Chaty 2.3.9 డౌన్‌లోడ్

## Engines that update without a Chaty release

Settings → Runtimes lists llama.cpp, stable-diffusion.cpp, audio.cpp and MLX
with the build each is on, and a newer one to switch to at a click — or by
itself, once you turn that on. Every day each engine's newest upstream is
built into this release's own wrappers and published only if it starts; the
list is signed, and a newer engine is checked and started once on your
machine before it is used. One that will not start is set aside and the
bundled one takes over by itself.

## llama.cpp in a process of its own

GGUF models now run in `chaty-llama`, a helper beside the app, as the image,
music and MLX engines already did. That is what lets it be replaced, and a
crash inside llama.cpp ends that process instead of the window. Loading shows
llama.cpp's own progress.

## MLX on upstream

MLX runs on upstream mlx-swift-lm and mlx-swift 0.33 instead of our fork:
upstream's own Qwen3.5 MTP support made it unnecessary. Speculative decoding
stays as fast — Qwen3.5-4B MTPLX at 69 tokens a second against 40 without it
on an M4 Pro.

## Linux

Open models folder works on Fedora：the AppImage no longer carries its own
`xdg-open`, and the programs Chaty starts get your system's environment
instead of the image's library paths (#28). Folders and files are picked with
your desktop's own chooser through the XDG Desktop Portal — Nautilus's on
GNOME, Dolphin's on KDE — with the GTK dialog kept for a desktop with no
portal (#29). Thanks to @davidecelentano for both.

<!-- Highlights go above this line, hand-written per release —
the release page is where people who found Chaty through a
model's name land, and a bare install table tells them
nothing about why this version exists. -->

## Install

| Platform | File |
|---|---|
| **Windows x64** | `Chaty_*_x64-setup.exe` — per-user installer, no admin |
| **macOS (Apple Silicon)** | `Chaty_*_aarch64.dmg` |
| **Linux x64 (beta)** | `Chaty_*_amd64.AppImage` — `chmod +x` and run |

### 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:

```sh
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**.)
