60 hours in and I have so far avoided using Fable 5. I feel that trend will likely continue. It's a very smart but still expensive model.

It's great at what it does but someone right defined it as a "Very senior software engineer".

Someday, I will likely use it when I have a really weird bug that my human brain can't comprehend. Until then, I will continue to use claude as a large scale code authoring machine.

@theo my advice. Dont do that!

@CodeWithAmann Why are the Qwen models not listed here !!?

I joined Sierra 6 weeks ago and very quickly thought “this feels different.”

To put things into perspective: in my last job, we had incredible AI tooling and effectively infinite tokens. But despite all of that, it often still felt surprisingly hard to translate capability into momentum.

Tokens were burned, code was generated, but progress still felt slower than expected.

I think I’m finally starting to understand why.

Now that engineering effort is no longer the primary bottleneck to producing output, many traditional software operating models start to feel much heavier:

- sprint rituals
- productivity proxy metrics (tickets closed, LOC, token usage)
- roadmap misalignment
- cross-functional dependency coordination
- layers of design + architecture reviews
- approval chains and stakeholder buy-in
- org boundary negotiations

In a world where it’s cheaper than ever to build and experiment, organizational latency becomes the real bottleneck.

What feels different at Sierra:

1. Quick feedback loops: We’re surrounded by opinionated people who aren’t afraid to say what they think. It’s often faster to iterate than debate. That forces sharper thinking and better design choices.

2. Agency: People are trusted to run with ideas. The distance between “this could exist” and “this is shipped” feels dramatically smaller.

3. Directional alignment: There seems to be a strong shared conviction around direction, which creates room for autonomy while still moving cohesively.

It’s still early for me here, but this is probably the clearest articulation I’ve found so far that “AI-enabled” and “AI-native” are very different things.

@MKBHD strongly believe there needs to be an "iPad OS Pro" / "MacOS lite" that powers the iPad Pros soon. Pro iPads are more powerful than the surface 2-in-1s and still much less capable (held back purely by software)

@DurvidImel Pretty cool knowing very emojis come from, especially being an anime enthusiast. Also what the hell was that other emoji (the blue one) that showed up a lot on the video!?

Just saw @DurvidImel from @MKBHD video 📸 on sparkles with AI and had a great #TIL moment.

Being an #anime enthusiast, knowing emojis originate from there was a great joy. Do check it out 6

@arcinternet Tried @arcinternet on windows and its split browsing and tab management at its simplest. However had some bugs to report. Whats the best way to reach out?

[Aritra Sen @SenTalksSane]

Nevermind @arcinternet whats the easiest way to file a bug that reach you :)
