* fix: nightly now properly gets 1.9.0 branch (#12215) before it was attempting to pull release-notes as letters are alphanumerically after numbers when we sort -V then grab tail now we only look at branch names that follow the pattern '^release-[0-9]+\.[0-9]+\.[0-9]+$' * docs: add search icon (#12216) add-back-svg * initial-content * cut-1.8-release-and-include-next-version * stage-1.8.0-and-next --------- Co-authored-by: Adam-Aghili <149833988+Adam-Aghili@users.noreply.github.com>

<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.
|
|
|
|
This page describes the components that are available in the **Cohere** bundle.
|
|
|
|
For more information about Cohere features and functionality used by Cohere components, see the [Cohere documentation](https://cohere.ai/).
|
|
|
|
## Cohere text generation
|
|
|
|
This component generates text using Cohere's language models.
|
|
|
|
It can output either a **Model Response** ([`Message`](/data-types#message)) or a **Language Model** ([`LanguageModel`](/data-types#languagemodel)).
|
|
|
|
Use the **Language Model** output when you want to use a Cohere model as the LLM for another LLM-driven component, such as an **Agent** or **Smart Transform** component.
|
|
|
|
For more information, see [Language model components](/components-models).
|
|

|
|
<PartialParams />
|
|
|
|
| Name | Type | Description |
|
|
|------|------|-------------|
|
|
| Input | String | Input parameter. Specifies the input text for text generation. |

|
## Cohere Embeddings
|
|
|
|
The **Cohere Embeddings** component is used to load embedding models from Cohere.
|
|
|
|
For more information about using embedding model components in flows, see [Embedding model components](/components-embedding-models).
