+
+            With a GPU, a query takes from a few seconds to a few tens of seconds, dependent on the number of words/characters
+            the question and responses contain. The quality of the responses varies quite a bit it seems. Even the same
+            question with the same parameters, asked at different times, can result in quite different responses.
+
+            * Low temperature: responses will be more deterministic and focused; High temperature: responses more creative.
+
+            * Suggested temperatures -- translation: up to 0.3; chatting: > 0.4
+
+            * Top P controls dynamic vocabulary selection based on context.
+
+            For a table of example values for different scenarios, refer to [this](https://community.openai.com/t/cheat-sheet-mastering-temperature-and-top-p-in-chatgpt-api-a-few-tips-and-tricks-on-controlling-the-creativity-deterministic-output-of-prompt-responses/172683)
+
+            If the instance is not on a GPU (T4), it will be very slow. You can try to run the colab notebook [chatglm2-6b-4bit colab notebook](https://colab.research.google.com/drive/1WkF7kOjVCcBBatDHjaGkuJHnPdMWNtbW?usp=sharing) for a spin.
