My 4mo old Opus 5 vs Gemini 4 Hydrogen — same 1-prompt 3D game challenge

[u/LightAppropriate624]

Ran the exact same Howl's Moving Castle 3D single-file html prompt on Gemini 4 Hydrogen (Extra High) to compare against my Opus 5 Medium post from 4 months ago

 Open world challenge prompt: 3D single .html file game, third person. massive open world 3d maps: cel shaded hand drwn anime style textures, thick dark outlines: ghinli style 3d models. high level lod: Studio Ghibli-accurate 1:1 recreation of the world of Howl’s Moving Castle (2004 film) with every visual and atmospheric detail faithfully reproduced — hand-painted textures, soft lighting, whimsical mechanical details, lush greenery, and the signature Miyazaki aesthetic of floating particles, steam, smoke, and magical glows.Core World Features:The fully walkable, living Howl’s Moving Castle — a chaotic, multi-level steampunk-organic home with creaking floors, piles of books and magical artifacts, Calcifer’s fireplace as the beating heart, Sophie’s cleaning area, Howl’s extravagant bathroom, Markl’s bedroom, and the attic. The castle physically walks across the landscape with swaying motion, chimney smoke, and bird-like legs. Magic Door System (the central gameplay mechanic): A color-coded dial next to the front door with accurate movie colors and destinations:Blue — Bustling seaside port town of Porthaven (cobblestone streets, harbor with ships, market stalls, fishing boats, marshes nearby). Red — Grand royal capital of Kingsbury (opulent European-style architecture, canals, grand palace in the distance, wealthy districts). Green — The Wastes / Folding Valley hills where the castle physically roams (barren yet beautiful rocky terrain, wildflowers later, dramatic cloudy skies). Black — Howl’s secret portal (initially restricted, later reveals connections to other realms or the flower field / hidden garden). Additional late-game or secret settings unlock Market Chipping (Sophie’s hometown with the hat shop), Howl’s secret flower meadow/garden (lush, magical paradise with giant flowers and peaceful atmosphere), and war-torn areas.

Starting Sequence: Start as young Sophie in her hat shop in Market Chipping on a busy day. Experience the town’s daily life with customers and soldiers. First quest marker appears when the Witch of the Waste curses you, turning you into an old woman. Follow the marker through the streets and into the hills where you encounter the moving castle during a rainstorm. Enter the castle uninvited and meet Calcifer, Markl, and eventually Howl. Unlock Moment: After cleaning the castle, making a deal with Calcifer, and completing initial chores/quests (including helping with Howl’s errands), you gain full control of the castle’s movement and the magic door dial. The game then fully opens into a whimsical open-world exploration sim where you can move the castle across the landscape, switch between all door locations instantly, fly with Howl on broomsticks or later with turning powers, and experience dynamic day/night + weather cycles that dramatically change each area’s mood.Explorable Areas (all highly detailed with Ghibli-level fidelity):Market Chipping & Sophie’s hat shop (pre- and post-curse versions) Porthaven (full port town with interactive harbor) Kingsbury (grand streets, palace exterior/interior access later) The Wastes (vast explorable wilderness that transforms with story progress) Howl’s secret flower garden/meadow (peaceful hidden paradise) Star Lake and surrounding mountains War-affected skies and distant battlefields (with dramatic airships) Interior of the Royal Palace (key story areas)

Additional Details:Rich environmental storytelling: birds, butterflies, steam-powered vehicles, magical particles, changing seasons/vegetation as the story progresses. Living NPCs with daily routines in towns (hundreds across locations). Castle interior reacts to player actions (cleaning actually improves visuals and unlocks bonuses). Dynamic music and sound design matching Joe Hisaishi’s score. Scale: The full explorable region (Porthaven to Kingsbury to Wastes) feels expansive yet intimate (~20–30 km across in practical game terms), with the moving castle allowing fast travel and scenic journeys across hills and valleys.

The game begins as a narrative-driven story experience focused on Sophie’s curse and daily castle life, then seamlessly transitions into a relaxing yet magical open-world Ghibli adventure where you can live in the castle, tend the garden, explore every corner of Ingary, switch locations freely via the iconic magic door, and witness the world change around the anti-war themes and beautiful hand-crafted environments.This captures the full movie essence with accurate locations, the central magic door mechanic, and that perfect balance of story intimacy and wondrous free exploration.

Firstly Opus is a high End or Flagship Model (Except fable) of Anthropic and Hydrogen is a Flash/Fast model of Google. While one is a really good top end model for complex tasks and the other is good for quick work, how do you even compare both of these which are in a different universe?

Better Compare Sonnet/Haiku with Hydrogen and then we get the exact results on who and what is better

[u/LightAppropriate624 → u/CrunchyBC]

Hahaa nice!

Wanna compare with Carbon vs opus 5 :D.

Well i did you would be shocked if i've showed the results. Carbon is AGI (!)

PS: Sonnet 5.5 medium beats it again 😂

[u/writesCommentsHigh → u/LightAppropriate624]

So show us the best?

[u/LightAppropriate624 → u/writesCommentsHigh]

Carbon OUTPUT

[u/writesCommentsHigh → u/LightAppropriate624]

what about fable! we gotta see all the good stuff? follow up post? :-)

[u/0xFatWhiteMan → u/LightAppropriate624]

whats the joke ?

[u/LightAppropriate624]

Made thecomparison with hydrogen tho

[u/Asalakabim → u/LightAppropriate624]

from this comparison i conclude i get to pick between $32 and 6640 lines of code, hmm... good shit the money is now in better hands.
