If you, like me, just woke up, let me catch you up on the Claude Code Leak (I know nothing, all conjecture):

> Someone inside Anthropic, got switched to Adaptive reasoning mode
> Their Claude Code switched to Sonnet
> Committed the .map file of Claude Code
> Effectively leaking the ENTIRE CC Source Code
> @realsigridjin was tired after running 2 south korean hackathons in SF, saw the leak
> Rules in Korea are different, he cloned the repo, went to sleep
> Wakes up to 25K stars, and his GF begging him to take it down (she's a copyright lawyer)
> Their team decided - how about we have agents rewrite this in Python!? Surely... this is more legal
> Rewrite in Py
> Board a plane to SK๐Ÿ‡ฐ๐Ÿ‡ท
> One of the guys decides python is slow, is now rewriting ALL OF CLAUDE CODE into Rust.
> Anthropic cannot take down, cannot sue
> Is this "fair use?"
> TL;DR - we're about to have open source Claude Code in RustImage We're going to cover this and a BUNCH more on the weekly @thursdai_pod spaces, join us, don't miss out.

PSA: If you've been running out of Claude session quotas on Max tier, you're not alone. Read this.

Some insane Redditor reverse engineered the Claude binaries with MITM to find 2 bugs that could have caused cache-invalidation. Tokens that aren't cached are 10x-20x more expensive and are killing your quota.

If you're using your API keys with Claude this is even worse. This is also likely why this isn't uniform, while over 500 folks replied to me and said "me too", many (including me) didn't see this issue.

There are 2 issues that are compounded here (per Redditor, I haven't independently confirmed this) :

1s bug he found is a string replacement bug in bun that invalidates cache. Apparently this has to do with the custom @bunjavascript binary that ships with standalone Claude CLI.

The workaround there is to use Claude with `npx @anthropic-ai/claude-code`

2nd bug is worse, he claims that --resume always breaks cache. And there doesn't seem to be a workaround there, except pinning to a very old version (that will miss on tons of features)

This bug is also documented on Github and confirmed by other folks.

I won't entertain the conspiracy theories there that Anthropic "chooses" to ignore these bugs because it gets them more $$$, they are actively benefiting from everyone hitting as much cached tokens as possible, so this is absolutely a great find and it does align with my thoughts earlier.

The very sudden spike in reporting for this, the non-uniform nature (some folks are completely fine, some folks are hitting quotas after saying "hey") definitely points to a bug.

We had a "Cursor tips & tricks" meeting today with my colleagues at @weights_biases and I figured I'd share what we 'discovered' & shared between us in a ๐Ÿงต

If you haven't chatted with your team about how YOU all use Cursor, you def should, but meanwhile here are our insights ๐Ÿ‘‡ Image First we chatted about what features each of us uses and how to edit, the summary is, some folks have tried but are not super comfortable with Composer, CMD+K is useful but often lacks context, and chat sidebar is really great all around.

Takeaways:
Use Command+K to edit inline functions
User Composer when there's a need to edit multiple files
Use Chat with (cmd+shift+L) for everything else

Got my new mac from @weights_biases and it's been a while since I installed one, so will do a X setup thread cause why not?

As always, I never transfer anything, start from scratch every time, this way I get to re-decide what I use!

Thread mostly for me but follow along if u likeImage I'm already a bit into this, but just barely.

First up as always, @1Password, undeniably the most important app to get on your mac first, so than everything else will become easier ๐Ÿซก

@1Password also holds my SSH certificates for a while now, and has an SSH agent, so I no longer have to send my keys over from the older mac.

My Watchtower security score in @1Password is 358 (Weak) ๐Ÿคช ๐Ÿšง ๐Ÿšœ (but keep in mind I've been using 1P for well over a decade and a BUNCH of these are old accounts I no longer use, my important accounts are all unique long passwords and 2 step protected with no sms, and slowly moving to passkeys, which 1P supports!)

#CodeInterpreter - "It's a very fast, coding intern, that's both really smart and really stupid, but the biggest advantage is, it never gets frustrated and never gives up" - @simonw

Here's my evergreen #CodeInterpreterCan thread, w examples, tips, use-cases, and ideas๐Ÿ‘‡

1/ Open AI released Code Interpreter to every paying customer on #ThursdAI Jul 6. It's a watershed moment.

However not until @swyx pinged me and @simonw to discuss it on spaces, did I dive in.

And we're all in agreement, this is groundbreaking!

Whoah ok, @OpenAI has just answered tons of developer requests, let's dig into this.

You know how many folks struggled to get a JSON output consistently? For the use of agents and other stuff?

Well, OpenAI took it 1 step further and gave us function calls! How do they work๐Ÿ‘‡ Image First of all, many developers have struggled with consistent JSON output to their models (yes including me)

This led to hacks like trAI/except and other methods, I saw folks switching to yaml and xml among other solutions

So having native JSON response is just awesome ๐Ÿ’ฏ

Watching @karpathy presentation from today and taking twitter notes, come along for the ride:

If you're like only the practical tips, skip to #32

@karpathy starts with stages:
1 - Pre-training - months x thousands of GPUs
2, 3, 4 - Finetuning stages that take hours or days

1/ Image Before pre-training happens, there are 2 preparation steps.

Data collection - Get tons of data from different sources (here Andrej LLaMa mixture)

Tokenization - a lossless translations between pieces of words and integers.

I just finished watching @ilyasut with @nvidia CEO Jensen, and I was really expecting the discussion about GPT-4 and multi-modality ๐Ÿคฏ

Posting a few highlights, of what I think is going to be a huge, HUGE change in everyone's life soon:
(transcribed w/ Targum of course)
1/ .@ilyasut explains everything in simple terms:
Multimodality is important for two reasons: 1) It's useful, as vision enhances the practicality and value of neural networks. 2) It allows us to learn more about the world through images, in addition to text.

Ok this is my AI new coding paradigms thread, I'll try to keep this updated with things that were not possible before.

Not only tools (god knows there's tons of those) but actual coding paradigms that show a glimpse of the future.

I just had a great experience with @Tesla Littleton.

Our Model Y stopped heating the car and showed a notification to take it into service.

This + two small kids in a 25F weather, no bueno. I scheduled service via the app and the closest appointment was 5 days away.

But I texted them through the App and asked to make sure they have a loaner (they usually give Uber credits) as I need to prepare for a kid weekend, and see if they can squeeze me in. Louis reached out the next day and said to come in immediately and that a loaner is waiting
