PetChat Credits

PetChat combines Cloudflare-hosted scene understanding with on-device speech and Apple media frameworks.

Effective October 1, 2026

Pet dialogue

Cloudflare Workers AI hosts Gemma 4 26B A4B IT by Google for the pet’s replies. PetChat’s prompt and validation are Cerebra’s own application logic. Model output is fictional and can be wrong.

Speech and voices

Speech uses Kokoro-82M v1.0 weights and voice assets, licensed Apache 2.0, through KokoroSwift (MIT). Local phoneme and numerical support includes MisakiSwift (Apache 2.0), MLX Swift (MIT) and MLXUtilsLibrary (Apache 2.0).

Dependencies and assets

PetChat also uses ZIPFoundation (MIT) and Swift Numerics (Apache 2.0) through the pinned speech dependency tree; the Cloudflare Worker uses node-app-attest, cbor, and jpeg-js (BSD 3-Clause) under their repository licenses. Apple AVFoundation, SwiftUI, Speech, SoundAnalysis, Core Image and related system frameworks provide camera, listening and media functions. The PetChat app icon and interface artwork are original to Cerebra Enterprises. Source and license records are included with the project.

This website

The pet photos on petchat.si were made with FLUX.2 [dev] by Black Forest Labs on Cloudflare Workers AI. The voice samples are PetChat’s own voices. The example lines in “Try it” were written by us; in the app, replies are made up for each moment. The site uses the Nunito typeface under the SIL Open Font License 1.1.
