AI Toolkit for Visual Studio Code provides a dedicated environment for developers to build, test, and deploy AI applications directly within their preferred code editor. This extension simplifies the complex workflow of AI development, offering a suite of tools tailored for large language models (LLMs) and small language models (SLMs). Developers can experiment with different models in the integrated model playground, refining their prompts through advanced prompt engineering features. The toolkit supports batch evaluation, allowing for efficient testing and comparison of model performance across multiple inputs. For those looking to optimize model behavior, fine-tuning capabilities are available, enabling custom adjustments to pre-trained models. Furthermore, its multi-modal support means developers can work with various data types beyond just text, expanding the scope of their AI projects. With AI Toolkit for Visual Studio Code, developers gain a cohesive and productive workspace, significantly accelerating the iteration and deployment cycles for their AI-powered solutions. It transforms Visual Studio Code into a powerful hub for creating sophisticated AI applications, from initi
