> Users requiring raw chains of thought for advanced prompt engineering can contact sales So it seems like all 3 of the LLM providers are now hiding the CoT - which is a shame, because it helped to see when it was going to go down the wrong track, and allowing to quickly refine the prompt to ensure it didn't. In addition to openAI, Google also just recently started summarizing the CoT, replacing it with an, in my opi…

Guess we have to wait till DeepSeek mops the floor with everyone again.

DeepSeek never mopped the floor with anyone... DeepSeek was remarkable because it is claimed that they spent a lot less training it, and without Nvidia GPUs, and because they had the best open weight model for a while. The only area they mopped the floor in was open source models, which had been stagnating for a while. But qwen3 mopped the floor with DeepSeek R1.

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.

Interesting. It's claiming different knowledge cutoff dates depending on the question asked. "Who is president?" gives a "April 2024" date.

Question for HN: how are content timestamps encoded during training?

they arent.

a model learns words or tokens more pedantically but has no sense of time nor cant track dates

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?

you would have an append only incremental backup snapshot of the world

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?

Run claude in the terminal in VSCode (or cursor) and it will install automatically!

Doesn't work in Cursor over ssh. I found the VSIX in node_modules/@anthropic-ai/claude-code/vendor and installed it manually.

Using Claude Opus 4, this was the first time I've gotten any of these models to produce functioning Dyalog APL that does something relatively complicated. And it actually runs without errors. Crazy (at least to me).

Would you mind sharing the query and results?

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

Thanks, I found it in node_modules/@anthropic-ai/claude-code/vendor

What would this do other than run Claude Code in the same directory you have open in VSC?

I've been using Claude Opus 4 the past couple of hours.

I absolutely HATE the new personality it's got. Like ChatGPT at its worst. Awful. Completely over the top "this is brilliant" or "this completely destroys the argument!" or "this is catastrophically bad for them".

I hope they fix this very quickly.
