KimiTalk Open-Source Notice

Version: 1.2
Date: 2026-05-26

KimiTalk incorporates open-source software and can prepare local machine learning model weights at the user's request. Current release model downloads are served through KIMIKON-controlled Cloudflare/R2 endpoints (models.kimikon.cc, dmg.kimikon.cc, updates.kimikon.cc), not directly from HuggingFace. HuggingFace remains relevant as an upstream, source, and license reference. Per-component license texts are bundled in Resources/Licenses/ and shown in Settings under Lizenzen & Modellhinweise.

Optional Local Speech Helper / Runtime Model Notices

KimiTalk can optionally use separately installed local speech engines and runtime-prepared model weights. The main app keeps visible notices for:

• OmniVoice / Boson Higgs Audio 2
• Meta Llama 3
• Kokoro-82M
• Qwen3-TTS
• Google Gemma 4
• Qwen local language models
• mlx-community model conversions
• AudioSeal (Local Speech Helper watermark runtime)
• C2PA / c2pa-python (Local Speech Helper provenance runtime)

C2PA is not linked into or vendored by the main KimiTalk.app. Helper-backed AI-audio provenance is created by the separately installed LocalSpeechHelper.app, which bundles c2pa-python/c2pa-rs and carries the full helper NOTICE plus license texts.

Full License Texts

The full Apache License 2.0 text is bundled as Apache-2.0-FULL.txt. Other licenses are bundled in their per-component files. No endorsement by upstream projects is implied unless explicitly stated by those upstream projects.
