Simplex (@usesimplex) builds developer-first web agents that companies use to integrate with legacy portals. They're already in production, dispatching freight shipments, downloading customers’ invoices, and fetching websites’ internal APIs.

Congrats on the launch, @skarpoor12 & @marcon680!

How do transformers do physics? Do they use interpretable human methods or invent “alien physics” that’s hard to decipher?

We find evidence for the former, showing that transformers model the simple harmonic oscillator (SHO) with known numerical methods!🧵@ZimingLiu11 @tegmark

@astralmatrix I might be switching to Cursor fwiw

[Andy Zhu @andyandeggs]

A surprisingly elegant abstraction with merkle trees!

Wild that they’re useful outside of crypto

[Aman Sanger @amanrsanger]

An underrated part of Cursor is our codebase indexing system.

It provides efficient indexing/updating without storing any code on our servers.

[Aman Sanger @amanrsanger]

At Cursor, we’re fascinated by the problem of deeply understanding codebases.

One useful primitive we’ve been focused on is code graph construction and traversal.

Here's how/why we're tackling this... (1/12)

[Andy Zhu @andyandeggs]

Games are relevant everywhere

[Aman Sanger @amanrsanger]

At Cursor, we've built very high-quality retrieval datasets (for training embeddings/rerankers).

To do this, we use GPT-4 grading and the Trueskill ratings system (a better version of Elo)

Here’s how.. (1/10)

[Andy Zhu @andyandeggs]

The requests have been answered

[Aman Sanger @amanrsanger]

Try out GPT-V in Cursor!

It's pretty good for building/modifying components!

[Aman Sanger @amanrsanger]

There are some interesting optimizations to consider when running retrieval at scale (in @cursor_ai's case, hundreds of thousands of codebases)

For example, reranking 500K tokens per query

With blob-storage KV-caching and pipelining, it's possible to make this 20x cheaper (1/8)

What a way to end a thriller of a weekend

[Sam Altman @sama]

the mission continues

[Sualeh Asif @sualehasif996]

would love to chat with more @cursor_ai daily users. if you use it daily and hate something about the experience, reply/dm/email/anything and i would love to talk (for ~10 mintues) sometime over the next few days.

HELP ME PLEASE. A MAN NEEDS HIS NUGGS

[Andy Zhu @andyandeggs]

@nicoritschel @cursor_ai should be able to change the cursorai.action.generateInTerminal shortcut!

[Andy Zhu @andyandeggs]

@nton__ @cursor_ai have you played around with /edit in chat? quite good for making waiting a bit more fun.

[Andy Zhu @andyandeggs]

@QiaochuYuan have you considered san diego? lovely and restful and slow

[Andy Zhu @andyandeggs]

@BenjaminDEKR engineers engineers engineers

[Andy Zhu @andyandeggs]

come work with us :)

[Aman Sanger @amanrsanger]

Coding just got a little more delightful.

We've raised an 8M seed round, led by the OpenAI Startup Fund to build Cursor!

@iamDeeSigner kinda - we're looking for engineers that have design experience - more info at https://t.co/rb04LcxVRU

i love dalle-3

this seal is so damn cute

[Andy Zhu @andyandeggs]

@benank_ @Hasnainzelliam @cursor_ai Yep! We have an "AI fix in chat" feature (hover over errors in your code), as well as command + L to give chat the correct error context
