How to Integrate GPT-3 AI in App

So now let's get to the integration of GPT-3 AI in the application. We define step-by-step process with all the details.

Familiarize yourself with different types of Open AI models

types of open ai models, gpt3 integration

Open AI offers several options. Models like "GPT-3" and "GPT-4" are language models capable of generating human-like text and providing detailed prompt responses. These models excel at answering questions or generating coherent and contextually relevant text.

For example, Open AI provides a model capable of transforming speech into text - Whisper. You can pass audio files to the API, transcribing the spoken content into text. It's particularly useful for businesses that convert voice-based interactions, such as customer orders or interview conversations, into textual data for further processing and analysis.

Open AI also has a model that specializes in working with images - DALL·E. These models enable you to perform various tasks, including image recognition, object detection, and other image-related operations.

Index your data for integration

indexing data gpt3 integration openai

When it comes to integrating Open AI into your system, indexing your data plays a crucial role. To provide meaningful interactions with the AI models, you need to provide them context. But what exactly does context mean in this context? It refers to the information you provide as prompts to the models. You can craft prompts in different ways and scenarios, allowing you to set the stage for the AI's response. For instance, you can place the model in a specific role to obtain relevant answers or seek guidance on proper organization documentation. By framing your queries and prompts appropriately, you can ensure more targeted and accurate responses.

To facilitate this integration and context-building process, a key concept to understand is embedding. It allows you to convert your data into a vector format, which can then be used in vector databases, forming a contextual foundation.

To understand embedding, let's take the example of Shazam. When Shazam identifies a song, it searches for a common denominator between its database and the audio it's analyzing. It converts the audio into a specific format, reducing it to a standardized representation. This process of reducing data to a common denominator is what embedding is all about. Just as you can embed audio, you can also embed text, music, or even images.

There are various vector databases available today, such as Pinecone, which excels at generating vector databases for efficient searching and matching. By indexing your data using embedding techniques and leveraging vector databases like Pinecone, you create a powerful foundation for integrating Open AI into your system. This enables the AI models to understand the context of your queries and prompts.

Data integration into vector database

When integrating your data into a vector database, it's important to understand that it operates differently from a traditional database like MongoDB with collections. Let's delve into the details of vector databases and how data integration works in this context.

Imagine we have business data, such as orders or product descriptions. From this data, we generate plain text strings. These strings are then processed using embedding models, which convert them into a vector format that can be understood and compared by the database. In essence, embedding takes the ordinary text and translates it into a standardized vector representation. The vectors derived from our data are then integrated into the vector database using open-source tools.

Now, when you make a query, you need to transform it into a vector format. This is where the integration with Open AI API comes into play. You specify the model and guide it to convert the input into the desired format.

The process typically involves leveraging an open-source NLP package to perform the embedding. We convert our data into vectors using the specified model. These vectors are not the only items added to the database.

During the indexing stage, convert our product or business data into a unified format suitable for integration. To achieve this, write a script that crosses our data and applies the embedding process using open-source tools like OpenAI's API. This involves converting each item through the embedding model, such as text-embedding-ada-002 from OpenAI, resulting in an array of elements with specific numerical values representing the vectors. These vectors contain valuable information about the items in a standardized format.

Once the data is indexed, we can query the vector database using prompts or questions. Just like asking the store employee for guidance, we provide a question or prompt to the system, which retrieves the relevant vectors from the database. The system then matches the query to the vectors and retrieves the desired information based on its understanding of the vectors and the stored data.
