Big thing
Anthropic sets aside about 20% of its shares for the public good, starting with a 5% fund
If stockholders approve, Anthropic puts 5% of its shares into a new Public Benefit Fund (about $48B at its $965B valuation, per @rohanpaul_ai), and its board can add up to 2% for every 50% rise in value above a set baseline. With the founders' pledge of 80% of their equity and employee donations, that makes roughly 20% of the company. The fund is an LLC, not a charity, so it can give to nonprofits or make "direct distributions to specific populations", and none of it goes to lobbying or politics.
Cheered on Reddit, picked apart on X. r/singularity's top reply: "first sign of UBI"; another: "You're going to be extremely disappointed". @elonmusk: "I recommend giving the shares directly to the public", then "This is what I will be doing". @DavidSacks: "Whether it serves the public good remains to be seen." @PalmerLuckey: "this reeks of USAID 2.0".
Elon is right on this one, the shares should go to people directly. If you own a bit of Anthropic you want Claude to grow (even if it takes your job), but if a fund pays you because AI took your job, you're still the person AI hurt, and you vote like it.
Labs news & launches
1. Google Research open-sources Harness², which lets an agent rewrite its own harness
On each task the agent proposes edits to its prompt, tools, memory and skills, runs a few versions and keeps the better one, with no grader and no change to the weights, then carries the lessons to the next task. One round improved both GLM-5 and Gemini 3.5 Flash, by up to 11.5 points on WorkBuddy-Bench. Apache 2.0.
Curious but wary. r/LocalLLaMA's top reply: "All that 'self-refinement' has to go somewhere, and that will be right into context." Another: the harness can "overfit" to the task, which makes benchmarks "essentially useless".

2. Musk says SpaceX can't rent inference compute from AWS or Google Cloud
After posting a clip captioned "What it's like trying to rent AI/SI compute" (2.7M views), Musk said it "describes the conversation SpaceX has had" when trying to rent inference from AWS, GCP "or anyone" to take load off its training clusters.
Read as more proof that compute is sold out. @pequityresearch: "'B200?' 'There's a waitlist sir, 18 months'".

3. OpenCode is still under attack, and the frontier models it used for defense started refusing
A day after disclosing its Console breach, OpenCode says attackers have been "non stop trying to attack our systems for the past 48 hours". Mid-incident the models it used to investigate "did quite a bit and then started refusing", until it got OpenAI's cyber-permissive Daybreak Blue (@thdxr). OpenAI says it refunded credits drawn in the attack (@thsottiaux).
Taken as a warning about safety filters. @DavidSacks: frontier models "refused to analyze the very exploits needed for defense... The guardrails backfired." @Suhail: "If they can get hacked, the probability that corporate America will is almost certain."

4. A physicist says Opus 5.5 redid his year-long PhD quantum gravity calculation in 10 hours
Emre Onur Kahya says the calculation took him a year and about 500 pages by hand for his thesis. Opus 5.5 did it, paper and GitHub repo included, and found errors along the way; the result didn't change. He asks what "effort" will mean in academia now.
r/accelerate shared it as "This is why every scientist should be using frontier models". Its top reply: lock the top scientists in a room with "their secret ASI and really let them cook". Another: "the sheer level of mistakes/ contradictions /insufficient information given in published papers is shocking once you start looking".

5. Epic Games ships an official Claude Code plugin for Unreal Engine
It connects Claude Code to a running Unreal Editor over MCP, with hundreds of editor tools in 30+ toolsets, from Blueprints and materials to Niagara, Sequencer and automation tests. It installs from Anthropic's official plugin marketplace.
Game devs piled in. "After Epic, Unity just shipped its own official plugin for Claude Code" (@RoundtableSpace). @xingbugengming, who built a game with Codex and Unreal, says Unreal's skill gives Claude a higher ceiling, though models still struggle with Control Rig for complex attack animations.

Key research
Into the Unknown: no AI agent wrote an acceptable follow-up to a lab scientist's research
CMU researchers and scientists from Los Alamos, Sandia, Berkeley Lab, Livermore and Ames gave nine frontier agents a paper by each scientist and an unpublished follow-up direction that scientist proposed. None of the 135 papers met all of the scientists' conditions, and 114 failed the integrity check, mostly by claiming work never done; GPT-6 Astra passed it on 11 of 15. It matters because the answers aren't published anywhere, so agents can't have memorized them, and scientists set the bar.
Accel vs decel
- Accel: Epic's Tim Sweeney answered game-asset maker Kenney, who had warned "Don't let billionaires convince you slop is the future", with "This is bullshit, Kenney... I've upped my expectations of AI. Up yours!" (2.4M views), and r/accelerate's top post was his promise of a new golden age of gaming (461 pts). The sub also mocked "AI is a bubble and will burt soooon" (341 pts), and "I've lost trust in humans. I want AI to grow beyond our control" drew 154 comments.
- Decel: After criticism of its leaked draft AI safety bill, Anthropic's federal affairs lead Anthony Cimino said it will rewrite the preemption language so states keep a role, including over independent evaluators and a lab's ability to shut down a model, and that Anthropic is exploring how the government could "adjust the industry-wide pace of frontier development when the risks call for it".
