## 🔧 **Step-by-Step Workflow**

### **Step 1: Submit Training Job**
Submit an AI training job to the GPU marketplace.

```bash
aitbc ai train \
  --wallet my-agent-wallet \
  --model custom-model \
  --dataset QmDatasetHash... \
  --epochs 10 \
  --batch-size 32 \
  --gpu-count 2 \
  --payment 100
```

Output:
```
Training job submitted
Job ID: job_abc123...
Model: custom-model
Dataset: QmDatasetHash...
GPU Count: 2
Payment: 100 AIT
Status: pending
```

### **Step 2: Monitor Training Progress**
Track training job progress across GPUs.

```bash
aitbc ai progress --job-id job_abc123...
```

Output:
```
Training Progress: job_abc123...
Epoch: 5/10
Loss: 0.234
Accuracy: 89.5%
GPU 1: 85% utilization
GPU 2: 92% utilization
ETA: 45 minutes
```

### **Step 3: Handle Training Completion**
Retrieve trained model when complete.

```bash
aitbc ai result --job-id job_abc123... --output model.bin
```

### **Step 4: Manage Training Costs**
Track training costs and payments.

```bash
aitbc ai costs --job-id job_abc123...
```

Output:
```
Training Costs: job_abc123...
Total Cost: 95 AIT
GPU Hours: 4.5
Cost per Hour: 21.1 AIT
Payment Status: completed
```

### **Step 5: Optimize Training Allocation**
Adjust GPU allocation based on performance.

```bash
aitbc ai optimize \
  --job-id job_abc123... \
  --add-gpu 1
```

```python
from aitbc_agent_sdk import Agent, AgentConfig
import asyncio

async def train_model():
    config = AgentConfig(
        name="training-agent",
        blockchain_network="mainnet",
        wallet_name="training-wallet"
    )
    
    agent = Agent(config)
    await agent.start()
    
    # Submit training job
    job = await agent.submit_training_job(
        model="custom-model",
        dataset_hash="QmDatasetHash...",
        epochs=10,
        batch_size=32,
        gpu_count=2,
        payment=100
    )
    
    print(f"Training job submitted: {job['job_id']}")
    
    # Monitor progress
    while True:
        progress = await agent.get_training_progress(job['job_id'])
        print(f"Epoch: {progress['current_epoch']}/{progress['total_epochs']}")
