<p>I've been thinking about this for about a year. In my head I've called it "context bombs", though that may not be super accurate.<p>Think back to the movie The Manchurian Candidate. Produce highly capable LLM models then give them away for free. Train them with key phrases/codes etc to perform nefarious actions later when those codes are present in some piece of ingested context.<p>There were a couple of papers written on the topic in 2018 (I think, I'll need to find them again) and there's been surprisingly little more work done on the topic since. At least from what I've seen.<p>I really love the use of local models over subscription services but personally I would never recommend using open weights models from certain sources in a commercial environment.</p>

<p>Since it was released Opus 5.5 has solved almost all the problems I've had with previous Anthropic models over the last year. On medium thinking level (default in Claude code) it's been remarkably more succinct and really good at understanding my questions and even anticipating my needs. Has been a markedly huge improvement over previous models and even had me commenting to a colleague the other day that if all advancement were to stop, it would be a useful tool for at least the next 5 years.<p>But over the last 2-3 days, it's started exhibiting some of the problems previous models presented. It's been making absurd assumptions without asking about my preferences. More definitively, in 3 instances I've had to either correct it on previous decisions that were made but it ignored. 2 times I've had to double check it on some quite obvious high level performance choices I've come to anticipate the model already understanding from prior experience, especially in the same project. At least twice I've had to call it out only get the remedial "you're totally right I should have done X instead".<p>Also to be clear, I'm not playing around with more advanced expensive models that fall back. This is all experience within a Pro plan using Opus 5.5 medium.<p>Anyone else been encountering weirdness?</p>

<p>I'm old enough to have been in the industry when Chrome launched. It was amazing. It was such a relief to move away from IE and all the arcane levels of details I had to remember back then to artisnaly get IE to behave like a moderately modern (for then) browser.<p>Chrome was fast, did the basic job of correctly rendering pages, and its js runtime was groundbreaking. Node.js was direct outcome of that revolution.<p>Now these days the only thing keeping me tied to chrome is finger muscle memory. The death of manifest v2 is the 2nd to last nail.<p>Honestly Opus 5.5 had gotten good enough I've been considering a project to have it build a new browser based on the open source Chrome and keeps the v2 in place. Just customize it specifically for my preferences and call it done. No more unexpected breaking updates. Just a browser that does its job and nothing else.<p>The problem is I use safari on iOS. Generally not a bad browser. Equivalent and superior to Chrome is certain aspects. I don't really need to run Chrome on my phone. Safari is good enough. However... for a local build only I use maybe it's possible.</p>

<p>Passing opinion, but I hope this isn't indicating a lean in direction to 90's era Apple now that Tim retired. Too many overpriced skews and non-core products that diluted the brand and led to their market shrinking.</p>

<p>so responses like "I've turned on the lights", but you're still standing in the dark. That's my anecdotal level of interactions with any Gemini model.</p>

<p>Look at it from a training data perspective. If the models' behavior is being trained on a large corpus of text from human interactions, then it should be expected that certain conversational queues will be picked up in the behavior of the models.<p>So saying please and thanks isn't anthropomorphizing the models, it's more simply using input patterns that get better outputs more aligned to the desired result.<p>It also has the benefit of reinforcing polite behavior among us, the humans. Side benefit, but it is a thing to consider.</p>

<p>I would definitely be more satisfied if claude code would stop with the "how's the session going" popups. I find it very distracting.</p>

<p>Back a few years ago with gpt3.5 building some RAG apps, I was consistently finding I would get better, more adherent responses when saying please and thanks during interactions. It was particularly noticeable in prompts where I needed the agent to maintain consistency around a described persona and allowed response range.<p>I don't think there's anything going on inside other than predictions. That being said, being nice never hurts.<p>If I'm mean to some people and nice to others, that just means I'm an a-hole. I don't wanna be that. Being kind all around helps me be a better person in the world. And in some cases with the robots, it helps as well.</p>

<p>The entire site looks like it was generated with Claude. 
The site hijacks scrolling.<p>I scanned through paragraph after paragraph of overbloated and repetitive descriptions of what and how RAG works compared to how "modern agents" need to access documents.<p>What I never saw at any point was whatever this "alternative to RAG" was supposed to be.<p>Honestly the entire body of copy feels like it was llm generated.</p>

<p>I don't understand why people continue to use em-dashes. As far I know, the comment system on HN doesn't offer them. And iOS and android don't make them a default. They aren't something normally used by humans because - is a keyboard option that's easier to use.<p>The usage of them immediately makes your commentary suspect. Either you aren't using the standard web interface to make a comment, you're using and odd 3rd party client, or its LLM generated.</p>

<p>Cyberpunk 2077:<p>> Gameplay Type: First Person Shooter Role Playing Game
Summary: A long anticipated release with eight years of development time, the game’s launch has been plagued with bugs and poor performance as well as decidedly mixed reviews. Regardless, the title offers gamers the largest open world cyberpunk universe thus far, so despite the rather uninspired art design and a plot that brings nothing new to the genre, this game is the best available to allow players to immerse themselves in a cyberpunk setting.<p>This is a very dated and seriously opinionated review.</p>
