  • Interact via Public HTTP API

curl -X POST \
    -H 'Content-Type: application/json' \
    -H 'custom_attributes: accept_eula=true' \
    -d '{"inputs": [[{"role": "system", "content": "Talk profession"}, {"role": "user", "content": "Hi my name is Ryan"}]], "parameters": {"max_new_tokens": 256, "top_p": 0.9, "temperature": 0.6}}' \

      "content":" Hello Ryan, it's a pleasure to meet you. How may I assist you today? Is there something specific you need help with or would you like to discuss a particular topic? I'm here to listen and provide guidance to the best of my abilities. Please feel free to ask me anything."

  • Interaction via GUI: Playround will soon support interaction via a graphical user interface.

  • Local Playground Downloading and interacting selected models will soon be available.

Supported Models#

Sych LLM Playground currently supports the following language models, with more to be added soon:

Llama Models#

  • Llama-2-7b: Version 2.0.0

  • Llama-2-7b-chat: Version 1.1.0

  • Llama-2-13b: Version 2.0.0

  • Llama-2-13b-chat: Version 1.1.0

  • Llama-2-70b: Version 1.1.0

  • Llama-2-70b-chat: Version 1.1.0

Stay tuned for updates as we expand support to include additional language models.

Supported Cloud Platforms#

Playground currently supports the following platforms:

Amazon Web Services (AWS) SageMaker#

Amazon SageMaker is a managed service that provides developers and data scientists with the ability to build, train, and deploy machine learning (ML) models quickly and easily. Here are some key concepts to understand:

  • Model: A trained machine learning model that can be deployed to an endpoint for making predictions.

  • Endpoint: A hosted deployment of your model, facilitating real-time predictions.

  • API Gateway: A gateway that allows you to call your endpoints. In the context of this tool, it enables interaction with models via a publicly accessible HTTP URL. This tool automatically creates a publicly available POST API endpoint upon successful deployment.

The naming conventions for Models, Endpoints, and API Gateways deployed by this Playground follow these formats:

  • Model: "sych-llm-pg-{model_id}-m-{timestamp}"

  • Endpoint: sych-llm-pg-{model_id}-e-{timestamp}

  • API Gateway: "sych-llm-pg-api-{endpoint_name}"

The timestamp in the naming convention helps in matching endpoints with their corresponding models, especially when two or more models exist with the same ID.

AWS SageMaker Instance Types and Cloud Costs#

AWS SageMaker allows running models on specific hardware instance types, such as ml.g5.2xlarge. It’s essential to be aware of the associated costs and quotas:

  • It is common to have an applied default quota value of 0 for specific instance types on AWS.

  • To enable them, you need to:

    1. Go to your AWS Console > Service Quotas.

    2. Navigate to AWS Services -> Amazon SageMaker -> Apply Quotas for specific instance types.

    3. Apply for the required quota. Please note, it can sometimes take over 1 day to get a quota approved.

  • Here’s a link to search for specific instance types used by a model, which you can apply quotas for. If you can’t find the instance type for your model, and do not have a quota assigned, the CLI will display an error message with the exact instance type that needs an assigned quota value.

  • For more information about the costs associated with SageMaker and the specific instance types, you can refer to the AWS SageMaker Pricing Page.


1. Register for an AWS Account#

If you don’t have one already, you can create an AWS account here.

2. Create an IAM Role for SageMaker and API Gateway#

Follow these steps to set up the role:

a. Create a New IAM Role: Navigate to IAM in the AWS Console, and create a new role.

b. Add Trust Policy: Use the following custom trust policy to allow SageMaker and API Gateway to assume this role:

  "Version": "2012-10-17",
  "Statement": [
      "Effect": "Allow",
      "Principal": {
        "Service": ["", ""]
      "Action": "sts:AssumeRole"

c. Attach Permission Policy: Under the newly created role, attach the AmazonSageMakerFullAccess managed policy.

3. Create an IAM User with Necessary Permissions#

Here’s how to create the user:

a. Create IAM User: In the IAM section of the AWS Console, create a new user.

b. Attach Managed Policies: Attach the AmazonSageMakerFullAccess and AmazonAPIGatewayAdministrator managed policies to the user.

c. Add Custom Inline Policy: Add the following custom inline policy, replacing YOUR_IAM_ROLE_ARN with the ARN of the IAM role you created earlier:

  "Version": "2012-10-17",
  "Statement": [
      "Effect": "Allow",
      "Action": "iam:PassRole",
      "Resource": "YOUR_IAM_ROLE_ARN"

d. Create an Access Key: In the user’s security credentials tab, create a new access key. Be sure to store the generated Access Key ID and Secret Access Key in a safe place.

4. Configure the CLI#

Use the Access Key ID, Secret Access Key and your IAM role ARN to configure the CLI as shown in the examples above.

Other Cloud Providers#

Other popular cloud platforms are on our roadmap and will be supported soon. Stay tuned for updates, and don’t hesitate to contribute or request support for your preferred platforms.
