1. Bundled open-source components requiring attribution

Nyx AI incorporates the following components under the Apache License 2.0. Their licences and any upstream NOTICE files are retained; their use here does not imply endorsement by their authors:

• pdf-parse (Apache-2.0): PDF text/image extraction.
• pdfjs-dist (Apache-2.0): Mozilla's PDF.js. Copyright (c) Mozilla Foundation.
• Puppeteer / puppeteer-core (Apache-2.0): (c) Google LLC.
• @puppeteer/browsers, chromium-bidi, webdriver-bidi-protocol (Apache-2.0): (c) The Chromium Authors. Puppeteer's browser-management and WebDriver BiDi support libraries.
• b4a, bare-events, bare-fs, bare-os, bare-path, bare-stream, bare-url, text-decoder, events-universal (Apache-2.0): (c) Holepunch. The "bare" runtime utilities, pulled in transitively via Puppeteer.
• crc-32 (Apache-2.0): (c) SheetJS LLC. Pure-JS CRC-32.
• detect-libc (Apache-2.0): (c) Lovell Fuller and contributors. C standard library detection.
• readdir-glob (Apache-2.0): (c) Yann Armelin. Recursive readdir with glob filtering.
• tunnel-agent (Apache-2.0): (c) Mikeal Rogers. HTTP proxy tunnelling agent.
• DOMPurify (dual-licensed MPL-2.0 OR Apache-2.0 — Nyx AI elects Apache-2.0): (c) Cure53 and contributors. HTML/XSS sanitiser, pulled in transitively via Monaco Editor.

Other bundled components use licences whose conditions are met through the captured full-text notices and component inventory (including MIT, BSD-2-Clause, BSD-3-Clause, ISC, BlueOak-1.0.0, and elected Apache-2.0 terms). BlueOak-1.0.0 specifically requires recipients to receive the licence text or a link; the generated full-text notice supplies it. See docs/third-party-licenses.md.

Build-tool acknowledgements

TypeScript and sharp are used by the build pipeline under Apache-2.0. They are acknowledged here separately from the runtime list because this heading does not assert that those build tools are redistributed in the application.

Native binaries

• @napi-rs/canvas 0.1.80 (MIT wrapper) ships a native Windows PE that statically embeds Skia, ICU, Expat, FreeType, HarfBuzz, Brotli, Highway, JPEG XL, libjpeg-turbo, libpng, libwebp, Wuffs, zlib, libavif/libaom, mimalloc, and Rust crates that include MPL-2.0-covered parser files. Exact upstream pins, licence conditions, binary-attested crate versions, and the upstream tag's missing historical Cargo.lock limitation are recorded in docs/commercial-licence-audit.md. Captured native notices are reproduced in docs/third-party-licenses-full.txt. Exact Source Code Form for cssparser 0.35.0, cssparser-color 0.3.0, and dtoa-short 0.3.5 is provided through the exact public object links in docs/open-source-compliance.md; hashes and resolution evidence are also in that document and the bundled legal/source-offers.json manifest.
• Electron bundles Chromium (BSD-3-Clause + many third-party notices), Node.js (MIT), V8, Skia, and ANGLE under their own licences. The Chromium/Electron notice bundle (LICENSES.chromium.html) generated by electron-builder ships with the packaged application.
• FFmpeg (LGPL-2.1-or-later) is bundled inside Electron as a dynamically-linked, unmodified ffmpeg.dll. Nyx AI does not modify Electron's bundled FFmpeg build. Relevant LGPL notices and licence text are included in LICENSES.chromium.html; this notice is not a grant of rights or legal advice about LGPL compliance. For the current build, Electron is v41.10.5; its exact source tag and dependency pins are at https://github.com/electron/electron/tree/v41.10.5, including the Chromium revision that selects the matching FFmpeg tree. For at least three years from distribution, NYX LIMITED will provide on request the corresponding machine-readable source and the materials required by LGPL-2.1 section 6 for this distributed build, including applicable build scripts or object/relinking materials, for no more than the reasonable cost of physical distribution. The same materials are made available through the exact public object links and hashes in docs/open-source-compliance.md; for a newly staged build those objects may still be publication-pending, and until a link is live the written offer above and the email route below provide them. Request them from customerservice@nyxlimited.com and identify your Nyx AI and Electron versions. NYX LIMITED retains release-gated technical evidence backing this offer — the exact corresponding-source pins, upstream-published digests, and verified hashes for the shipped Electron version — validated against the staged build at release time. The approved upload workflow publishes and reads back those immutable source/relinking objects before it publishes the update manifest; see docs/open-source-compliance.md.
• DirectX Shader Compiler (dxcompiler.dll and dxil.dll) is redistributed unmodified as part of Electron's Windows distribution, which ships these binaries for Chromium's WebGPU (Dawn) shader pipeline. They are built from Microsoft's LLVM/Clang-derived DirectXShaderCompiler project — (c) Microsoft Corporation; portions (c) University of Illinois at Urbana-Champaign (LLVM project) — and are used under the University of Illinois/NCSA Open Source License, a permissive licence with no source-provision obligation. The project and its full licence text are at https://github.com/microsoft/DirectXShaderCompiler.
• @vscode/ripgrep bundles a platform ripgrep binary (MIT/Unlicense) with its own notices.

