Fangyuan025/Chaty v2.3.0

on GitHub

Pictures, drawn on your own GPU

Load a text-to-image model — Z-Image Turbo, Qwen-Image 2.1, FLUX.1,
Chroma, Stable Diffusion — and the whole app becomes an image studio:
sessions that read like conversations, a live preview while it draws,
each model's recommended settings filled in, and editing that starts
the next round from any picture. A GGUF is only the denoiser; Chaty
finds its VAE and text encoder, or downloads the missing ones in one
click. It runs on stable-diffusion.cpp in a helper of its own — Metal
on a Mac, Vulkan on Windows and Linux. On an M4 Pro, Z-Image Turbo
draws 1024 × 1024 in under three minutes.

Each model in its own dialect

K2 Horizon loads on both engines, MoVA-36B included, with its own
reasoning tags and effort ladder. GLM-4.5/4.6/4.7 and MiniCPM5 tool
calls are read and written in their own formats — GLM's had been no
call at all. A GGUF whose own chat template says more than
llama.cpp's built-in guess is rendered from the template, as
transformers would (MiniCPM5 answered in fragments without it), and
a refused model says why in llama.cpp's own words.

Edits that land

An edit is checked against the file while the model is still writing
it, and stopped the moment it cannot land. A retyped line with the
wrong spaces, escapes or line numbers lands where exactly one place
fits; calls written in every shape small models actually use are
read; and a long diff now opens in full.

A quieter, more finished look

The window is redesigned: one frame, a floating composer, the app's
own menus throughout, and the accent kept for what matters. Settings
are regrouped, and a line above the composer shows what the next
message will use. All of Settings → Sampling but temperature now
applies to Code as well.

Also: MLX models stop cleanly (the repetition penalty had been
counting the prompt's own markup), and a round of fixes to races,
recovery paths and a window that froze on slow commands.

Install

macOS first launch — "Apple could not verify…" / "damaged"

Chaty is ad-hoc signed but not notarized (no paid Apple Developer
account), so Gatekeeper flags it on first launch. The app is safe —
everything runs locally. Clear the download quarantine once, in Terminal:

xattr -dr com.apple.quarantine /Applications/Chaty.app

Then open Chaty normally. (Alternatively: try to open it once, then go to
System Settings → Privacy & Security → Open Anyway.)
