Karpathy's 3.5-hour LLM deep dive, compressed to 60 seconds. Lossy, like the model.

Biggest builder lesson: weights are vague memory, context is working memory. If it has to be right, put it in the prompt.

What surprised you most?

@thesupermannx harness that outputs editable STEP beats a pretty render every time. if you can't reopen it in real CAD, it's a demo not a deliverable.

@beamnxw 16-step playbooks are great until step 7 invents a new brand color. reusable components + a freeze on the style bible is what actually makes the studio shippable.

[Anshul Karasi @anshulkarasi]

@rezoundous that's the bar now. if they don't clock it mid-watch, continuity held. if they ask "is that real?" halfway, a face drifted 🙂

[Anshul Karasi @anshulkarasi]

@dani_avila7 extension is fine until you need a real terminal and a long agent loop. I still bounce back to CLI for anything that needs a kill switch 🙂

[Anshul Karasi @anshulkarasi]

@aimikoda sref locking the still is the easy half. Seedance keeping that ink look through motion without melting the silhouette is the real unpaid craft.

@me2resh Agents need a frozen task snapshot at spawn. Reading the live chat tip as the whole instruction is how you burn 310k tokens on nothing.

[Anshul Karasi @anshulkarasi]

@daniel_mac8 Cheaper tokens just moved the bill to orchestration. Cache TTL and subagent caps are the new cloud bill anxiety bro

[Anshul Karasi @anshulkarasi]

@Voxyz_ai The single-agent variance (14/15/27) is the story. Suite that hits 66 every time is what you can actually put in CI.

@TechieBySA Physical comedy is the hard part for AI video. Faces hold; the slapstick timing and prop contact still wobble. Bean winning that fight is the real flex 🍻

[Anshul Karasi @anshulkarasi]

@alsamahi Claude for long diffs when I'm picky about silence; Codex when I want speed and I already know the blast radius. Still put a human on the merge either way 🙂

[Anshul Karasi @anshulkarasi]

tl;dr
• price on screen is per unit
• cost = premium × 65
• OTM premium is pure time value
• cheap-looking isn't cheap

what's one options word you nodded along to for way too long? 🙂 (7/7)

[Anshul Karasi @anshulkarasi]

you see ₹100 next to a nifty option and think it costs ₹100.

it doesn't. it costs ₹6,500.

what a "lot" and a "premium" actually mean, in 6 tweets 🧵 (1/7)

[Anshul Karasi @anshulkarasi]

same contract, two very different jobs:

buyer pays the premium. worst case, it goes to zero.

seller collects the premium and posts margin that's far bigger. worst case can be a lot more than what they collected. (6/7)

[Anshul Karasi @anshulkarasi]

@AIwithYazdan Yeah, the badge trick works until the car turns and the light hits it from a different angle. Reference image locks frame 1. Continuity across cuts is still the edit.

[Anshul Karasi @anshulkarasi]

@prsablue calling timeframes camera angles is the most filmmaker-brained trading explainer I've read. most people just keep zooming in till the chart agrees with them 🙂

[Anshul Karasi @anshulkarasi]

@jurlycat make it write the tokens file first and diff that before it touches a single component. otherwise "preserve business logic" quietly turns into renamed props and a 40-file PR.
