What I asked each model — the Neonblaster prompt

Every model on this page got this exact prompt inside the Agent Operating System: Neon Blaster — juicy arcade space shooter, waves, bosses, power-ups, screen-shake, synth music.

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, Fusion, Gemini 3.6 Flash, GLM-5.2, GPT-5.6 Sol, Grok, Inkling, Kimi K2.7, 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, Kimi K2.7 · Fast, Kimi K2.7 · No-Think, Kimi K2.7 · Quality, DeepSeek V4 Pro, DeepSeek V4 Flash.

Why this task matters. Neonblaster 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
• 8.4/10

What I saw: Screenshot shows a polished, on-brief neon shooter with glowing enemies, a firing player ship, a colorful starfield, and a clean HUD; source backs juicy features (waves, bosses, power-ups, screen-shake, synth music, triple/rapid shot). Strong and shippable but slightly generic ship rendering and simple bullet art keep it just below the field's best.

Fugu Ultra Sakana AI
• 6.5/10

What I saw: Ultra v2 — arcade shooter. Smoke-test MAYBE (0.0% diff) — may need a specific start interaction; flagged for manual verification.

Fugu Ultra 1.1 Sakana AI
• 8.2/10

What I saw: Polished 3D low-poly arcade shooter with visible enemies, active combat state (score 238, kills 1, health 75, 5 enemies), power-up pickups, crystals/asteroids scenery and a clean neon HUD — clearly functional and juicy; slightly generic ground-based feel rather than a true space shooter and boss/screen-shake not evident in the still.

Fusion OpenRouter
🥇 9.0/10 · winner · arcade juice

What I saw: RETRY @ 24K tokens — now complete: 30KB with 2 rAFs + 8 input handlers + closed tags. Waves, bosses, power-ups, screen-shake, synth music (Web Audio), neon particle explosions, score HUD. The original truncated attempt has been replaced.

• 6.3/10

What I saw: Polished HUD, 3D player ship, synth audio and juicy neon aesthetic look good, but the screenshot shows no visible enemies or combat—only ambient asteroids/rings and score/kills at 0, reading closer to a walking sim than a juicy shooter. Strong presentation is undercut by the lack of demonstrable enemy waves/bosses on screen.

GPT-5.6 Sol OpenAI
• 8.3/10

What I saw: Clean render with strong neon HUD, scanline/vignette CRT overlay, glowing ship and polished starfield; source shows waves, bosses with health bars, power-ups, screen-shake, and synth music/SFX. Screenshot is a bit empty (no enemies/action visible) which slightly undersells the juice, keeping it just under the top tier.

Grok xAI
• 8.5/10

What I saw: Juicy 2D arcade space shooter — waves, bosses, power-ups, screen-shake, synth music via Web Audio, neon particles. 24KB.

▶ Play Grok's attempt →
Inkling Thinking Machines
• 7.2/10

What I saw: Strong neon HUD/title and clean starfield render with a polished glow aesthetic, and the source covers waves, bosses, power-ups, screen-shake, and synth SFX. However the screenshot shows a sparse, static-looking scene with a tiny player ship and no enemies/action visible, and the 'synth music' is really just one-shot tones rather than a soundtrack, keeping it below the field's best.

Kimi K2.7 Moonshot AI

What I saw: Neon space shooter — waves, particles, score HUD. Solid arcade build at 25KB.

How I scored Neonblaster — 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.
