We tested GLM 5.3 Flash and Qwen 3.8 Flash in Pi. Same task for both: use ego lite to build an interactive 3D solar system. Qwen cost 3.6x more and ran 1.7x longer, but the output tells a different story. Comment "prompt" below and we'll drop it.

Qwen 3.8 Flash: 1h 13m, $0.18. This one surprised us. Smooth orbital animation, thoughtful lighting, a few small details we didn't ask for but were glad to see. Clearly spent the extra time refining before calling it done. Results:

GLM 5.3 Flash: 43min, $0.05. Solid and quick. Planets in place, orbits working, nothing broken. It just didn't have the extra layer of detail that made Qwen's build feel finished. Results:

You know what I'm gonna say ego don't you :)

lol bro did u join our discord server 😭 you’d be the first one to get windows version

Joining right now

cost and runtime tell only half the story. if the more expensive run produces a meaningfully better workflow, the useful metric is value per completed task rather than tokens alone.

love it 🥰

Build the most visually stunning and coherent single HTML interactive experience: an accelerated 3D simulation of the solar system. First, use ego lite to find and study one or two exceptional interactive space visualizations for inspiration. Create a cinematic star field with the Sun, eight planets, realistic orbital motion, visible orbit paths, adjustable time speed, pause, reset, camera rotation, zoom, and clickable planet information. Add a polished modern HUD with clear controls and elegant visual design. Use Three.js. Keep everything in one HTML file and avoid unnecessary features. After the core experience works, use ego lite for one brief validation pass and fix obvious issues.

You must let me join our broken system, and I will give you the feedback you need like crazy.Please private message me, my friend.

Interesting benchmark. Curious what made Qwen costlier — is it token usage or model behavior?
