Key Highlights

  • Anthropic’s turbulent week continues: DMCA overreach hits 8,100+ GitHub repos before retraction, rate limits tighten during peak hours due to GPU shortage, and the company acquires biotech startup Coefficient Bio for $400M
  • The open-source imperative grows louder: Theo makes an impassioned case that closed-source developer tools are becoming untenable as AI accelerates both feature velocity and degradation — with Claude Code as the prime offender
  • AI compute economics shape the industry: Anthropic’s GPU allocation battles between research, product, and enterprise users expose the structural tension behind rate limit changes, while AI companies invest billions in natural gas plants to power data centers
  • Developer trust in AI continues to erode: Only 29% of developers trust AI outputs for accuracy (down from 40%), even as adoption climbs to 84% — a paradox that enterprise SaaS vendors must navigate carefully
  • Anthropic positions for political and market influence: New PAC formed ahead of midterms, private market valuations surge past OpenAI sentiment, and the All-In Podcast debates the Anthropic vs. OpenAI enterprise split

Analysis & Opinion

Anthropic Is Having a Moment in the Private Markets; SpaceX Could Spoil the Party — TechCrunch

Anthropic has become “the hottest trade around” in the secondary market for private company shares, while OpenAI appears to be losing investor interest. However, SpaceX’s anticipated IPO could redirect investor capital away from current private market favorites, potentially disrupting Anthropic’s momentum.

What the AI Trust Gap Means for Enterprise SaaS — Stack Overflow Blog

A paradoxical trend in developer communities: while AI coding tool adoption climbs to 84%, trust has plummeted — only 29% trust AI outputs for accuracy, down from 40% the previous year. More developers now actively distrust these tools (46%) than trust them (33%). For enterprise SaaS platforms, the article recommends scrutinizing where AI performs critical functions and evaluating how tools communicate uncertainty.

The Design of AI Memory Systems — Lobsters

A deep exploration of memory architectures for AI agents, from the author’s experience building Elroy — an open-source memory system used for three years as a brainstorming partner. The piece covers architectural approaches including MemGPT/Letta-style systems and argues that memory is “the most interesting subfield of AI,” as it transforms simple chatbots into something that retains context about your expertise, preferences, and conversational history.

Reaffirming Our Commitment to Child Safety in the Face of European Union Inaction — Google

Google, Meta, Microsoft, and Snap expressed concern over the EU’s failure to maintain legal protections for child safety detection technologies after a key derogation expired on April 3rd. The companies warn that “Europe risks leaving children across the globe less protected” and urge EU institutions to negotiate a new regulatory framework urgently.

Interviews & Conversations

I Got DMCA’d by Anthropic (Not a Joke) — Theo - t3.gg (16 min)

Theo recounts receiving a DMCA notice from Anthropic — not for the leaked Claude Code source, but for his fork of the official repo where he changed one word in one file. The notice targeted a network of 8,100+ repositories, most of which were innocent forks. Anthropic filed a retraction within hours, with employees saying it was a miscommunication with GitHub. Theo acknowledges the retraction but notes that filing false DMCA strikes is illegal under US law. He praises Anthropic’s team for their transparent crisis communication on Twitter — particularly Boris’s blameless postmortem of the leak (caused by accidentally shipping source maps via a manual npm deploy). Theo closes with his recurring argument: all of this could have been avoided by open-sourcing Claude Code.

We Need to Talk About the Claude Code Rate Limits — Theo - t3.gg (33 min)

A detailed analysis of Anthropic’s decision to throttle Claude Code during peak hours (5-11am PT), affecting ~7% of users. Theo explains the GPU allocation crisis: Anthropic must split a fixed compute pool between research (training new models like the rumored “Mythos”), product (background agents, code review), and users (subscriptions subsidized at up to 25x). The company was slow to invest in compute — both Anthropic and Google fell behind OpenAI in GPU procurement. Theo criticizes the communication: the change was announced after it took effect, only via a personal tweet from DevRel employee Thoric (not an official channel), with no specifics on the severity of throttling. One user reported 100% of their 5-hour limit consumed in a workflow that normally takes 10%. Theo contrasts this with OpenAI’s frequent, user-friendly limit resets for Codex. His conclusion: the compute problem is real, but Anthropic’s inability to communicate with users remains their fundamental weakness.

I’m Serious. — Theo - t3.gg (40 min)

An impassioned argument for why open source has become essential in the AI era. Theo’s thesis: when AI makes developers 100x faster, they can also degrade software 100x faster — making the ability to fork and fix critical. He shares the story of his intern Yash, who simply ignores boundaries between codebases, routinely patching dependencies and filing upstream PRs rather than working around bugs. This “patch-package mindset” has changed how Theo thinks about software ownership. He criticizes Cursor’s performance degradation and Codex’s instability, then reserves his sharpest critique for Claude Code — closed source, DMCA’d when accidentally leaked, while every competitor (Gemini CLI, Open Code, Codex CLI) has gone open source. He reveals that his tool Lawn (a YouTube production app) was forked by non-developers like Jake from XLT and Quinn from Snazzy Labs using AI to customize it for their businesses. His conclusion: the incentive to close source is growing at the same time that closed-source software is getting worse faster, and the only defense is open alternatives.

Anthropic’s Generational Run, OpenAI Panics, AI Moats, Meta Loses Major Lawsuits — All-In Podcast (80 min)

The All-In crew discusses Anthropic’s product momentum — from Opus 4.6 (“an inflection point” per Jensen) to Claude Code plugins triggering the “SaaS apocalypse,” with $6B in annual run rate added in February alone. Chamath notes Anthropic dominates enterprise (via 8090) while OpenAI owns consumer, and warns against creating false rivalry narratives since they recognize revenue very differently. Sacks raises concerns about Anthropic’s regulatory capture strategy (seeking government permissioning for chips and models) while praising their products. The panel debates OpenAI’s Sora shutdown, consumer AI monetization (Freeberg predicts subscription rates surpassing Spotify/Netflix), and Google’s structural advantage with existing calendar/email access. They also cover the new PCAST appointments (Sacks as co-chair, with Andreessen, Jensen, Zuckerberg, and Freeberg among members) and the intensifying US-China AI race.
