@ryoppippi thanks to these gpt resets. I've ran out of tokens and desire more.

[Yunfei He @hyfdev]

Just bought one year Kimi Code subscription. Let me try kimi K3 on the Rolldown project!

@ryoppippi deepseek-v4-pro performs in a quick way

[Yunfei He @hyfdev]

correction: kimi3 >> opus4.8

[Yunfei He @hyfdev]

I've been trying different models these days and here is how I feel

fable >= gpt sol > opus4.8 >= kimi3 > grok4.5

[Yunfei He @hyfdev]

I think grok4.5 and kimi3 are pretty good. I guess the only issue is that they haven't gather enough feedback loop data from real world. Sometimes they just don't get it compared to claude code and codex.

[Yunfei He @hyfdev]

Sometimes I feel like writing a JS parser. But every time I look at Oxc and the near-perfect balance it achieves between performance and feature completeness, my interest fades a little—even though I'd only be doing it for fun.

Maybe I should just do it anyway. I've been meaning to finish reading this for a while:

@forehalo 🫣kimi is the only AI subcription I paid myself

🖋️ Kami is an AI-native tool for typesetting professional documents.

Been wanting this for a while: architecture diagrams that live with your repo. Redraw them and they keep their original intent, and roadmap plans never look like shipped facts.

Volar now has first-class support in tsdown and rolldown-plugin-dts.

It can generate `.d.ts` files for all file types supported by Volar, including Vue and Astro.

@antfu7 @sanxiaozhizi ESM isn't the future. It's the present.

@thsottiaux no 5hr limit forever please

[Yunfei He @hyfdev]

@HiTw93 I use Mole every hour, every day, while working on Rolldown.

[Yunfei He @hyfdev]

@robpalmer2 @NicoloRibaudo Thank you for the info. I could take a look if convenient.

[Yunfei He @hyfdev]

😑 Been dealing with source maps lately. Solving source map issues is no fun at all. But figuring out how to make the process less painful is surprisingly fun.

[Yunfei He @hyfdev]

@yagiznizipli @liangmiQwQ Vite-like speed 👍
