An important note not mentioned in this announcement is that Claude 4's training cutoff date is March 2025, which is the latest of any recent model. (Gemini 2.5 has a cutoff of January 2025)

With web search being available in all major user-facing LLM products now (and I believe in some APIs as well, sometimes unintentionally), I feel like the exact month of cutoff is becoming less and less relevant, at least in my personal experience.
The models I'm regularly using are usually smart enough to figure out that they should be pulling in new information for a given topic.
It still matters for software packages. Particularly python packages that have to do with programming with AI!
They are evolving quickly, with deprecation and updated documentation. Having to correct for this in system prompts is a pain.
It would be great if the models were updating portions of their content more recently than others.
For the tailwind example in parent-sibling comment, should absolutely be as up to date as possible, whereas the history of the US civil war can probably be updated less frequently.
> the history of the US civil war can probably be updated less frequently.
It's already missed out on two issues of Civil War History: https://muse.jhu.edu/journal/42
Contrary to the prevailing belief in tech circles, there's a lot in history/social science that we don't know and are still figuring out. It's not IEEE Transactions on Pattern Analysis and Machine Intelligence (four issues since March), but it's not nothing.
Let us dispel with the notion that I do not appreciate Civil War history. Ashokan Farewell is the only song I can play from memory on violin.
this unlocked memories in me that were long forgotten. Ashokan Farewell !!
I didn’t recognize it by name and thought, “I wonder if that’s the theme for pbs the civil war…”, imagine my satisfaction after pulling it up ;)
I started reading the first article in one of those issues only to realize it was just a preview of something very paywalled. Why does Johns Hopkins need money so badly that it has to hold historical knowledge hostage? :(
Johns Hopkins is not the publisher of this journal and does not hold copyright for this journal. Why are you blaming them?
The website linked above is just a way to read journals online, hosted by Johns Hopkins. As it states, "Most of our users get access to content on Project MUSE through their library or institution. For individuals who are not affiliated with a library or institution, we provide options for you to purchase Project MUSE content and subscriptions for a selection of Project MUSE journals."
The journal appears to be published by an office with 7 FTE's which presumably is funded by the money raised by presence of the paywall and sales of their journals and books. Fully-loaded costs for 7 folks is on the order of $750k/year. https://www.kentstateuniversitypress.com/
Someone has to foot that bill. Open-access publishing implies the authors are paying the cost of publication and its popularity in STEM reflects an availability of money (especially grant funds) to cover those author page charges that is not mirrored in the social sciences and humanities.
Unrelatedly given recent changes in federal funding Johns Hopkins is probably feeling like it could use a little extra cash (losing $800 million in USAID funding, overhead rates potential dropping to existential crisis levels, etc...)

No it implied the journal not double-dipping by extorting both the author and the reader, while not actually performing any valuable task whatsoever for that money.
They could pay them from the $13B endowment they have.
Johns Hopkins University has an endowment of $13B, but as I already noted above, this journal has no direct affiliation with Johns Hopkins whatsoever so the size of Johns Hopkins' endowment is completely irrelevant here. They just host a website which allows online reading of academic journals.
This particular journal is published by Kent State University, which has an endowment of less than $200 million.
Isn’t john hopkins a university? I feel like holding knowledge hostage is their entire business model.
Pretty funny to see people posting about "holding knowledge hostage" on a thread about a new LLM version from a company which 100% intends to make that its business model.
I'd be ok with a $20 montly sub for access to all the world's academic journals.
So, yet another permanent rent seeking scheme? That's bad enough for Netflix, D+, YouTube Premium, Spotify and god knows what else that bleeds money every month out of you.
But science? That's something that IMHO should be paid for with tax money, so that it is accessible for everyone without consideration of one's ability to have money that can be bled.
