An SDK is a collection of tools, libraries, and documentation that helps developers build or extend AI applications. It provides everything needed to integrate with APIs, build custom features, or embed AI into enterprise workflows without starting from scratch.
A well-designed SDK reduces the engineering effort required to adopt an AI platform and allows development teams to focus on application logic rather than infrastructure plumbing. The quality of the SDK often determines how quickly a team can build something useful and how much ongoing maintenance it requires.
