usaar333··on Sonnet 5.5
Per the charts, there is largely no point to using Sonnet 5.5 at high+ as opus low generally will give similar performance at similar or lower cost.

But Sonnet 5.5 at medium and below gives you a cheaper option at a performance worse than the lowest thinking Opus (low), which may be viable for "low intelligence" use cases.

Yeah that's not big tech. $1 trillion market cap is big tech or 30k+ employees.

This is upper end of mid sized.

No yc alum counts as big tech

Where's that stat from?

https://www.pewresearch.org/internet/2026/06/17/americans-an...

That's 30% positive on productive/informed, and only ~5% on hinders.

Whether you think AI will turn out bad (say by killing us all) is a different question from whether it is positive or negative at the moment.

This axiom not being true (and I'd bet against it) means your overall conclusion is false.

Tech workers get paid in equity and many in the semiconductor industry are making far far more than this a year with all the equity appreciation.

True, but it gets you higher accuracy. Gemini had the best aa-omniscience score

usaar333··on Claude Opus 4.6
Openai has; they don't even mention score on gpt-5.3-codex.

On the other hand, it is their own verified benchmark, which is telling.

usaar333··on Claude Opus 4.6
i'd interpret that as rounding error. that is unchanged

usaar333··on Claude Sonnet 4.5
Except it is sublinear. Sonnet 4 was 10.2% above sonnet 3.7 after 3 months.
usaar333··on GPT-5
No it doesn't. If it were even linear compared to o1 -> o3, we'd be at 2.43 hours. Instead we're only at 2.29.

Exponential would be at 3.6 hours

usaar333··on GPT-5: Key characteristics, pricing and system card
No, this is below expectations on both Manifold and lesswrong (https://www.lesswrong.com/posts/FG54euEAesRkSZuJN/ryan_green...). Median was ~2.75 hours on both (which already represented a bearish slowdown).

Not massively off -- manifold yesterday implied odds this low were ~35%. 30% before Claude Opus 4.1 came out which updated expected agentic coding abilities downward.

usaar333··on GPT-5
At this point the prediction for SWE bench (85% by end of this month) is not materializing. We're actually quite far away.
usaar333··on Claude Opus 4.1
No obvious gains I feel from quick chats, but too early to tell.

These benchmark gains aren't that high, so I doubt it is that obvious.

usaar333··on Startup equity is worth more than you think
> Firstly, if your prior is that every previous startup failed, what does that say about your future chances of success?

The prior is the market. It isn't sane to use your own prior experience. (Works both ways -- if your last startup did great, shouldn't assume next will).

> 4% of YC companies become unicorns. How many startups do you need to work for before you become part of the 4%? That number is not a feasible number of jobs for one lifetime.

The bar (and what the model is calculating) is Series A from top VC, not YC Seed funding. That significantly increases odds. Specifically, ~45% YC companies get Series A, so it's more like 10% chance of a YC Series A funded company becoming a unicorn (https://www.lennysnewsletter.com/p/pulling-back-the-curtain-...).

Model is change jobs every 18 months if not booming. A 1 in 10 chance is quite reasonable over a career.

I agree there is an issue with the event being too rare, but you can't just look only at modal returns. 2/3 chance of $0 (the modal return) and 1/3 chance of $10 million profit is still pretty good odds to work with.

usaar333··on Startup equity is worth more than you think
Why is modal return so important? You'll work more than 2 jobs
usaar333··on Startup equity is worth more than you think
It's a probabilistic model. It assumes (correctly) that the low probability of a home run times the home run's valuation is quite large ("expected returns" in the probabilistic sense).

> this argument reads to me like "the returns on a Powerball win are so much higher than your projected lifetime earnings that playing the lottery is a smart financial move".

That's stronger claim than it is making, but yes in a sense it is saying the lottery can be a good move because the expectation is large - that's what VCs do after all.

Note that all the model aims to do is value the equity package. If a public company is offering more than what this model values the startup equity package as (and this often is the case!), it isn't worth it financially to work at that startup.

usaar333··on Startup equity is worth more than you think
The value of the equity package is 4x higher than the FAANG equivalent equity package (at preferred/market pricing) - that's not the same as saying the shares themselves are worth that.

To sum up the arguments:

* Employment packages allow things a shareholder cannot do (functionally recall their investment), so the high volatility leads to higher package returns.

* FAANG equity grants (RSUs) are taxed at much higher rates

* Expected return is in fact higher on startup equity than FAANG equity (and you generally have no way to invest in the good startups directly aside from working for them).

usaar333··on Lina Khan points to Figma IPO as vindication of M&A scrutiny
I don't see why the market cap proves whether she is correct or not. You'd have to compare it to the counter-factual of what the value of a Figma subsidiary would be under Adobe today.

This is not obvious at all to me. Instagram (bought for $1B) is probably worth ~700 B of Meta's market cap.
