The Enigma of Closed Source LLMs: What Makes Them Tick?

Large language models (LLMs) are revolutionizing the way we interact with technology, but a key distinction exists between those readily available and those shrouded in secrecy: closed source LLMs. While the open-source world offers transparency and collaboration, closed source LLMs operate behind a veil of proprietary code. This raises questions about their inner workings and the implications for the wider AI landscape.

What is a closed source LLM?

Essentially, a closed source LLM is one whose underlying code and training data are not publicly available. This means that only the developers and their chosen partners have access to the inner workings of the model. In contrast, open-source LLMs allow anyone to inspect, modify, and even improve the code, fostering a vibrant community of developers and researchers.

The Defining Characteristic: Proprietary Code

The most defining characteristic of closed source LLMs is their proprietary code. This code is a closely guarded secret, carefully designed and optimized by the developers. The lack of transparency poses both challenges and opportunities:

Challenges:

• Lack of Auditability: Without access to the code, it's impossible to fully understand how the model arrives at its outputs. This lack of transparency raises concerns about potential bias, ethical implications, and the potential for misuse.
• Limited Customization: Users are restricted to the functionalities offered by the developers, with no ability to modify or extend the model's capabilities.
• Black Box Effect: The inner workings of closed source LLMs are essentially a "black box," making it difficult to diagnose problems, understand limitations, or even trust the model's outputs.

Opportunities:

• Competitive Advantage: Proprietary code can provide a competitive advantage, allowing companies to differentiate themselves and control access to their powerful AI technology.
• Improved Performance: Closed source development can potentially result in faster and more efficient models, as the developers can focus on optimizing the code without external contributions.
• Data Privacy and Security: Closed source LLMs can offer increased control over data security and privacy, as the code and data are not exposed to the public.

Examples of Closed Source LLMs:

• Google's LaMDA (Language Model for Dialogue Applications) - powering Google's conversational AI services.
• Meta's OPT (Open Pretrained Transformer) - initially open-source, but now also offered in a closed source version with additional features and capabilities.
• Microsoft's GPT-3 (Generative Pre-trained Transformer 3) - a powerful language model used in a wide range of applications.

Looking Ahead:

The debate between closed source and open source LLMs will likely continue. As AI technology evolves, understanding the implications of these approaches will be crucial. The future of AI may depend on finding a balance between innovation, transparency, and ethical considerations.
