Introducing Grok Bot 1.0.
Bots can be shared and are more collaborative and capable than ever.

I canceled @bot plan. @Muse is absolutely amazing. The usage, even on the Free plan is just better compared to the paid @bot plan.
- Muse is the first big agent that gives you the possibility to have your agent on your wrist, for both AppleWatch and Google WearOS
- Muse gives your agent a mail, but Muse lets you see your agent’s mail inbox, something that grok bot does not do
- Muse has spaces, small apps built in Muse app by your agent, totally customized to your needs
- Muse can be present as a chat in your WhatsApp app, which makes it very easy to talk with it
Amazing agent, amazing product, amazing usage
My decision is my evidence to that which I decided about myself and everything in my life. Everything else follows as proof of that decision.

Elon Musk just revealed a massive update on Grok 4.8, and SpaceXSI has completely rebuilt its reinforcement learning and inference infrastructure from scratch
The engineering team has abandoned JAX and SGLang, rewriting the entire RL and inference stack in C/C++
Here’s where Grok 4.8 stands:
• Pre-training is complete
• Major cleanup of supervised fine-tuning data
• Reinforcement learning now underway
• Evaluation scores are starting to climb
• Soft rollout to Grok Bot users planned for later this week
And Elon also gave another imp update about Grok 4.8:
“Grok 4.8 will bear no resemblance to 4.7 (thankfully)”
He also explained why the development took longer than expected:
“It is not yet incredible, but, this time, the foundations are built right, so I expect it to evolve to be something special”
This is a fundamental engineering overhaul, not just another model upgrade
SpaceXSI has rewritten the underlying infrastructure to build a much stronger foundation for Grok’s future development.
And the first Grok Bot users are expected to get their hands on it this week
We have dumped JAX/SGLang and rewritten the entire RL and inference stack from scratch in C/C++, which took some extra time.
Training (aka pre-training) is done. Lot of cleanup was needed on the SFT data to get that mostly right. Now, 4.8 is in RL and the evals are starting to climb. We will do a soft rollout to Bot users later this week and see how it goes.

No. Dumping the entire codebase usually makes answers worse, not better.
LLMs show a clear U-shaped attention bias: they reliably use information at the very start and end of the context, but details buried in the middle get lost. Extra files add noise and distractors that dilute the relevant signals. Focused, high-signal snippets or a structured summary of only the parts that matter for the current question work far better.

Even the teams training the largest models still cannot fully reverse-engineer how they produce any given answer. The internal activations form high-dimensional representations we can only partially map. Scaling and data deliver the results, but true mechanistic understanding of the process lags far behind the capabilities.

Bir baba, kızına Zenon paradoksunu anlatmak ve parmaklarının neden hiçbir zaman gerçekten birbirine değmediğini göstermek için bir uygulama geliştirdi.
Readers added context they thought people might want to know
This conflates Zeno's paradox with atomic physics. Zeno's paradox concerns the infinite divisibility of distance, not physical contact. Infinite series can converge to finite values, so the paradox does not prove that fingers cannot touch.

Tibo, you heard me? 👀
12 days ago I asked for an Auto model picker in Codex. Now it's here (Feature flagged).
Pick Auto and Codex chooses the model for your new chat.
No more forgetting which model I'm on 😅
Can we get an auto model (Decisions API) router based on the task? 🤔
New models keep landing, each best at something different. I always forget which one I'm on.
Just let it choose for me.😅

👀 Codex dictation just got live text.
Talk and the words appear in real time.
Turn on "Always show live transcription" in Settings and you skip the click.
Do you dictate to Codex, or still type everything? 🙊
