 The **onnxruntime** API is available from `globalThis` and shares similar specs of [onnxruntime-common](https://github.com/microsoft/onnxruntime/tree/main/js/common).
 
 The available items are:
 
-- `Tensor`: represent a basic tensor with specified dimensions and data type. -- "The AI input/output"
-- `InferenceSession`: represent the inner model session. -- "The AI model itself"

+## The `Session` class
 
-onnxruntime:
+Prior versions has [introduced](https://supabase.com/blog/ai-inference-now-available-in-supabase-edge-functions) the `Session` class as alternative to `transformers.js` for *gte-small* model and then was used to provide a [LLM interface](https://supabase.com/docs/guides/functions/ai-models?queryGroups=platform&platform=ollama#using-large-language-models-llm) for Ollama and some other providers.
 
-the Session class:
+Since the **Model Execution Engine** was created the `Session` class now can focus on LLM interface while the `Session('gte-small')` is for compatibility purposes only.

+> [!WARNING]
+> Docs for Session class will end here - There's a open [PR #539](https://github.com/supabase/edge-runtime/pull/539) that may change a lot of things for it.
