@AlexFinn As long as the scaling law stays the same, the HW shortage will stay around as big players buyout all resources no matter how. It can only change as player like DS break through new growth law.

I wrote a short story about AI platform lock-in. It's fiction. Barely.

@sairahul1 If you don’t worry about cost, loop is pretty ok. If you back to leetcode BIG-O, you know loop is not going to get you pass the bar.😀

[Xiwei Zhou @ZhouXiwei]

@AlexFinn In reality the sub mode of that super star can not sustain the cost associations, which is turning point to think about stripped specializations.

@bcherny This is great feature, I was building a analytic app on top of it to see the hotspot to optimize, glad to see it’s coming to standard.

Full survey: 11 sections, real production data,
head-to-head on 3 evaluation scenarios, token
budget breakdowns, and where each framework
actually wins.

I surveyed 6 agent frameworks in production: OpenAI, Claude, LangGraph,
CrewAI, Google ADK, Microsoft.
The honest ranking most people won't tell you 👇

[Xiwei Zhou @ZhouXiwei]

Three gaps none of the frameworks have closed:

1. No shared memory across agents
2. Costs are invisible until you get the bill
3. Observability is bolted on, not built in

The next 12 months will be decided here.

@HuggingModels I don’t think @karpathy ever claims in that gist as second brain, instead, he shared it in a very abstract writing purposefully. But I do agree better memory system is indeed for agent. @cannyforge

@karpathy I think we're at the stage like pre-personal computer age, get parts and tools to build interesting things. It should move towards to a trustful and certify direction, as an average consumer wants to buy a reliable commodity and can hold accountability if anything wrong.
