I spend way too much time testing AI tools.
The good ones, the bad ones, the prompts that save time, and the workflows that actually help creators and founders build faster.
Follow for practical AI without the hype.
Anthropic's IPO could now raise more money than SpaceX ever did.
Bloomberg says the IPO plus a private placement could reach $90.4 billion. SpaceX's biggest raise was $85 billion. An AI lab is about to out-raise the rocket company.
The target valuation is back at $1.5 trillion. Shares priced at $70 to $78. Up to 825 million shares, about $64.4 billion from the IPO alone. Orders are running several times the shares on offer.
Seven founders are each selling about $250 million of stock. Each one keeps roughly $18 billion. Microsoft has already committed at least $47.2 billion through June 2033. New deals with Microsoft and Google top $10 billion.
People keep asking if AI is a bubble. The order book is answering with numbers that beat SpaceX.
When the lab raises more than the rockets, what exactly are we still calling a bubble?

SpaceX just donated 750 Starlink kits to children's homes in 16 countries. Nine of them in Africa.
The partner is Both Ends Believing. The work is digitizing children's records so families can be found and kids can go home.
14,678 views so far. Small numbers for a Starlink story, and that says something about what the timeline rewards.
A satellite network built for war zones and remote villages is now doing paperwork for orphans: records, matching, reunions.
750 kits. 16 countries. Kids going home.
BREAKING: SpaceX is donating 750 Starlink kits to help children’s homes across 16 countries, including 9 in Africa.
Working with Both Ends Believing (BEB), Starlink will help digitize children’s records, trace relatives & support efforts to reunite children with their families.

SpaceX just ordered enough solar factory equipment to build 100 gigawatts a year. From a German company called Singulus.
A rocket company buying solar panel factories. The pitch is a 'sentient sun' for something called Starmind.
3.9 million views, 3,084 replies, and the replies split the way they always do when Musk goes big: this is the future, or this is a press release with a poetry problem.
Rockets were the hard part. Now SpaceX wants the power source too. The company that puts things in orbit is buying the factories that catch the sunlight.
Is the sun the next thing SpaceX tries to own?
SpaceX has ordered 100 GW/year of HJT solar manufacturing equipment from Singulus in Germany.
This is for Starmind to create a sentient sun.

Anthropic's new MAMUBench runs against the whole multi-agent hype. One agent coordinating for everyone beat a team of agents, one per user, in all four test environments.
A shared API budget. A clinic calendar. Group food and travel bookings. A merged queue. The agents that each served one person kept stepping on each other. The single coordinator didn't.
Three of the four environments are now public benchmarks, tested on frontier models from Anthropic, OpenAI, and Alibaba.
Four environments, four wins for the coordinator. The team of agents lost every single one.
If you're building multi-agent systems, the bottleneck isn't the agents. It's who coordinates them. Are you building one agent, or a team?

Cybertruck production now runs through the end of summer 2027. The truck the timeline buried two years ago gets two more years on the line.
1.05 million views, 1,451 replies, and the replies split exactly the way you'd expect: flop or backlog.
Musk's own follow-up cut through it: sentiment and profit are two different things. A truck can be a punchline online and still have a waiting list worth building for.
Flop or backlog? The order book gets the next two years to answer.
In order to work through more of the Cybertruck order backlog, production will be extended through the end of summer 2027

Grok Bot 1.0 is live. Tag @bot in any reply and Grok answers right there in the thread.
273,000 views in minutes. The replies are already a war over what this does to X.
Search used to mean leaving the conversation. Now the answer shows up inside it, under the post you're arguing about.
Every reply thread on X just became a place you can ask Grok anything. The timeline is no longer just people talking.
Is that the end of the Google habit, or the start of bot answers flooding every thread?

Your MCP server is quietly taxing every prompt you send.
OpenRouter ran the same GitHub task on Claude Sonnet 5.5 four ways. CLI: 1,421 tokens, $0.0075. Default MCP with 46 tools: 59,417 tokens, $0.1274. Same task. 42x the tokens. 17x the cost.
With 91 tools loaded it hit 101,351 tokens and $0.2113. A Skill doing the same job: 3,315 tokens, $0.0118.
Every tool you load gets pasted into every prompt before your question even starts. Tool Search can cut the preamble under 600 tokens.
How many tools is your MCP server loading right now?

