# 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.

<Warning>
  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](/deployment/on-device/llama-cpp/mobile) guides; existing users can find a concept-by-concept mapping in [Migrating from LEAP SDK](/deployment/on-device/llama-cpp/migrating-from-leap-sdk).
</Warning>

Published LEAP SDK artifacts remain available (Swift Package Manager via [`Liquid4All/leap-sdk`](https://github.com/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.

## Archived reference

These pages document the final LEAP SDK release (v0.10.x) and are no longer maintained.
