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?

Grok is not LLM, it is “not-so-large-take-out-what-Elon-doesnt-like LM” - no documentation necessary :)

#283Who 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…
At least Elon is open about what he believes. Other CEO's hide behind corporate PR machines, how do you know they are not psychopaths.
Yeah he was really open about his salute eh soldier?

#284Any details on exactly how they accomplished this? longrope?
Re: Grok 4 Fast now has 2M context window
#285My experience with AI is that you generally want to keep your context as small as possible and this is only useful when your relevant context is actually 2m tokens.

#287What matter is not context or the recod token/s you get. But the quality for the model. And it seem Grok pushing the wrong metrics again, after launching fast.
I thought the number of tokens per second doesn't matter until I used Grok Code Fast. I realized that it makes a huge difference. If it take more than 30s to run, I lose focus, and look at something else. I end up being a lot less productive. It also opens up the possibility to automate a lot more simple tasks. I would def recommend people try fast models
If you are single tasking, speed matters to an extent. You need to still be able to read/skim the output and evaluate its quality.
The productive people I know use git worktrees and are multi-tasking.
The optimal workflow is when you can supply it one or more commands[1] that the model can run to validate/get feedback on its own. Think of it like RLHF for the LLM, they are getting feedback albeit not from you, which can be laborious.
As long as the model gets feedback it can run fairly autonomously with less supervision it does not have to testing driven feedback, if all it gets is you as the feedback, the bottleneck will be always be the human time to read, understand and evaluate the response not token speed.
With current leading models doing 3-4 workflows in parallel is not that hard, when fully concentrating, of course it is somewhat less when browsing HN :)

[1] The command could be a unit test runner, or a build/compile step, or e2e workflows like for UI it could be Chrome MCP/CDP, playwright/cypress, or storybook-js and so on. There are even converts toversion of TDD to benefit from this gain.
You could have one built for your use case if no existing ones fit, with model help of course.

I use Grok more than other LLMs. It’s built into X, so the use case of pressing the Grok button on a post to see an explanation for something I didn’t understand, or a fact check for something I doubted, or just more background on a subject, is by far the most frequently useful feature of AI in my day to day life.
People seem to nitpick a lot. Grok 3 came out in, what, March? Cost how many tens of millions to train? And you’re mad because it’s not open source yet?

I use Grok 4 Fast via API, cheap, fast and almost really well suited for data parsing/extraction, a lot better than Gemini 2.5 Pro for example.

Nothing you posted (from an almost two year old article btw) in anyway refutes the prior comment. Grok is significantly the most biased. Did you sleep through its continuous insertion of made up stuff about south africa? This is the same person who is trying to re-write an entire encyclopedia because facts aren't biased enough. A group has created an alternate reality echo chamber, and the more reality doesn't match…
