A tinkerer recovered Claude’s true usage limits from a suspiciously precise decimal like 0.16327272727272726. This is very useful, because Anthropic really does not want to give me any useful information about the quantities of tokens my $20/month Claude Pro subscription is offering me before I run up against a limit and have to either switch out the models or pay API pay-as-you-go pricing: **CROSSPOST: SHELLAC: Suspiciously Precise Floats, or, How I Got Claude’s Real Limits** Two... 1/ Anthropic Related

The "whiteboard defense:" I should be able to pull you aside at any moment and ask you to explain any customer-facing system you've shipped. You should be able to clearly explain how it works and defend the decisions you made. This is my benchmark for responsible AI usage. I don't expect line-level familiarity with the code. I don't care if you remember the exact function name or implementation detail. You may not even know it. I don't care. But if I ask "why did you do X instead of Y?", "what happens if this actor behaves maliciously?", "what data structure did you use here and why?", or "wh… benchmarks Related

ok everyone, i took one for the team here's the data we all wanted to see - real token value of each LLM subscription, empirically measured through usage on my real subscriptions - supergrok heavy has now become the highest value at $12k worth of tokens (40x ROI) - the $200 plan from openai and anthropic roughly give the same amount of token value, $7k give or take - cursor ultra's ROI is the lowest among mainstream subscriptions, roughly half of OAI or Ant. for individual consumers i'm afraid this no longer makes sense to purchase this was done in a clean environment. i ran each provider acr… LLMs Anthropic Related

Thanks @jasonlk! Lot to do still but: 1) @linear is used by pretty much by all major labs/ai companies out there 2) our MCP traffic grows 50% MoM 3) we have the most agent integrations and active usage than any platform like this (3rd party, in-house agents) 4) our AI revenue (loops, coding sessions) has grown about 500% per quarter 5) we are closing several public companies/enterprises each quarter to help them coordinate their agent work Quoting @HarryStebbings The Bull Case for Linear Being a $100BN Company: "Linear is the clear winner.

I wrote a new essay about a strange inversion in AI-assisted programming. Old-school programming made sustained attention the scarce resource. You entered a tight loop with the machine, and the difficulty itself kept you engaged. Agentic coding changes that. To reach the same intensity, you keep more work in flight, run more agents, and consume more inference. Flow becomes throughput, then the usage meter appears. There are legitimate economic reasons for limits. But when higher plans are explicitly sold as freedom from interruption, uninterrupted access to your own momentum becomes the produ… kennethreitz.org

actually it turns out that you can significantly decrease power consumption with a very small reduction in overall compute. So if you if you've got like three really bad days in a row or something, you can actually just like you can dial back your power usage quite a lot without compromising your inference or or um or training.

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
