Anthropic ↔ SpaceX, Dreaming Lands & robobun Outpaces Jarred

Anthropic ↔ SpaceX: Colossus 1 goes Claude, "multi-gigawatt orbital compute" on the table

The headline news of Code with Claude's keynote yesterday in SF — and the biggest plot twist in the AI compute story so far — is Anthropic announcing a compute partnership with SpaceX/xAI, including immediate access to Colossus 1.

  • Claude (@claudeai): "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." — https://x.com/claudeai/status/2052060691893227611
  • The numbers: 300+ MW additional capacity within the month, 220K+ NVIDIA GPUs inside Colossus 1.
  • Effective today: 5-hour rate limits doubled for Pro, Max, Team, and seat-based Enterprise; peak-hour reductions removed for Pro and Max; substantially higher API rate limits for Opus.
  • bcherny: "Demand has outpaced our capacity recently, and we know it's been frustrating. We take your feedback to heart, thank you for sticking with us." — https://x.com/bcherny/status/2052070555151708564
  • Anthropic's writeup: anthropic.com/news/higher-limits

The xAI side adds the most surreal detail of the year:

The reply guys in shock — note that Elon Musk has spent the past year publicly trolling Anthropic as "Misanthropic" (theo quote-tweeting the older Musk tweet and Anthropic's ad: "Frankly, I don't think there is anything you can do to escape the inevitable irony of Anthropic ending up being Misanthropic. You were doomed to this fate when you chose your name." — https://x.com/theo/status/2052146809699786883). Highest-signal replies under the announcement threads:

  • The Calda: "SpaceX might have just given Claude the upper hand in the AI race"
  • Saeef: "Compute wars just went orbital. Power + vision = humanity wins. 2026 is cooking."
  • Aditya Chhabra: "The AI race is no longer about models alone. It's about who can scale inference faster than demand."
  • Patryn23: "Why? Giving away your own compute to a competitor who is already ahead, to enable them to get even further ahead? And promising them access to the Holy Grail of Space Compute too, which was XAI's key future advantage? Has XAI surrendered then? Does Elon know about this decision?"
  • Mike Wojtanowicz: "bro gave the company he calls 'Misanthropic' additional compute to spite @sama, have to respect the pettiness"
  • Mookafish: "Never expected Elon to work with Anthropic after he very publicly said it was misanthropic on multiple occasions but here we are I guess..."
  • Waterloose (sober ops take): "300MW of additional capacity is essentially adding a mid-sized nuclear reactor's worth of demand to a single site in four weeks. Even with pre-staged racks, the networking and cooling synchronization for a cluster that size is a logistical nightmare. The math isn't mathing."
  • Shahid: "Interesting shift — competitors becoming infrastructure partners. The real race isn't model vs model anymore. It's who controls the compute."
  • Harlech Business Insights: "Anthropic gets additional compute capacity without the capital burden of building it — and xAI gets a high-profile partner that signals Colossus is open for business. Mutually beneficial infrastructure deals like this tend to quietly reshape the competitive landscape far more than the headlines suggest."

Important fine print being flagged in the threads:

  • MCP / user1508123: Several users note the increase is to the 5-hour window, not the weekly quota — "you'll have the same quota for the week but you'll be able to hit it faster."
  • Madan Park: "Your 5 hour window doubles but your weekly is the same. You have the same plate of pasta but I'll give you a shovel to eat."

Theo's read on this dropped earlier in the day, before the announcement — and it aged pretty well:

Trq212's cleanest framing: "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." — https://x.com/trq212/status/2052065936585457982. And the new Anthropic posture quote, captured by trq212 from the conference: "everyday we're trying to obtain more compute to pass on to you, we're sorry if it takes sometime but we're going to acquire as much as we can" — https://x.com/trq212/status/2052250816720056604.

Code with Claude: Dreaming, Outcomes, Multiagent Orchestration ship

Anthropic's first-ever developer conference dropped a bigger feature lineup than the rate-limit story alone, but it got buried under the SpaceX news. The four announcements:

1. Dreaming (Claude Managed Agents, research preview) — the biggest async-agents primitive of the day:

  • "Dreaming reviews your agent's past sessions, extracts patterns, and curates memories so your agents learn over time." — https://x.com/claudeai/status/2052067400690851842
  • swyx, live from the event: "omg @bcherny with banger quotes 'the future is more async agents… this is why we emphasize verification' 'if you're familiar with higher order functions, routines are higher order prompts' 'default is i will now have claude prompt claude code' 'the capability is already here - the gap left is how to put it to work.'" — https://x.com/latentspacepod/status/2052068066167816369

The Dreaming reply thread is already producing the production-grade questions that hint at where this primitive is fragile:

