 jupyter lab --AiExtension.allowed_providers=openai --AiExtension.allowed_providers=ai21
 ```
+
+### Model parameters
+
+This configuration allows specifying arbitrary parameters that are unpacked and
+passed to the provider class. This is useful for passing parameters such as
+model tuning that affect the response generation by the model. This is also an
+appropriate place to pass in custom attributes required by certain
+providers/models.
+
+The accepted value is a dictionary, with top level keys as the model id
+(provider:model_id), and value should be any arbitrary dictionary which is
+unpacked and passed as-is to the provider class.
+
+#### Configuring as a startup option
+
+In this sample, the `bedrock` provider will be created with the value for
+`model_kwargs` when `ai21.j2-mid-v1` model is selected.
+
+```bash
+jupyter lab --AiExtension.model_parameters bedrock:ai21.j2-mid-v1='{"model_kwargs":{"maxTokens":200}}'
+```
+
+Note the usage of single quotes surrounding the dictionary to escape the double
+quotes. This is required in some shells. The above will result in the following
+LLM class to be generated.
+
+```python
+BedrockProvider(model_kwargs={"maxTokens":200}, ...)
+```
+
+Here is another example, where `anthropic` provider will be created with the
+values for `max_tokens` and `temperature`, when `claude-2` model is selected.
+
+
+```bash
+jupyter lab --AiExtension.model_parameters anthropic:claude-2='{"max_tokens":1024,"temperature":0.9}'
+```
+
+The above will result in the following LLM class to be generated.
+
+```python
+AnthropicProvider(max_tokens=1024, temperature=0.9, ...)
+```
+
+To pass multiple sets of model parameters for multiple models in the
+command-line, you can append them as additional arguments to
+`--AiExtension.model_parameters`, as shown below.
+
+```bash
+jupyter lab \
+--AiExtension.model_parameters bedrock:ai21.j2-mid-v1='{"model_kwargs":{"maxTokens":200}}' \
+--AiExtension.model_parameters anthropic:claude-2='{"max_tokens":1024,"temperature":0.9}'
+```
+
+However, for more complex configuration, we highly recommend that you specify
+this in a dedicated configuration file. We will describe how to do so in the
+following section.
+
+#### Configuring as a config file
+
+This configuration can also be specified in a config file in json format. The
+file should be named `jupyter_jupyter_ai_config.json` and saved in a path that
+JupyterLab can pick from. You can find this path by running `jupyter --paths`
+command, and picking one of the paths from the `config` section.
+
+Here is an example of running the `jupyter --paths` command.
+
+```bash
+(jupyter-ai-lab4) ➜ jupyter --paths
+config:
+    /opt/anaconda3/envs/jupyter-ai-lab4/etc/jupyter
+    /Users/3coins/.jupyter
+    /Users/3coins/.local/etc/jupyter
+    /usr/3coins/etc/jupyter
+    /etc/jupyter
+data:
+    /opt/anaconda3/envs/jupyter-ai-lab4/share/jupyter
+    /Users/3coins/Library/Jupyter
+    /Users/3coins/.local/share/jupyter
+    /usr/local/share/jupyter
+    /usr/share/jupyter
+runtime:
+    /Users/3coins/Library/Jupyter/runtime
+```
+
+Here is an example for configuring the `bedrock` provider for `ai21.j2-mid-v1`
+model.
+
+```json
+{
+    "AiExtension": {
+        "model_parameters": {
+            "bedrock:ai21.j2-mid-v1": {
+                "model_kwargs": {
+                    "maxTokens": 200
+                }
+            }
+        }
+    }
+}
+```
