LemonSeed Studio

An editor and IDE for iPad with on-device LLM inference on an AMD GPU.

LemonSeed Studio is a single iPad app. It bundles:

• mac_linuxgpu: the unmodified upstream Linux amdgpu + amdkfd driver, embedded in the app as a PCIDriverKit extension. It drives an AMD GPU in a Thunderbolt enclosure.
• LemonSeed Engine: the inference engine, running on that GPU through its HSA runtime and HRX/Loom.
• amdgpu_mtopg: live GPU telemetry.

git clone --recurse-submodules <repository>

Or, in an existing clone:

git submodule update --init

mac_linuxgpu fetches its own pinned Linux sources sparsely on first build, so its nested kernel submodule does not need to be cloned recursively.

The original code is available under MIT or GPL-2.0-only, at your option. See LICENSE. Bundled and submodule components keep their own licenses; see THIRD_PARTY.md.
