Wow, I didn’t expect that. The funny thing is that Bun has never rolled out any commercial service and most likely never will.

I just did an annoying refactor, quite a complicated one, and I tried it with Opus 4.5 and it handled it like a boss. I’m impressed.

Hmm, it still can’t handle transparent backgrounds 😩. Only gpt-image can do that. That makes it pretty unusable for icons and artwork for landing pages.

All I want from Nano Banana Pro is support for transparent backgrounds. Is that available?

Hopefully Gemini 3 won’t tank the whole market if it turns out to be a flop.

Just realized that v0 isn’t using the real Next.js dev server or sandboxes. It’s emulating everything in the browser, which means no Prisma or Convex in v0. 😬

Love this growth strategy for AI startups. You’ve gotta be in SF for this to work. Do a super cool looking demo. Get the initial wave of users hyped. Immediately raise a huge seed round, do it fast, because the retention and churn will tank quick as fuck. After raising the money,

It’s going to be a tough one for Comet. Defensibility in AI apps is brutal.

I’m OG. It actually shows how old my account is. I got access to GPT-3 almost five years ago now.

Turns out we could pretty easily add vibecoding support for ChatGPT Apps. Should we? 👀

Inspired by DeepSeek OCR, I tried converting an agent’s working memory into an image. Took a ~1400 word article that Anthropic tokenized to ~3400 tokens. I embedded the text as an image, asked questions and it worked. Tokens dropped to ~900 (~4x fewer). Haven’t checked info loss

Grok Code Fast 1 got nerfed. It’s not reliable for tool calls anymore. It wasn’t a problem a month ago.

Something’s quite fishy about this. They’re no better than the competition, their Trustpilot reviews are brutal, and no one is talking about them on Reddit. It seems strange that they have these numbers.
