+---
+
+DeepSeek is an AI lab that has developed and released a series of open source
+LLMs that are notable for both their performance and cost-efficiency. By using a
+Mixture-of-Experts (MoE) system that utilizes only 37 billion of the models' 671
+billion parameters for any task, the DeepSeek-R1 model is able to achieve best
+in class performance at a fraction of cost of inference on other comparable
+models. In this guide we review how to leverage the DeepSeek models using Modus.
+
+## Options for using DeepSeek with Modus
+
+There are two options for invoking DeepSeek models in your Modus app:
+
+1. [Use the distilled DeepSeek model hosted by Hypermode](#using-the-distilled-deepseek-model-hosted-by-Hypermode)
+   Hypermode hosts and makes available the distilled DeepSeek model which can be
+   used by Modus apps developed locally and deployed to Hypermode
+2. [Use the DeepSeek API with your Modus app](#using-the-deepseek-api-with-modus)
+   Access DeepSeek models hosted on the DeepSeek platform by configuring a
+   DeepSeek connection in your Modus app and using your DeepSeek API key
