AI Summary

Fable is described as a significant improvement over earlier models, especially in long-term planning, maintaining context, and analyzing code. It can continue coding tasks for longer, better identify nuanced bugs and overlooked issues, and is reportedly faster despite its deeper analysis.

Key Points

  • Fable's long-term planning capabilities are described as far superior to earlier models.
  • For coding tasks, Fable continues working for longer.
  • Fable is much better at stitching information together within its context.
  • Compared with earlier models such as Opus, Fable better detects nuanced bugs and overlooked issues in code.
  • Fable provides deeper analysis while being described as unexpectedly faster.

00:00 I guess when you see these benchmarks, and Chris, I'm sure you've played around with it as well. Does it? I mean, does the how's the vibe check? Like, do you feel like the capabilities here are step function more? Any like interesting observation so far there? You know I've, I've spent quite a long time, uh, work at playing with Fable at the moment.

00:17 And it is genuinely a great model is genuinely a step up The first thing is, I would say, is its long term planning capabilities are far superior. So you can run— So if you're doing coding tasks for etc., it is just going to go for longer. The other one, the ability for it to stitch things up within the context again is much, much better. I would have said in the earlier models things like Opus, for example, it wouldn't get so much of the nuances.

00:43 So things like discovering what bug you have in your code, what particular issues you've got going on things that you've never really thought about. In that sense, it's got such a deeper analysis Um, weirdly enough, it's faster and I can't work that out.
