About Formula Minus One
Formula Minus One (FM1) is an arcade anti-gravity racer. You choose a pilot and a futuristic ship and race 29 rivals on circuits through neon cities, frozen landscapes, a volcanic level and space, finding racing lines, using slipstream and turbos, and boosting into opponents: there are no weapons, but while a turbo or boost pad is active you can ram rivals for heavy damage, which the store page calls kinetic combat. There are free races and championships with adjustable difficulty, switchable cameras, and replays you can save and export. The developer, Moisés Cabello, says the game was “vibecoded” by one person with no coding background: the first month of work was done with Codex on GPT-5.5 high “without writing a line of code”, and the code and tooling now come from frontier models from OpenAI and Anthropic, with open-source models filling gaps, while the developer makes the design decisions. The ships, characters and environments start as pencil sketches that become images, then 3D models with Tripo and Blender clean-up; the music is sketched on a MIDI keyboard and finished with Suno. Built with Three.js, WebGPU, TypeScript and Rapier physics. A free open beta plays in the browser on desktop and mobile; the Steam version for Windows, macOS and Linux is listed as coming soon, and the developer says it launches on Steam first, in February.

How it was built
Partially verifiedIn the first post about the game (r/VibeCodeDevs, 28 May 2026, UTC) the developer writes that work started “with Codex on GPT-5.5 high”, Magnific for 2D assets and Tripo3D for 3D models, and that a month later the game was fully playable “without writing a line of code”; the developer also had the model build a custom in-game level editor. In August the developer described the project as a test of whether “one person, with no coding background” could finish such a game, and said they now use Fable for planning and connect Opus and Sol to Blender. The October post lists “Code and tooling: frontier LLMs from OpenAI and Anthropic, with open-source models filling in the gaps and limiting the budget”, and in a reply the developer says the subscriptions are ChatGPT Pro and Claude Max. Which apps run the Anthropic models is not stated, so no Claude tool is recorded.

Three.js with WebGPU, TypeScript and Rapier for physics, with no Godot or Unity; the desktop build is packaged with Electron per the Steam requirements. The developer had the model build an in-game level editor early on, so levels and asset placement are designed by hand rather than through chat, and terrain is a custom system that mixes procedural noise with dunes, ridges and craters and carves space for the track. The October post says every level was thrown away and rebuilt from scratch after feedback, with a written design and style guide (semi-low-poly characters and duotone as the signature look). Characters, ships and environments go from pencil sketch to a GPT image, then to a 3D model in Tripo, cleaned up in Blender, with the model sometimes driving Blender and Tripo itself; the volcanic level is based on real 3D and satellite maps of Teide. Sound effects are stock (Magnific); the music is sketched on a MIDI keyboard and generated with Suno. Steam's AI disclosure says the generated content is prepared in advance and the game does not connect to AI services during play.

“I tried to choose and design everything, and let the LLM to be just a tool.”- Vibecoded a futuristic racer demo like many, but I stuck with it for 6 months now (r/aigamedev)

Verification notes: AI use from three posts by u/ActionLittle4176: r/VibeCodeDevs (28 May 2026, 14:36 UTC), r/vibecoding (22 Aug 2026, 16:53 UTC) and r/aigamedev (12 Oct 2026, 21:53 UTC), plus the developer's replies, read from the Arctic Shift Reddit archive on 7 Nov 2026. Developer and publisher (Moisés Cabello), Coming soon status, platforms, system requirements, languages and the AI disclosure from the Steam store page and API, re-read on 7 Nov 2026; Steam shows no reviews. The posts link the Steam page and the beta; the Steam page's website is fm1.moises.cloud, the address used in the May and August posts. Codex is the only coding tool the developer names; the later posts speak of frontier models from OpenAI and Anthropic and name Fable, Opus and Sol as models, so those stay in the usage text. “Without writing a line of code” refers to the first month; no AI share is stated for the later work, so none is recorded. Steam's AI disclosure covers images, textures, 3D models, music and help with translations, and does not mention code. Team size is from the August post (“one person”); the developer says the ChatGPT Pro and Claude Max plans are shared subscriptions also used for work, not bought for the game. The February launch is the developer's statement; Steam shows only “Coming soon”. The developer mentions Wipeout and F-Zero among the racers that inspired the genre choice; no third-party names or assets are used. The browser beta's start screen was in Spanish when fetched, and the developer says the level editor is in their native language; Steam lists ten interface languages. The October post had a score of 226 on Arctic Shift and the August post 987 (observed; not metrics). The game was not played.
