Yes, or I would even come back to it at a later time (after it's usually caused me a few headaches)

I have a decent amount of success asking it "how does feature X work?". The process of me understanding it usually means I can make improvements here or there

What do LLMs see?

I wrote a lil' tool that extracts the attention matrices out of open models and creates this typing visual, with each token's opacity changing according to its average attention score as the prompt progresses. Dimmer words are considered less important to the model.

Having a little fun with some fragment shaders. Progressively quantising the word "quantisation" because I have no sense of subtlety.

In graph theory, there are algorithms that find the shortest path between two nodes. I made one with pure CSS (including the graph drawing).

Drag the nodes, and the shortest path will update in real-time!

That's mad. I genuinely have a signed autograph from him. I cried on my first day of school when people called said "oh you're like Michael Owen" and I thought they were teasing me

I'm at that frothy point with a side project where there's about a million different directions I could take with it. It's equal amounts of exciting and terrifying

Can anyone recommend any materials that give a less experienced engineer's take on AI, and how it's impacted them? I've got privelage in that I see it largely as a benefit for me, but want to understand how someone who's less likely to know what "good" looks like can steer this monster

For what it's worth, and I won't be taking feedback on this:
- Enter is new line. Cmd+Enter send the message. IDGAF if I'm in the middle of some bullet points
- Scrollwheel pans the canvas. Cmd + scrollwheel zooms in/out
- Cmd + Shift + M, but I might buy a streamdeck just for this

In the last week work has given me Claude max and a n8n subscription. I can remember the last time I had the opportunity to do this much damage
