Image created with gemini-3.1-flash-image-preview with claude-opus-4.7. Image prompt: Using the provided reference images, keep the authentic Sonoran Desert trail setting, brown wooden post and weathered ranger-style sign from the references, but replace the header with bold all-caps ‘TWITTER’ and fictional trail entries like ‘← Subtweet Saddle 1.2 mi’ and ‘Ratio Ridge 3.4 mi →’ with a small bird-silhouette emblem in place of the WP3 medallion, and add a small flock of cactus wrens and one mockingbird perched along the arms of a nearby saguaro mid-chatter beside the sign. Maintain bright midday Arizona light, scattered volcanic rock, scrub brush, and the wide hazy Scottsdale valley in the background, fully photorealistic documentary style.
Anthropic is getting 220,000 Nvidia GPUs from SpaceX and has committed to spending $200 Billion on Google TPUs. Claude Code’s 5-hour rate limits are doubling. Dario is finally getting aggressive about chips from every possible source to fight OpenAI Codex’s growth.

Anthropic just announced a new partnership with SpaceX for additional compute. The company is upping usage limits by 2x for Claude Code across plans, removing peak hours reductions, and raising API limits for Opus.

Anthropic rents out the entire Colossus 1 datacenter from xAI / SpaceX with over 220,000 Nvidia GPUs including approximately 150,000 H100 GPUs, 50,000 H200 GPUs, and 30,000 GB200

Dario Amodei: We planned for a world of 10X growth per year. In the first quarter of this year, we saw .. 80X (annualized) growth per year in revenue and usage. That is the reason we had difficulties with compute

Dario&Daniela Amodei Interview: The 80x growth reportedly caught them completely off guard, and that’s the reason for the compute constraint. The compute deal with SpaceX is the first attempt to address the shortage and continues to search for solutions.

Elon’s making $500 billion off Anthropic SpaceX numbers on this ? $18.5 billion revenue gunning for $1.75 trillion IPO valuation 95x Price/Sales ratio Renting the GPUs to Anthropic ~ $5 billion in additional revenue x 95 = $475 billion in valuation credit for the IPO

Higher usage limits for Claude and a compute deal with SpaceX \ Anthropic
https://www.anthropic.com/news/higher-limits-spacex
In the next few days we’ll be ramping up Claude inference on Colossus. Grateful to be partnering with SpaceX here. We are going to need to move a lot of atoms in order to keep up with AI demand, and there’s nobody better at quickly moving atoms (on or off planet Earth)

not even 3 months ago Elon was rabidly chudposting at Amanda Askell now, all water under the bridge! (water goes into Colossus to be annihilated by Anthropic’s inference demand) Not evil at all! Highly impressive people!

Under-reported details of the xAI/Anthropic Colossus data center deal: Anthropic get Colossus 1 but xAI keep using the larger Colossus 2, Colossus 1 has a REALLY bad environmental record, and xAI just shut down a bunch of older models on 2 weeks’ notice

Very excited to be partnering with @elonmusk @SpaceX! Visionary engineering + Claude is going to be awesome, scaling is continuing for a long time!

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.

went under the radar with the spaceX <> anthropic compute deal, but those features make a ton of sense for power users and i’d expect them to become very important in the near future dreaming: better and more expressive memory i’d expect, with cross session context do detect

xAI has launched Grok 4.3, achieving 53 on the Artificial Analysis Intelligence Index with improved agentic performance, ~40% lower input price, and ~60% lower output price than Grok 4.20 The release of Grok 4.3 places @xAI just above Muse Spark and Claude Sonnet 4.6 on the

I usually avoid commenting too much on industry deals, but this one is fascinating. Certainly seems like a blow to the idea that Grok will remain a frontier model.

Grok 4.3 is a big regression from Grok 4.20 on Vending-Bench 2. It seems to have narcolepsy problems, preferring to sleep for multiple days in a row over taking actions.

https://x.com/scaling01/status/2049947798825529468
the main problem I have with the new Grok (I can forgive its small model smell things) is that $2.5/1M output probably rests upon the 11% utilization of Colossus. Electricity is a rounding error compared to depreciation of this hardware. It’s not that Elon has frontier margins
https://x.com/teortaxesTex/status/2050043500985557120
this isn’t just taking idle gpus or part of the cluster from xAI, this is “”ALL OF THE COMPUTE CAPACITY”” of Colossus 1 crazy

You know, for all the shit Elon gets, Grok 4 series is honestly improving nontrivially version by version. And now there are no <600B Chinese models that beat this 500B (Flash-Max beats 4.20). This cannot be said of… many other quickly iterating labs
