FIT: An enterprise-grade AI development framework providing a multilingual function engine (FIT), a streaming orchestration engine (WaterFlow), and a Java-ecosystem alternative to LangChain (FEL). It supports native and Spring dual-mode operation, hot-pluggable plugins, intelligent distributed deployment, and seamless integration of large models with business systems.
FIT is an enterprise AI development framework with a multilingual function engine, a flow orchestration engine, and Java tools for connecting language models, knowledge bases, and external tools. It is for Java-oriented teams building AI applications that can run locally or in distributed deployments with plugins. The catalogue add-ons provide commands, skills, instructions, and settings for working with FIT.
