--- title: Grand Theft Timeline Mods: The Workshop and the AI Mod Kit description: How Grand Theft Timeline mods work: the mod kit that ships with the game, Steam Workshop worlds, what the AI disclosure says, and whether making mods costs anything. url: https://grandthefttimelinegame.wiki/game/mods-workshop/ --- Game info · mods, Workshop and AI # Grand Theft Timeline mods, Steam Workshop and the AI mod kit **Short answer:** Grand Theft Timeline mods are part of the game from day one. A **mod kit ships with the game**, you can **download community worlds from Steam Workshop**, and you make your own by describing them to an **AI of your choice**, with no coding. The kit is free; any cost comes from the AI service you use. Sources: the Steam store page and its AI disclosure Steam , the August announcement, and two developer replies from 10 November Developer . ## What is the Grand Theft Timeline mod kit? The store feature list: “STEAM WORKSHOP! Download community worlds, or make your own with the mod kit that comes with the game, no skill required” Steam . The Early Access answers go further: the game “is built from the ground up on modded systems”, and the developer’s stated reason for Early Access is to “turn GTT into a game created by you, the real players” with “the most advanced and easy to use modkit”. Mods were not always certain for launch. In August the developer wrote that easy mod support, “so players can add their own levels, loot, and NPCs”, was being prioritised because of many requests, but might arrive “at launch or maybe a bit later” Steam . The current store text lists the mod kit with Workshop support as part of the complete Early Access game, so it is planned for 19 November. ### What mods can add (stated) - Worlds and levels - Loot - NPCs ### Planned later (“plans, not promises”) - More mod kit tools - New kinds of features, “not just new worlds” - Higher-fidelity modded content over time ## How does Steam Workshop work for Grand Theft Timeline? Workshop is where community worlds are shared: you “download community worlds” there, and worlds you make can go there Steam . Steam tags the game Moddable. The store also carries two separate trailers, “Authored Worlds Trailer (Non Modded)” and “Modded Trailer”, so the studio draws a line between its own worlds and community ones. The usual Steam Workshop pattern is that you subscribe to an item and it downloads with the game. How subscribed worlds appear in the “Pick Your Timeline” menu, and whether every friend in a [co-op session](https://grandthefttimelinegame.wiki/game/co-op-multiplayer/) must subscribe too, has not been shown yet. The Workshop page for the game will only fill once the game is out. ## Is the AI mod creation free? Mostly. On 10 November a player asked whether AI mod creation would cost something. The developer’s answer: it is “free kind of yes”. You use the mod kit tools “with whatever AI you choose (chatgpt, claude, etc)”, so what you pay “depends on what ai you use, how much you ask from it” Developer . - The mod kit comes with the game: no extra purchase. - You connect or use an AI service you pick. - That service’s own pricing applies: a free tier may be enough for small mods; heavy use may need a paid plan. Asked “so you just vibecode it?”, the developer replied that it “doesn’t involve any coding” Developer . Which AI services are supported beyond the two named, and whether you need an API key, has not been published. _[Image: A blocky player in a yellow suit beside a pink guard with a circle mask in the Squid Game world, 2021]_ _Squid Game, Game 1, 2021: one of the authored (non-modded) worlds. Official screenshot: REAL PLAYERS / Steam. _ ## What does the AI disclosure on Steam say? Steam requires developers to say how they use AI-generated content. This game’s disclosure reads, in short: the studio built an “AI-supported mod-engine” so any player can add what they imagine “without any skill required”, and “parts of modded content use AI-generation, lead by real players” Steam . Read literally, the AI disclosure is about modded content; it does not say the authored worlds were made with AI. Not everyone likes it. One player on the forum said a studio called REAL PLAYERS should not use AI at all. Whether that matters to you is your call; the facts are that the mod tools are built around AI and that mods are optional. ## Mods at launch and later The Early Access plan ties mods to the game’s future Steam . The full version is about 24 months away (around late 2028), and what goes into it “depends on you”: the developer wants to expand the mod kit to support new kinds of features and integrate community requests. The store also says the price could rise “as we move to higher fidelity and quality modkit content” (see [price](https://grandthefttimelinegame.wiki/game/release-date-price-platforms/#price)). After release this page will add how to install a Workshop world, the most-subscribed community worlds and any official modding guide.
