Semantix GenAI Serve

Semantix GenAI Serve is a library designed for users of Semantix GenAI Hub to create their own servers running AI models. This library provides an easy-to-use interface for serving AI models using the scalable infrastructure of Semantix GenAI Hub.

Features

• Easy integration with Hugging Face Transformers models
• Support for serving Seq2Seq models
• Customizable server settings
• Built-in support for GPU acceleration

Installation

To install the Semantix GenAI Serve library, run the following command:

pip install semantix-genai-serve

Usage

Basic Example

Here's a simple example of how to use the Semantix GenAI Serve library to serve a Hugging Face Transformers model:

from semantix_genai_serve import SemantixTorchKserve
from semantix_genai_serve.huggingface import ServeAutoSeq2SeqLM

class MyModel(ServeAutoSeq2SeqLM):
    def predict(self, payload, headers):
        # Implement your custom inference logic here
        pass

model = MyModel(checkpoint="facebook/bart-large-cnn")
model.start_server()

Customizing Server Settings

You can customize the server settings by passing additional arguments to the SemantixTorchKserve constructor:

model = MyModel(
    checkpoint="facebook/bart-large-cnn",
    name="my_model",
    base_cache_dir="/path/to/cache",
    force_local_load=True
)

• name: The name of the predictor (default: "predictor")
• base_cache_dir: The base directory for caching models (default: "/mnt/models"). Do not change that when deploying to Semantix GenAI Hub.
• force_local_load: If set to True, the model will be loaded from the local cache directory instead of downloading from Hugging Face's model hub (default: False). Do not change that when deploying to Semantix GenAI Hub.

Implementing Custom Inference Logic

To implement custom inference logic, you need to override the predict method in your model class:

class MyModel(ServeAutoSeq2SeqLM):
    def predict(self, payload, headers):
        # Implement your custom inference logic here
        input_example = payload["input_example"]
        # do something for inference
        # your output must be a dictionary so it gets automatically converted to JSON
        return {"response": "output"}
