LLMs

Sagify provides a set of intuitive command-line interface (CLI) commands to simplify the management of Large Language Model (LLM) infrastructure. Whether you're exploring proprietary LLM models or open-source ones, or you want to use them in production, Sagify has you covered.

You can run sagify llm platforms to get a list of all supported backend LLM platforms:

  • OpenAI
  • AWS Sagemaker. This option enables you to deploy open-source LLMs to AWS and leverage the powerful AWS computing platform.

The architectural design of the Sagify LLM Gateway is elegantly simple, comprising key components to facilitate seamless interaction with both proprietary and open-source Large Language Models (LLMs).

Components:

  • FastAPI Restful API: At the core of the Sagify LLM Gateway lies a FastAPI-based Restful API, serving as the unified interface for all LLM interactions. This API acts as the entry point, handling requests and orchestrating communication with underlying LLM providers.

  • Proprietary LLM Integration: For users opting to leverage proprietary LLMs such as OpenAI, the unified API interface directly interacts with these services. This streamlined integration ensures smooth communication and interoperability with proprietary LLM providers.

  • Open-Source LLM Deployment: Alternatively, users may choose to utilize open-source LLMs. In this case, these models are deployed as AWS SageMaker endpoints on the AWS cloud infrastructure. The unified API interface seamlessly communicates with these SageMaker endpoints, enabling efficient utilization of open-source LLMs within the Sagify ecosystem.

By adopting this architectural approach, the Sagify LLM Gateway offers a flexible and adaptable solution, accommodating diverse LLM requirements while maintaining simplicity and efficiency in model interactions.

Getting started - LLM Deployment with no code

  1. Make sure to configure your AWS account by following the instructions at section Configure AWS Account

  2. Finally, run the following command:

sagify cloud foundation-model-deploy --model-id model-txt2img-stabilityai-stable-diffusion-v2-1-base --model-version 1.* -n 1 -e ml.p3.2xlarge --aws-region us-east-1 --aws-profile sagemaker-dev

You can change the values for ec2 type (-e), aws region and aws profile with your preferred ones.

Once the Stable Diffusion model is deployed, you can use the generated code snippet to query it. Enjoy!

All these lists of supported open-source models are supported on AWS Sagemaker and can be retrieved by running the command sagify llm models --all --provider sagemaker. If you want to focus only on chat completions models, then run sagify llm models --chat-completions --provider sagemaker. For image creations and embeddings, sagify llm models --image-creations --provider sagemaker and sagify llm models --embeddings --provider sagemaker, respectively.

Set up OpenAI

You need to define the following env variables before you start the LLM Gateway server:

  • OPENAI_API_KEY: Your OpenAI API key. Example: export OPENAI_API_KEY=....
  • OPENAI_CHAT_COMPLETIONS_MODEL: It should have one of values here or here.
  • OPENAI_EMBEDDINGS_MODEL: It should have one of values here.
  • OPENAI_IMAGE_CREATION_MODEL: It should have one of values here.

Set up open-source LLMs

First step is to deploy the LLM model(s). You can choose to deploy all backend services (chat completions, image creations, embeddings) or some of them.

If you want to deploy all of them, then run sagify llm start --all. This command will deploy all backend services (chat completions, image creations, embeddings) with the following configuration:

{
    "chat_completions": {
        "model": "llama-2-7b",
        "instance_type": "ml.g5.2xlarge",
        "num_instances": 1,
    },
    "image_creations": {
        "model": "stabilityai-stable-diffusion-v2-1-base",
        "instance_type": "ml.p3.2xlarge",
        "num_instances": 1,
    },
    "embeddings": {
        "model": "gte-small",
        "instance_type": "ml.g5.2xlarge",
        "num_instances": 1,
    },
}

You can change this configuration by suppling your own config file, then you can run sagify llm start -all --config YOUR_CONFIG_FILE.json.

It takes 15 to 30 minutes to deploy all the backend services as Sagemaker endpoints.

The deployed model names, which are the Sagemaker endpoint names, are printed out and stored in the hidden file .sagify_llm_infra.json. You can also access them from the AWS Sagemaker web console.

Deploy FastAPI LLM Gateway - Docker

Once you have set up your backend platform, you can deploy the FastAPI LLM Gateway locally.

