Dragonflight
Dragon Flight — fly a dragon through neon rings at speed, full HUD, fire-breath, fury meter.
What I asked each model — the Dragonflight prompt
Every model on this page got this exact prompt inside the Agent Operating System: Dragon Flight — fly a dragon through neon rings at speed, full HUD, fire-breath, fury meter.
Single HTML file out. No iteration. No examples in the system prompt. Whatever each model produced on the first run is what's on this page. 25 frontier models have attempted it so far: Claude Fable 5, Fugu Ultra, Fugu Ultra 1.1, Fugu Mini, Fusion, Gemini 3.6 Flash, GLM-5.2, GPT-5.6 Sol, Grok, Inkling, Kimi K3, MiniMax M3, Hermes MoA, Muse Spark 1.2, Opus 4.8, Claude Opus 5, Qwen 3.8, Qwen 3.7, Claude Sonnet 5, DeepSeek V4 Pro, DeepSeek V4 Flash, Kimi K2.7, Kimi K2.7 · Fast, Kimi K2.7 · No-Think, Kimi K2.7 · Quality.
Why this task matters. Dragonflight is a textbook test of game-class capability — the kind of build that exposes whether a model is doing pattern-matching or actual reasoning. A model that ships this in one shot is usually safe to wire into your agent loop for harder tasks of the same shape.
How each model handled Dragonflight
Ranked by my 0–10 score from the source comparison guides on agentos.guide. Click any to play the actual one-shot HTML the model produced.
What I saw: Renders cleanly with a polished neon HUD (speed/score/rings/fury), a large glowing ring, floating decor and a green winged dragon — all brief elements present. Weak spot is the camera framing: the dragon is oddly close and awkwardly angled with wings dominating the frame, giving a less-controlled, generic feel versus the field's best.
What I saw: Ultra v2 — dragon through neon rings, full HUD. Smoke-test PASS (4.2% pixel diff).
What I saw: Full polished HUD (health/fury/alt/speed, score, rings, wyverns) and neon rings plus a visible enemy wyvern are present, but the dragon model renders as a jumbled red-blob mess with scattered floating parts, and the scene reads as cluttered/broken rather than a clean flight; combat and fire-breath appear plausible in source but the visual execution undercuts it.
What I saw: Dragon flight through neon rings with HUD. Smoke-test PASS.
What I saw: RETRY @ 24K tokens — now complete: 27KB three.js + WebGL with rAF + 3 input handlers + closed tags. Fly a dragon through neon rings, score + fire-breath gauge + fury meter HUD. The original truncated attempt has been replaced.
What I saw: Polished HUD with vitals, fury, score/rings/wyverns and clean neon aesthetic, plus a decent 3D dragon and visible enemy/rings in-scene; however the world reads dim and empty with barely-visible rings and no combat action shown, keeping it below the strong bar.
What I saw: Renders a well-modeled segmented dragon with wings, glowing neon rings, cityscape depth and a clean full HUD (score/rings/velocity/combo, fury core meter, message banner, controls) that nails the brief; slightly generic minimalist environment and no visible fire-breath in this frame keep it just under the top-tier winners.
What I saw: Fly a dragon through neon rings with score + fire-breath + fury HUD. 28KB.
What I saw: Strong HUD styling — title, Speed/Rings stats, and a polished fury meter all render crisply — but the screenshot shows a nearly empty scene with no visible dragon and only one distant ring dominating the frame, so the core flight gameplay reads as broken/off-camera at this moment. Great chrome, weak visual payoff.

▶ LIVEHow I scored Dragonflight — methodology
Three axes, 0–10 each, averaged. Runs: drop the .html in a browser; if it opens to a broken page, it scores zero. Hits the brief: did the model ship the thing the prompt asked for, or a different thing it found easier. Looks good: visual polish, motion, interactivity — where most of the gap between gold and silver lives.
