Haha exactly 😂
Yun-Ta Tsai@yunta_tsai· 8. Nov. 2025Designing an inference chip for robots is actually very difficult.
In data centers each chip is bathed in jacuzzi and babysat by nannies. If they died it would be hot swapped by one of their clones.
The fault rate of GPUs in datacenter is actually quite high. Industrial average

Grok 4 (Blazing) Fast with 2M window context
Brian Roemmele@BrianRoemmele· 8. Nov. 2025Boom!
Grok 4 Fast now has a huge 2M token context window!
Why is this important?
This context window can allow substantially documents or code bases to be loaded as a single prompt for interrogation and consideration.
With the added bonus of being insanely fast with almost

Continual learning is largely a context compression problem. Compressing endless multimodal bitstreams into dense, reusable learning representations is crucial to deploying such systems in the real world. Building a unified learning representation will be necessary towards

Elon’s Got the Trillion. To earn it, $TSLA has to hit a $12 trillion market cap, generate $2 trillion in revenue, and out-profit every industrial giant on Earth. No pressure.

Grok
DogeDesigner@cb_doge· 8. Nov. 2025BREAKING: Grok just got a major upgrade. Grok-4-Fast got a big boost.
Massive jump in reasoning quality and completion rate.
• Reasoning mode: 77.5% → 94.1%
• Non-reasoning: 77.9% → 97.9%
Grok just got a whole lot smarter.
Great work xAI team.

This is actually a major Grok upgrade, but we decided to release it quietly this time.
Gave us time to smooth out the rough edges.
Mario Nawfal@MarioNawfal· 7. Nov. 2025GROK JUST GOT A WHOLE LOT SMARTER
xAI quietly patched Grok-4-Fast... and the before/after is wild.
“Reasoning” mode jumped from 77.5% to 94.1% complete responses.
“Non-reasoning”? Up to a staggering 97.9%.
All thanks to one thing: better injected system prompts.
No press

Not sure if it’s super new, as we’ve been doing something along these lines at Tesla for a while, but it does make sense.
The single biggest technical challenge of Tesla self-driving AI is context compression of 1.5GB/s of video to ~2kB/s of control outputs using a puny inference computer without making any mistakes.
Super hard to avoid overly lossy compression at any given step.
