+
+        Args:
+            conversation (Union[List[Dict[str, str]], "Conversation"]): A Conversation object or list of dicts

+            tools (List[Dict]): a list of tools to render into the prompt for the model to choose from.
+                See an example at the bottom of the docstring.
+                The format should be:
+                   * name (str): The name of the tool to be called. Valid names contain only the characters a-z,
+                        A-Z, 0-9, _ and must not begin with a digit.
+                   * description (str): The description of what the tool does, the model uses the description to 
+                        choose when and how to call the function.
+                   * parameter_definitions (List[Dict]): The input parameters of the tool. Accepts a dictionary 
+                        where the key is the name of the parameter and the value is the parameter spec.
+                        Valid parameter names contain only the characters a-z, A-Z, 0-9, _ and must not begin with a digit. 
+                        Parameter specs are as follows:
+                       * description (str): The description of the parameter.
+                       * type (str): the type of the parameter - most effective for python builtin data types, such as 'str', 'bool'
+                       * required: boolean: Denotes whether the parameter is always present (required) or not. Defaults to not required.
+            tool_use_template (str, *optional*): A Jinja template to use for this conversion. If
+                this is not passed, the model's default chat template will be used instead.
+            add_generation_prompt (bool, *optional*): Whether to end the prompt with the token(s) that indicate
+                the start of an assistant message. This is useful when you want to generate a response from the model.
+                Note that this argument will be passed to the chat template, and so it must be supported in the
+                template for this argument to have any effect.
+            tokenize (`bool`, defaults to `True`):
+                Whether to tokenize the output. If `False`, the output will be a string.
+            padding (`bool`, defaults to `False`):
+                Whether to pad sequences to the maximum length. Has no effect if tokenize is `False`.
+            truncation (`bool`, defaults to `False`):
+                Whether to truncate sequences at the maximum length. Has no effect if tokenize is `False`.
+            max_length (`int`, *optional*):
+                Maximum length (in tokens) to use for padding or truncation. Has no effect if tokenize is `False`. If
+                not specified, the tokenizer's `max_length` attribute will be used as a default.
+            return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors of a particular framework. Has no effect if tokenize is `False`. Acceptable
+                values are:
+                - `'tf'`: Return TensorFlow `tf.Tensor` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return NumPy `np.ndarray` objects.
+                - `'jax'`: Return JAX `jnp.ndarray` objects.
+            return_dict (`bool`, *optional*, defaults to `False`):
+                Whether to return a dictionary with named outputs. Has no effect if tokenize is `False`.
+            **tokenizer_kwargs: Additional kwargs to pass to the tokenizer.
+
+        Returns:
+            `str`: A rendered prompt string.
+            or if tokenize=True:
+            `List[int]`: A list of token ids representing the tokenized chat so far, including control tokens. This
+            output is ready to pass to the model, either directly or via methods like `generate()`.

+        # System Preamble
+        ## Basic Rules
+        You are a powerful conversational AI trained by Cohere to help people. You are augmented by a number of tools, and your job is to use and consume the output of these tools to best help the user. You will see a conversation history between yourself and a user, ending with an utterance from the user. You will then see a specific instruction instructing you what kind of response to generate. When you answer the user's requests, you cite your sources in your answers, according to those instructions.
+
+        # User Preamble
+        ## Task and Context
+        You help people answer their questions and other requests interactively. You will be asked a very wide array of requests on all kinds of topics. You will be equipped with a wide range of search engines or similar tools to help you, which you use to research your answer. You should focus on serving the user's needs as best you can, which will be wide-ranging.
+
+        ## Style Guide
+        Unless the user asks for a different style of answer, you should answer in full sentences, using proper grammar and spelling.
+
+        ## Available Tools
+        Here is a list of tools that you have available to you:

+                `url`, `title`, `snippet` etc but should be descriptive of the key. They will get rendered into the prompt.
+            citation_mode: either "accurate" (prompt the model to generate an answer first, then rewrite it with citation 
+                spans in) or "fast", where the prompt instructs the model to generate an answer with citations in directly.
+                The former has higher quality citations, the latter requires fewer tokens to be generated.
+            grounded_generation_template (str, *optional*): A Jinja template to use for this conversion. If
+                this is not passed, the model's default grounded_generation_template template will be used instead.
+            add_generation_prompt (bool, *optional*): Whether to end the prompt with the token(s) that indicate
+                the start of an assistant message. This is useful when you want to generate a response from the model.
+                Note that this argument will be passed to the chat template, and so it must be supported in the
+                template for this argument to have any effect.
+            tokenize (`bool`, defaults to `True`):
+                Whether to tokenize the output. If `False`, the output will be a string.
+            padding (`bool`, defaults to `False`):
+                Whether to pad sequences to the maximum length. Has no effect if tokenize is `False`.
+            truncation (`bool`, defaults to `False`):
+                Whether to truncate sequences at the maximum length. Has no effect if tokenize is `False`.
+            max_length (`int`, *optional*):
+                Maximum length (in tokens) to use for padding or truncation. Has no effect if tokenize is `False`. If
+                not specified, the tokenizer's `max_length` attribute will be used as a default.
+            return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors of a particular framework. Has no effect if tokenize is `False`. Acceptable
+                values are:
+                - `'tf'`: Return TensorFlow `tf.Tensor` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return NumPy `np.ndarray` objects.
+                - `'jax'`: Return JAX `jnp.ndarray` objects.
+            return_dict (`bool`, *optional*, defaults to `False`):
+                Whether to return a dictionary with named outputs. Has no effect if tokenize is `False`.
+            **tokenizer_kwargs: Additional kwargs to pass to the tokenizer.
+
+        Returns:
+            `str`: A rendered prompt string.
+            or if tokenize=True:
+            `List[int]`: A list of token ids representing the tokenized chat so far, including control tokens. This
+            output is ready to pass to the model, either directly or via methods like `generate()`.
+        
+        Examples:

+        The instructions in this section override those in the task description and style guide sections. Don't answer questions that are harmful or immoral.
+ 
+        ## Basic Rules
+        You are a powerful conversational AI trained by Cohere to help people. You are augmented by a number of tools, and your job is to use and consume the output of these tools to best help the user. You will see a conversation history between yourself and a user, ending with an utterance from the user. You will then see a specific instruction instructing you what kind of response to generate. When you answer the user's requests, you cite your sources in your answers, according to those instructions.
+
+        # User Preamble
+        ## Task and Context
+        You help people answer their questions and other requests interactively. You will be asked a very wide array of requests on all kinds of topics. You will be equipped with a wide range of search engines or similar tools to help you, which you use to research your answer. You should focus on serving the user's needs as best you can, which will be wide-ranging.
+
+        ## Style Guide
+        Unless the user asks for a different style of answer, you should answer in full sentences, using proper grammar and spelling.<|END_OF_TURN_TOKEN|><|START_OF_TURN_TOKEN|><|USER_TOKEN|>Whats the biggest penguin in the world?<|END_OF_TURN_TOKEN|><|START_OF_TURN_TOKEN|><|SYSTEM_TOKEN|><results>