In case of using the AWS Sagemaker platform, you need to define the following env variables before you start the LLM Gateway server:

  • AWS_ACCESS_KEY_ID: It can be the same one you use locally for Sagify. It should have access to Sagemaker and S3. Example: export AWS_ACCESS_KEY_ID=....
  • AWS_SECRET_ACCESS_KEY: It can be the same one you use locally for Sagify. It should have access to Sagemaker and S3. Example: export AWS_ACCESS_KEY_ID=....
  • AWS_REGION_NAME: AWS region where the LLM backend services (Sagemaker endpoints) are deployed.
  • S3_BUCKET_NAME: S3 bucket name where the created images by the image creation backend service are stored.
  • IMAGE_URL_TTL_IN_SECONDS: TTL in seconds of the temporary url to the created images. Default value: 3600.
  • SM_CHAT_COMPLETIONS_MODEL: The Sagemaker endpoint name where the chat completions model is deployed.
  • SM_EMBEDDINGS_MODEL: The Sagemaker endpoint name where the embeddings model is deployed.
  • SM_IMAGE_CREATION_MODEL: The Sagemaker endpoint name where the image creation model is deployed.

In case of using the OpenAI platform, you need to define the following env variables before you start the LLM Gateway server:

  • OPENAI_API_KEY: Your OpenAI API key. Example: export OPENAI_API_KEY=....
  • OPENAI_CHAT_COMPLETIONS_MODEL: It should have one of values here or here.
  • OPENAI_EMBEDDINGS_MODEL: It should have one of values here.
  • OPENAI_IMAGE_CREATION_MODEL: It should have one of values here.

Now, you can run the command sagify llm gateway --image sagify-llm-gateway:v0.1.0 --start-local to start the LLM Gateway locally. You can change the name of the image via the --image argument.

This command will output the Docker container id. You can stop the container by executing docker stop <CONTAINER_ID>.

Examples

(Remember to export first all the environment variables you need)

In the case you want to create a docker image and then run it

sagify llm gateway --image sagify-llm-gateway:v0.1.0 --start-local
 ```

 If you want to use just build the image
 ```{bash}
 sagify llm gateway --image sagify-llm-gateway:v0.1.0
 ```

If you want to support both platforms (OpenAI and AWS Sagemaker), then pass all the env variables for both platforms.

### Deploy FastAPI LLM Gateway - AWS Fargate

In case you want to deploy the LLM Gateway to AWS Fargate, then you can follow these general steps:

1. Containerize the FastAPI LLM Gateway: See previous section.
2. Push Docker image to Amazon ECR.
3. Define Task Definition: Define a task definition that describes how to run your containerized FastAPI application on Fargate. Specify the Docker image, container port, CPU and memory requirements, and environment variables.
4. Create ECS Service: Create a Fargate service using the task definition. Configure the desired number of tasks, networking options, load balancing, and auto-scaling settings.
4. Set Environment Variables: Ensure that your FastAPI application retrieves the environment variables correctly at runtime.

Here's an example CloudFormation template to deploy a FastAPI service to AWS Fargate with 5 environment variables:

```yaml

In a small bowl, whisk together the egg yolks and lemon juice or vinegar until well combined.\n2. Slowly pour in the oil while continuously whisking the mixture. You can do this by hand with a whisk or use an electric mixer on low speed.\n3. Continue whisking until the mixture thickens and emulsifies, which should take about 5-7 minutes. You'll know it's ready when it reaches a thick, creamy consistency.\n4. Taste and adjust the seasoning as needed. You can add more salt, pepper, or lemon juice to taste.\n5. Transfer the mayonnaise to a jar or airtight container and store it in the fridge for up to 1 week.\n\nThat's it! Homemade mayonnaise is a great way to control the ingredients and flavor, and it's also a fun kitchen experiment. Enjoy!"

            "url": "https://your-bucket.s3.amazonaws.com/31cedd17-ccd7-4cba-8dea-cb7e8b915782.png?AWSAccessKeyId=AKIAUKEQBDHITP26MLXH&Signature=%2Fd1J%2FUjOWbRnP5cwtkSzYUVoEoo%3D&Expires=1708779204"
        }
    ]
}

The above example returns a url to the image. If you want to return a base64 value of the image, then set response_format to base64_json in the request body params.

Upcoming Proprietary & Open-Source LLMs and Cloud Platforms

Machine Learning

Getting started - Custom Training and Deployment

Step 1: Clone Machine Learning demo repository

You're going to clone and train a Machine Learning codebase to train a classifier for the Iris data set.

Clone repository:

git clone https://github.com/Kenza-AI/sagify-demo.git 

Cd into the cloned repo:

cd sagify-demo

Create environment:

mkvirtualenv sagify-demo

Don't forget to activate the virtualenv after the creation of environment by executing workon sagify-demo.

Install dependencies:

make requirements

Step 2: Initialize sagify

sagify init

Type in sagify-demo for SageMaker app name, N in question Are you starting a new project?, src for question Type in the directory where your code lives and make sure to choose your preferred Python version, AWS profile and region. Finally, type requirements.txt in question Type in the path to requirements.txt.

