+    Reference: https://docs.cohere.com/reference/generate
+
+    The class `CohereConfig` provides configuration for the Cohere's API interface. Below are the parameters:
+
+    - `num_generations` (integer): Maximum number of generations returned. Default is 1, with a minimum value of 1 and a maximum value of 5.
+
+    - `max_tokens` (integer): Maximum number of tokens the model will generate as part of the response. Default value is 20.
+
+    - `truncate` (string): Specifies how the API handles inputs longer than maximum token length. Options include NONE, START, END. Default is END.
+
+    - `temperature` (number): A non-negative float controlling the randomness in generation. Lower temperatures result in less random generations. Default is 0.75.
+
+    - `preset` (string): Identifier of a custom preset, a combination of parameters such as prompt, temperature etc.
+
+    - `end_sequences` (array of strings): The generated text gets cut at the beginning of the earliest occurrence of an end sequence, which will be excluded from the text.
+
+    - `stop_sequences` (array of strings): The generated text gets cut at the end of the earliest occurrence of a stop sequence, which will be included in the text.
+
+    - `k` (integer): Limits generation at each step to top `k` most likely tokens. Default is 0.
+
+    - `p` (number): Limits generation at each step to most likely tokens with total probability mass of `p`. Default is 0.
+
+    - `frequency_penalty` (number): Reduces repetitiveness of generated tokens. Higher values apply stronger penalties to previously occurred tokens.
+
+    - `presence_penalty` (number): Reduces repetitiveness of generated tokens. Similar to frequency_penalty, but this penalty applies equally to all tokens that have already appeared.
+
+    - `return_likelihoods` (string): Specifies how and if token likelihoods are returned with the response. Options include GENERATION, ALL and NONE.
+
+    - `logit_bias` (object): Used to prevent the model from generating unwanted tokens or to incentivize it to include desired tokens. e.g. {"hello_world": 1233}
