Describe the problem

The iOS GenAI inference engine source code (mediapipe/tasks/ios/genai/ and mediapipe/tasks/cc/genai/inference/) is not included in the open-source repository. The CocoaPods for MediaPipeTasksGenAI and MediaPipeTasksGenAIC are published as prebuilt binaries built internally by Google.

Complete Logs

The iOS GenAI inference engine source code (mediapipe/tasks/ios/genai/ and mediapipe/tasks/cc/genai/inference/) is not included in the open-source repository.

The CocoaPods for MediaPipeTasksGenAI and MediaPipeTasksGenAIC are published as prebuilt binaries built internally by Google.

This makes it impossible to:

• Build GenAI/GenAIC frameworks from source
• Distribute them via Swift Package Manager (SPM)
• Customize or debug the inference engine

The build script (build_ios_framework.sh) already supports GenAI/GenAIC framework names and references targets like MediaPipeTasksGenAI_framework and MediaPipeTasksGenAI_library, but these targets don't exist in the public mediapipe/tasks/ios/BUILD. The GenAIC section is even marked as "This section is for internal purposes only" with a guard on ENABLE_ODML_COCOAPODS_BUILD.

Other platforms (Android/Java, Python, Web) have their GenAI implementations available in the repo. Could the iOS layer be open-sourced as well?

Missing directories/files in the public repo:

• mediapipe/tasks/ios/genai/ (Swift layer - LlmInference.swift, etc.)
• mediapipe/tasks/cc/genai/inference/ (C++ layer - llm_inference_engine.h, etc.)

Missing BUILD targets in mediapipe/tasks/ios/BUILD:

• MediaPipeTasksGenAI_framework
• MediaPipeTasksGenAI_library

Hi @mihaidimoiu,

The GenAI task in MediaPipe has been deprecated, as noted in the official documentation. We kindly request that you migrate to LiteRT-LM.
