runanywhere_mlx 0.20.9

Apple MLX backend for RunAnywhere Flutter SDK with on-device LLM, VLM, embeddings, speech recognition, and speech synthesis.

RunAnywhere MLX for Flutter

Optional Apple MLX backend for the RunAnywhere Flutter SDK. The package uses the canonical Swift RunAnywhereMLX runtime and supports LLM, VLM, embedding, speech-recognition, and speech-synthesis models on physical iOS 17.5 or newer devices. The arm64 iOS Simulator slice is provided only for package, compile, link, and startup validation; MLX registration returns false there.

The iOS plugin intentionally uses CocoaPods. Its precompiled Hub/Crypto dependencies look for named bundles at the application root, and CocoaPods preserves that required layout without introducing SwiftPM module collisions.

Requirements

• Flutter 3.44+
• Xcode 26+ with the Swift 6.2 toolchain
• A physical Apple device running iOS 17.5+ for MLX execution

dependencies:
  runanywhere: ^0.20.9
  runanywhere_mlx: ^0.20.9

Register the backend before initializing the core SDK:

import 'package:runanywhere_mlx/runanywhere_mlx.dart';

final mlxRegistered = await MLX.register();

MLX.register() is idempotent and returns false when the runtime is not available. Model registration, download, loading, and inference use the normal RunAnywhere core APIs.
