In the current era marked by AI and the deployment of ChatGPT models, the integration of OpenAI models with Natural Language Processing (NLP) techniques remains essential, and Azure services serve as pivotal components of this synthesis.

The multiclass classification problem is a challenge that any data scientist would eagerly embrace. When you add the factor of classifying text in the Serbian language, a true research adventure is on the horizon.

Of course, neural networks are indispensable in solving this problem - LSTM NN (Long Short-Term Memory Neural Networks) plays a significant role. Still, there is also the FastText library, Serbian spellchecker, OpenAI text recovery, and many other methods we have employed to achieve the desired result of over 95% classification accuracy.

For the efficient implementation of the holistic solution and the alleviation of concerns related to performance, Azure Machine Learning Studio and Azure Synapse Studio have been instrumental, serving as the final, integrative elements of this intricate puzzle. These Azure services streamline the implementation process, ensuring the seamless orchestration of the entire solution.
