Use DeepSeek with Amazon OpenSearch Service vector database and Amazon SageMaker

DeepSeek-R1 is a strong and cost-effective AI mannequin that excels at advanced reasoning duties. When mixed with Amazon OpenSearch Service, it allows sturdy Retrieval Augmented Era (RAG) purposes. This put up exhibits you the right way to arrange RAG utilizing DeepSeek-R1 on Amazon SageMaker with an OpenSearch Service vector database because the information base. This instance gives an answer for enterprises seeking to improve their AI capabilities.

OpenSearch Service gives wealthy capabilities for RAG use circumstances, in addition to vector embedding-powered semantic search. You need to use the versatile connector framework and search circulate pipelines in OpenSearch to hook up with fashions hosted by DeepSeek, Cohere, and OpenAI, in addition to fashions hosted on Amazon Bedrock and SageMaker. On this put up, we construct a connection to DeepSeek’s textual content era mannequin, supporting a RAG workflow to generate textual content responses to person queries.

Answer overview

The next diagram illustrates the answer structure.

On this walkthrough, you’ll use a set of scripts to create the previous structure and knowledge circulate. First, you’ll create an OpenSearch Service area, and deploy DeepSeek-R1 to SageMaker. You’ll execute scripts to create an AWS Identification and Entry Administration (IAM) function for invoking SageMaker, and a job to your person to create a connector to SageMaker. You’ll create an OpenSearch connector and mannequin that can allow the retrieval_augmented_generation processor inside OpenSearch to execute a person question, carry out a search, and use DeepSeek to generate a textual content response. You’ll create a connector to SageMaker with Amazon Titan Textual content Embeddings V2 to create embeddings for a set of paperwork with inhabitants statistics. Lastly, you’ll execute the question to match inhabitants development in Miami and New York Metropolis.

Conditions

We’ve created and open-sourced a GitHub repo with all of the code it is advisable observe together with the put up and deploy it for your self. You will want the next stipulations:

Deploy DeepSeek on Amazon SageMaker

You will want to have or deploy DeepSeek with an Amazon SageMaker endpoint. To study extra about deploying DeepSeek-R1 on SageMaker, check with Deploying DeepSeek-R1 Distill Mannequin on AWS utilizing Amazon SageMaker AI.

Create an OpenSearch Service area

Seek advice from Create an Amazon OpenSearch Service area for directions on the right way to create your area. Make word of the area Amazon Useful resource Identify (ARN) and area endpoint, each of which might be discovered within the Common info part of every area on the OpenSearch Service console.

Obtain and put together the code

Run the next steps out of your native laptop or workspace that has Python and git:

  1. If you happen to haven’t already, clone the repo into an area folder utilizing the next command:
git clone https://github.com/Jon-AtAWS/opensearch-examples.git

  1. Create a Python digital setting:
cd opensearch-examples/opensearch-deepseek-rag python -m venv .venv supply .venv/bin/activate pip set up -r necessities.txt

The instance scripts use setting variables for setting some frequent parameters. Set these up now utilizing the next instructions. Remember to replace together with your AWS Area, your SageMaker endpoint ARN and URL, your OpenSearch Service area’s endpoint and ARN, and your area’s main person and password.

export DEEPSEEK_AWS_REGION='' export SAGEMAKER_MODEL_INFERENCE_ARN=''  export SAGEMAKER_MODEL_INFERENCE_ENDPOINT='' export OPENSEARCH_SERVICE_DOMAIN_ARN='’ export OPENSEARCH_SERVICE_DOMAIN_ENDPOINT='' export OPENSEARCH_SERVICE_ADMIN_USER='' export OPENSEARCH_SERVICE_ADMIN_PASSWORD=''

You now have the code base and have your digital setting arrange. You possibly can look at the contents of the opensearch-deepseek-rag listing. For readability of function and studying, we’ve encapsulated every of seven steps in its personal Python script. This put up will information you thru operating these scripts. We’ve additionally chosen to make use of setting variables to cross parameters between scripts. In an precise resolution, you’d encapsulate the code in courses and cross the values the place wanted. Coding this fashion is clearer, however is much less environment friendly and doesn’t observe coding greatest practices. Use these scripts as examples to drag from.

