LEAP SDK (archived)

The LEAP SDK is deprecated. This archived reference is kept for teams still shipping it; new projects should use llama.cpp directly.

The LEAP SDK is deprecated and no longer receives new releases. It was a Kotlin Multiplatform wrapper around llama.cpp, and everything it provided is available from llama.cpp directly. New projects should follow the Build with llama.cpp guides; existing users can find a concept-by-concept mapping in Migrating from LEAP SDK.

Published LEAP SDK artifacts remain available (Swift Package Manager via Liquid4All/leap-sdk, Maven Central under ai.liquid.leap:*), but they are frozen at their last release and are not updated for new LFM checkpoints. Sampling defaults, chat templates, and tool-call parsing for current models are maintained upstream in llama.cpp.
