPU Focus" feature for AITBC, leveraging existing GPU marketplace infrastructure to optimize for consumer-grade hardware and enable edge computing capabilities. The feature will enhance the platform's ability to utilize geographically distributed consumer GPUs for AI/ML workloads while implementing geo-low-latency job routing and edge-optimized inference capabilities.

## Current Infrastructure Analysis

### Existing GPU Marketplace Components
Based on the current codebase, AITBC already has a foundational GPU marketplace:

**Domain Models** (`/apps/coordinator-api/src/app/domain/gpu_marketplace.py`):
- `GPURegistry`: Tracks registered GPUs with capabilities, pricing, and status
- `GPUBooking`: Manages GPU booking lifecycle 
- `GPUReview`: User feedback and reputation system

**API Endpoints** (`/apps/coordinator-api/src/app/routers/marketplace_gpu.py`):
- GPU registration and discovery
- Booking and resource allocation
- Review and reputation management

**Miner Client** (`/scripts/gpu/gpu_miner_host.py`):
- Host-based GPU miner registration
- Real-time GPU capability detection (`nvidia-smi`)
- Ollama integration for LLM inference
- Coordinator heartbeat and job fetching

**Key Capabilities Already Present**:
- GPU capability detection (model, memory, CUDA version)
- Geographic region tracking for latency optimization
- Dynamic pricing and availability status
- Ollama-based LLM inference support

## Implementation Phases

### Phase 1: Enhanced Edge GPU Discovery & Classification

#### 1.1 Consumer GPU Profile Database

class ConsumerGPUProfile(SQLModel, table=True):
    """Consumer GPU optimization profiles"""
    
    id: str = Field(default_factory=lambda: f"cgp_{uuid4().hex[:8]}", primary_key=True)
    gpu_model: str = Field(index=True)
    architecture: str = Field(default="")  # Turing, Ampere, Ada Lovelace, etc.
    consumer_grade: bool = Field(default=True)

    # Edge computing capabilities
    supports_edge_inference: bool = Field(default=True)
    supports_quantized_models: bool = Field(default=True)
    supports_mobile_deployment: bool = Field(default=False)
    
    # Geographic and network optimization
