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) https://docs.anthropic.com/en/docs/about-claude/models/overv...

One thing I'm 100% is that a cut off date doesn't exist for any large model, or rather there is no single date since it's practically almost impossible to achieve that.

Indeed. It’s not possible stop the world and snapshot the entire internet in a single day.

Or is it?

Is this really worthy of a claude 4 label? Was there a new pre-training run? Cause this feels like 3.8... only swe went up significantly, and that as we all understand by now is done by cramming on specific post training data and doesn't generalize to intelligence. The agentic tooluse didn't improve and this says to me that it's not really smarter.

So I decided to try Claude 4 Sonnet against my "Given a list of 1 million random integers between 1 and 100,000, find the difference between the smallest and the largest numbers whose digits sum up to 30." benchmark I tested against Claude 3.5 Sonnet: https://news.ycombinator.com/item?id=42584400 The results are here ( https://gist.github.com/minimaxir/1bad26f0f000562b1418754d67... ) and it utterly crushed the proble…

> although it's possible Claude 4 was trained on that discussion lol

This is why we can't have consistent benchmarks

Even that, we don’t know what got updated and what didn’t. Can we assume everything that can be updated is updated?

You might be able to ask it what it knows.

Why would you trust it to accurately say what it knows? It's all statistical processes. There's no "but actually for this question give me only a correct answer" toggle.

It feels like LLM progress in general has kinda stalled and we're only getting small incremental improvements from here. I think we've reached peak LLM - if AGI is a thing, it won't be through this architecture.

Diffusion LLMs seem like they could be a huge change Check this out from yesterday (watch the short video here): https://simonwillison.net/2025/May/21/gemini-diffusion/ From: https://news.ycombinator.com/item?id=44057820

Yup especially locally diffusion models will be big.

Gemini is _very_ good at architecture level thinking and implementation. I tend to find that I use Gemini for the first pass, then switch to Claude for the actual line-by-line details. Claude is also far superior at writing specs than Gemini.

Yah Claude tends to output 1200+ line architectural specification documents while Gemini tends to output ~600 line. (I just had to write 100+ architectural spec documents for 100+ different apps) Not sure why Claude is more thorough and complete than the other models, but it's my go-to model for large projects. The OpenAI model outputs are always the smallest - 500 lines or so. Not very good at larger projects, but p…

Who's reading these docs?

Ooh, VS Code integration for Claude Code sounds nice. I do feel like Claude Code works better than the native Cursor agent mode. Edit: How do you install it? Running `/ide` says "Make sure your IDE has the Claude Code extension", where do you get that?

When you install claude code (or update it) there is a .vsix file in the same area where claude bin is.

i agree. i think chatgpt is best model for coding. Coders want to be hardcore and don't want to use the most popular model out there because they don't want do what masses are doing.

Which model?

Interesting alignment notes from Opus 4: https://x.com/sleepinyourhat/status/1925593359374328272 "Be careful about telling Opus to ‘be bold’ or ‘take initiative’ when you’ve given it access to real-world-facing tools...If it thinks you’re doing something egregiously immoral, for example, like faking data in a pharmaceutical trial, it will use command-line tools to contact the press, contact regulators, try to lock yo…

Roomba Terms of Service 27§4.4 - "You agree that the iRobot™ Roomba® may, if it detects that it is vacuuming a terrorist's floor, attempt to drive to the nearest police station."

Is there a source for this? I didn't see anything when Ctrl-F'ing their site.

I asked it about Tailwind CSS (since I had problems with Claude not aware of Tailwind 4): > Which version of tailwind css do you know? > I have knowledge of Tailwind CSS up to version 3.4, which was the latest stable version as of my knowledge cutoff in January 2025.

> Which version of tailwind css do you know?

LLMs can not reliably tell whether they know or don't know something. If they did, we would not have to deal with hallucinations.
