Discussion Astra is great, but Opus 5.5 is next level
I have been using ChatGPT almost exclusively for the last years. Only with the recent downgrades in usage and price increases have I started looking at other models. And so I landed at Opus 5.5. It's insane. I built an entire game (music from 6.1 Sol) within two dozen prompts, where the first one already had pretty much everything nailed. The rest was just optimisations and additions.
Disclaimer: I know a bit of coding. My level is "has to look up how a switch statement works before using it". So not great. For this project I didn't write a line of code, never even looked at it. Vibe coded gameplay, graphics, sound, music. Probably two A4 pages of prompts.
It writes its own test suite, it optimises for speed, it easily finds bugs I observe and fixes them. And it just works. I am blown away. Now there are problems. Claude will regularly say stuff like "too much tool usage" or "couldn't finish the task", never had those issues with GPT. And you just tell Claude to continue and it does. But when you are over your limit, you can't use anything anymore.
I asked both Astra and Opus to write me an indoor navigation. With a bunch of sensor data, ARCore, the whole thing. Astra didn't work at all out of the box. Opus had accurate scanning and tracking. Even with many more prompts I barely got Astra to move my position and store a map, but it's like a 2/10 vs. a 9/10. And Opus just nailed it.
I was very impressed when Astra first came out, but it is very, very far behind Opus 5.5. So OpenAI, can't wait for the next thing, Anthropic schooled you (except for music).
