I tested DeepSeek V4 Flash, Kimi K3, and Muse Spark 1.3 on the same Flappy Bird prompt.
Meta Muse Spark 1.3 was my favorite. It built the most complete game with a polished UI, animated bird, layered parallax, pipes, scoring, persistent best score, and a proper game-over
[90% don't know] For those who want to save 30,000 yen per month on AI I completely replaced my Opus 5 with a 1/20th cheap model (Deepseek V4 Flash)
The only weakness = not being able to see the image was solved by just adding 2 packages. People who pay 30,000 yen a month will lose money if they don't know this😳 ・$200 a month has been drastically reduced to 1/20th ・Only 2 commands are used
Hy4 preview just dropped, so I tested it on WorkBuddy against three other models
DeepSeek V4 Flash, GPT-5.6-Luna, and GLM-5.3... the top 4 models on this week’s OpenRouter coding leaderboard. The best part? They’re all available in WorkBuddy, so you don’t need to download
Actually a very neat design, surprisingly hard to improve with vibecoding from scratch.
Good demonstration that you still need taste. I've quickly made a CMYK version with V4-vision:
