Descript has some nice video/screen recording tools to help beginners make this kind of thing look moderately professional. I've used it for various walkthroughs in my previous place of employment.

olliepro··on Karpathy on DeepSeek-OCR paper: Are pixels better inputs to LLMs than text?
The causal masking means future tokens don’t affect previous tokens embeddings as they evolve throughout the model, but all tokens a processed in parallel… so, yes and no. See this previous HN post (https://news.ycombinator.com/item?id=45644328) about how bidirectional encoders are similar to diffusion’s non-linear way of generating text. Vision transformers use bidirectional encoding b/c of the non-causal nature of image pixels.

> any automation that requires a human staff member to intervene to complete every run is not automation

Not strictly true. Barcode readers are used by humans and are definitely automation. The ironic part though is that the automation going on here is literally object classification, which humans are good at.

The play may be to collect data and make their system better.
