Who here actually uses Grok? It's sad to see Elon's arc but when he doubled down on some of his political ideas he had it coming with the Tesla sales going down and x.ai not taken seriously. I've always tried to remain apolitical and unbiased but it's hard to overlook who's behind a technology you wanna buy. Not that sama and others are saints either, it's just Elon's very obvious and vocal about it. It's a shame, re…

Let me give you a perspective. For Indians Winston Churchill is no different than Hitler. The guy was responsible for millions of death in bengal famine.But for you and I assume majority of this forum and westerners he is a hero. Against Winston Churchill though Elon appears like a saint!

I think this is against HN’s policies. @dang

I thought exceptions tended to be made when its highly relevant to the technical topic at hand and also non controversial.

Outside a few weird online bubbles and pockets of the US, hardly anyone disputes the claim you are objecting to.

I don't think there are any up-to-date leaderboards, but models absolutely degrade in performance the more context they're dealing with. https://wandb.ai/byyoung3/ruler_eval/reports/How-to-evaluate... >Gpt-5-mini records 0.87 overall judge accuracy at 4k [context] and falls to 0.59 at 128k. And Llama 4 Scout claimed a 10 million token context window but in practice its performance on query tasks drops below 20% accur…

That makes me wonder if we could simply test this by letting the LLM add or multiply a long list of numbers? Here is an experiment: https://www.gnod.com/search/#q=%23%20Calcuate%20the%20below%... The correct answer: Correct: 20,192,642.460942328 Here is what I got from different models on the first try: ChatGPT: 20,384,918.24 Perplexity: 20,000,000 Google: 25,167,098.4 Mistral: 200,000,000 Grok: Timed out after 300s…

Isn't that LLMs are not designed to do calculations?

This post really has no reason to be flagged. I know Elon is controversial, and I have a lot of gripes with his business practices myself, but this is literally just documentation for a frontier LLM. Can we stay on topic?

Are you implying that avoiding use of services controlled by a fascistoid oligarch is cope?

Besides the obvious right wing interference in politics, star link weaponization in some countries - how can anybody stomach the saving-humanity-agenda while running a major social media unresponsiveliy without caring of moderation, its consequences for real people?

Because someone's moderation is censorship to someone else. Begging Musk for free speech is another issue in itself though so you better don't bet on X allowing you to speak forever.

Free speech is one of these things that is always used as a trojan for doing ultimate good.

Let us empower anybody to say anything they want AND enforce everybody to have to listen to it.

Anonymous free speech is not free speech. There is no accountability. It should not should not be a human right. Its destroying our societies. The evidence should be clear by now.

Thought this would be about the whistleblower. They didn't even mention it!

Yes allegedly having an employee bumped off for whistleblowing and the sister thing is way worse than someone having a different opinion than you. One is criminal the other is free speech.

One is alleged, other isn't just an opinion. Its estimated that several hundred thousand deaths have already happened from the abrupt USAID cuts initiated by DOGE.

I had a failed refactor with Codex recently and I am wondering if context window size is the cause.

I use Claude Code, haven't used Codex yet (should I?) - but in Claude code you can spin up sub-agents to handle these big refactors, with the master context window just keeping track of the overall progress, bugs, etc and providing instructions to the subagents to do the rote work.

IMO yes. It is less polished but IMO the model is way better. I moved over from claude completely and cancelled my max subscription. Less polished, slower but the results are better and you have to do less steering
