So Scratch will add AI blocks, indeed. but they are in testing. I even made a scratch based on it, but this isn't that one. If you want to get it though, you will have to follow these steps. First, click the green flag (DUH), then click or press space on the project and a list will show up. Second, select it and click on export. Third, after, go to your OS text editor or any other and open the file with it. Fourth, after that, save it as a .SB3 file. Now you gotta go to "https://lab.scratch.mit.edu/ai-blocks/", which will look like scratch, but it is really Scratch Lab, go to file, click "Load from your computer" and that's it.
The project is basically what i like to call ScratchGPT, a totally advanced AI being developed by the Scratch team with totally official collaborations with OpenAI! It totally won't stop working after a modest amout of use! And it totally wont stop working until the very next epoch! Totally not going to be fully released in late 2026! But seriously, why does the Scratch Team always leave projects in experimental stage and they actually get into scratch when a miracle happens?
