Model Training

Ultralytics Platform provides comprehensive tools for training YOLO models, from organizing experiments to running cloud training jobs with real-time metrics streaming.

Watch: Get Started with Ultralytics Platform - Train

Overview

The Training section helps you:

• Organize models into projects for easier management
• Train on cloud GPUs with a single click
• Monitor real-time metrics during training
• Compare model performance across experiments
• Export to 17+ deployment formats (see supported formats)

Stage	Description
Project	Create a workspace to organize related models
Configure	Select dataset, base model, and training parameters
Train	Run on cloud GPUs or your local hardware
Monitor	View real-time loss curves and metrics
Export	Convert to 17+ deployment formats (details)

Training Options

Ultralytics Platform supports multiple training approaches:

Method	Description	Best For
Cloud Training	Train on Ultralytics Cloud GPUs	No local GPU, scalability
Local Training	Train locally, stream metrics to the platform	Existing hardware, privacy
Colab Training	Use Google Colab with platform integration	Free GPU access

GPU Options

Available GPUs for cloud training on Ultralytics Cloud:

{% include "macros/platform-gpu-table.md" %}

!!! info "GPU Tier Access"

H200 and B200 GPUs require a [Pro or Enterprise plan](../account/billing.md#plans). All other GPUs are available on all plans including Free.

!!! tip "Signup Credits"

New accounts receive signup credits for training. Check [Billing](../account/billing.md) for details.

Real-Time Metrics

During training, view live metrics across three subtabs:

    A --> C[Performance Metrics]
    D[Console] --> E[Live Logs]
    D --> F[Error Detection]
    G[System] --> H[GPU Utilization]
    G --> I[Memory & Temp]

    style A fill:#2196F3,color:#fff
    style D fill:#FF9800,color:#fff
    style G fill:#9C27B0,color:#fff

Subtab	Metrics
Charts	Box/class/DFL loss, mAP50, mAP50-95, precision, recall
Console	Live training logs with ANSI color and error detection
System	GPU utilization, memory, temperature, CPU, disk

!!! info "Automatic Checkpoints"

For cloud training, the **best model** (`best.pt`, the highest-mAP checkpoint) is saved automatically and made available for download, export, and deployment after training completes.

Quick Start

Get started with cloud training in under a minute:

=== "Cloud (UI)"

1. Create a project in the sidebar
2. Click **New Model**
3. Select a model, dataset, and GPU
4. Click **Start Training**

=== "Remote (CLI)"

```bash
export ULTRALYTICS_API_KEY="YOUR_API_KEY"
yolo train model=yolo26n.pt data=ul://username/datasets/my-dataset \
  epochs=100 project=username/my-project name=exp1
```

=== "Remote (Python)"

```python
from ultralytics import YOLO

model = YOLO("yolo26n.pt")
model.train(
    data="ul://username/datasets/my-dataset",
    epochs=100,
    project="username/my-project",
    name="exp1",
)
```

FAQ

How long does training take?

Training time depends on:

• Dataset size (number of images)
• Model size (n, s, m, l, x)
• Number of epochs
• GPU type selected

A typical training run with 1000 images, YOLO26n, 100 epochs on RTX PRO 6000 takes about 2-3 hours. Smaller runs (500 images, 50 epochs on RTX 4090) complete in under an hour. See cost examples for detailed estimates.

Can I train multiple models simultaneously?

Yes. Concurrent cloud training limits depend on your plan: Free allows 3, Pro allows 10, and Enterprise is unlimited. For additional parallel training, use remote training from multiple machines.

What happens if training fails?

If training fails:

1. Checkpoints are saved at each epoch
2. You can resume from the last checkpoint
3. Credits are only charged for completed compute time

How do I choose the right GPU?

Scenario	Recommended GPU
Most training jobs	RTX PRO 6000
Large datasets or batch sizes	H100 SXM or H200 (Pro+)
Budget-conscious	RTX 4090
