• @elonmusk Elon Musk on x

  @nottombrown Same here. By way of background for those who care, I spent a lot of time last week with senior members of the Anthropic team to understand what they do to ensure Claude is good for humanity and was impressed. Everyone I met was highly competent and cared a great dea…

• @levie Aaron Levie on x

  SpaceX as a vertically integrated AI compute company makes an insane amount of sense.

• @mattzeitlin Matthew Zeitlin on x

  we always hear about frontier labs being compute constrained, why is xai/spacex giving anthropic access to their compute?

• @pitdesi Sheel Mohnot on x

  so many strange bedfellows in this business! Claude is scaling like crazy, and Grok / Colossus has a lot of capacity, so they are sharing with “Misanthropic”

• @emollick Ethan Mollick on x

  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.

• @benbajarin Ben Bajarin on x

  Doesn't sound like they are interested in dealing with the neoclouds.

• @obrien Chris O'Brien on x

  Glad to see xAI found a use for all that excess compute besides more deepfake nudes, I guess...

• @ashleymayer Ashley Mayer on x

  The enemy of my enemy is my compute friend 🥰

• @eliebakouch Elie on x

  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 [image]

• @dkthomp Derek Thompson on x

  Wow. The AI supply crunch is real. Frontier labs are desperate for compute. Musk has compute capacity but a meh model, and Anthropic has a fantastic model with weak capacity. Now I wonder if Elon continues to refer to his new business partner as “woke AI,” “Misanthropic,”

• @nottombrown Tom Brown on x

  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)

• @_sholtodouglas Sholto Douglas on x

  More compute -> straight to you

• @nickadobos Nick Dobos on x

  Claude just doubled its rate limits by partnering with SpaceX That was not on my bingo card. Especially after the cursor deal

• @fredlambert Fred Lambert on x

  Elon Musk went from saying Anthropic is “doomed” to selling it xAI's compute because it has no use for it. Are you starting to see it yet?

• @tunguz Bojan Tunguz on x

  Not so “mis"Anthropic any more it seems.

• @claudeai Claude on x

  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.

• @xai @xai on x

  SpaceXAI and @AnthropicAI have also expressed interest in partnering to develop multiple gigawatts of orbital AI compute capacity [image]

• @xai @xai on x

  SpaceXAI will provide @AnthropicAI with access to Colossus 1, one of the world's largest and fastest-deployed AI supercomputers, to provide additional capacity for Claude → https://x.ai/... [image]

• @alexeheath Alex Heath on x

  New: Anthropic will begin using @elonmusk's Colossus compute cluster. Was just announced onstage at the Claude Code developer conference this morning Ant is increasing rate limits across the board for the API and pro plans Ant has been very constrained and on the hunt for more

• @anildash.com Anil Dash on bluesky

  Now that Anthropic is partnering with xAI, let me bring back this post from a few weeks ago, and remind you: NO COOKIE FOR DARIO www.anildash.com/2026/02/27/ a...  [embedded post]

  New Compute Partnership with Anthropic and xAI

• @manan @manan on x

  enough people canceled their sub and moved to Codex that Claude can relax these restrictions

• @trq212 @trq212 on x

  We're winding back our peak hours limit reduction and doubling 5 hour limits. Excited to partner with SpaceX to bring you more compute and we'll keep pushing to bring you the best coding agent in the world.

• @edzitron Ed Zitron on x

  Anthropic loosening rate limits across the board by renting the entirety of Musk's Colossus-1 data center. Not really sure what the business strategy is here giving away $8-$13.50 for every $1 of sub revenue. Very funny. https://x.com/...

• @yuchenj_uw Yuchen Jin on x

  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. [image]

• @mweinbach Max Weinbach on x

  This is huge Anthropic doubled rate limits for Claude. Wow I think this puts it roughly in non-promo usage at the same price as OpenAI

• @claudeai Claude on x

  Effective today, we are: 1) Doubling Claude Code's 5-hour rate limits for Pro, Max, and Team plans; 2) Removing the peak hours limit reduction on Claude Code for Pro and Max plans; and 3) Substantially raising our API rate limits for Opus models.

• @claudeai Claude on x

  Our agreement with @SpaceX means we will use all the compute capacity at their Colossus 1 data center. This will give us over 300 megawatts of additional capacity to deploy within the month.

• Amol Avasare Amol Avasare on linkedin

  We've signed an agreement with SpaceX to use all of the compute capacity at their Colossus 1 data center in Memphis 🚀 …

• @minimaxir Max Woolf on bluesky

  The fine-print-omission from Claude Code's usage increase appears to be that weekly limits are *not* doubled.  The 5-hour rate limit shrinking was indeed an efficiency blocker that finally convinced me to cancel, but being only able to get 4 full sessions a week doesn't compell m…

• r/ClaudeAI r on reddit

  Higher usage limits for Claude and a compute deal with SpaceX

• @nvidia @nvidia on x

  Two frontier labs. One accelerated computing platform. Congrats to @SpaceX and @AnthropicAI on the new compute partnership, powered by 220,000+ NVIDIA GPUs inside Colossus 1. The future of AI runs on NVIDIA.

• @rondesantis Ron DeSantis on x

  Pro-human for the win. It's appalling how so many tech leaders are supportive or indifferent to the supplanting of the human experience by AI.

• @shaunmmaguire Shaun Maguire on x

  I think of @SpaceX as having 5 layers Layer 1: Launch Layer 2: Connectivity Layer 3: Compute / hyperscaler Layer 4: Applications / models Layer 5: Other bets (Terafab, Moon, pt to pt, etc) This partnership with @claudeai instantly derisks Layer 3

• r/wallstreetbets r on reddit

  Anthropic will get compute capacity from SpaceX

• @elonmusk Elon Musk on x

  @SawyerMerritt xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX

• @krishnanrohit Rohit on x

  @Dorialexander Cursor trains Grok 5 on Colossus 2? And if successful they expand capacity I guess.

• @dorialexander Alexander Doria on x

  just hit me: what happens with the cursor deal?

• @ramez Ramez Naam on x

  Re today's Anthropic/ xAI deal. SpaceX didn't need to buy xAI to become a space data center provider, selling compute to the highest bidder. The acquisition was a bailout of xAI.

• @jaminball Jamin Ball on x

  Some rough math! (All napkin math...) Assume Colossus 1 has 220k GPUs Assume 150k H100s, 50k H200s, 20k GB200s Pricing Assumptions: - $2.30 / hour for H100s - $2.60 / hour for H200s - $5 / hour for GB200s - blended rental rate across the entire fleet of $2.60 / hour Assume it's

• @scroogecap @scroogecap on x

  This is a catastrophic signal for neoclouds like $CRWV and $NBIS. These companies exist because compute was scarce. When someone like SpaceX enters the rental market with 220,000 GPUs at once, they become the 800lb gorilla. SpaceX has the advantage of vertical integration and

• @z Zach Brock on x

  congrats to anthropic for defeating grok in the market and feasting upon the compute of their fallen enemy
