To host your LLM as a SageMaker endpoint, you generate a number of artifacts.

The primary artifact is mannequin weights. SageMaker Deep Java Library (DJL) Serving containers help you arrange configurations via a meta serving.properties file, which allows you to direct how fashions are sourced—both instantly from the Hugging Face Hub or by downloading mannequin artifacts from Amazon S3. For those who specify model_id=defog/sqlcoder-7b-2, DJL Serving will try and instantly obtain this mannequin from the Hugging Face Hub. Nevertheless, chances are you’ll incur networking ingress/egress costs every time the endpoint is deployed or elastically scaled. To keep away from these costs and probably pace up the obtain of mannequin artifacts, it is strongly recommended to skip utilizing model_id in serving.properties and save mannequin weights as S3 artifacts and solely specify them with s3url=s3://path/to/mannequin/bin.

Saving a mannequin (with its tokenizer) to disk and importing it to Amazon S3 might be achieved with only a few strains of code:

# save mannequin and tokenizer to native disk
mannequin.save_pretrained(local_model_path)
tokenizer.save_pretrained(local_model_path)
...
...
...
# add file to s3
s3_bucket_name = "<my llm artifact bucket title>>"
# s3 prefix to save lots of mannequin weights and tokenizer defs
model_s3_prefix = "sqlcoder-7b-instruct/weights"
# s3 prefix to retailer s
meta_model_s3_prefix = "sqlcoder-7b-instruct/meta-model"

sagemaker.s3.S3Uploader.add(local_model_path,  f"s3://{s3_bucket_name}/{model_s3_prefix}")

You additionally use a database immediate file. On this setup, the database immediate consists of Activity, Directions, Database Schema, and Reply sections. For the present structure, we allocate a separate immediate file for every database schema. Nevertheless, there may be flexibility to increase this setup to incorporate a number of databases per immediate file, permitting the mannequin to run composite joins throughout databases on the identical server. Throughout our prototyping stage, we save the database immediate as a textual content file named <Database-Glue-Connection-Identify>.immediate, the place Database-Glue-Connection-Identify corresponds to the connection title seen in your JupyterLab setting. As an example, this put up refers to a Snowflake connection named Airlines_Dataset, so the database immediate file is known as Airlines_Dataset.immediate. This file is then saved on Amazon S3 and subsequently learn and cached by our mannequin serving logic.

Furthermore, this structure permits any licensed customers of this endpoint to outline, retailer, and generate pure language to SQL queries with out the necessity for a number of redeployments of the mannequin. We use the next example of a database prompt to show the Textual content-to-SQL performance.

Subsequent, you generate customized mannequin service logic. On this part, you define a customized inference logic named model.py. This script is designed to optimize the efficiency and integration of our Textual content-to-SQL companies:

• Outline the database immediate file caching logic – To attenuate latency, we implement a customized logic for downloading and caching database immediate information. This mechanism makes positive that prompts are available, decreasing the overhead related to frequent downloads.
• Outline customized mannequin inference logic – To boost inference pace, our text-to-SQL mannequin is loaded within the float16 precision format after which transformed right into a DeepSpeed mannequin. This step permits for extra environment friendly computation. Moreover, inside this logic, you specify which parameters customers can regulate throughout inference calls to tailor the performance in response to their wants.
• Outline customized enter and output logic – Establishing clear and customised enter/output codecs is crucial for clean integration with downstream purposes. One such software is JupyterAI, which we talk about within the subsequent part.

