Qwen3.6 27B vs Step3.7 Flash | Local AI vs OpenRouter

In this video, I put Qwen3.6 27B Q6 running locally head-to-head against Step3.7 Flash through OpenRouter to see how a local model compares against a fast API model on real coding tasks. Both models were given the same prompts so we could compare speed, coding ability, creativity, interactivity, UI polish, physics, and how well each one handled single-file browser projects using HTML, CSS, and JavaScript. In this test, the models build: • A realistic iPhone-style mobile app UI • Sled Sketch, a Line Rider-style physics game with preset tracks • VoltNode Hosting, a modern web hosting company website This is not meant to be a perfect scientific benchmark. It is more of a real-world coding head-to-head to see how these models actually behave when building the same projects side by side. Let me know which model you think won and what matchup I should test next. #Qwen #Qwen36 #StepAI #OpenRouter #LocalAI #LLM #AICoding #OpenSourceAI #RTX3090 #TokenChaser

Prompts Used

1iOS UI Concept
Create a single HTML file that looks as close as possible to a real modern iPhone-style mobile app interface, without using any official logos, trademarks, or copyrighted branding.

The page should show a realistic phone frame with rounded corners, speaker cutout/dynamic-island-style area, status bar, lock/home indicator area, app content area, and smooth mobile-style interactions.

The app should be a modern lifestyle/productivity app with sections such as Today, Calendar, Messages, Smart Home, Wallet, and Settings. Include a polished home screen, bottom tab navigation, notification cards, widgets, toggles, quick actions, calendar events, message previews, smart home controls, and settings panels.

Make the UI feel premium, clean, and phone-native with glass effects, rounded cards, soft gradients, subtle shadows, smooth transitions, haptic-style button animations, and responsive mobile-first design. It should look like a believable mobile app running inside a realistic phone mockup.

Clearly display the model family name being tested somewhere near the top of the app UI so I can tell which version I’m viewing during the recording.

Keep everything in one HTML file with the CSS and JavaScript included. Name the file ios-app-ui.html.

Once finished, review your code, make sure everything works correctly, and fix anything broken or incomplete before giving the final answer.
2Line Rider Remake
Create a single HTML file for a Line Rider-style physics game called Sled Sketch.

The player should be able to draw track lines with the mouse, press play, and watch a small sled rider slide along the track using gravity and physics.

Include drawing, erasing, play/pause, reset rider, clear track, gravity, collision with drawn lines, momentum, bouncing, falling, crash detection, speed display, distance traveled, and best distance saved locally.

Add preset track templates so I can quickly test the game without drawing a full track myself. Include buttons for preset tracks such as Beginner Hill, Big Ramp, Loop Attempt, Zig Zag Drop, Long Distance Run, and Chaos Track. When I click a preset, it should load that track onto the canvas and let me press play immediately.

The player should still be able to edit the preset tracks by drawing more lines or erasing parts of the track. Add a Place Rider option so I can reposition the sled before starting.

Make it feel smooth, playful, and polished with a winter/arcade style, glowing track lines, snow particles, crash effects, speed trails, and simple instructions.

Clearly display the model family name being tested somewhere near the top of the game UI so I can tell which version I’m playing during the recording.

Keep everything in one HTML file with the CSS and JavaScript included. Name the file sled-sketch.html.

Once finished, review your code, make sure everything works correctly, and fix anything broken or incomplete before giving the final answer.
3Web Hosting Website
Create a single HTML file for a modern web hosting company website called VoltNode Hosting.

The site should include a polished hero section, hosting plan cards, VPS hosting, game server hosting, web hosting, feature highlights, server location/status section, testimonials, FAQ, and a call-to-action area.

Make it look like a real hosting company website with a dark tech style, glowing accents, responsive layout, smooth scrolling, hover effects, pricing toggles, clickable FAQ items, and realistic sample content.

Clearly display the model family name being tested somewhere near the top of the page so I can tell which version I’m viewing during the recording.

Keep everything in one HTML file with the CSS and JavaScript included. Name the file voltnode-hosting.html.

Once finished, review your code, make sure everything works correctly, and fix anything broken or incomplete before giving the final answer.
