A lightweight legal reranking and zero-shot classification/NLI model.
Overview
Kanon Universal Classifier Mini is a lightweight legal reranking and zero-shot classification/NLI model optimized for scoring the relevance of queries to legal documents and classifying legal documents. With 136 million parameters, it is 14% less accurate than the base Kanon Universal Classifier (https://aws.amazon.com/marketplace/pp/prodview-6dotzeq7aq4sy ) while being 100% smaller and faster.
Kanon Universal Classifier Mini supports a local context window of 512 tokens but can process documents of any length thanks to Isaacus' semchunk semantic chunking algorithm (https://github.com/isaacus-dev/semchunk ).
On a g6.xlarge instance, Kanon Universal Classifier Mini can rerank or classify up to 258 million tokens per hour (equivalent to roughly 64k legal documents).
Like all other Isaacus SageMaker model deployments, your Kanon Universal Classifier Mini deployment will be fully air-gapped--no data will enter or leave your AWS account.
Conveniently, Isaacus SageMaker models are also compatible with the standard Isaacus Python SDK via the Isaacus SageMaker Python integration (https://docs.isaacus.com/integrations/amazon-sagemaker ).

Dimensions summary
You pay by the host hour for running this legal reranker model on Amazon SageMaker. Pricing splits into two inference modes: batch, for processing large volumes at once, and real-time, for on-demand requests. Within each mode, you choose from ten GPU instance sizes across the ml.g5 and ml.g6 families, ranging from xlarge up to 16xlarge. Larger instances offer more compute per hour. You are charged only while an endpoint runs, so cost scales with how long and which instance you keep active.
Top-of-mind questions for buyers
You pay per host hour only while an endpoint runs. A stopped or deleted endpoint stops accruing software charges. Real-time endpoints run continuously until you delete them, so they meter time whether or not you send requests. Batch jobs meter only while processing runs.
Both meter host hours on the same instance types. Real-time mode keeps an endpoint live for on-demand requests, so it accrues time while deployed. Batch mode processes large volumes in a job and meters only during that run. Choose real-time for interactive use and batch for bulk processing.
No. This SageMaker deployment is air-gapped and runs entirely within your AWS account. You are billed per host hour through AWS Marketplace based on the instance and mode you run. There is no separate per-token API charge for these self-hosted SageMaker models.

Amazon SageMaker model
An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Deploy the model on Amazon SageMaker AI using the following options:
Version release notes
Patched release of this model with version 0.1.4 of the Isaacus SageMaker Model Server, fixing the inability to load models after 19 January 2026 due to an expired Isaacus license key that should now never expire.

Inputs
- Summary
For a user-friendly walkthrough of how to get started deploying Isaacus models on SageMaker, check out the Isaacus SageMaker quickstart guide on our docs.
This model runs on the fully air-gapped Isaacus SageMaker Model Server, which supports all the same functionality as the standard Isaacus API except that requests to the server must be proxied through the /invocations endpoint.
For example, if you wanted to send a POST request to /v1/rerankings with the data {"model":"kanon-universal-classifier-mini","query":"Who is the Governor-General?","texts":["The Governor-General is Sam Mostyn.","The King is Charles III."]}, you could so by sending /invocations the payload {"path":"/v1/rerankings","data":{"model":"kanon-universal-classifier-mini","query":"Who is the Governor-General?","texts":["The Governor-General is Sam Mostyn.","The King is Charles III."]}}.
This means that minimal code changes are necessary to switch between the online Isaacus API and your own private Isaacus model deployments.
In fact, Python users can use the Isaacus SageMaker Python integration to automatically forward requests to the Isaacus API to SageMaker deployments using the standard Isaacus SDK.
Given that this is a private deployment and that authentication is managed by AWS, Isaacus API keys are not needed and are ignored.
As a reranking and zero-shot classification model, Kanon Universal Classifier Mini currently only supports the /v1/rerankings and /v1/classifications/universal endpoints.
