LangSmith has introduced dynamic few-shot example selectors to enhance the performance of applications using large language models (LLMs) through a technique called few-shot prompting. This approach involves using a small set of examples to guide the model, and dynamically selecting the most relevant examples based on user input to improve efficiency and personalization. Unlike static few-shot prompting, which uses a fixed set of examples, dynamic prompting adjusts the examples in response to user needs, avoiding the complexity and limitations of fine-tuning. LangSmith allows users to easily curate, index, and search datasets, enabling rapid iterations and personalized applications without requiring extensive infrastructure or expertise. The dynamic few-shot prompting feature is currently in closed beta, with plans for a public launch soon, and is designed to streamline dataset management and refine LLM app performance.
