Release Modex Desktop 0.1.1 — public preview · modexai-io/modex-releases

The second public preview. Windows (x64) only.

This build is unsigned, so Windows will show a SmartScreen "unknown publisher" prompt. Verify the installer instead of trusting the prompt:

Get-FileHash Modex-Desktop-0.1.1-x64.exe -Algorithm SHA256

If your antivirus quarantines the download, restore it only after the hash matches. We will never ask you to disable Windows Defender.

Before you upgrade

Modex can now install two optional toolchains — a TeX distribution for LaTeX, and a Python environment for analysis. Neither is downloaded unless you ask for it, and each states its size first.
Load / Unload in Settings → Libraries is now Show / Hide. A library you had loaded is simply shown; nothing is uninstalled.

LaTeX, with the PDF beside the source. A .tex file opens with highlighting and its own Compile button, and compiles on save. Modex can install a pinned TinyTeX (~760 MB) for you, or use a TeX installation you already have.
A real PDF reader — outline, zoom to the pointer, grab-to-pan, find.
The agent runs Python. It can run a script against your simulation results and place a figure it computed into a Modex document. Modex can provision a managed environment (~400 MB) after an approval screen, or use an interpreter it finds on your machine.
Attach an image or a PDF to the agent — paperclip, paste, or drag from the workspace.
A chat transcript that reads like one. Text, tool calls and figures in the order the model produced them, rendered markdown, clickable file mentions, and a docked session column instead of an overlay.
Workspace files open as what they are — images, media, markdown, CSV — and the explorer can create any file type.
New Settings pages: Simulation, OMC, Python and LaTeX.

Settings → Libraries is one list of every library Modex can see, each with one row and one eye. Hiding sticks across a reopen.
Simulation runs no longer accumulate without asking — results have a retention setting, and a run a figure depends on stays protected.
Every field in the run dialog now reaches the solver, or says it cannot.
GPT 5.4 and GPT 5.4 Mini are offered again. They are never chosen automatically, so the default is unchanged.
The update notice can be dismissed.

The assistant can read the files in your workspace again on Windows. In 0.1.0 it refused ordinary files sitting in your workspace root. Nothing was ever at risk — the check was refusing too much, not too little.
The first simulation of a session no longer fails after 15–20 seconds. A cold compiler is now given its full start-up budget, and is warmed at launch rather than on your first Run.
Quitting while Modex is still starting no longer leaves a process behind, which could stop the next launch.
Upgrading no longer removes Modex's registrations from your other AI tools.
A failed agent run tells you what to do — the action to take comes first, the provider's own output follows.
The transcript no longer goes blank while the agent is working. A Thinking cue now covers the stretches where the model works before it writes.
A turn's copy button appears when the turn is over, not while it is still running.
Your choice about anonymous usage data is now honoured by every part of the app. The switch is in Help → About Modex, alongside the update preference.

Upgrading from 0.1.0 clears the registrations in your other AI tools once. An upgrade runs the installed build's uninstaller, so no new installer can change 0.1.0's behaviour. Modex restores the entries the next time it starts, and upgrades from this release onward keep them.
The two Install buttons do not go through an HTTP proxy. On a machine that reaches the internet only through a corporate proxy, installing TeX or Python from Settings will fail. Point Modex at an interpreter or a TeX installation you already have (Settings → Python / LaTeX). The OpenModelica install is unaffected.
