LOGYCA public libraries: To interact with ChatGPT and analyze documents, files and other functionality of the OpenAI library.

Source code | Package (PyPI) | Samples

To interact with the examples, keep the following in mind

FastAPI example. Through Swagger, you can:

• https://github.com/logyca/python-libraries/tree/main/logyca-ai/samples/fastapi_async
• Use the example endpoints to obtain the input schemas for the post method and interact with the available parameters.
• Endpoint publishing is asynchronous of openai SDK.
• The model currently used is ChatGPT-4o, no other models have been tested so far.
• Currently the formats supported to receive files and extract the text to interact with artificial intelligence are: txt, csv, pdf, images, Microsoft (docx, xlsx).

Script example. Through of code, you can:

• https://github.com/logyca/python-libraries/tree/main/logyca-ai/samples/script_app_sync
• Examples shared with the example written in FastAPI.
• The examples use synchronous functionality of openai SDK.
• The model used is ChatGPT-4o for testing.

Environment variables documentation for example: fastapi_async

The examples are built in the Microsoft Azure OpenAI environment, and the variables to use are the following:

.env.sample

# Environment variables documentation:

# API_KEY:
# The general API key used for authentication with services. This key is typically used for accessing cloud-based or other API-driven platforms. Replace '***' with the actual key.

# AZURE_OPENAI_DEPLOYMENT:
# The name or identifier of the OpenAI deployment within Azure. This defines the specific model version and configuration you are using in Azure OpenAI Service. Set this to the name of the deployed model, such as 'chatgpt3.5-turbo-1106'.

# AZURE_OPENAI_ENDPOINT:
# The base URL of the Azure OpenAI Service endpoint. This is the URL where API requests are sent, typically formatted like 'https://<your-endpoint>.openai.azure.com/'.

# AZURE_OPENAI_MODEL_NAME:
# The name of the specific OpenAI model being used in Azure, for example, 'gpt-35-turbo'. This identifies which model variant will be used for processing requests.

# AZURE_OPENAI_MODEL_VERSION:
# The version of the OpenAI model deployed in Azure. This typically reflects updates or optimizations to the model, such as '1106' to indicate a version from November 6th.

# OPENAI_API_KEY:
# The API key provided by OpenAI directly (not through Azure). This is used to authenticate and access OpenAI services outside of Azure.

# OPENAI_API_VERSION:
# The version of the OpenAI API being used. This specifies the version of the API and its capabilities, for example, '2023-03-15-preview'. It dictates the available features and request format.

API_KEY=***
AZURE_OPENAI_DEPLOYMENT=***
AZURE_OPENAI_ENDPOINT=***
AZURE_OPENAI_MODEL_NAME=***
AZURE_OPENAI_MODEL_VERSION=***
