 Embeddings API
 ^^^^^^^^^^^^^^
 
-Our Embeddings API is similar to ``LLM.encode``, accepting both text and :ref:`multi-modal inputs <multimodal_inputs>`.
+Our Embeddings API is similar to ``LLM.embed``, accepting both text and :ref:`multi-modal inputs <multimodal_inputs>`.
 
 The text-only API is compatible with `OpenAI Embeddings API <https://platform.openai.com/docs/api-reference/embeddings>`__
 so that you can use OpenAI client to interact with it.
