LLM Classifier

The LLM (Large Language Model) Classifier is an application designed to improve data classification using advanced natural language processing techniques. It is a separate service that is attached to Sombra. Customers self-hosting Sombra can run LLM Classifier in same private network as Sombra.

The LLM Classifier container runs a gunicorn server to listen to requests and perform LLM classification on the inputs provided in the request body. As the LLM runs a mathematically computationally expensive operation, the container must run on a node with NVIDIA GPU such as the T4.

The LLM Classifier container by default listen on port 6081. This can be changed using LLM_SERVER_PORT environment variable.

To enable HTTPS connection to the LLM Classifier server you can mount the SSL cert and key file to the container and set the path to these files using environment variables LLM_CERT_PATH and LLM_KEY_PATH respectively.

You can pull our image from Transcend's private Docker registry using basic authentication.

First, please contact us and request permission to pull the llm-classifier image. We will then add your Transcend account to our permissions list.

Once we have added you to our allow list, you can log in to our private registry:

docker login docker.transcend.io

You will be prompted to enter the basic auth credentials. The username will always be "Transcend" (this is case-sensitive), and the password will be any API Key for your organization within the Admin Dashboard (note: a scope is not required for the API key).

Once you've logged in, you may pull images by running:

docker pull docker.transcend.io/llm-classifier:<version_tag>

You can deploy the LLM Classifier alongside Sombra in the same private network and configure your network to allow Sombra to reach the Classifier.

You can follow our Helm chart guide to deploy LLM Classifier along with Sombra in a Kubernets cluster or use following sample config to deploy the LLM Classifier in a Kubernetes cluster.

Update the LLM_CLASSIFIER_URL environment variable in your Sombra deployment to point to the llm-classifier-ingress created above: LLM_CLASSIFIER_URL=http://<llm-classifier-service-cluster-ip>:<llm_service_port>

We recommend using a node with a NVIDIA T4 GPU, such as AWS’s g4dn.2xlarge instance. With the LLM Classifier running on 2 g4dn.2xlarge nodes, you can get about 18,000 classifications per hour. On-demand pricing per node is $0.752 per hour (and 3-yr reserved is $0.300) as of May 21, 2024. If you need more throughput (more classifications per hour), you can add more instances of the LLM Classifier to linearly scale the throughput.
