Grok @Bot https://t.co/xJ6TDgARDg

people who left @OpenAI, @spacexai, @stripe and @Tesla to build something new in stealth on X: 1/ @hyhieu226: ex-openai and xai technical staff, google brain researcher, imo silver medalist. 2/ @rochi5ha: 5 years engineering at rippling,…

95.4% accuracy and $5.63 per 1,000 correct tool calls sits right next to 95.4% accuracy and $1.50 per 1,000 correct tool calls on the same benchmark. Same task, same pass rate, 3.75x the bill. That's Claude Opus 5.5 and Grok 4.7 on Tirtha…

IT IS BECOMING F*CKING DANGEROUS: GROK BOT EATS GPT, CLAUDE, GEMINI, LLAMA, DEEPSEEK AND MISTRAL One prompt and Grok 4.7 reads X in real time, holds 500k tokens and bills $2 in / $6 out per 1M. I pointed the Grok bot at the other six. Here…

Four labs shipped a standing AI agent inside ten weeks of each other, and that's not a coincidence, it's a race nobody wants to come in fourth. Grok Bot opened early beta on August 11. Meta Muse launched September 8, free to start, with a…

Posted about several companies in recent times. You have a correction, and with it, an opportunity to revisit your research. Go back and check my feed to see the companies I’ve covered, or ask Grok for the list. The last part is the…

A hacking group called CyberCartel used a web of AI agents powered by models from companies including Anthropic, SpaceX and Chinese lab Moonshot AI to automate cyberattacks against more than 400 Latin American financial targets, according…

Great progress by the Tesla team! https://t.co/87bCDKyzOB

BOOOM 🚨 $TSLA's Q3 2026 update is out. Non-GAAP EPS came in at $0.48, ahead of the roughly $0.43 to $0.45 analysts expected 🔥 But the most revealing parts of the deck have little to do with EPS. They show a company steadily shifting its…

Q3 Shareholder Update → https://t.co/u0UcDOuMNa Highlights – FSD Supervised attach rate grew to over 75% of new vehicle deliveries in NA – Unveiled the next-gen Roadster – Record deliveries in Canada, Australia, Japan & Taiwan – Tesla Semi…

appreciate @pronounced_kyle's framing of "read" "write" access between digital and physical worlds. One of the fundamental challenges for automating manufacturing is to solve for the digital-to-physical "write" access and…

Congrats SpaceX team! https://t.co/L5dY4UFxT0

Picture circus-tent structures going up over a one-gigawatt construction site in New Albany, Ohio, built that way on purpose because tents cut deployment time by 70 to 80% versus permanent buildings. That is Prometheus, and it is already…

Old friends are the best friends. Jensen rocks. The Star Mind computer being co-engineered by SpaceX and Nvidia is far better than almost anyone expects and will reach volume production next year. Working with the incredibly talented…

🚨BREAKING: @Barclays says @ElonMusk could announce a merger between @Tesla and @SpaceX before December. The firm expects SpaceX to acquire Tesla in an all-stock deal, leaving Musk with roughly 37% ownership but about 56% of the combined…

OpenAI just lost the man in charge of its entire COMPUTE buildout. Sachin Katti, who led OpenAI's infrastructure and Stargate data center push, announced he is leaving to build something newm, his last day is November 15 and he will stay…

Robotaxi improvements https://t.co/zsM3I8BPru

Tonight I had two wonderful meetings with builders. @peterevoss, who is building an AI that is very different than any of the LLM companies are building. Learns more like a human being than any other. We talked at length about…

Digital Optimus stares at the screen and plays games just like a human---for Physical Optimus That's where Tesla and xAI's Digital Optimus is now, according to Elon Musk: about halfway through the Diablo campaign, good at Counter-Strike…

a16z's Alex Immerman, David George, and Sarah Wang on why a data center can lower your electricity bill: "It may seem counterintuitive, but a data center can help lower your electricity rate. A recent US study showed that for every 10%…

The US grid plans to add 86 gigawatts this year. Here's where it's coming from: - Solar: 43.4 GW - Batteries: 24.3 GW - Wind: 11.8 GW - Gas: 6.3 GW - New nuclear: 0 GW The AI labs are planning for hundreds of gigawatts. Solar is the one…

Excellent and thoughtful piece here. https://t.co/mjHueUXIIX

Left: Texas's grid only maxes out about 200 hours a year, roughly 2% of the time. Right: New data centers that agree to cut back during peak hours can skip the wait for more capacity. US grids could add 100 GW of them without building a…

"At the end of 2024, Texas' grid operator had 63 GW of large new customers in its queue. By this June, that figure reached 474 GW, more than five times record peak demand." "Then Texas hit pause." "Developers routinely spam requests across…

In plant floors and enterprise IT, safety never lives inside application logic. The operational risk with autonomous agents is granting write access to legacy systems that lack rollback paths. Guardrails belong at the deterministic…

Have a productive new week friends! A lot is happening on Base right now, but a few updates stood out to me. @StrikeRobot_ai had XLeRobot complete a 12-step autonomous workflow in simulation. @virtuals_io also showed Astra controlling a…

Important to use Grok 4.7 with our Build harness for the best results https://t.co/ppqui4HYMm https://t.co/fALqWHdAOF

Grok 4.7 works extremely well with our Build harness https://t.co/qeSIpwH1Jp https://t.co/NcXiUBoKDf

Grok 4.7 places @SpaceXAI as third, after Anthropic & OpenAI, for agentic coding. When factoring in that Grok is significantly faster & lower cost, it’s a great choice for your everyday workhorse. https://t.co/PxkMzHx3o5

Monday Morning Analysis: Grok 4.7 turns the frontier model race into an economics test https://t.co/kiuZ7QXLzb

🇺🇸 @Grok Imagine Image 2.0 has jumped 14 places to No. 4 on Artificial Analysis’ text-to-image leaderboard, reaching a 1,154 Elo rating. Developed by @xAI, it is now the highest-ranked model outside OpenAI on the leaderboard and sits on…

Grok 4.7 is a strong combination of intelligence, speed & low cost https://t.co/LXZXnua7lj

The bottleneck in agent costs just moved, and I don't think most people are measuring the part that actually got expensive. For a year, agent economics meant output tokens: what a model charges to generate text. TypeSafe just showed the…

FSD Supervised w/ Grok is a lot like having your own Robotaxi https://t.co/BygwDoHkNe

🇺🇸 Grok @Bot now lets users route outbound connections through their own local machine instead of the data center. This means that websites see requests coming from your personal IP address rather than xAI's servers. The feature helps…

Grok Bot now lets your route through your local machine https://t.co/O2iqCdNSMu

xAI skipped Grok 4.7 entirely and went straight to 4.8 at 2.5 trillion parameters. That version jump is not marketing. It signals a training stack reset. The real story: xAI built their model training infrastructure in C++. From scratch.…

Anthropic’s CEO admitted that the companies building superintelligence may be too powerful to govern themselves (Save this). Dario Amodei is saying that frontier AI could become too important and potentially too dangerous for a few private…
