Unclauded(ClaudeDesktop-ModelIDPatch)

A patch allows the Claude client to accept more ModelIDs.

Supported Versions

• 1.6608.0
• 1.6608.2
• 1.7196.0

The patch scripts auto-detect your installed version and fetch the latest patch definitions from this repository. When a new Claude Desktop version is released, only patch-definitions.json needs updating.

Usage

Require: Installed Claude Desktop & Enable Developer Mode

MacOS

curl -fsSL https://raw.githubusercontent.com/CuzTeam/ClaudeDesktop-ModelIDPatch/refs/heads/main/scripts/patch.sh | bash

Windows PowerShell

irm https://raw.githubusercontent.com/CuzTeam/ClaudeDesktop-ModelIDPatch/refs/heads/main/scripts/patch.ps1 | iex

How It Works

1. Disables Electron asar integrity validation (fuse byte flip in claude.exe)
2. Patches the model name validation function to always return true
3. Fetches patch targets from GitHub at runtime for version compatibility

Remote Patch

The scripts automatically fetch patch-definitions.json from this repo at runtime. This means:

• Users always get the latest patch targets without re-downloading the script
• Adding support for new versions only requires updating the JSON file
• If the remote fetch fails (e.g., no internet), embedded fallback definitions are used
• If the version is unknown, a fallback regex attempts to auto-detect the target function

Adding Support for New Versions

1. Extract app.asar from the new version
2. Search .vite/build/index.js for the pattern:

   function XXX(e){const A=e.toLowerCase();return YYY.test(A)||ZZZ.some(t=>A.includes(t))}
   

3. Add the new entry to patch-definitions.json
4. Submit a PR

Reverting
