# Bedrock LLM and Embeddings
This PR adds a new LLM and an Embeddings class for the
[Bedrock](https://aws.amazon.com/bedrock) service. The PR also includes
example notebooks for using the LLM class in a conversation chain and
embeddings usage in creating an embedding for a query and document.

**Note**: AWS is doing a private release of the Bedrock service on
05/31/2023; users need to request access and added to an allowlist in
order to start using the Bedrock models and embeddings. Please use the
[Bedrock Home Page](https://aws.amazon.com/bedrock) to request access
and to learn more about the models available in Bedrock.

+
+>[Airbyte](https://github.com/airbytehq/airbyte) is a data integration platform for ELT pipelines from APIs, 
+> databases & files to warehouses & lakes. It has the largest catalog of ELT connectors to data warehouses and databases.
+
+## Installation and Setup
+
+This instruction shows how to load any source from `Airbyte` into a local `JSON` file that can be read in as a document.
+
+**Prerequisites:**
+Have `docker desktop` installed.
+
+**Steps:**
+1. Clone Airbyte from GitHub - `git clone https://github.com/airbytehq/airbyte.git`.
+2. Switch into Airbyte directory - `cd airbyte`.
+3. Start Airbyte - `docker compose up`.
+4. In your browser, just visit http://localhost:8000. You will be asked for a username and password. By default, that's username `airbyte` and password `password`.
+5. Setup any source you wish.
+6. Set destination as Local JSON, with specified destination path - lets say `/json_data`. Set up a manual sync.
+7. Run the connection.
+8. To see what files are created, navigate to: `file:///tmp/airbyte_local/`.

+>- Hourly forecast for 48 hours
+>- Daily forecast for 8 days
+>- National weather alerts

+# SageMaker Endpoint
+
+>[Amazon SageMaker](https://aws.amazon.com/sagemaker/) is a system that can build, train, and deploy machine learning (ML) models with fully managed infrastructure, tools, and workflows.
+
+We use `SageMaker` to host our model and expose it as the `SageMaker Endpoint`.
+
+
+## Installation and Setup
+
+```bash
+pip install boto3
+```
+
+For instructions on how to expose model as a `SageMaker Endpoint`, please see [here](https://www.philschmid.de/custom-inference-huggingface-sagemaker). 
+
+**Note**: In order to handle batched requests, we need to adjust the return line in the `predict_fn()` function within the custom `inference.py` script:
+
+Change from
+
+```
+return {"vectors": sentence_embeddings[0].tolist()}
+```
+
+to:
+
+```
+return {"vectors": sentence_embeddings.tolist()}
+```
+
+
+
+We have to set up following required parameters of the `SagemakerEndpoint` call:
+- `endpoint_name`: The name of the endpoint from the deployed Sagemaker model.
+    Must be unique within an AWS Region.
+- `credentials_profile_name`: The name of the profile in the ~/.aws/credentials or ~/.aws/config files, which
+    has either access keys or role information specified.
+    If not specified, the default credential profile or, if on an EC2 instance,
+    credentials from IMDS will be used.
+    See [this guide](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html).
+
+## LLM
+
+See a [usage example](../modules/models/llms/integrations/sagemaker.ipynb).
+
+```python
+from langchain import SagemakerEndpoint
