Why New AI Models Aren’t Always Better

In this post we explore the importance of evaluating new AI technologies within specific contexts and the value of established, reliable models for long-term success.

In the fast-paced world of Artificial Intelligence (AI), new models constantly promise improved performance and efficiency. While it's tempting to quickly adopt these cutting-edge technologies, a more prudent approach involves carefully evaluating their practical benefits within specific contexts. Rushing to embrace the latest AI models can lead to unnecessary risks and suboptimal results.

Our experiences in the AI industry tells us that adopting the latest models should be tempered with a thorough evaluation of their actual performance. By examining the challenges and considerations that come with integrating new AI models into existing systems, we can gain valuable insights into the importance of a measured approach to AI adoption.

New Models: A Cautionary Tale

New AI models often generate excitement due to their promise of enhanced capabilities at a lower cost. However, initial feedback suggests that their performance may not be as universally superior as anticipated. While new models may excel in general scenarios, they may not outperform older, more refined models in specific tasks.

A prime example of this is the well-known case of GPT-4, a state-of-the-art language model. Despite bearing the same name across iterations, GPT-4 underwent continuous fine-tuning, which introduced unpredictability in its performance. Later generations of GPT-4 were observed to perform worse at specific tasks compared to their predecessors. This highlights that even within the same model family, newer versions may not always guarantee improved results across all applications.

Moreover, newer models often face scalability challenges, requiring months of internal fine-tuning to reach optimal performance in production environments. During this period, nearly all new model releases have been met with instability issues. This problem is not unique to OpenAI; other platform providers such as AWS and Groq also face similar challenges. Newer models are often heavily capped, limiting their token production or request consumption during inference, which can hinder their adoption and usability in production systems.

Model providers may push for wider adoption to encourage use and gather feedback, which helps improve the models over time. However, for organizations deploying AI in production systems, this approach may not be the most suitable starting point for all applications. The instability and limitations associated with newer models can lead to suboptimal performance and increased operational costs.

Furthermore, the rapid pace of AI development means that newer models can quickly become outdated, potentially leading to a constant cycle of adoption and replacement. This is where open source plays a vital role. While the data used to train the models may not be openly available, having access to the model weights allows developers to preserve specific generations of models. This is crucial for predictability and long-term stability. It is entirely possible that many systems in the future will continue to use models produced a decade ago simply because developers are more accustomed to their behavior and performance. Open source ensures that these proven models remain accessible and usable, even as the AI landscape continues to evolve.

The Value of Established Systems

Well-established AI systems have undergone extensive testing and refinement, ensuring their robustness and reliability in real-world applications. They have been battle-tested in various scenarios and have demonstrated their ability to deliver consistent results. The narrative surrounding AI updates serves as a reminder that real advancement in AI lies in the careful evaluation and application of these technologies within specific contexts.

While newer models may offer potential advantages, their unproven nature can introduce risks and uncertainties that can outweigh any perceived benefits. The pursuit of innovation should be tempered with a pragmatic assessment of the real-world performance, scalability, and reliability of new AI models. Established systems provide a level of predictability and stability that is essential for mission-critical applications.

A balanced approach that considers the proven efficacy of existing solutions alongside the potential of newer models is essential. By prioritizing the use of tried and tested models, organizations can ensure a more stable and predictable AI performance. They can benefit from the accumulated knowledge and best practices associated with these established systems, reducing the risk of unexpected failures and ensuring a smoother implementation process.

Conclusion

Ultimately, the decision to integrate new AI models should be driven by a thorough assessment of their practical benefits, scalability, and ability to deliver reliable, consistent performance. Leveraging open source and sticking with proven models can provide a solid foundation for long-term AI success. Organizations must carefully weigh the benefits and risks associated with adopting new technologies, ensuring they align with their specific requirements and goals.