Anthropic shut the distillation door. Da7_Tech says Chinese models haven't moved since.
227,000 views, 160 replies. The replies are the fight, and Kimi K3.1 Pro keeps getting posted as the counter-example.
Distillation was a shortcut. Teams that treated it as one are fine. Teams that built their whole pipeline on it are going quiet.
The race didn't stop when the door closed. The shortcut did.
Anthropic shut the door on distillation and Chinese models haven't moved an inch since.
Sucks to say it but that's just the reality.

Tesla's Full Self-Driving just got approved in Finland. Rollout starts soon.
503,000 views in 21 minutes. Europe has been waiting on this one.
The US has had FSD for years. Finland is the first crack in Europe's wall, and the software didn't change overnight. A regulator said yes.
Which country approves next?

94.7% of Grok apps are sitting open on the internet. No login required. No hack needed. Just a default setting.
Claroc checked 37,571 Grok apps still online. 35,578 of them open to anyone with the link. About 650 to 800 hold private data.
The examples are not theoretical. An ICU briefing with patient lab values. A hospital group with a 3,500-person staff list. An attendance app with 18 accounts and plaintext passwords.
Grok's publish dialog defaults to 'anyone with the link.' Most builders never changed it. The leak is one dropdown nobody touched.
If you built anything in Grok, check your sharing setting tonight. What did you leave open?

Cursor just rebuilt Projects for multiplayer. Your teammates and their agents now share one workspace.
458,000 views in about 17 hours. Coding tools spent two years selling you a faster solo seat. The next race is who makes agents work in a team without tripping over each other.
One agent writing code is fast. Ten agents in one workspace, editing the same files, is a coordination problem dressed up as a feature launch.
Does multiplayer make AI coding better, or just busier?
Your agents can now coordinate with your teammates’ agents.
Projects has been rebuilt for multiplayer: every teammate and their agents can now work together in one unified workspace.

Mississippi just reaffirmed the permit for a 1.2 gigawatt power plant in Southaven. 41 permanent natural gas turbines, built to feed xAI's Colossus.
Two days of hearings. Local opposition showed up. The regulators approved it anyway.
30,000 views in about 3 hours. People are watching because the pattern is now obvious: the AI race is being decided by who can get power plants permitted, not who has the best model.
A year ago the fight was over GPUs. Now it's over gas turbines and zoning hearings.
Who wins the next round, the labs with the models or the states that say yes to the power?
BREAKING: SpaceXSI scores a regulatory win as Mississippi upholds permits for its Southaven power plant.
• After two days of testimony, state regulators reaffirmed their earlier approval on November 10.
• The project includes 41 permanent natural gas turbines to power SpaceXSI’s expanding AI data center operations.
• The decision keeps the plant’s permits in place, a positive step for the energy infrastructure supporting SpaceXSI’s growth.

Bezos says the bottom 50% of earners in America should pay zero income tax.
His example: a nurse in Queens making $75,000 a year pays $1,000 a month in taxes. Twelve grand a year, from a nurse.
343,000 views in about 2 hours. The zero gets the headline. The $1,000 a month is what people actually feel.
A billionaire arguing the poorest half should pay nothing. The nurse's $1,000 a month is the part nobody in the replies can argue away.
Should a nurse on $75K really pay $12,000 a year while the bottom half pays zero?
🚨🇺🇸 WOW! Jeff Bezos wants the bottom 50% of American earners to pay ZERO taxes...
And he has a question for Washington:
“Why is a nurse in Queens making $75,000 a year paying $1,000 a month in taxes?”
Bezos argues that the bottom half of earners contribute just 3% of tax revenue anyway.
His solution? Stop collecting it from them entirely.
“We shouldn't be asking this nurse to send money to Washington. They should be sending her an apology.”

Starlink upload speeds are up 42% year over year. Median US upload, and every one of the 50 states improved.
Upload was always the punchline about satellite internet. Download was fine. Upload was the part that made video calls stutter and cloud backups crawl.
19,500 views in under 3 hours. People notice when the weak link stops being weak.
Fiber still wins on paper. But Starlink keeps closing a gap that was supposed to be permanent.
What does your upload speed look like right now?
BREAKING: Starlink’s U.S. upload speeds jump 42%, with improvements in all 50 states.
Ookla’s new report shows major progress for Starlink, comparing the first half of 2026 with the same period in 2025:
• Faster uploads: National median upload speeds rose from 14.63 Mbps to 20.73 Mbps, improving in every state and Washington, D.C.
• Faster downloads: National median download speeds increased 12% to 119.71 Mbps.
• Lower lag: Latency improved in 49 states and D.C., making connections more responsive.
• More states below 40 ms: 24 states recorded median latency under 40 milliseconds, up from just 10 a year earlier.
• More users reaching broadband speeds: 40% of U.S. Starlink Speedtest users achieved at least 100 Mbps downloads and 20 Mbps uploads, up from 18.9%.
• Winning customers: Around 9 in 10 new Starlink users tracked by Ookla switched from connections such as cable, DSL or fixed wireless.

