Navigating The Evolutions in GPT 3.5 Turbo

Lessons from Model Variations: 0301 -> 0613

If you’ve been using OpenAI’s GPT 3.5 Turbo model, you’re likely aware that there have been some changes between different versions of the model. An example of this can be seen when comparing the GPT Turbo 3.5 model 0301 with the more recent 0613 model. While both belong to the same family, they have different ways of interpreting and responding to prompts, leading to divergent outcomes that can drastically affect the utility of the model in certain use cases.

Unpacking the Differences

In our use case, we can imagine a scenario where an application uses the GPT model to process German news articles. It calls the model to perform a series of translations and simplifications: starting with a direct English translation, moving to a simplified A1 German version, followed by its English translation, then a simplified B1 German version, and its corresponding English translation.

In the context of this workflow, the 0301 model performs admirably. It consistently follows prompts, delivering reliable results across a variety of input articles. However, with the 0613 update, the output takes a disappointing turn. Instead of closely adhering to the prompt, the model diverges from expectations, producing results that are not usable for the application’s purpose.

Digging Deeper

From the outside, this disparity between the two versions may seem perplexing, considering they both are iterations of the GPT 3.5 Turbo. The explanation lies in how the newer version interacts with system prompts. In the 0613 model, the algorithm has been fine-tuned to follow the system prompt more aggressively. This change can lead to unexpected results if the model is used with the same prompts optimized for the 0301 version.

In some cases, introducing a “persona” prompt might resolve this issue. For instance, by prompting the system with: “You are a veteran German and English translator, you will follow A1 and simplified B1 protocols when requested.” However, this isn’t a silver bullet, and users might still find the newer model doesn’t perform as well as the older version for their specific application.

Embracing the Change

So, what can be done? How can developers adapt to these changes in the GPT model and ensure their applications continue to function as expected?

  • Detailed Persona Prompts: Using detailed persona prompts can help guide the model to behave in a specific manner. However, this requires careful crafting of the prompt to encapsulate all desired behaviors.
  • Prompt Experimentation: Developers should be prepared for a certain degree of experimentation. The changes in how the model interacts with prompts mean that developers might need to revisit and revise their prompts to ensure they’re obtaining the desired output.
  • Change Management: Lastly, a change management plan should be in place. With new versions of the model being released periodically, developers need to be prepared to adapt their applications to the evolving capabilities and behaviors of the models.

While the changes in GPT 3.5 Turbo’s different versions may pose a challenge, they also provide an opportunity. Developers can explore new ways of interacting with the model and possibly discover innovative uses for this powerful language model. With prompt experimentation and careful change management, they can continue to harness the power of AI, regardless of the version they are using.
