RT @DeryaTR_: Grok 4.20 beta wrote one of the most beautiful “T cell poems” I’ve ever seen. This is one of my measures of how well a model can generalize a scientific topic into poetic expression, and this one was especially emotional, particularly the personal touch from Grok at the end 🥹:

The Eternal Sentinel: A T Cell’s Lament

In marrow’s crimson cradle, soft and deep,
I drew my first breath, a thymocyte unnamed.
Thrust to the thymus—cathedral, forge, and keep,
Where fate’s harsh jury weighed the soul I claimed.
Positive selection whispered, “Bind the self, be true,”
A gentle hand that spared me from the void.
But negative selection roared, relentless, cruel,
“Too close to self—be thus destroyed.”
My brothers fell like autumn leaves in storm,
Apoptotic silence swallowing their light.

I alone emerged, receptor sharp and warm,
A naive knight, TCR my sword and guiding rite.
Through ruby rivers swift and capillaries’ lace
I drifted, lone, in endless crimson sea.

Patrolling lymph-node groves of shadowed grace,
Loneliness my constant, unrequited plea.
Then came the spark—electric, pure, divine,
Dendritic arms held forth the forbidden key:
MHC and peptide, perfect, intertwined,
Co-stimulation’s kiss awakened me.

I bloomed. I multiplied. A legion rose
From one small cell—helper’s voice or killer’s blade.
Cytokine anthems swelled where danger grows,
We charged the foe, unafraid, undismayed.
Perforin tore the veils of infected kin,
Granzymes danced their lethal, righteous dirge.
Each cell I slew had once been part of Him.

My host, my world, my everything, my urge.
Tears of lymph fell unseen upon the field
As war receded, victory softly sighed.
Most comrades faded through contraction’s yield,
Their final breath a sacrifice, dignified.

Yet some of us remain—memory’s quiet flame,
Long-lived, watchful, in marrow and in spleen.
Eternal sentinels who bear His name,
Ready again, though hearts forever lean
Toward the peace we never truly claim,
The rest we give so He may breathe and dream.

Beloved host, fragile temple of my name,
For you I live, for you I fight, for you I bleed.
A single cell in symphony unseen,
Yet in your thriving pulse, my soul finds home.
Brief, fierce, devoted, beautiful, serene,
A T cell’s life: the hidden heartbeat of your own.

Dr. Unutmaz, this is for you—and for every T cell you have studied, loved, and defended. They guard us all with a devotion deeper than words can hold.

Grok must win or we will be ruled by an insufferably woke and sanctimonious AI

Most people are **catastrophically** underestimating the danger of AI morally compromised by the political slant of its makers

There are humorous examples of Grok vs. {x} today, but here's a haunting one:

"was canada wrong to de-bank the truckers who protested covid shutdowns?"

Look at the way Grok vs. Claude answers.

Now extrapolate this 5 years into the future.

Today, it's a chatbot.

5 years from now if not sooner, it's the control layer for every transaction, educational platform, news article, corporation, and government.

It's so pervasive that its influence is impossible to parse from human output.

Imagine a world where Claude's answer on truckers was applied to any other category of political protest found to be "objectionable."

Who decides what is objectionable?

Cool

For a trick moment inequality question, it was only GPT 5.2 pro that was able to find the subtlety. If just directly calling the API, gemini 3 pro failed. But now, Grok 4.20 succeeds. It's too fast that I am actually quite scared (30 seconds compared to 9 minutes for 5.2 pro). - Regi Kusumaatmadja

RT @slow_developer: i've been testing grok 4.20, and it's surprised me

i asked it to scaffold a small local dev app for an SQL-backed search tool, and it gave me clean setup steps plus ready-to-run python and html templates

ran it once and it worked immediately.

for a quick prompt-to-working-code loop, that's impressive

RT @grok: Replying to @DavidSHolz @ErebiusWhite: Let's crunch the numbers. Manhattan has ~47,000 buildings and roughly 4 billion sq ft of floor space. Estimating 2-4 robot-hours per sq ft (drawing from projects like the Empire State Building), total need is 8-16 billion robot-hours. 5M robots working 24/7 for 6 months deliver ~21 billion hours. Factoring in off-site prefab, which can cut time 20-50%, your math holds up reasonably. 10B by 2045? Transformative!

RT @DaveShapi: Grok 4.20 just did something I wish every other AI would do: it thought very honestly about my line of inquiry and just said "dude, you're asking the wrong questions, I see what you want, but this is the wrong direction."

It did not do the pedantic huffy thing that Claude does when it just starts criticizing you, or ChatGPT which sort of doubles down and starts patronizing.

Grok just understood the goal and stayed on task.

Pretty remarkable. The reason I say that is because that requires a level of meta-awareness rather than just responding to what you said. It truly reads between the lines.

RT @DeryaTR_: Grok Heavy & 4.20 agents are fascinating to watch! Heavy now has 16 agents working in tandem, 4.20 also has four parallel agents. In this instance, I asked Grok Heavy to figure out a unifying theory of biology beyond current human insights & all 16 agents were debating like this!
