The AMD-aligned Lemonade open-source project, which functions as a local AI server, released version 2026.39.1 today and a release candidate for 2026.40. These updates introduce a new versioning scheme and address a significant issue with AMD APU model streaming. A key change in the latest Lemonade SDK is the removal of the OpenMOSS ROCm backend. This decision was made because the OpenMOSS ROCm implementation was found to be approximately "40x slower than Vulkan" for AI inference tasks. By streamlining its backend strategy and focusing on more performant options, Lemonade aims to improve efficiency for users.