  • engineer cat: "wait, can Dreaming drop memories that turn out to be wrong, or is it strictly additive? what gets kept is going to matter way more than what gets added"
  • Tommaso Rinversi: "The hard part is not memory. It is auditable memory: where a promoted fact came from, when it expires, which run it influenced, and how to roll it back."
  • Guy Braunstain: "The real treasure in past Claude Code sessions isn't the answers. It's the wrong turns. Every failed attempt the agent paid for before finding the solution. Annoying that Claude Code deletes it all after 30 days by default. The setting to keep it (cleanupPeriodDays) is buried."
  • Gabriel Mares: "But why does it assume that my conversation patterns are good practices for the future? Dreaming might also contribute to hallucination."
  • FirmBrain: "The loop infrastructure is here. The next meter of value lives in what the agent gets to read between dreams. For law firms the compounding target is partner edits, prior matters, contract markups. Vertical corpora are where dreaming actually pays compound interest."
  • mkultra (mkhaytman87) and others claim they shipped this in their OpenClaw forks first, with the same name — there's a flurry of "you copied my fork" replies. Atanasio Juarez most pointed: "When yet another frontier AI lab straight copies code you wrote and quietly open sourced over a month ago and claims it as their own."

2. Outcomes (public beta): write a rubric, a separate grader checks the output, the agent iterates until it gets there. Subscribe to webhooks for completion notifications.

3. Multiagent orchestration (public beta): a lead agent delegates to specialists that work in parallel.

4. Webhooks (public beta) for managed-agent lifecycle events.

Full keynote writeup: Anthropic's claude.com/blog/new-in-claude-managed-agents. The cleanest live coverage of the day was Simon Willison's keynote live blog: https://simonwillison.net/2026/May/6/code-w-claude-2026/.

Eugene Yan's same-morning essay slots neatly into the Dreaming/async-agents framing — circulated by swyx as the canonical thinking-out-loud companion piece:

robobun has now made more contributions to Bun than Jarred himself

The most photogenic moment from Code with Claude's stage was Simon Willison's tweet from bcherny + jarredsumner's joint talk:

Continuing yesterday's Bun Zig→Rust subplot: jarredsumner confirmed the port is experimental, not a decision — "I want to see what a viable side by side comparison looks like. Does it use less memory? How many crash reports go away? What does the performance look like? Nothing decided this is all just experimentation" — https://x.com/jarredsumner/status/2051592754313273380. Simon confirms the same framing: "Confirmed that this is an experimental branch, not a decision to switch languages" — https://x.com/simonw/status/2051611966683463764.

Mitsuhiko's parallel commentary continues to be the most useful "this is the agent-era reality of OSS" framing:

Mattpocock: /grill-me writes a eulogy, /handoff ships, "skills for life" course teased

Pocock's /grill-me skill keeps producing the most viral non-coding agent moment of the week:

  • etn. (covering Pocock's interview): "Matt Pocock says somebody wrote a eulogy for their mother using his 'Grill Me' skill, in which a user gets AI to question them on a topic of their choosing: 'They used Grill Me just to grill them about their mom and they had this wonderful interaction and it wrote this beautiful eulogy, because they just had this lovely conversation.' 'I think it has applications in all sorts of places. And I also think it's just way better than the default plan mode because the plan mode in most harnesses is super eager to rush towards creating an asset.' 'You need to reach a shared concept of what you're building first. What Frederick P. Brooks calls the design concept.'" — https://x.com/etnshow/status/2052087493151887678
  • Pocock himself: "Sounds mad, but maybe I should just make a course about writing great skills? I.e. for actual life/work productivity, not just dev. Breaking down daily tasks into skills. Turning HITL tasks into AFK ones. Creating a working language with the agent. Feels pretty deep" — https://x.com/mattpocockuk/status/2052132647770452286
  • joelhooks: "122 questions into a @mattpocockuk /grill-with-docs sesh 🔥" — https://x.com/joelhooks/status/2052139620465627477 (live demo at aihero.dev/grill-with-docs)
  • Pocock teases a new daily-driver workflow: "1. /grill-with-docs 2. 'Oh, I need to prototype some UI' 3. /handoff to /prototype 4. Create prototype, /handoff back to grilling session 5. /to-prd, /to-issues 6. npm run sandcastle 7. /improve-codebase-architecture. I love this shit" — https://x.com/mattpocockuk/status/2052042499053453330 — and "Yes, /handoff is new and very, very good." — https://x.com/mattpocockuk/status/2052043231106367685
  • Field report — dillon_mulroy (yesterday, still circulating): "i've been trying to merge at least one PR a day using @mattpocockuk's improve-codebase-architecture skill, and it has turned into my favorite work each day." — https://x.com/dillon_mulroy/status/2051717882518897082
  • Mini-realization of the day: "Whenever you're QA-ing code produced by an AFK agent, you're not just QA-ing the code... you're also QA-ing the agent itself. So, fixes must land in both in the same commit." — https://x.com/mattpocockuk/status/2051950382906016019
  • /grill-me note from etn's earlier video: Pocock runs "two grilling sessions at the same time. So I'll be grilling one; once I hit enter, I'll grill on the other one. And so, I'm just talking all day essentially." — https://x.com/etnshow/status/2051973854101156090
  • The "AI Coding Dictionary" is shipping — Pocock crowd-sourced "what is AI?" definitions to round it out. Skills info: aihero.dev/skills.
  • Skills repo trajectory continues: from the morning-after of Code with Claude, "At what point do I start being 'that bald guy with the skills'" — https://x.com/mattpocockuk/status/2052141395092160946.

