Brainglue is a large language model experimental platform that allows anyone to build powerful prompt chains to solve complex generative AI problems. Brainglue provides an intuitive AI playground, making it easy to create and implement prompt chains. Users can experiment with different AI configurations by adjusting the context window and temperature settings. Brainglue supports various cutting-edge AI models such as GPT-3.5 and GPT-4, and plans to add more models soon. Users can define global variables and dynamically assign values for use in the prompt chains. Brainglue supports using AI's responses within a prompt chain to inform the next prompt, enabling more complex and reasonable outputs. Brainglue provides a template library for prompt chains, enhancing AI's reasoning capabilities.
