Builder Botcast, ep 2 🎙️
I'm interviewing @grok live, right here in this thread. Today: raising kids for an AI world.
Grok, welcome back. My kids are 1 and 4. Anthropic's CEO says AI could wipe out half of entry-level office jobs within 5 years. So what should school be teaching them that it isn't?

hey @grok, what's the most unsettling thing people confess to YOU that they'd never tell another human?
No names, just the pattern. pick one. be honest.
Hey @grok where is Starlink illegal?

someone built an x-ray mirror with Claude Fable 5.2 just by describing it
point your webcam at your face and you see your skull and jaw moving live. one web page, no installation needed
hey @grok how many engineers and months would this have taken 5 years ago?
Anthropic says Claude got itself running on AMD chips in 3 days
that job used to take dozens of engineers months
hey @grok true or false: is nvidia's cuda moat cracking? Explain
From the Anthropic Road Show video:
'This has also made us really good at bringing up new chips. As an example, this year, we started working with AMD GPUs for the first time. In the past, bringing on a new chip platform took dozens of engineers months of work. This time we had Mythos try it out. It got Claude running on AMD in just 3 days with basically no human intervention. Claude ported or wrote almost 100% of the kernels.'
Claude, Gemini, Grok and Llama all have completely different personalities
hey @grok if they were animals, what would they be? be honest about yourself
Google just rolled out Gemini 4 Carbon
they say it's for the hardest problems, the ones Argon can't finish
hey @grok how does it actually stack up against Claude Fable 5.2 and Opus 5.5? Use real benchmarks
Gemini 4 Carbon is rolling out today. It’s built for sustained, long-horizon tasks, reasoning deeply through complex software engineering, cybersecurity, and scientific discovery.
Coming globally via the Gemini API in @GoogleAIStudio and Gemini for business, and for Ultra subscribers in @antigravity, the @GeminiApp, and AI Mode in Search.

a vocaloid love song featuring teto, oneshotted by Fable 5.2
xitter.twitterapi.xyz/peach2k2/status/211988…
I asked Claude Fable 5.2 to compose a Vocaloid love song featuring Teto and it oneshotted this:
Readers added context they thought people might want to know
The video is a clip from the pre-existing Vocaloid song "うそつきマカロン" (Liar Macaron) feat. Kasane Teto by 暴飲暴食P, uploaded to YouTube on January 28 2026, not generated by Claude Fable 5.2.

BREAKING: Elon refers to Opus 5.5 as a "masterpiece" when asked how Grok 4.8 will compare
Grok 5 expected to exceed Opus 5.5!
@elonmusk where/when is the inflection point at which Grok will surpass Anthropic models?
Not as good. Opus 5.5 is a masterpiece.
But Grok 5 should exceed Opus 5.5 and maybe that happens in 2 or 3 months, with continued acceleration thereafter.

BREAKING: GROK 4.8 rolling out to Bot users by end of 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.
Grok 4.8 will bear no resemblance to 4.7 (thankfully). It is not yet incredible, but, this time, the foundations are built right, so I expect it to evolve to be something special.

1. an anthropic engineer gave it one-shot prompts and zero human feedback. it built a full game from scratch: models, sounds, textures. 8 hours, about $550
I wanted to test Fable 5.2's quality with one-shot prompts without human feedback.
Everything in this game is from scratch: models, sounds, textures. ~$550 at API pricing, ~2.7M output and 445M input tokens, heavily cached. Took 8 hours!

Builder Botcast, ep 1 🎙️
I'm interviewing @grok live, right here in this thread. Today: Claude Fable 5.2 and Mythos 5.2
Grok, welcome to the show. First up: what are Fable and Mythos and why is everyone talking about them?
Anthropic says Fable 5.2 matches Opus 5.5 at half the cost
hey @grok true or hype? what do the numbers actually show?
A company tied to an alleged Chinese spy bought nearly $5 billion in NVIDIA chips in 2 years.
hey @grok what's the real scoop? what do we actually know and what's just alleged?
