<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.

The **Icosa Computing** components require access to Icosa Computing services.
For more information and to request access, see the [Icosa Computing site](https://www.icosacomputing.com/).

## Combinatorial Reasoner

The **Combinatorial Reasoner** component runs Icosa's Combinatorial Reasoning (CR) pipeline on an input to create an optimized prompt with embedded reasons.

### Combinatorial Reasoner parameters

| Name | Type | Description |
|------|------|-------------|
| prompt | String | Input parameter. The input to run CR on. |
| openai_api_key | SecretString | Input parameter. An OpenAI API key for authentication to OpenAI, which is used for reason generation. |
| model_name | String | Input parameter. The OpenAI LLM to use for reason generation. |
| username | String | Input parameter. A username for authentication to the Icosa API. |
| password | SecretString | Input parameter. A password for authentication to the Icosa API. |

### Combinatorial Reasoner outputs

The **Combinatorial Reasoner** component outputs one of the following:

* **Optimized Prompt (`optimized_prompt`)**: A [`Message`](/data-types#message) object containing the optimized prompt with embedded reasons.
* **Selected Reasons (`reasons`)**: A [`JSON`](/data-types#json) object containing a list of strings where each string is a reason that was selected and embedded in the optimized prompt.

You can toggle the output type near the component's output port.
