+    Reference: https://github.com/petals-infra/chat.petals.dev#post-apiv1generate
+    The `PetalsConfig` class encapsulates the configuration for the Petals API. The properties of this class are described below:
+
+    - `max_length` (integer): This represents the maximum length of the generated text (including the prefix) in tokens.
+
+    - `max_new_tokens` (integer): This represents the maximum number of newly generated tokens (excluding the prefix).
+
+    The generation parameters are compatible with `.generate()` from Hugging Face's Transformers library:
+
+    - `do_sample` (boolean, optional): If set to 0 (default), the API runs greedy generation. If set to 1, the API performs sampling using the parameters below:
+
+    - `temperature` (float, optional): This value sets the temperature for sampling.
+
+    - `top_k` (integer, optional): This value sets the limit for top-k sampling.
+
+    - `top_p` (float, optional): This value sets the limit for top-p (nucleus) sampling.
+
+    - `repetition_penalty` (float, optional): This helps apply the repetition penalty during text generation, as discussed in this paper.
