Ladies and gentlemen, today we're launching one of our biggest changes to 𝕏

Introducing Custom Timelines

This feature allows you to pin a specific topic to your home tab. With support for over 75 topics, you can dive deep into your favorite niche on X.

It's powered by Grok's understanding of every post with the algorithm's personalization—meaning every timeline is made just for you. And it works even better when it's a topic you already engage with.

This was a huge undertaking across many months, so we're excited for you take it for a spin.

We're giving early access to Premium subscribers on iOS (and Android coming very soon).

Entiendo que haya casos en los que sí resulte benefioso el uso de las redes sociales (muy concretos, según mi entender). Pero hay cuestiones subyacentes como falta de contención real, humana. Hemos recorrido un camino de mucha dependencia en estas aplicaciones. Esos "vínculos" que permiten las redes sociales tienen doble filo.

@chat @grok is there an XChat app in Android?

[Tulio Manfredi @ManfrediTu]

@Samsung How about privacy when using Perplexity? Will this be an optional feature that you can turn off completely?

[Tulio Manfredi @ManfrediTu]

@ThreemaApp When will be Perfect Forward Secrecy implemented in the new desktop app in Threema Private?

@mark_k @xai This post from @XFreeze explains that really well

Grok 4.20 Beta has 4 powerful new specialized agents, each bringing their own unique strengths

Here’s how it works:
Grok: Team Leader & Final Integrator
- Coordinates the entire team, selects the best strategies and tools, integrates all inputs, double-checks quality, and delivers the final polished answer

Harper: Research & Analysis Collaborator
- Digs deep into web sources, 𝕏, and documents to gather accurate information and provide clear, structured insights

Benjamin: Verification & Strategy Collaborator
- Focuses on fact-checking, spotting edge cases, exploring alternative angles, and keeping the reasoning tight and strategic

Lucas: Logic & Creative Collaborator
- Handles step-by-step logical analysis, technical breakdowns, and generates fresh creative approaches

This collaborative system delivers more accurate, comprehensive, and thoughtful responses

@mark_k How about the doctor using that AI to be more accurate with the diagnosis and having that good understanding?

@Starlink @grok Can I subscribe to Starlink Direct to Cell from Argentina?

[Tulio Manfredi @ManfrediTu]

@mark_k Even it is good in different aspects, the UX (mobile app, mostly) still is not mature. I find glitches on voice mode. That hurts a little the experience and prevents more users to use it more. But, if they polish the UX, I think it's a good candidate to be the main option.

@mark_k IMHO, wouldn't be that another step to the Dead Internet? In some contexts, it could be useful. But it always will be overused. I think I get your point, bet we should be careful.

[Tulio Manfredi @ManfrediTu]

@xfreeze That's a really nice feature. I used it for clarifications and it was really helpful. That's why this is becoming grokking.

Terrifying Reality of 2025

Financial sponsor built a prototype in 2 weeks during diligence on an AI-healthcare company.

Prototype outperformed the target’s core product in clinician testing.

Deal killed.

[Tulio Manfredi @ManfrediTu]

We have Grokipedia! Nice for grokking knowledge. Good to go for quick access to concepts. Then, if needed, you can get more support from @grok .

[Sawyer Merritt @SawyerMerritt]

NEWS: xAI has officially launched Grokipedia.

It is an open source knowledge repository available to the public.

@OpenAI How about the privacy? That's could be sensible information. How you take care?

[Tulio Manfredi @ManfrediTu]

Multimodality leads to richer context. More powerfull LLMs lead to better processing of that context. If we sum that we get the possibility of AIs that are becoming really agents/assistants, "understanding" the user and making interaction more natural.

Ari and team are super talented and we can't wait Sky x ChatGPT!

[Tulio Manfredi @ManfrediTu]

@DotCSV Va a controlar lo que accedas y lo que puedas acceder. Y, además, toda esa información la va a usar para alimentarse para "darte una experiencia personalizada".
O sea, me genera dudas el tema de la privacidad.
