Create your virtual team by using curated AI agents and even add your own. Use external tools to expand your AI interactions, such as generating images. Try visual input across multiple models to compare and improve. One-stop place to use LLMs in assistant mode and playground mode. Save your most frequently used prompts into library and use them at any time. Large Language Models (LLMs) have powerful reasoning capabilities, but their outputs are diverse and unpredictable. For generative AI applications to deliver value and competitiveness in vertical domains, they must efficiently and excellently handle similar tasks and scenarios. If this instability cannot be reduced to an acceptable level, the user experience will be impacted, and the product will lose its competitive edge. To ensure product stability and reliability, development teams need to thoroughly evaluate the models and prompts used during the development process.