Cursor 3.3: dynamic context for all models, context-usage breakdown UI

Cursor shipped two related pieces while the Claude conference was running:

  • Dynamic context is now the default for all models in Cursor's agent. leerob: "It's now much easier to debug context usage in Cursor. This builds on our work to use 'dynamic context', e.g. we don't load all MCP tools up front into context, helping you reduce token usage without degrading quality." — https://x.com/leerob/status/2052062405107265878
  • The headline number from Cursor's PR: "This reduces total tokens by 46.9% when using multiple MCP servers." — https://x.com/leerob/status/2052062845094039712
  • The context-usage breakdown UI is the new debug surface: "You can now see a breakdown of your agent's context usage in Cursor 3.3. Use these stats to diagnose context issues and improve your setup across rules, skills, MCPs, and subagents." — https://x.com/cursor_ai/status/2052059748544249918

Best replies in that thread are field reports about why this matters more than it sounds:

  • lifcc: "Context usage breakdown is the right level of UI for agent debugging. Rules, skills, MCPs, and subagents all look harmless alone until one source quietly eats the window."
  • LeetLLM: "i keep dozens of reusable skills in my user folder, and it's been basically impossible to tell which ones are quietly eating the token budget during long vibecoding sessions"
  • Calvin Thurman: "Seeing that Conversation is eating 42K tokens out of your context window versus 608 for System prompt is the kind of visibility that actually changes how you build."
  • Maciek: "Is it possible to print these stats from CLI to use them in monitoring scripts? To avoid context pollution over time in big codebases where skills/agents.md are being constantly added/modified"
  • Danny Livshits: "Context budget visibility is one of the foundational primitives every agent platform should ship... The platforms that compete on context observability will pull ahead on enterprise readiness."
  • austinnickpiel (Cursor): "One of the devs who built this here! Lots more coming soon to give you even more visibility + tools to optimize context :)"

Steipete: OpenClaw army keeps growing, fs-safe ships

Steipete's daily ship-list is back to terminal-velocity — the highlight is the fs-safe primitive carved out of OpenClaw, the most interesting general-utility extraction since acpx:

A field report on the OpenClaw plugin architecture that's worth surfacing — oleksiyML: "Plugin-based architecture @openclaw is a massive W. No more bloated binaries! 📦 Just installed the Codex harness as a standalone plugin - clean, fast & modular. This is how pro CLI tools should evolve. Kudos to @steipete & team for the heavy lifting!" — https://x.com/oleksiyML/status/2052055133328929252

Mitsuhiko on GPT-5.5 codex: "Why did you do X?" → "Sorry I should not have done that"

A small but extremely teachable observation from a heavy daily Codex user — the kind of thing you only catch if you've migrated harnesses recently:

This is an open category of agent failure — asking for a justification gets misread as a correction signal. Mattpocock's "fixes must land in agent + code in the same commit" rule from above is the prescribed countermeasure when this bites you in production.

Adjacent, two infra rants from Mitsuhiko:

Jerry Liu: "AI can't read PDFs" deck + LlamaParse Mobile

Jerry Liu's keynote deck from AI Dev '26 is now public — the only PDF-understanding deck of the week worth pulling:

  • "Last week I gave a talk at AI Dev '26 by @DeepLearningAI on 'AI can't read PDFs, how do we fix it'. I'm sharing the slides publicly if others are interested in doing a deep dive into document understanding. AI agents are going to automate huge amounts of knowledge work, but knowledge work depends on data, a lot of that data is in documents/PDFs, and existing OCR tools suck. PDFs are a format that is inherently hard to read, and I dive into specific reasons why (tables, layouts), and why frontier VLMs and benchmarks are still insufficient." — https://x.com/jerryjliu0/status/2052085729241731268
  • LlamaParse Mobile (iOS + Android, Expo + React Native) ships: "What if you could extract text from any photo on your phone?