First, you’ll arrange permissions to your OpenSearch Service area to hook up with your SageMaker endpoint.

Arrange permissions

You’ll create two IAM roles. The primary will enable OpenSearch to name your SageMaker endpoint. The second will will let you make the create connector API name to OpenSearch.

  1. Look at the code in create_invoke_role.py.
  2. Return to the command line, and execute the script:
python create_invoke_role.py

  1. Execute the command line from the script’s output to set the INVOKE_DEEPSEEK_ROLE setting variable.

You’ve gotten created a job named invoke_deepseek_role, with a belief relationship for OpenSearch Service to imagine the function, and with a permission coverage that enables OpenSearch Service to invoke your SageMaker endpoint. The script outputs the ARNs to your function and coverage and moreover a command line command so as to add the function to your setting. Execute that command earlier than operating the subsequent script. Make an observation of the function ARN in case it is advisable return at a later time.

Now it is advisable create a job to your person to have the ability to create a connector in OpenSearch Service.

  1. Look at the code in create_connector_role.py.
  2. Return to the command line and execute the script:
python create_connector_role.py

  1. Execute the command line from the script’s output to set the CREATE_DEEPSEEK_CONNECTOR_ROLE setting variable.

You’ve gotten created a job named create_deepseek_connector_role, with a belief relationship with the present person and permissions to put in writing to OpenSearch Service. You want these permissions to name the OpenSearch create_connector API, which packages a connection to a distant mannequin host, DeepSeek on this case. The script prints the coverage’s and function’s ARNs, and moreover a command line command so as to add the function to your setting. Execute that command earlier than operating the subsequent script. Once more, make word of the function ARN, simply in case.

Now that you’ve your roles created, you’ll inform OpenSearch about them. The fine-grained entry management function consists of an OpenSearch function, ml_full_access, that can enable authenticated entities to execute API calls inside OpenSearch.

  1. Look at the code in setup_opensearch_security.py.
  2. Return to the command line and execute the script:
python setup_opensearch_security.py

You arrange the OpenSearch Service safety plugin to acknowledge two AWS roles: invoke_create_connector_role and LambdaInvokeOpenSearchMLCommonsRole. You’ll use the second function later, once you join with an embedding mannequin and cargo knowledge into OpenSearch to make use of as a RAG information base. Now that you’ve permissions in place, you possibly can create the connector.

Create the connector

You create a connector with configuration that tells OpenSearch the right way to join, gives credentials for the goal mannequin host, and gives immediate particulars. For extra info, see Creating connectors for third-party ML platforms.

  1. Look at the code in create_connector.py.
  2. Return to the command line and execute the script:
python create_connector.py

  1. Execute the command line from the script’s output to set the DEEPSEEK_CONNECTOR_ID setting variable.

The script will create the connector to name the SageMaker endpoint and return the connector ID. The connector is an OpenSearch assemble that tells OpenSearch how to hook up with an exterior mannequin host. You don’t use it instantly; you create an OpenSearch mannequin for that.

Create an OpenSearch mannequin

While you work with machine studying (ML) fashions, in OpenSearch, you utilize OpenSearch’s ml-commons plugin to create a mannequin. ML fashions are an OpenSearch abstraction that allow you to carry out ML duties like sending textual content for embeddings throughout indexing, or calling out to a big language mannequin (LLM) to generate textual content in a search pipeline. The mannequin interface gives you with a mannequin ID in a mannequin group that you simply then use in your ingest pipelines and search pipelines.

  1. Look at the code in create_deepseek_model.py.
  2. Return to the command line and execute the script:
python create_deepseek_model.py

  1. Execute the command line from the script’s output to set the DEEPSEEK_MODEL_ID setting variable.

You created an OpenSearch ML mannequin group and mannequin that you should utilize to create ingest and search pipelines. The _register API locations the mannequin within the mannequin group and references your SageMaker endpoint by means of the connector (connector_id) you created.

Confirm your setup

You possibly can run a question to confirm your setup and just be sure you can connect with DeepSeek on SageMaker and obtain generated textual content. Full the next steps:

  1. On the OpenSearch Service console, select Dashboard beneath Managed clusters within the navigation pane.
  2. Select your area’s dashboard.