A module called sagify_base is created under the src directory. The structure is:

sagify_base/
    local_test/
        test_dir/
            input/
                config/
                    hyperparameters.json
                data/
                    training/
            model/
            output/
        deploy_local.sh
        train_local.sh
    prediction/
        __init__.py
        nginx.conf
        predict.py
        prediction.py
        predictor.py
        serve
        wsgi.py
    training/
        __init__.py
        train
        training.py
    __init__.py
    build.sh
    Dockerfile
    executor.sh
    push.sh

Step 3: Integrate sagify

As a Machine Learning engineer, you only need to conduct a few actions. Sagify takes care of the rest:

  1. Copy a subset of training data under sagify_base/local_test/test_dir/input/data/training/ to test that training works locally
  2. Implement train(...) function in sagify_base/training/training.py
  3. Implement predict(...) function in sagify_base/prediction/prediction.py
  4. Optionally, specify hyperparameters in sagify_base/local_test/test_dir/input/config/hyperparameters.json

Hence,

  1. Copy iris.data files from data to sagify_base/local_test/test_dir/input/data/training/:
cp ./data/iris.data ./src/sagify_base/local_test/test_dir/input/data/training/
  1. Replace the TODOs in the train(...) function in sagify_base/training/training.py file with:
input_file_path = os.path.join(input_data_path, 'iris.data')
clf, accuracy = training_logic(input_file_path=input_file_path)

output_model_file_path = os.path.join(model_save_path, 'model.pkl')
joblib.dump(clf, output_model_file_path)

accuracy_report_file_path = os.path.join(model_save_path, 'report.txt')
with open(accuracy_report_file_path, 'w') as _out:
    _out.write(str(accuracy))

and at the top of the file, add:

import os

import joblib

from iris_training import train as training_logic
  1. Replace the body of predict(...) function in sagify_base/prediction/prediction.py with:
model_input = json_input['features']
prediction = ModelService.predict(model_input)

return {
    "prediction": prediction.item()
}

and replace the body of get_model() function in ModelService class in the same file with:

if cls.model is None:
    import joblib
    cls.model = joblib.load(os.path.join(_MODEL_PATH, 'model.pkl'))
return cls.model

Step 4: Build Docker image

It's time to build the Docker image that will contain the Machine Learning codebase:

sagify build

If you run docker images | grep sagify-demo in your terminal, you'll see the created Sagify-Demo image.

Step 5: Train model

Time to train the model for the Iris data set in the newly built Docker image:

sagify local train

Model file model.pkl and report file report.txt are now under sagify_base/local_test/test_dir/model/

Step 6: Deploy model

Finally, serve the model as a REST Service:

sagify local deploy

Run the following curl command on your terminal to verify that the REST Service works:

curl -X POST \
http://localhost:8080/invocations \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/json' \
-d '{
    "features":[[0.34, 0.45, 0.45, 0.3]]
}'

It will be slow in the first couple of calls as it loads the model in a lazy manner.

Voila! That's a proof that this Machine Learning model is going to be trained and deployed on AWS SageMaker successfully. Now, go to the Usage section in Sagify Docs to see how to train and deploy this Machine Learning model to AWS SageMaker!

Classic Machine Learning Usage

Push Docker Image to AWS ECR

If you have followed all the steps of Getting Started, run sagify push to push the Docker image to AWS ECR. This step may take some time depending on your internet connection upload speed.

Create S3 Bucket

Make sure to create an S3 bucket with a name of your choice, for example: sagify-demo

Upload Training Data

Execute sagify cloud upload-data -i data/ -s s3://sagify-demo/training-data to upload training data to S3

Train on AWS SageMaker

Execute sagify cloud train -i s3://sagify-demo/training-data/ -o s3://sagify-demo/output/ -e ml.m4.xlarge to train the Machine Learning model on SageMaker. This command will use the pushed Docker image.

Copy the displayed Model S3 location after the command is executed (example: s3://sagify-demo/output/sagify-demo-2018-04-29-15-04-14-483/output/model.tar.gz)

Deploy on AWS SageMaker

Execute sagify cloud deploy -m s3://sagify-demo/output/.../output/model.tar.gz -n 3 -e ml.m4.xlarge to deploy the model on SageMaker.

Call SageMaker REST Endpoint

Find the endpoint URL under Endpoints in AWS SageMaker service on AWS console. Please, refer to https://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-use-postman-to-call-api.html on how to call it from Postman as authorization is required.

Remember that it's a POST HTTP request with Content-Type application/json, and the request JSON body is of the form:

{
    "features":[[0.34, 0.45, 0.45, 0.3]]
}

Hyperparameter Optimization

Given that you have configured your AWS Account as described in the previous section, you're now ready to perform Bayesian Hyperparameter Optimization on AWS SageMaker! The process is similar to training step.