Fonts, icons, grammars, and speech

• Interface icons — some icons are derived from Feather (MIT, (c) Cole Bemis), https://github.com/feathericons/feather. Nyx AI does not display any third-party service logo; integrations are shown with generic glyphs. Where an integration or provider is named in text (e.g. GitHub, Slack), that name is a trademark of its respective owner, used only to identify the integration.
• Fonts — the interface bundles Inter ((c) The Inter Project Authors), JetBrains Mono ((c) The JetBrains Mono Project Authors), and Fraunces ((c) The Fraunces Project Authors), plus KaTeX's KaTeX_* math fonts — all under the SIL Open Font License 1.1 (full text + copyrights shipped as legal/fonts-OFL.txt; source at src/renderer/styles/fonts/OFL.txt). 1.5.87 — the three interface fonts are now self-hosted / bundled (previously fetched at runtime from Google Fonts), so no font request leaves the machine — the fonts no longer contact Google Fonts servers.
• Tree-sitter runtime and grammars — tree-sitter-assets/ ships six prebuilt grammar WASMs (JavaScript, TypeScript, TSX, Python, Rust, and Go) plus two explicitly inventoried runtime-engine WASMs. The tree-sitter-wasms@0.1.13 wrapper is Unlicense; every runtime/grammar remains under its own upstream MIT notice. Exact filenames, versions, source commits, npm integrity values, and SHA-256 hashes are recorded in docs/licenses-inventory.json; the full notices (including Maxim Sokolov's Rust notice, and the shared TypeScript/TSX repository notice) are reproduced in docs/third-party-licenses-full.txt.
• Text-to-speech (read-aloud) uses the operating system's own installed voices via the Web Speech API. Nyx AI bundles, copies, or redistributes no voice files and no speech engine; the user's ability to use those voices is governed by their operating system and its applicable terms.

2. AI models and inference providers

Nyx AI ships no AI model weights. Models run on the user's own machine (local Ollama) or through a remote endpoint the user configures or selects. A remote endpoint may be a keyless Ollama server or a provider authenticated with the user's own API key (such as Ollama Cloud, OpenAI, Anthropic, or an OpenAI-compatible endpoint). Nyx AI is an orchestrating client and does not redistribute, host, fine-tune, or proxy model weights or outputs as a model provider. It does retain the user's model responses and generated artifacts locally when they are kept in Nyx AI chat history; that local application storage is described in the Privacy Policy.

Each connected model is governed by its own provider's licence and terms, which apply to the user's use of that model through the configured endpoint and, where applicable, the user's key.

Built with Llama

Where a user connects a Meta Llama model (for example Llama 4 / llama4-scout), that model is provided under the Llama Community License Agreement. That licence requires products built on or incorporating Llama models to display "Built with Llama". Whether that requirement reaches a model-neutral client such as Nyx AI, which does not bundle or redistribute any Llama model, can be fact-sensitive; this product displays the notice out of caution:

Built with Llama

"Llama" is a trademark of Meta Platforms, Inc. Nyx AI is not affiliated with, endorsed by, or sponsored by Meta.

Model-specific licence conditions

Model and provider terms vary by exact model and can change independently of Nyx AI. Nyx AI ships no model weights. MiniMax M3 terms reviewed 13 July 2026 permit commercial use subject to licence conditions, including attribution, notice, and revenue-dependent authorisation terms. Nyx AI does not bundle or promote MiniMax models and does not auto-route background or agent work to them. Any model-picker licence note is informational: users must check the current terms for the exact model, provider, account, and intended use.

Trademarks

Model and provider names referenced in Nyx AI, including Llama (Meta), GPT/gpt-oss (OpenAI), Claude (Anthropic), Gemini (Google), Qwen (Alibaba), DeepSeek, Kimi (Moonshot AI), GLM (Z.ai), MiniMax, and Ollama, are trademarks of their respective owners. Their use in Nyx AI is for identification and compatibility only and implies no affiliation, partnership, or endorsement in either direction.
