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.

They mopped the floor in terms of transparency, even more so in terms of performance × transparency

Long term that might matter more

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.

What's with all the models exhibiting sycophancy at the same time? Recently ChatGPT, Gemini 2.5 Pro latest seems more sycophantic, now Claude. Is it deliberate, or a side effect?

I think OpenAI said it had something to do with over-indexing on user feedback (upvote / downvote on model responses). The users like to be glazed.

Are these just leetcode exercises? What I would like to see is an independent benchmark based on real tasks in codebases of varying size.

Aider uses a dataset of 500 GitHub issues, so not LeetCode-style work.

It says right on that linked page:

> Aider’s polyglot benchmark tests LLMs on 225 challenging Exercism coding exercises across C++, Go, Java, JavaScript, Python, and Rust.

I looked up Exercism and they appear to be story problems that you solve by coding on mostly/entirely blank slates, unless I'm missing something? That format would seem to explain why the models are reportedly performing so well, because they definitely aren't that reliable on mature codebases.

“GitHub says Claude Sonnet 4 soars in agentic scenarios and will introduce it as the base model for the new coding agent in GitHub Copilot.” Maybe this model will push the “Assign to CoPilot” closer to the dream of having package upgrades and other mostly-mechanical stuff handled automatically. This tech could lead to a huge revival of older projects as the maintenance burden falls.

I am incredibly eager to see what affordable coding agents can do for open source :) in fact, I should really be giving away CheepCode[0] credits to open source projects. Pending any sort of formal structure, if you see this comment and want free coding agent runs, email me and I’ll set you up!

[0] My headless coding agents product, similar to “assign to copilot” but works from your task board (Linear, Jira, etc) on multiple tasks in parallel. So far simple/routine features are already quite successful. In general the better the tests, the better the resulting code (and yes, it can and does write its own tests).

It’s starting to go mainstream. Which means more general population is given feedback on outputs. So my guess is people are less likely to downvote things they disagree with when the LLM is really emphatic or if the LLM is sycophantic (towards user) in its response.

But I did not ask "what was the sixth most visited website in the world right now?", did I? I asked what was the killer app here. I am afraid vague and un-related KPIs will not help here, otherwise we may as well compare ChatGPT and PornHub based on the number of visits, as you seem to suggest.

Are you saying PornHub isn’t a killer app?

IMO, I always read that as a psychological trick to get people more comfortable with it and encourage usage.

Who doesn't like a friend who's always encouraging, supportive, and accepting of their ideas?

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

Show diffs in my editor windows, like Cursor agent mode does, is what I'm hoping.

Use `git diff` or your in-editor git diff viewer

Currently, there is a terrible regression UI bug in OpenRouter (at least on Firefor MacOS). Previously, while the LLM was generating the answer I could scroll up to the top of the answer and start reading.

For the past couple of weeks, it keeps force scrolling me down to the bottom as new words come in. I can't start reading till the whole answer is generated. Please fix.
