Custom Wrappers

A "custom wrapper" in the context of large language models (LLMs) is a piece of code or software layer built specifically to interact with an LLM, tailoring its functionality to a particular use case by adding extra features, filtering outputs, or managing specific data formats, essentially providing a customized interface to access the LLM's capabilities beyond the standard API provided by the model itself. 

Key points about custom LLM wrappers:

  • Abstraction layer:

    They act as a middle ground, hiding the complexities of the underlying LLM and offering a simpler way for developers to integrate it into their applications. 

  • Customization for specific needs:

    By creating custom wrappers, developers can adjust the LLM's behavior to fit their unique requirements, such as enforcing specific tone of voice, applying domain-specific knowledge, or filtering potentially sensitive outputs. 

  • Enhancements and features:

    Wrappers can add functionalities like context management, prompt engineering techniques, memory capabilities, or data pre-processing to optimize the LLM's performance for a specific task. 

Example scenarios where custom wrappers are useful:

  • Industry-specific applications:

    A healthcare company might create a wrapper to ensure medical language is used accurately when interacting with an LLM. 

  • Brand voice consistency:

    A marketing team could design a wrapper to control the tone and style of text generated by an LLM to align with their brand identity. 

  • Data privacy concerns:

    A wrapper could be built to anonymize or redact sensitive information before feeding it to an LLM. 

Popular frameworks for creating custom LLM wrappers:

  • LangChain: A widely used Python library that provides a flexible framework for building LLM applications, allowing users to create custom wrappers for different LLMs and easily integrate them into their projects.
