What I asked each model — the Outrun prompt

Every model on this page got this exact prompt inside the Agent Operating System: Outrun — synthwave horizon driving game with pseudo-3D road.

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. 24 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 K2.7, Kimi K3, MiniMax M3, Hermes MoA, Opus 4.8, Claude Opus 5, Qwen 3.8, Qwen 3.7, Claude Sonnet 5, Kimi K2.7 · Fast, Kimi K2.7 · No-Think, Kimi K2.7 · Quality, DeepSeek V4 Pro, DeepSeek V4 Flash.

Why this task matters. Outrun 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.

Claude Fable 5 Anthropic
🥇 8.7/10 · synthwave outrun perfection

What I saw: Gorgeous synthwave palette with banded retro sun, parallax mountains, glowing palms and neon-edged pseudo-3D road with a curving horizon and traffic — genuinely polished and on-brief; only nit is the player car sits a touch high with a slightly floaty tail-light bar, but this clearly matches or beats the field best.

Fugu Ultra Sakana AI
• 7.0/10

What I saw: Ultra v2 (gap-fill, 19-min direct call) — 36KB pseudo-3D OutRun racer: curving/cresting road, synthwave sunset, parallax mountains, 2 rAF loops. Smoke-test MAYBE (0.1% diff) — road advances on held-accelerate which the brief keypress didn't sustain; flagged for manual verification.

Fugu Ultra 1.1 Sakana AI
• 8.6/10 · neon combat runner

What I saw: Gorgeous synthwave city with pseudo-3D road, glowing hero craft on a contact disc, and a visible enemy vehicle ahead with combat HUD (KILLS, THREAT HIGH, crosshair) — clearly a combat runner not an empty walking sim. Polished vignette, meters, and banner elevate it above the field's best; only minor knock is the driving game reads more as a hover-shooter than pure Outrun cruiser.

Fugu Mini Sakana AI
• 8.5/10

What I saw: Pseudo-3D OutRun racer with synthwave horizon. Smoke-test PASS (26% pixel diff after arrow keys).

Fusion OpenRouter
• 8.0/10

What I saw: Pseudo-3D OutRun racer with curving + cresting road, synthwave horizon, parallax scenery. Arrow-key steering + accel.

• 8.4/10 · synthwave combat runner

What I saw: Gorgeous synthwave scene with pseudo-3D grid road, glowing sun, neon palms, polished HUD and an on-road enemy plus reticle showing real combat mechanics; loses a touch because the road perspective looks partly flat/wide rather than a tight curving pseudo-3D outrun feel.

▶ Play Gemini 3.6 Flash's attempt →
GLM-5.2 Zhipu / Z.ai
• 8.5/10 · winner · most complete

What I saw: GLM shipped the full arcade package — an 'OUTRUN 2086' title, gear, RPM and velocity dials, mountains, the car cruising at 90+. Opus's road curves hard past rumble strips and palms into a scanline sun. Kimi's 'NEON OUTRUN' is clean and on-brief. GLM edges it on sheer completeness.

▶ Play GLM-5.2's attempt →
GPT-5.6 Sol OpenAI
🥇 8.7/10 · synthwave outrun perfection

What I saw: Gorgeous, textbook synthwave scene—striped sun, layered mountains, city silhouette, palms, glowing pink-edged road with proper pseudo-3D curve and a neon car—all polished with excellent HUD and title treatment. Only minor nit is the somewhat abstract car sprite, but overall this matches the field's best.

Grok xAI
• 8.0/10

What I saw: Pseudo-3D OutRun racer — curving road, synthwave sunset, parallax scenery. Arrow-key steering. 24KB.

▶ Play Grok's attempt →
Inkling Thinking Machines
• 6.8/10

What I saw: Renders cleanly with a striking neon title, glowing cyan road with dashed center line, and colorful side buildings, but the flat-shaded matte cubes read more like a generic 3D scene than a synthwave city, and there's no sun/horizon gradient or visible car — polished UI but modest atmosphere.

How I scored Outrun — 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.

My scores trace back to the source comparison guides on agentos.guide. See the full methodology page for data provenance, including which source guide each cell's score came from.
