About a year ago, I watched this 3Blue1Brown LLM tutorial (https://www.youtube.com/watch?v=eMlx5fFNoYc&t=367s) on how a model’s self-attention mechanism is used to predict the next token in a sequence, and I was surprised by how little we know about what actually happens when processing the sentence “A fluffy blue creature roamed the verdant forest.”
A year later, the field of mechanistic interpretability has seen significant advancements, and we're now able to "decompose" models into interpretable circuits that help explain how LLMs produce predictions. Using the second iteration of an LLM "debugger" I've been working on, I compare the hypothetical representations used in the tutorial to the actual representations I see when extracting a circuit that describes the processing of this specific sentence. If you're into model interpretability, please take a look! https://peterlai.github.io/gpt-circuits/

Hi, check out Emburse (W16). We have virtual and physical cards that you can set for one-time or recurring.

For some companies such as those in manufacturing, enhanced oversight and better spend control are necessary card program requirements. I agree that business credit would add significant value. Thanks for the suggestion.

For now, we're starting with a debit card product because they're easier to launch. Eventually, as the product gains more traction, it will be easier to launch a credit product with the advantages you're looking for.
Which that said, there's plenty of opportunity as a debit card product. We believe that no financial product right now really prioritizes spend control and bookkeeping accuracy in the way we do within our product.

Founder here - looking for feedback on the product. You can think of Emburse as being like AmEx with Expensify-like features built-in. If you're in the process of transitioning from having all spend on a shared corporate card to having cards for each department or employee, definitely take a look.
