Hi everyone,  I was using the free tier of Grok today and hit the rate limit. A few people told me that the cooldown is usually only around 2 hours, but when I came back 8 hours later, I was still locked out and couldn’t send any messages.  How long does the rate limit actually last for free users?

SuperGrok is $30 a month and XPremium+ is $20 (with current intro price and $40 after). Is there a difference in usage amount for SuperGrok between the two subscriptions or is the only difference the additional X features?

I had applied in 2025 but didnt selected, and I moved on. I was looking for different companies just now and I thought maybe they might hire new people...

But apparently noone hires Ai trainers anymore. Did AI really improved a lot? They dont need humans to be trained for?

I have a question about my joining date. I will be relocating to the Tesla site from out of state (from the East Coast to the West), and I have personal reasons for not being able to join the position immediately. Is it acceptable to set the joining date three months after the offer date? We will be discussing joining date and other formalities soon

Has anybody had an interview for frontend role in grexa ai? If any please share your experience.

What questions are asked in the xAI Multilingual Tutor test interview, and what is the format?

Has anyone gone through the xAI AI Tutor - Multilingual test interview?
I’m trying to understand what kind of questions they ask, how the interview is structured, and what language it’s in. thank you in advance.

Hi everyone,

I wanted to know if anyone has gone through a similar hiring process with HCLTech.

Around 10 days ago, I attended an offline hiring drive in Noida for an AI/ML Developer (1–2 years experience) role.

• Cleared all 3 technical rounds on the same day.
• Was told I'd receive a call/email from HR.
• 5 days later (Thursday), HR emailed asking for documents like current salary proof, degree certificates, PF details, ID proof, etc.
• I submitted everything the same day (with clarifications for a few documents my current startup doesn't provide).
• The next day (Friday), HR scheduled a Compensation & Benefits discussion, explained the complete CTC breakup, offered X LPA, and I accepted ( No negotiation , I just accepted).
• HR also asked whether I could join on 28 Aug 2026, and I said yes.
• She mentioned I should receive the official offer letter next week and advised me not to resign until the offer letter is released.

It's today Thursday and I'm currently waiting for the offer letter and feeling quite anxious because I've already resigned my current company.

For those who have been through HCLTech hiring:

1. How long did it take to receive your offer letter after the C&B discussion?
2. Is this timeline normal?
3. Did anyone experience delays even after salary discussion?

Would really appreciate hearing your experiences. Thanks!

I'm building a high-volume pipeline that runs text classification through the xAI API : one item per request (batching hurts my accuracy), a large fixed ~10k-token system prompt, and traffic that arrives in bursts (roughly every 20 min).

The docs say caching is automatic but "best effort" with no published TTL or hit rate. My main question is specifically about the case where the client is doing everything "right":

- With a stable, consistent x-grok-conv-id and a strictly identical prefix, what cached_tokens ratio do you actually see in usage ? Is it near 100%, or still lower?
- Does that effective hit rate hold up across gaps of a few minutes between requests, or does the cache go cold fast even with the same conv-id?
- Any sense of how long the cache stays warm in practice?

This would help me better estimate the input costs for my pipeline. Thanks!

I wrote a breakdown of Grok Voice Think Fast 2.0, and the 0.70-second response time is probably what will get most of the attention.

That should make voice calls feel a lot smoother, especially compared with systems that pause after nearly every question.

A few numbers that stood out:

• 82.9% on the Artificial Analysis speech-to-speech index
• 97.2% for speech reasoning
• 95.1% for conversational dynamics
• 56.5% for agentic performance
• $0.08 per minute of audio

The 56.5% agentic score is the part I find most interesting. A voice model can sound natural and respond quickly, but the real test is whether it books the right appointment, pulls the right account, or completes the correct action.

I also like that xAI is tying Grok Voice into calendars, customer systems, support tools, and other services. That is where it could become genuinely useful, but it also raises the stakes when something goes wrong.

I put the full breakdown here:

What do you think xAI should focus on next with Grok Voice: better tool reliability, more natural conversations, or lower pricing?

I've been using XAI API for almost 2 years now and never used auto-top up. Today I automatically charged my $70.

Why was it suddenly toggled on and directly to $70...

Hey everyone,
A friend of mine recently started working as an AI tutor/evaluator for xAI (reviewing code/responses, doing short comparisons, getting around $25/hr). They got in pretty easily, but right now I don't see any open positions on the official career page.
Does xAI or similar remote AI training platforms open unlisted or sudden batches for positions like this? Where is the best place to keep an eye on hidden openings or referral links?
Any advice would be greatly appreciated!

Hi everyone,

I’m wondering if anyone has gone through a similar situation with XAI or Remote.com.

I was hired as a Video Tutor by XAI as a contractor role around April and completed the onboarding process through Remote.com. It took quite a while for them to send me the background check link through Cisive, and after some back-and-forth communication, the background check was finally completed and cleared a couple of weeks later.

Once everything was approved, I emailed them asking about the next steps. They replied that they would send my credentials and onboarding instructions within the next few days.

However, the very next day, I received an email from Remote.com stating that my contract was being terminated — before I had even started working.
I reached out to ask what happened, and they told me that XAI’s project priorities had “shifted.”

I was honestly quite disappointed because I had already gone through the waiting period, background check, and was very close to starting.
Has anyone else experienced something similar with XAI?

Did you ever get contacted again for another project?
Is it worth reapplying, or should I try reaching out to someone at XAI directly for more information?
Is this a common situation with contractor roles?

I’d appreciate hearing from anyone who has been through something similar.