%%writefile {meta_model_filename}/mannequin.py
...

predictor = None
prompt_for_db_dict_cache = {}

def download_prompt_from_s3(prompt_filename):

    print(f"downloading immediate file: {prompt_filename}")
    s3 = boto3.useful resource('s3')
    ...


def get_model(properties):
    
    ...
    print(f"Loading mannequin from {cwd}")
    mannequin = AutoModelForCausalLM.from_pretrained(
        cwd, 
        low_cpu_mem_usage=True, 
        torch_dtype=torch.bfloat16
    )
    mannequin = deepspeed.init_inference(
        mannequin, 
        mp_size=properties["tensor_parallel_degree"]
    )
    
    ...


def deal with(inputs: Enter) -> None:

    ...

    world predictor
    if not predictor:
        predictor = get_model(inputs.get_properties())

    ...
    consequence = f"""%%sm_sql --metastore-id {prompt_for_db_key.cut up('.')[0]} --metastore-type GLUE_CONNECTIONnn{consequence}n"""
    consequence = [{'generated_text': result}]
    
    return Output().add(consequence)

Moreover, we embody a serving.properties file, which acts as a world configuration file for fashions hosted utilizing DJL serving. For extra data, confer with Configurations and settings.

Lastly, you may as well embody a necessities.txt file to outline extra modules required for inference and package deal all the pieces right into a tarball for deployment.

See the next code:

os.system(f"tar czvf {meta_model_filename}.tar.gz ./{meta_model_filename}/")

Combine your endpoint with the SageMaker Studio Jupyter AI assistant

Jupyter AI is an open supply device that brings generative AI to Jupyter notebooks, providing a strong and user-friendly platform for exploring generative AI fashions. It enhances productiveness in JupyterLab and Jupyter notebooks by offering options just like the %%ai magic for making a generative AI playground inside notebooks, a local chat UI in JupyterLab for interacting with AI as a conversational assistant, and assist for a wide selection of LLMs from suppliers like Amazon Titan, AI21, Anthropic, Cohere, and Hugging Face or managed companies like Amazon Bedrock and SageMaker endpoints. For this put up, we use Jupyter AI’s out-of-the-box integration with SageMaker endpoints to carry the Textual content-to-SQL functionality into JupyterLab notebooks. The Jupyter AI device comes pre-installed in all SageMaker Studio JupyterLab Areas backed by SageMaker Distribution images; end-users aren’t required to make any extra configurations to begin utilizing the Jupyter AI extension to combine with a SageMaker hosted endpoint. On this part, we talk about the 2 methods to make use of the built-in Jupyter AI device.

Jupyter AI inside a pocket book utilizing magics

Jupyter AI’s %%ai magic command permits you to rework your SageMaker Studio JupyterLab notebooks right into a reproducible generative AI setting. To start utilizing AI magics, be sure you have loaded the jupyter_ai_magics extension to make use of %%ai magic, and moreover load amazon_sagemaker_sql_magic to make use of %%sm_sql magic:

# load sm_sql magic extension and ai magic extension
%load_ext jupyter_ai_magics
%load_ext amazon_sagemaker_sql_magic

To run a name to your SageMaker endpoint out of your pocket book utilizing the %%ai magic command, present the next parameters and construction the command as follows:

• –region-name – Specify the Area the place your endpoint is deployed. This makes positive that the request is routed to the right geographic location.
• –request-schema – Embody the schema of the enter information. This schema outlines the anticipated format and forms of the enter information that your mannequin must course of the request.
• –response-path – Outline the trail inside the response object the place the output of your mannequin is situated. This path is used to extract the related information from the response returned by your mannequin.
• -f (non-compulsory) – That is an output formatter flag that signifies the kind of output returned by the mannequin. Within the context of a Jupyter pocket book, if the output is code, this flag must be set accordingly to format the output as executable code on the prime of a Jupyter pocket book cell, adopted by a free textual content enter space for consumer interplay.

For instance, the command in a Jupyter pocket book cell may appear like the next code:

%%ai sagemaker-endpoint:<endpoint-name> --region-name=us-east-1 
--request-schema={
    "inputs":"<immediate>", 
    "parameters":{
        "temperature":0.1,
        "top_p":0.2,
        "max_new_tokens":1024,
        "return_full_text":false
    }, 
    "db_prompt":"Airlines_Dataset.immediate"
  } 
--response-path=[0].generated_text -f code

My pure language question goes right here...