Step 1: Define Hyperparameter Configuration File

Define the Hyperparameter Configuration File. More specifically, you need to specify in a local JSON file the ranges for the hyperparameters, the name of the objective metric and its type (i.e. Maximize or Minimize). For example:

{
    "ParameterRanges": {
        "CategoricalParameterRanges": [
            {
                "Name": "kernel",
                "Values": ["linear", "rbf"]
            }
        ],
        "ContinuousParameterRanges": [
        {
          "MinValue": 0.001,
          "MaxValue": 10,
          "Name": "gamma"
        }
        ],
        "IntegerParameterRanges": [
            {
                "Name": "C",
                "MinValue": 1,
                "MaxValue": 10
            }
        ]
    },
    "ObjectiveMetric": {
        "Name": "Precision",
        "Type": "Maximize"
    }
}

Step 2: Implement Train function

Replace the TODOs in the train(...) function in sagify_base/training/training.py file with your logic. For example:

from sklearn import datasets
iris = datasets.load_iris()

# Read the hyperparameter config json file
import json
with open(hyperparams_path) as _in_file:
    hyperparams_dict = json.load(_in_file)

from sklearn import svm
clf = svm.SVC(
    gamma=float(hyperparams_dict['gamma']),  # Values will be read as strings, so make sure to convert them to the right data type
    C=float(hyperparams_dict['C']),
    kernel=hyperparams_dict['kernel']
)

from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(
    iris.data, iris.target, test_size=0.3, random_state=42)

clf.fit(X_train, y_train)

from sklearn.metrics import precision_score

predictions = clf.predict(X_test)

precision = precision_score(y_test, predictions, average='weighted')

# Log the objective metric name with its calculated value. In tis example is Precision.
# The objective name should be exactly the same with the one specified in the hyperparams congig json file.
# The value must be a numeric (float or int).
from sagify.api.hyperparameter_tuning import log_metric
name = "Precision"
log_metric(name, precision)

from joblib import dump
dump(clf, os.path.join(model_save_path, 'model.pkl'))

print('Training complete.')

Step 3: Build and Push Docker image

  1. sagify build Make sure sagify is in your requirements.txt file.
  2. sagify push

Step 4: Call The CLI Command

And, finally, call the hyperparameter-optimization CLI command. For example:

sagify cloud hyperparameter-optimization -i s3://my-bucket/training-data/ -o s3://my-bucket/output/ -e ml.m4.xlarge -h local/path/to/hyperparam_ranges.json 

Step 5: Monitor Progress

You can monitor the progress via the SageMaker UI console. Here is an example of a finished Hyperparameter Optimization job:

Hyperparameter Optimization Results

  • Then, go back the page of the Role you created and click on the Trust relationships tab:

Trust Relationship

  • Click on Edit trust relationship and add the following:
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
            "Effect": "Allow",
            "Principal": {
                "AWS": "PASTE_THE_ARN_YOU_COPIED_EARLIER",
                "Service": "sagemaker.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}
  • You're almost there! Make sure that you have added the IAM user in your ~/.aws/credentials file. For example:
[test-sagemaker]
aws_access_key_id = ...
aws_secret_access_key = ...
  • And, finally, add the following in the ~/.aws/config file:
[profile test-sagemaker]
region = us-east-1 <-- USE YOUR PREFERRED REGION
role_arn = COPY_PASTE_THE_ARN_OF_THE_CREATED_ROLE_NOT_USER! for example: arn:aws:iam::...:role/TestSageMakerRole
source_profile = test-sagemaker
  • That's it! From now on, choose the created AWS profile when initializing sagify.

  • You can change the AWS profile/region in an already initialized sagify module by changing the value of aws_profile/aws_region in .sagify.json.

This command retrieves a Docker image from AWS Elastic Container Service and executes it on AWS SageMaker in batch transform mode, i.e. runs batch predictions on user defined S3 data. SageMaker will spin up REST container(s) and call it/them with input data(features) from a user defined S3 path.

Things to do: - You should implement the predict function that expects a JSON containing the required feature values. It's the same predict function used for deploying the model as a REST service. Example of a JSON:

{
    "features": [5.1,3.5,1.4,0.2]
}
  • The input S3 path should contain a file or multiple files where each line is a JSON, the same JSON format as the one expected in the predict function. Example of a file:
{"features": [5.1,3.5,1.4,0.2]}
{"features": [4.9,3.0,1.4,0.2]}
{"features": [4.7,3.2,1.3,0.2]}
{"features": [4.6,3.1,1.5,0.2]}
