No Clocks

Impact of AI on Developer Productivity: Faster development cycles: Code suggestions and automation reduce time spent on repetitive tasks. Improved code quality: AI tools identify bugs or security risks that may go unnoticed by manual reviews. Enhanced learning: Engineers can receive real-time feedback or even ask AI for code explanations to learn new patterns or frameworks.

GitHub Copilot is a game-changer for writing code. Powered by OpenAI’s Codex model, Copilot suggests lines of code based on the context of what you’re writing. It’s especially useful when you’re working with repetitive tasks or writing boilerplate code.

ChatGPT, an AI chatbot developed by OpenAI, is not just a tool for casual conversations. It can be used to ask technical questions, explain difficult code, or even generate ideas for solving specific coding problems. Developers often use it for quick consultations — whether it’s about debugging or understanding the intricacies of a particular algorithm.

AI-Assisted System Architecture and Design As AI becomes more sophisticated, it may start to play a role in designing system architectures. Currently, system design is one of the more complex tasks that engineers handle, requiring a deep understanding of the trade-offs between different architectural patterns (monolithic vs. microservices, synchronous vs. asynchronous communication, etc.). Future AI tools could help design optimal architectures by analyzing the specific needs of a project, performance goals, and scalability requirements. AI could suggest which patterns, frameworks, or technologies are best suited for a given application. It could even generate architecture diagrams, API designs, or database schemas based on historical data from similar projects. This would revolutionize system design, making it faster and more accessible to engineers of all levels. While experienced architects would still be needed to make judgment calls, AI could drastically reduce the time spent on initial design phases, especially in large and complex systems.

Both OpenAI programing guide and Anyscale Endpoints blog [7] distill down to simple steps: Call the model with the user query and a list of functions defined in the Chat Completions API parameter as tools. The model can choose to call one or more functions; if so, the content will be a stringified JSON object adhering to your custom schema. Parse the string into JSON in your code, and call your function with the provided arguments if they exist. Call the model again by appending the function response as a new message, and let the model summarize the results back to the user. Following the above simple steps, our user_content to the LLM generates three required parameters (location, latitude, longitude) as a JSON object in its response.

Examples and Use Cases of Function Calling in LLM

Apart from the above use cases mentioned in the Open AI programming guide [10], Ben Lorica visually and comprehensively captures use cases of general function calling in LLMs, including the OpenAI Assistant Tools API [11]. Lorica succinctly states that early use cases include applications such as customer service chatbots, data analysis assistants, and code generation tools. Other examples extend to creative, logistical, and operational domains: writing assistants, scheduling agents, summarizing news., etc.
