We’ve rolled out a major update that brings Open Dev Kit and 001 Game Creator even closer together. From now on, an active Open Dev Kit subscription also grants access to the 001 Game Creator beta, along with the ability to vote on and request new 001 features. This makes ODK the main way to support development while directly shaping the future of both tools.
Open Dev Kit – Subscription & 001 Game Creator Access
An Open Dev Kit subscription now does more than just unlock powerful tooling. Subscribers automatically receive access to the 001 Game Creator beta, along with the ability to vote on feature priorities and submit feature requests. This unifies development feedback under a single, streamlined system and ensures that the people actively using our tools have a direct voice in where they go next.
As part of this transition, we also performed a long-overdue cleanup of our feature request backlog. Over 25 previously completed requests that had never been formally closed were finally resolved and documented, while realistic but unfinished ideas were carefully carried forward so nothing important was lost. The result is a much clearer picture of what has already been delivered, what is actively being worked on, and what lies ahead.
Open Dev Kit New Release
A new Open Dev Kit update is here, and it’s a big one, bringing meaningful improvements to usability, performance, and tooling across the entire editor, followed by some important changes coming to our Patreon Insider tiers. This release also ties directly into the updated Patreon structure, as active Open Dev Kit subscriptions now include access to 001 Game Creator beta builds, giving ODK users an additional way to stay on the cutting edge of both tools.
This update delivers several important quality-of-life and engine-level enhancements. Script development has become more robust thanks to the introduction of the script debugger, better error reporting for variable conflicts, and improved editor responsiveness when working with Lua. All of it backed by significant performance gains and reduced memory leaks across function calls, events, and array access. Debugging while testing is now more transparent too, with expanded callback inspection and the ability to clearly detect whether code is running in-editor or in a built application. This also made the API editor usable even while your project is actively running. On the content side, new functionality such as dynamic sprite image overrides, billboard rendering for holograms, image blitting, and initial support for importing 001 Game Creator sprite resources opens up more flexibility for visuals and asset workflows.
A major portion of this update also focuses on OpenAI integration improvements. Image generation now supports background transparency and auto-sizing, while OpenAI services can be tested directly inside the editor for the first time. We’ve expanded support for service tiers (including priority handling), and introduced an option to use AI to generate new themes directly within the theme editor. These additions mark just the beginning of a broader push toward deeper AI-powered tools inside Open Dev Kit, making AI-driven features more powerful, more flexible, and easier to iterate on during development.
This update also includes a broad set of other fixes and refinements aimed at improving stability, clarity, and everyday workflows. We resolved numerous rare crashes, tightened up scripting edge cases, improved error messages, and addressed several memory leaks particularly around structures, arrays, serialization, and JSON handling. This results in a much smoother and more reliable editor experience.
In addition, we’ve added a handful of improvements for both creators and tool developers, including better editor logging, expanded tooltips, new convenience functions for working with vectors, colors, arrays, and text formatting, and small but meaningful improvements to asset importing, debugging, and OpenAI model handling.
Altogether, this release continues our push toward a more stable, performant, and developer-friendly Open Dev Kit, laying stronger foundations while unlocking new creative and technical possibilities.