  1. Select the OpenSearch Dashboards URL (twin stack) hyperlink to open OpenSearch Dashboards.
  2. Log in to OpenSearch Dashboards together with your main person title and password.
  3. Dismiss the welcome dialog by selecting Discover alone.
  4. Dismiss the brand new appear and feel dialog.
  5. Affirm the worldwide tenant within the Choose your tenant dialog.
  6. Navigate to the Dev Instruments tab.
  7. Dismiss the welcome dialog.

You can too get to Dev Instruments by increasing the navigation menu (three strains) to disclose the navigation pane, and scrolling right down to Dev Instruments.

OpenSearch Dashboards home screen, with an indicator on where to click to open the Dev Tools tab

The Dev Instruments web page gives a left pane the place you enter REST API calls. You execute the instructions and the suitable pane exhibits the output of the command. Enter the next command within the left pane, exchange your_model_id with the mannequin ID you created, and run the command by putting the cursor anyplace within the command and selecting the run icon.

POST _plugins/_ml/fashions//_predict{  "parameters": {    "inputs": "Hey"  }}

You need to see output like the next screenshot.

Congratulations! You’ve now created and deployed an ML mannequin that may use the connector you created to name to your SageMaker endpoint, and use DeepSeek to generate textual content. Subsequent, you’ll use your mannequin in an OpenSearch search pipeline to automate a RAG workflow.

Arrange a RAG workflow

RAG is a approach of including info to the immediate in order that the LLM producing the response is extra correct. An total generative utility like a chatbot orchestrates a name to exterior information bases and augments the immediate with information from these sources. We’ve created a small information base comprising inhabitants info.

OpenSearch gives search pipelines, that are units of OpenSearch search processors which might be utilized to the search request sequentially to construct a remaining outcome. OpenSearch has processors for hybrid search, reranking, and RAG, amongst others. You outline your processor after which ship your queries to the pipeline. OpenSearch responds with the ultimate outcome.

While you construct a RAG utility, you select a information base and a retrieval mechanism. Most often, you’ll use an OpenSearch Service vector database as a information base, performing a k-nearest neighbor (k-NN) search to include semantic info within the retrieval with vector embeddings. OpenSearch Service gives integrations with vector embedding fashions hosted in Amazon Bedrock and SageMaker (amongst different choices).

Ensure that your area is operating OpenSearch 2.9 or later, and that fine-grained entry management is enabled for the area. Then full the next steps:

  1. On the OpenSearch Service console, select Integrations within the navigation pane.
  2. Select Configure area beneath Integration with textual content embedding fashions by means of Amazon SageMaker.

  1. Select Configure public area.
  2. If you happen to created a digital personal cloud (VPC) area as a substitute, select Configure VPC area.

You may be redirected to the AWS CloudFormation console.

  1. For Amazon OpenSearch Endpoint, enter your endpoint.
  2. Go away every little thing else as default values.

The CloudFormation stack requires a job to create a connector to the all-MiniLM-L6-v2 mannequin, hosted on SageMaker, known as LambdaInvokeOpenSearchMLCommonsRole. You enabled entry for this function once you ran setup_opensearch_security.py. If you happen to modified the title in that script, remember to change it within the Lambda Invoke OpenSearch ML Commons Position Identify area.

  1. Choose I acknowledge that AWS CloudFormation would possibly create IAM sources with customized names, and select Create stack.

For simplicity, we’ve elected to make use of the open supply all-MiniLM-L6-v2 mannequin, hosted on SageMaker for embedding era. To attain excessive search high quality for manufacturing workloads, it is best to fine-tune light-weight fashions like all-MiniLM-L6-v2, or use OpenSearch Service integrations with fashions corresponding to Cohere Embed V3 on Amazon Bedrock or Amazon Titan Textual content Embedding V2, that are designed to ship excessive out-of-the-box high quality.

Look ahead to CloudFormation to deploy your stack and the standing to alter to Create_Complete.

  1. Select the stack’s Outputs tab on the CloudFormation console and replica the worth for ModelID.

You’ll use this mannequin ID to attach together with your embedding mannequin.

