There’s a certain freedom in no longer needing to understand everyone or be understood by them. Life is fleeting. Spend less time questioning what doesn’t resonate with you and more time appreciating what does.

You have an idea for an animated AI video, but aren’t sure how to create interesting characters.
Here’s a short guide on how you can use Grok Imagine to make your next character.

Here is the next-gen Tesla Roadster development video from the unveil event that they shared exclusively with us.

HERE IT IS. The Next Generation Roadster developed by SpaceX and Tesla!
There is a fan-suction system at the bottom of the car that can pull up to 2 gs allowing it to stick upside down.
It just flipped UPSIDE DOWN with cold gas thrusters and landed. HOLY SHIT.
Grok Voice 3.0 is now the world’s leading conversational voice model
SpaceXAI’s Grok Voice 3.0 is the new leading Speech to Speech model, debuting at #1 on the Artificial Analysis Speech to Speech Index at 86.9, while also being competitive on latency
Grok Voice 3.0 is @SpaceXSI 's successor to Grok Voice 2.0, a Speech to Speech model available through the SpaceXAI Realtime API at $0.08 per minute. We evaluated Grok Voice 3.0 with the Rex voice through the SpaceXAI Realtime API.
Key takeaways:
➤ Speech to Speech Index: Grok Voice 3.0 debuts at #1 at 86.9, ahead of GPT-Live-1 (Astra, medium) at 83.2, Gemini 3.8 Live Extended Thinking (High) at 82.6 and GPT-Live-1 (Sol, low) at 80.1. It is up on Grok Voice 2.0 at 81.3 (+5.6 points) and Grok Voice 1.0 at 73.7 (+13.2 points), released just under six months ago. The Index averages Speech Reasoning (Big Bench Audio), Agentic Performance (Tau Voice), Arena Preference, and Task Success Rate
➤ Speech Agent Arena: Grok Voice 3.0 ranks #3 in preference at Elo 1070, behind Gemini 3.1 Flash Live Minimal (1100) and Gemini 3.8 Live (1088) and ahead of GPT-Live-1 (Sol, low) at 1057, and #1 on Task Success Rate at 94.8%, highest on the board, just ahead of Grok Voice 2.0 at 94.6%. Grok Voice 2.0 trails at Elo 1011
➤ Tau Voice: Grok Voice 3.0 takes the #2 spot on our Tau Voice benchmark implementation at 71.6%, behind GPT-Live-1 (Astra, medium) at 74.5% and ahead of Gemini 3.8 Live Extended Thinking (High) at 68.6% and GPT-Live-1 (Sol, low) at 59.3% - up from 56.5% for Grok Voice 2.0
➤ Big Bench Audio: Grok Voice 3.0 scores 98.5% on audio reasoning, ahead of Gemini 3.8 Live Extended Thinking (High) at 97.7% and Grok Voice 2.0 at 97.2%
➤ Speed: Average Time to First Audio on Big Bench Audio is 0.81 seconds for Grok Voice 3.0, well ahead of GPT-Live-1 (Sol, low) at 1.24s, GPT-Live-1 (Astra, medium) at 1.34s and Gemini 3.8 Live Extended Thinking (High) at 1.35s, though slower than Grok Voice 2.0 at 0.70s
➤ Cost: Grok Voice 3.0 costs $4.80 per hour of input audio, the same as Grok Voice 2.0. That is above GPT-Live-1 (Sol, low) at $4.47 and Gemini 3.8 Live Extended Thinking (High) at $3.50, cheaper than GPT-Live-1 (Astra, medium) at $5.83, and ~2.2x cheaper than GPT-Realtime-2.1 High at $10.75

One plan now covers Cursor, Grok, Grok Bot, and X.
This is the biggest change to how Cursor is priced.
If you've been with us since the early days, this will feel like a lot, so I'll walk you through it.
First, every change is opt-in. If you do nothing, nothing happens.
You can keep your current plan with the same benefits, behavior, and pricing, and still move between the current plans. New sign-ups and anyone upgrading from free Cursor go to the new plans.
Here's what's different:
1. First-party usage
For most users, Grok and Composer coding limits are at least double what the matching Cursor plan gives you today.
We worked hard to make usage grow faster than price at each tier:
Plus ($8/mo): our base plan
Premium ($30/mo): 4x Plus usage
Super ($100/mo): 15x Plus usage
Ultra ($200/mo): 50x Plus usage
That's on top of every other product included in the plan.
On the new plans, Cursor usage limits move from monthly to weekly. Grok, Cursor, and X share one weekly pool.
All Grok Bot usage is treated as first-party. So on Premium and up, you get at least double the Grok Bot usage.
We know AI can get expensive. If you're trusting us, you should get as much as we can deliver. That's what we're aiming for with these new plans.
2. Products
Every paid plan includes X Premium features. Grok @Bot comes with Premium and up.
If you're reading this on X, you can now get those features as part of Cursor and @Grok. Your plan also covers Grok chat, Voice, and Imagine images and video.
Grok Bot access has been one of the biggest pain points we've heard since it launched, and it's a big part of why we're excited.
3. Third-party models
You can keep using every model you rely on in Cursor.
What's changing is how those models are billed on the new plans: they come out of your usage credits at the provider's API list price, the same as paying the provider directly.
Current Cursor plans subsidize third-party models, so you can get inference below API price.
At @SpaceXSI, we want to give you as much value as we can on our own models. That's why Grok usage limits are increasing and why we're treating Grok Bot usage as first-party.
We're still committed to Cursor being the simplest way to use models from many providers in one place, and we'll have more news on this front in the coming weeks.
If most of your usage is on third-party models, the new plans might cost you more, so check your usage before switching. That's one of the main reasons these plans are opt-in.
Cursor Pro and Pro+ subscribers who switch get Premium at $20/mo or Super at $60/mo for 6 months (normally $30 and $100).
4. Credit unification
Cursor credits and xAI API credits are coming together - prepaid xAI API balances now move into Cursor.
If you've been running the xAI API and Cursor as separate accounts, this is the start of managing both in one place.
It also means tools like Grok Voice become more accessible to all builders, and our biggest Grok users can now take full advantage of Cursor.
That's a lot of stuff! In summary:
Cursor, Grok, and X are all part of SpaceXSI.
That gives us economies of scale, and this unification is one of the main ways we can pass that on to you as savings and more usage.
Whether you should switch depends on which products you use, and that's different for everyone. If you pay for X today or most of your usage is on Grok, the new plans are probably a better deal.
To get started, check out cursor.com/pricing
What hasn't changed is why we do this: we want to build the best tools we can for you, and we think one plan across all of these products gets us closer to that.
If something here doesn't make sense or feels unfair, please let me know. I'm here to help.
