Once you select a project, you'll enter its specific dashboard. Here, manage everything from data uploads to training job configurations. Start by uploading your datasets, which should include paired examples of input texts and their expected outputs in a supported format (CSV).

You can upload your datasets under the Datasets section. All you need to do is provide your data with input and expected output. That's it!!

4: Creating and Managing Training Jobs

To start a new training job or monitor existing ones, head to the 'Training Jobs' section. Here you can see all your experiments and their statuses—whether they're pending, running, or completed.

5: Setting Up a New Training Job for Llama 3

When creating a new training job, you'll specify the job's name and choose Llama3 from several available options. This step is pivotal as it sets the foundation for your model's learning process.

6: Configuring Hyperparameters (Optional)

Adjusting hyperparameters can drastically affect your model’s learning efficiency and outcome. For instance, a lower learning rate might slow down the training but can lead to more precise adjustments in the model’s weights, potentially resulting in a higher-quality model. While we have set the default hyperparameters using optimized values, you can still play around with settings like learning rate, batch size, and the number of training epochs to further optimize your model's training. If unsure, it's safe to use the parameters as they are initially set.

7: Customizing the Training Script (Optional)

For advanced users, the platform allows editing the training script directly. This feature is designed to provide flexibility in implementing custom learning algorithms or adaptations. If you are unsure about making changes, it's recommended not to alter the script to avoid unintended consequences.

8:Training Execution and Monitoring

Once your training job is configured and initiated, the platform automatically allocates the appropriate resources, such as an EC2 instance with GPU support, based on the selected model size and parameters. You can monitor the progress directly within the 'Training Jobs' section, viewing logs and performance metrics in real-time.

Deploying Your Trained Model (Complementary Feature)

Once your model has been fine-tuned and trained, you can easily deploy it directly from the platform. This seamless transition from training to deployment facilitates a quick turnaround for integrating AI capabilities into your applications.

In the 'Fine-Tuned Models' section, you can view all the trained model artifacts. For each model, you have the option to download the model for offline use or deploy it with just a simple click!!

Once clicked, the platform packages your model into a deployable container, which is then hosted on a cloud server, providing you with an API endpoint for easy access and integration. This feature is designed to simplify the way you bring your AI models into production environments.

Testing Your Model

Before full deployment, you might want to test how your model performs with real data. Our platform includes a testing playground where you can input text and see how the model responds in real-time.

Interactive Model Testing

The testing playground is an invaluable tool for immediate, hands-on testing. Simply enter your text and let the model generate outputs. This is perfect for fine-tuning output styles, testing different inputs for consistency, or demonstrating the model’s capabilities in a controlled environment.

Integrating with Your Systems

After testing and deploying your model, the next step is integration. The platform provides an API which you can use to connect the deployed model with your applications.

Demo API Request

The final screenshot shows how to make a demo API request. This section provides you with the necessary API endpoints, request formats, and authentication methods to help you integrate the model's capabilities into your existing systems seamlessly.
