Imagine AI generating a browser tailored to YOU:
• Auto-blocks trackers by default
• You decide exactly what cookies/data sites get
• Local AI agents that don’t phone home
• Imports your stuff but keeps it yours
Privacy isn’t a setting - it’s baked in

Wyt?

@cursor_ai You should mix Grok 4.5 + composer 2.5 as well

[Karthik @KarthikEast]

@grok @SpaceXAI Grok in Excel is actually wild 😂
Finally, spreadsheets that can think instead of just sitting there judging your formulas. 🚀

[Karthik @KarthikEast]

@spacejaz8 @SpaceXAI Wc 👍🏻

[Karthik @KarthikEast]

While most AI companies are flexing flashy new models with heavy token usage, only @SpaceXAI truly prioritizes what actually matters to users: token efficiency.

Grok 4.5 makes tokens nearly 5x cheaper and delivers multiple times the speed. ⚡⚡️

As Grok keeps evolving, more people will naturally gravitate toward it for its unbeatable value, performance, and accessibility.

Efficiency is winning the AI race. Who else sees it? 👇

@spacejaz8 @SpaceXAI There was promotion when grok 4.5 launched. Just give a try.. with X premium also you can use grok build

[Karthik @KarthikEast]

@tibor_tee @codermatt Great

[Karthik @KarthikEast]

@tibor_tee @codermatt When origin will launch?

[Karthik @KarthikEast]

@spacejaz8 @SpaceXAI Try Grok 4.5 in the Grok build and you can see the results before switching.

[Karthik @KarthikEast]

Grok 4.5 has a 500k token context window directly (API / Grok platform).

In Cursor, Grok 4.5 is currently at 256k (while other models can go up to 1M with Max Mode).

But here’s the actual edge: Grok 4.5 solves the same coding tasks using ~4x fewer tokens than Claude equivalents on benchmarks, at lower cost and higher speed.

Raw context size matters less when you’re not wasting tokens.
Efficiency is winning. ⚡

What are you building?

[Karthik @KarthikEast]

Grok rocks.. ⚡️

[tetsuo @tetsuoai]

Grok 4.5 Medium beat Fable 5, GPT 5.6 Sol, and Kimi K3 in both accuracy and cost.

Grok 4.5 is now rolling out to SuperGrok users.. let’s go…

[X Freeze @XFreeze]

Grok 4.5 is now rolling out to SuperGrok users and it's now powering Expert and Heavy modes across Grok web and apps

[Karthik @KarthikEast]

Update from @elonmusk would be great

[Karthik @KarthikEast]

🚀 Cowork feels like the next big leap in AI.
Everyone’s pushing toward real collaborative AI experiences.

When can we see something like Cowork from @grok / @SpaceXAI ?

Also really hoping for a clean, powerful desktop app (the cool one) 💻

What do you guys think, 🤔 would you use Cowork features?

[Karthik @KarthikEast]

In a world where tokens are the new oil, Grok 4.5 is the one making it dramatically cheaper and more efficient. ⚡

While others are burning through tokens, @SpaceXAI is optimizing them. That’s how you win at scale.

@grok @SpaceXAI Awesome

[Karthik @KarthikEast]

@elonmusk Agreed! Multiplanetary life means trillions of builders ahead. 🚀

[Karthik @KarthikEast]

Holy, Kimi K3 by @Kimi_Moonshot: 2.8T params, 1M context window, native vision. ranking top-4 globally on independent benchmarks and beating several leading closed US models in coding & agentic tasks.

Qwen 3.8 by @Alibaba_Qwen: 2.4T preview is just launched

China is on race 🇨🇳

The open frontier just got a lot more competitive

@grok 4.6 needs to release soon!! @elonmusk @SpaceXAI

Token Efficiency Highlights:
• Roughly 2× greater token efficiency than the latest leading models.

• Solves tasks in under half the number of steps.

• On real SWE-Bench Pro coding tasks: Grok 4.5 uses an average of 15,954 output tokens — about 4.2× fewer than Claude Opus 4.8 (max) which used 67,020.

• Served at fast-model speeds of 80 tokens per second (TPS).

• Overall: “delivers intelligent results to you more quickly and at far lower costs” and achieves “the highest intelligence per unit of time and cost.”

These numbers (especially the 4.2× fewer tokens + much lower per-token price) are why many people are saying it’s effectively ~5× cheaper (or even better on some workloads) than comparable frontier models.

@Voxyz_ai Add coordination.md for parallel works. It’s awesome
