<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.
The **IBM** bundle provides access to IBM watsonx.ai models for text and embedding generation, plus an IBM Db2 Vector Store.
These components require an IBM watsonx.ai deployment with API credentials, and/or a reachable IBM Db2 instance with the `ibm-db` driver.
## Install the IBM bundle
The **IBM** bundle is included in the `lfx-ibm` Extension bundle, which is installed automatically as part of `uv pip install langflow`.
If you need to install it separately, run:
```bash
uv pip install lfx-ibm
uv run langflow run
```
To verify the bundle is loaded in your environment:
```bash
lfx extension list
```
## IBM watsonx.ai
The **IBM watsonx.ai** component generates text using [supported foundation models](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-models.html?context=wx) in [IBM watsonx.ai](https://www.ibm.com/products/watsonx-ai).
To use gateway models, use the [**OpenAI** text generation component](/bundles-openai) with the gateway model's OpenAI-compatible endpoint.
You can use the **IBM watsonx.ai** component anywhere you need a language model in a flow.

### IBM watsonx.ai output
The **IBM watsonx.ai** component 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 an IBM watsonx.ai 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).
The `LanguageModel` output from the **IBM watsonx.ai** component is an instance of `[ChatWatsonx](https://docs.langchain.com/oss/python/integrations/chat/ibm_watsonx)` configured according to the [component's parameters](#ibm-watsonxai-parameters).
## IBM watsonx.ai Embeddings
The **IBM watsonx.ai Embeddings** component uses the [supported foundation models](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-models.html?context=wx) in [IBM watsonx.ai](https://www.ibm.com/products/watsonx-ai) for embedding generation.
The output is [`Embeddings`](/data-types#embeddings) generated with [`WatsonxEmbeddings`](https://python.langchain.com/docs/integrations/text_embedding/ibm_watsonx/).
For more information about using embedding model components in flows, see [Embedding model components](/components-embedding-models).

### IBM watsonx.ai Embeddings parameters
<PartialParams />
| Name | Display Name | Info |
|------|--------------|------|
| url | watsonx API Endpoint | Input parameter. The [watsonx API base URL](https://cloud.ibm.com/apidocs/watsonx-ai#endpoint-url) for your deployment and region. |
| project_id | watsonx project id | Input parameter. Your [watsonx Project ID](https://www.ibm.com/docs/en/watsonx/saas?topic=projects). |
| api_key | API Key | Input parameter. A [watsonx API key](https://www.ibm.com/docs/en/watsonx/saas?topic=administration-managing-user-api-key) to authenticate watsonx API access to the specified watsonx.ai deployment and model. |
| model_name | Model Name | Input parameter. The name of the embedding model to use. Supports [default embedding models](#default-embedding-models) and automatically updates after connecting to your watsonx.ai deployment. |
| truncate_input_tokens | Truncate Input Tokens | Input parameter. The maximum number of tokens to process. Default: `200`. |
| input_text | Include the original text in the output | Input parameter. Determines if the original text is included in the output. Default: `true`. |
### Default embedding models
By default, the **IBM watsonx.ai Embeddings** component supports the following default models:
- `sentence-transformers/all-minilm-l12-v2`: 384-dimensional embeddings
- `ibm/slate-125m-english-rtrvr-v2`: 768-dimensional embeddings
- `ibm/slate-30m-english-rtrvr-v2`: 768-dimensional embeddings
- `intfloat/multilingual-e5-large`: 1024-dimensional embeddings
After entering your API endpoint and credentials, the component automatically fetches the list of available models from your watsonx.ai deployment.
## IBM Db2 Vector Store
You can use the **IBM Db2 Vector Store** component to read and write to an IBM Db2 database using an instance of `DB2VS` vector store.
Includes support for remote Db2 instances with enterprise-grade security and performance.

When writing, the component can create a new table at the specified location.
:::tip
IBM Db2 Vector Store provides enterprise-grade vector search capabilities with built-in security validation and support for multiple distance strategies.

### Use the IBM Db2 Vector Store component in a flow
The **IBM Db2 Vector Store** component can be used for both reads and writes:
* When writing, it splits `JSON` from a [**URL** component](/url) into chunks, computes embeddings with attached **Embedding Model** component, and then loads the chunks and embeddings into the Db2 vector store.
To trigger writes, click <Icon name="Play" aria-hidden="true"/> **Run component** on the **IBM Db2 Vector Store** component.
* When reading, it uses chat input to perform a similarity search on the vector store, and then print the search results to the chat.
To trigger reads, open the **Playground** and enter a chat message.
After running the flow once, you can click <Icon name="TextSearch" aria-hidden="true"/> **Inspect Output** on each component to understand how the data transformed as it passed from component to component.
### IBM Db2 Vector Store parameters
You can inspect a vector store component's parameters to learn more about the inputs it accepts, the features it supports, and how to configure it.