SpaceX just won a $9.9 million Pentagon contract. For lasers.
Not rockets. Lasers. The Pentagon wants SpaceX shooting light, not just launching satellites.
26,000 views in about 2 hours. The rocket company keeps collecting jobs nobody expected it to do.
A decade ago SpaceX was the outsider begging for launch contracts. Now the Pentagon hands it laser work.
At this rate, what part of the defense budget doesn't end up at SpaceX?
BREAKING: SpaceX wins a $9.9 million Pentagon deal to study Starlink’s space lasers for missile-warning and tracking satellites. 🇺🇸
• The Space Development Agency will evaluate SpaceX’s “Plaser” laser technology, originally developed for Starlink.
• These lasers send data between satellites, potentially helping relay critical information about missile threats.
• SpaceX will provide hardware for evaluation and support efforts to integrate the technology into missile-warning and tracking systems.
• The contract could reach $12.7 million if additional options are exercised.
• Work is scheduled to finish by October 7, 2027.

CoreWeave just told the market demand for compute is 10x supply.
Their 2028 capacity interest is already several times what they have today. They raised prices 25% in July, then another 10% in Q3. Customers paid anyway.
259,000 views in 9 hours. Everyone in AI already knew the shortage was real. Now the shortage has a price tag.
The bubble debate misses the point. You can't call it a bubble when sellers keep raising prices and buyers keep lining up.
When does the shortage end?
You heard 10x demand for compute > supply from $CRWV today.
Hearing from $TSM today on Nikkei Forum:
"The demand on our leading node [most advanced] silicon is insatiable"
Customers "want to get [their] hands around any compute capability they can have. It's truly an insatiable environment."
Q: Whether AI demand was slowing?
A: "we did not see any sign of slowdown"
Q: How demand compared with TSMC’s ability to supply
A: "the demand actually is still far above our capability today to supply."
TSMC identified power and substrates as bottlenecks customers were encountering.
On the mid-to-high-50s annualized growth estimate for AI accelerator revenue from 2024 to 2029. Wei said "it probably will be higher."
Describing things as "insatiable" from a traditionally conservative company... doesn't quite look like any collapse in AI demand.

OpenAI pulled in $10 billion of revenue last quarter. Up about 50% in three months.
Its adjusted operating loss in the same quarter: $10.9 billion. Bigger than the revenue.
The loss was $10.1 billion the quarter before. Sales are compounding. So is the burn.
Everyone argues about whether AI is a bubble. The weirder truth is the biggest AI company on earth is growing 50% a quarter and still can't pay its own bill.
At this pace, how many quarters until the math has to work?

Apple built an app that turns your Mac into a private AI server. Open-weight models, on your own hardware, data never leaves the desk.
Then Apple pulled it from the App Store the same day it surfaced.
513,000 views in 18 hours. People want this badly enough to notice the second it disappears.
Apple sells privacy as its whole brand. So why is the one app that actually delivers it the one it won't ship?
Apple is working on a new app called Harbor
Harbor turns your Mac into a private AI inference server. Run open-weight models locally on Apple silicon—your data never leaves your hardware, and nothing reaches the cloud. Connect multiple Mac computers over Thunderbolt 5 to pool unified memory, enabling large models and higher concurrency that a single computer can handle alone.
Set up in minutes, not hours Harbor automatically detects your devices over Thunderbolt 5 to form a cluster. Plug in, start, and you’re running—no manual configuration, no command line, no infrastructure expertise required.
Download and run models directly Browse, download, and load open-weight models from within the app. Harbor handles model management so you can focus on the work, not the setup.
Cluster for scale Connect two or more Thunderbolt 5-capable Mac computers and Harbor pools their unified memory into a single inference resource. Run models that exceed any single computer’s capacity, or serve more concurrent requests across your cluster.
Harbor is currently in a private preview under the Claris brand.