  1. Look at the code in load_data.py.
  2. Return to the command line and set an setting variable with the mannequin ID of the embedding mannequin:
export EMBEDDING_MODEL_ID=''

  1. Execute the script to load knowledge into your area:

The script creates the population_data index and an OpenSearch ingest pipeline that calls SageMaker utilizing the connector referenced by the embedding mannequin ID. The ingest pipeline’s area mapping tells OpenSearch the supply and vacation spot fields for every doc’s embedding.

Now that you’ve your information base ready, you possibly can run a RAG question.

  1. Look at the code in run_rag.py.
  2. Return to the command line and execute the script:

The script creates a search pipeline with an OpenSearch retrieval_augmented_generation processor. The processor automates operating an OpenSearch k-NN question to retrieve related info and including that info to the immediate. It makes use of the generation_model_id and connector to the DeepSeek mannequin on SageMaker to generate a textual content response for the person’s query. The OpenSearch neural question (line 55 of run_rag.py) takes care of producing the embedding for the k-NN question utilizing the embedding_model_id. Within the ext part of the question, you present the person’s query for the LLM. The llm_model is ready to bedrock/claude as a result of the parameterization and actions are the identical as they’re for DeepSeek. You’re nonetheless utilizing DeepSeek to generate textual content.

Look at the output from OpenSearch Service. The person requested the query “What’s the inhabitants enhance of New York Metropolis from 2021 to 2023? How is the trending evaluating with Miami?” The primary portion of the outcome exhibits the hits—paperwork OpenSearch retrieved from the semantic question—because the inhabitants statistics for New York Metropolis and Miami. The following part of the response consists of the immediate, in addition to DeepSeek’s reply.

Okay, so I would like to determine the inhabitants enhance of New York Metropolis from 2021 to 2023 and examine it with Miami's development.  Let me begin by wanting on the knowledge supplied within the search outcomes. From SEARCH RESULT 2, I see that in 2021, NYC had a inhabitants of 18,823,000.  In 2022, it was 18,867,000, and in 2023, it is 18,937,000.  So, the rise from 2021 to 2022 is eighteen,867,000 - 18,823,000 = 44,000.  Then from 2022 to 2023, it is 18,937,000 - 18,867,000 = 70,000.  Including these collectively, the entire enhance from 2021 to 2023 is 44,000 + 70,000 = 114,000. Now, taking a look at Miami's knowledge in SEARCH RESULT 1. In 2021, Miami's inhabitants was 6,167,000, in 2022 it was 6,215,000, and in 2023 it is 6,265,000.  The rise from 2021 to 2022 is 6,215,000 - 6,167,000 = 48,000. From 2022 to 2023, it is 6,265,000 - 6,215,000 = 50,000.  So, the entire enhance is 48,000 + 50,000 = 98,000.Evaluating the 2, NYC's enhance of 114,000 is increased than Miami's 98,000.  So, NYC's inhabitants elevated extra over that interval."

Congratulations! You’ve linked to an embedding mannequin, created a information base, and used that information base, together with DeepSeek, to generate a textual content response to a query on inhabitants modifications in New York Metropolis and Miami. You possibly can adapt the code from this put up to create your individual information base and run your individual queries.

Clear up

To keep away from incurring extra expenses, clear up the sources you deployed:

  1. Delete the SageMaker deployment of DeepSeek. For directions, see Cleansing Up.
  2. In case your Jupyter pocket book has misplaced context, you possibly can delete the endpoint:
    1. On the SageMaker console, beneath Inference within the navigation pane, select Endpoints.
    2. Choose your endpoint and select Delete.
  3. Delete the CloudFormation template for connecting to SageMaker for the embedding mannequin.
  4. Delete the OpenSearch Service area you created.

Conclusion

The OpenSearch connector framework is a versatile approach so that you can entry fashions you host on different platforms. On this instance, you linked to the open supply DeepSeek mannequin that you simply deployed on SageMaker. DeepSeek’s reasoning capabilities, augmented with a information base within the OpenSearch Service vector engine, enabled it to reply a query evaluating inhabitants development in New York and Miami.
