    The first chart in the blog post shows a similar $/performance curve to GPT 5.6. Where 5.6 has optionality to run much cheaper along the same performance curve at lower thinking le…

    GPT 5.6 is far more token efficient at most tasks with similar performance. Especially so for Opus 4.8, still to be seen with Opus 5. Where are you getting cheaper per dollar?

    Exactly. I've found 6 minutes or so the sweet spot for upper bound with 5.6 Sol. And it sounds like the OPs query above requires scanning throughout a large portion of the codebase…

    The hole can be filled overnight by just raising the retirement age. And if you normalize for longer lifespans, it's perfectly reasonable.

    When they can sell that for tens of Billions a year against competition, they might have a financial case. In reality, there will be many clones of Claude Design, especially if it …

    Then it's hard to switch? It's irrelevant the reason why, the margin any business can take will be constrained by the cost to switch to a cheaper, good enough, competitor. You are …

    Completely different levels of stickiness. The OS runs everything; the LLM can be swapped in a second. (But yes, you will have to tweak prompts+tuning anytime you change models)

    I say "human-like" in the sense that LLMs are fed in text data largely in the exact form (mapped to tokens) that humans read them. Thus from first principles it's most likely that …

    Information density of the interpretability of the intent from the perspective of a human (or human-like). If the intent is not easy to understand, it's information sparse. Because…

    Information density of the prompt is the most important factor in my experience. And interestingly, LLMs seem particularly bad at writing prompts for other LLMs for this reason (yo…

    You seem to be missing that if prices are lower, demand is lower. Price is a function of demand. If rents go from 10000/month at 100% occupancy to 5000/month at 100% occupancy, dem…

    Not much moat, incremental improvements, cherry picking models to compare. To be fair, seems more correct to compare against similar strength models if your main edge is pricing.

    The level of "slop" produced by AI is a direct function of skill of the developer and broadness of the prompts. Broad prompts by unskilled users results in a complete mess. Targete…

    Testosterone is directly causally inverse to bodyfat in men (once above some very low baseline) Fat directly converts testosterone to Estrogen via a process called aromatization. P…

    The main difference I'd guess is whether your prompts are targeted or broad. Less experienced people tend to use very broad prompts. Experienced people tend to understand the struc…

    Drop in rents is drop in demand, plain and simple. Fewer businesses want to invest and move into Seattle at the price it used to cost. It's true that if occupancy is poor, then a r…

    An increase in vacancies across the board is reduction in demand, plain and simple. That the new equilibrium price to re-tenant all the buildings is lower is evidence of that. But …

    It's about information density. Most LLMs by default seem to write both text and code with low information density. You can kind of get around it by prompting them to optimize for …

    AI is clearly a force multiplier, both negative and positive. The truth is there are prolific developers like Antirez who have built quality new projects at an incredible pace (Dwa…

    I'd like to see a world where the data vendor is separate from the app/UI product vendor. e.g. anyone could build a skin over map data, short form video data, long form video data,…

    There are hundreds of studies indicating that each marginal additional unit of bodyfat is less healthy for you than not having it. You are quoting poorly done and controlled BMI st…

    Yes it is but most of the studies use it, so that's the data we have. And the OP implicitly referenced these studies in his claim that being overweight could be healthier (which co…

    A 40-70m sustained effort is effectively LISS from a study perspective. The main distinction being made is intensity, and it's impossible to sustain even a marginally intense effor…
