Open Source Licenses - Playground for LM

1. Purpose of This Page

This page lists the third-party open-source components that are distributed with, or used to build features in, the current App Store release of Playground for LM. It also distinguishes Apple system frameworks, third-party models, third-party platforms, and brand identifiers from app-bundled open-source components.

2. Open-Source Components Distributed With the App

llama.cpp / ggml runtime components: The app integrates ThirdParty/llama.cpp/llama.xcframework for local GGUF inference and calls it through local bridge code such as LocalLLMBridge and LocalLLMEngine. Upstream project: https://github.com/ggml-org/llama.cpp. License: MIT License. Copyright notice: Copyright (c) 2023-2026 The ggml authors.
whisper.cpp / ggml runtime components: The app integrates the local speech-recognition runtime through ThirdParty/whisper.cpp and related local bridge code to read Whisper ggml models and perform speech-to-text on device. Upstream project: https://github.com/ggml-org/whisper.cpp. License: MIT License. Copyright notice: Copyright (c) 2023-2026 The ggml authors.
MLX Swift / MLX Swift LM: The app integrates parts of the MLX model runtime, language-model, and vision-language-model adapters through Swift Package dependencies to support compatible MLX directory models. Upstream projects: https://github.com/ml-explore/mlx-swift and https://github.com/ml-explore/mlx-swift-lm. License: MIT License. Copyright notices: Copyright (c) 2023 ml-explore; Copyright (c) 2024 ml-explore.
Hugging Face Swift packages: The app uses Swift packages such as swift-huggingface, swift-transformers, and swift-jinja to help process model directories, model configuration, tokenizer behavior, and template rendering. License: Apache License 2.0. Copyright notices are governed by Hugging Face SAS and the corresponding upstream project files.
Apple Swift packages: The app directly or indirectly uses Swift packages such as swift-collections, swift-numerics, swift-system, swift-syntax, swift-nio, swift-crypto, swift-asn1, and swift-atomics. License: Apache License 2.0; some packages include NOTICE files. Copyright notices are governed by each upstream project.
EventSource: The app may use EventSource through Swift Package dependencies to handle server-sent event streaming responses. Upstream project: https://github.com/mattt/EventSource. License: MIT License. Copyright notice: Copyright 2025 Mattt.
yyjson: The app may use yyjson through the dependency graph for high-performance JSON processing. Upstream project: https://github.com/ibireme/yyjson. License: MIT License. Copyright notice: Copyright (c) 2020 YaoYuan.
KaTeX: The app includes LMPlaygroundUI/KaTeX/katex.min.js, katex.min.css, contrib/auto-render.min.js, and font resources in fonts/ for LaTeX rendering. The bundled local files identify the version as 0.16.47. Upstream project: https://github.com/KaTeX/KaTeX. License: MIT License. Copyright notice: Copyright (c) 2013-2020 Khan Academy and other contributors.

3. Apple System Frameworks

The app uses Apple platform frameworks such as SwiftUI, Foundation, UIKit, UniformTypeIdentifiers, Darwin, WebKit, Network, and Combine. These frameworks are provided by the Apple SDK and are governed by Apple developer agreements, system licenses, and platform rules. They are not separate third-party open-source dependencies disclosed by this page.

4. Third-Party Models, Platforms, and Brand Identifiers

The app may display or link to names such as Qwen, Gemma, DeepSeek, Phi, NVIDIA Nemotron, GPT-OSS, Whisper, OpenAI, Claude, Gemini, LM Studio, Ollama, llama.cpp, LocalAI, and ModelScope only to identify model sources, model families, API connection methods, or compatible formats. The App Store release does not use official logos from those third-party models or platforms. Visual model marks in the app are app-owned neutral text badges. These names, model weights, API services, trademarks, download pages, and model licenses are not open-source components of the app and do not mean the developer owns, controls, or sublicenses the corresponding third-party model weights, API services, trademarks, or platform content.

Before downloading, importing, or running a third-party model, users should review the corresponding model page, model license, acceptable use policy, platform terms, and applicable laws. References to names or links are for source identification or compatibility purposes only and do not imply official cooperation, authorization, endorsement, agency, distribution, affiliation, or joint operation.

5. App-Owned Code and Assets

Except for the open-source components and third-party identifiers described above, the app's Swift / Objective-C++ bridge code, interface code, app icon, launch image, app-owned logo, copy, layout, diagnostics logic, and product experience are owned or controlled by the developer and are not licensed to users under an open-source license unless expressly stated otherwise.
