At first glance, Opus and Sonnet 4 do appear to be better than 3.7 at writing and coding. I just updated all of my projects to use Opus 4 and the responses are of a noticeably higher quality.
I have noticed that Gemini, GPT4*, and the others do not do well at writing feature tests so that's one of the first places I start. Sonnet 4 just did a really good job from the random old controller/service code I gave it.
Exciting times- good work Anthropic.
Sadly Claude Opus 4 is on the MAX plan on Cursor :(
But I can already see more relevant content from my claude desktop project either.

@jean_willame Dang it's still not out on Windsurf.

Claude 4’s Opus and Sonnet are really impressive, especially in code generation and reasoning tasks. The audio changelog feature is unique too. I find it slightly faster than GPT-4 on some coding problems but still catching up in broad creativity. Anyone else testing multi-turn conversations?

@parth_ahir What's a multi-turn conversation?

@steveb A multi-turn conversation is when you and an AI go back and forth, with the AI remembering context—just like a real chat between people. (What we usually do with AI)

Ever since Claude 4 was released, I've been excitedly testing it all day. I found that using the same prompt, Claude 4 generates webpages that are more colorful, smoother in interaction, and richer in detail than before.
And web games built with Claude 4 also have impressive detail and smoother interactivity. For example, I used this simple prompt in @Trickle which now powered by Claude 4: "Build a fully functional Tetris game with clean UI, basic controls, score display, and level tracking." — and the result was a highly playable Tetris game, right out of the box.
And for the pricing, Sonnet 4 keeps similar pricing to earlier versions, while Opus 4 uses more tokens but offers significantly deeper detail and more comprehensive outputs at a higher price.
If you're curious how Claude 4 performs in real-world UI/web/game/app building, try vibe coding with Trickle and see the difference for yourself. 😉
what stood out to me most was their focus on marketing AI agents capable of :
working on long . sustained tasks ,
understanding nuanced , real-world contexts ,
and collaborating effectively with humans .
They've also stayed firm on safety and interpretability ,which shows they're serious about making AI a co-worker ,not just a flashy tool .
This feels bigger than just shipping features - it's about redefining the relationship between humans and machines . A new kind of production dynamic is taking shape , and it's setting the stage for a future where developers and AI can truly co-create.
