## Description

The Cohere model, developed by Cohere Inc, is a language model that combines the power of GPT (Generative Pre-trained Transformer) with LLM (Language Model for Legal Text). It is specifically designed to understand and generate legal text, making it useful for tasks such as legal document analysis, contract generation, and legal research. The model has been trained on a large corpus of legal documents to ensure accuracy and relevance in its responses.

The Cohere component allows you to integrate Cohere into your flows. You can customize the parameters used by Cohere component, and also specify the context of knowledge that the Cohere component operates on, as well as provide the input query. Both the context and the query are given to the Cohere component by specifying Diaflow component identifiers. For example, the above screenshot shows the default user message of **trigger.text** which is a Text Input component.&#x20;

The Cohere component has the identifier of an-**X**, where **X** represents the instance number of the Cohere component.

## Inputs

The Cohere component has the following input connections.

| Input Name                               | Description                                                                   | Constraints                                                                                                      |
| ---------------------------------------- | ----------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- |
| From data Loaders/ Data source/Vector DB | This input connection represents the context information for the Cohere model | Must originate from a Data Loader/Data Source or VectorDB component.                                             |
| From Input                               | This input connection represents the user query for the Cohere model.         | Must originate from a component that generates a text string as output such as a Python or Text Input component. |

## Component settings

| Parameter Name | Description                                                                                                                                                                                        |
| -------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Model          | <p>This parameter specifies the version of Cohere that the component should use. </p><p></p><p>Available values:</p><ul><li>Command R+</li><li>Command R</li></ul>                                 |
| Prompt         | Describes how you want the Cohere model to respond. For example, you can specify the role, manner and rules that Cohere should adhere to. Also mention the component ID to connect the components. |
| Image source   | Adding an image to your prompt by identify a trigger file in this configuration.                                                                                                                   |

## Advanced configurations

| Options        | Description                                                                                                                                                                                                               |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Enable caching | This option determines whether the results of the component are cached. This means that on the next run of the Flow, Diaflow will utilize the previous computed component output, as long as the inputs have not changed. |
| Caching time   | <p>Only applicable if the "Enable Caching" option has been enabled.<br>This parameter controls how long Diaflow will wait before automatically clearing the cache.</p>                                                    |

## Outputs

The Cohere component has the following output connections.

| Output Name | Description                                                              | Constraints                                                    |
| ----------- | ------------------------------------------------------------------------ | -------------------------------------------------------------- |
| To Output   | This output connection contains the text result of the Cohere component. | Can be connected to any component that accepts a string input. |

## Use case

Here is a simple use case of the Cohere component, where the Cohere component is being used to provide the user the ability to ask the Cohere component questions via a Text Input component.
