Impressed with Claude 4 Opus so far, tested it by prompting it to "make a browser based game that teaches 5 year olds how to read"

Was having fun with my daughter having gpt 4o illustrate a book idea she had and then it came up with this jewel of a photo where the baby seat is external to the car. Gave me a good laugh.

Crushing it with gemini-2.5-pro-exp-03-25 in @cursor_ai! It's showcasing impressive precision and efficiency. Just instruct it to draft its own task list in a file, and watch it effortlessly track progress and stay on track.

Making progress on my game for @levelsio #vibejam - added elimination style rounds and am now spawning AI enemy ships to compete with so players aren't just flying around by themselves. So far have gotten the whole way vibing with Claude Code, have not had to go in IDE.

Just spotted @grok's new "DeeperSearch" feature! Time to dive in and explore how deep it really goes.

Turns out @grok is really good at product research, needed some new house slippers cause mine are falling apart and it generated this handy breakdown for me

Okay, another random developer tool @lovable_dev helped me one-shot: A tool that will look at the hex signature of a file rather than it's extension to determine what the correct extension for the file should be. I love being able to create quick tools for hyper specific cases.

Perhaps now @levelsio will incorporate some polished 3D models into his game!. Code is OSS if anyone wants to contribute or hack on it

Who has time to search and download 3d models when vibe coding games? Thats why I made an MCP server that will go and download the perfect free 3D models for you from SketchFab! Just add "npx -y sketchfab-mcp --api-key [your-sketchfab-api-key]" as a @cursor_ai MCP server.
