The world of AI is buzzing with large language models like ChatGPT's GPT-4o, which seem to hold vast amounts of information. But what if a company wants to use a model with its own proprietary data or specialized knowledge not found on the internet? Building a model from scratch or using a small, open-source one might seem like the only options. However, there's a more efficient way: custom AI.

Custom AI allows businesses to start with an existing model like GPT-4o and build upon it. This approach offers several advantages. First, it improves the quality of responses by fine-tuning the model to address specific weaknesses. Second, it can reduce costs by achieving high-quality results with a lower-cost model. This method is not just theoretical; it's already being put into practice.

For instance, Microsoft has applied this technique across its tech stack. GitHub Copilot and Nuance DAX are examples of tools that have been fine-tuned with specialized knowledge. DAX Copilot, for example, has seen significant adoption in healthcare, surpassing two million monthly physician-patient encounters. This success is due to the model's ability to produce accurate medical records by fine-tuning to specific data.

So, how can companies get started with custom AI? The first step is to identify where the current model falls short. Collect data on these weaknesses and use it to customize the model. This process requires high-quality, accessible, and secure data. Companies may need to invest in developing the skills to handle this data and apply the necessary techniques.

Custom AI also raises ethical considerations. Companies must ensure their applications behave responsibly, considering the potential implications of how the application will be used. Microsoft offers tools like Azure AI Content Safety to help customers build responsible AI systems. These tools address concerns around bias, fairness, and transparency, providing a comprehensive approach to AI risk mitigation.

The future of AI is moving towards agents that perform tasks autonomously. These agents will reimagine business processes, transforming how work gets done. Companies need to think critically about their customization strategy to ensure they are building the highest-quality, best-performing applications at the best price.

In conclusion, custom AI offers a practical way for businesses to leverage AI models tailored to their specific needs. By fine-tuning existing models, companies can improve response quality, reduce costs, and stay ahead in the rapidly evolving AI landscape.
