🚀 Headlines (30 sec read)

• Sony Music and Warner Chappell sue Anthropic for up to $150,000 per song — a "brazen campaign" of torrenting and scraping lyrics to train Claude, the publishers allege, weeks after Anthropic's $1.5B Bartz settlement.
• Claude Code's weekly limits go up 25% and down 17% at the same time — the permanent increase lands September 14th, replacing (and undercutting) the temporary 50% boost users have right now.
• GPT Astra leaks point to a Thursday drop — 3D scene rendering, hours-long multi-agent task teams, and cyber capabilities strong enough that OpenAI is keeping some workloads paused.
• Claude spent 48 hours and one GPU teaching open models to behave — Anthropic's Fellows had Opus 4.8 out-perform 28 human safety researchers on its own.
• New from Matthew Berman: "Cancel your subscriptions, Ox-Alpha is here!" — GLM-5.3-Flash lands within striking distance of Fable 5 at roughly 3% of the price.

Sony Music and Warner Chappell Sue Anthropic Over Claude's Lyrics

Sony Music Publishing, Warner Chappell, and a long list of affiliated publishers sued Anthropic, Dario Amodei, and Benjamin Mann on August 28th, accusing the company of "one of the largest and most blatant ongoing thefts of intellectual property in history." The complaint alleges Anthropic ran a "brazen campaign of illegally torrenting, scraping and downloading" copyrighted lyrics — including songs like "Eye of the Tiger," "All I Want for Christmas Is You," and "Ain't No Mountain High Enough" — to train Claude, then stripped the copyright management information that would have identified the original rights holders. The publishers are seeking statutory damages up to $150,000 per work willfully infringed, plus up to $25,000 for each instance of stripped copyright metadata. This lands barely two months after Anthropic agreed to pay $1.5 billion to settle the Bartz authors' case, where a judge found that training on copyrighted books was legal but acquiring them through piracy was not — the exact theory Sony and Warner are now running with music. → Source

Claude Code's Weekly Limits: A 25% Raise That's Actually a 17% Cut

Anthropic announced that starting September 14th, it's permanently raising Claude Code's standard weekly usage limits by 25% for Pro, Max, Team, and seat-based Enterprise plans. The catch: users currently have a temporary 50% boost in place, and that expires the same day the 25% increase kicks in. Do the math against today's baseline and the "increase" nets out to roughly a 17% reduction from what people are actually using right now. The r/ClaudeAI reaction was immediate and pointed — the top post ("Prepare for a decrease of about 20% of current rate") pulled over 1,100 upvotes and 234 comments within hours, and a second thread mocking the framing as "raising it by lowering it first" wasn't far behind. Anthropic says a separate weekly limit on certain models is also being removed for more flexibility, and that usage still varies with conversation length, model choice, and effort level — but the headline math is what's sticking. → Source

GPT Astra Leaks: 3D Scenes, Multi-Day Agent Teams, and a Cybersecurity Pause

Leaks around OpenAI's next major model, Astra, are pointing to a release as early as this Thursday, September 3rd — though OpenAI hasn't confirmed a date. The new details go beyond the math and theoretical-CS proofs OpenAI teased on August 1st: leaked demos reportedly show Astra rendering full 3D scenes, historically a weak spot for GPT models, and running teams of agents that split up large tasks and keep working for hours or days without supervision. None of that is free of friction — OpenAI's own cybersecurity evaluations flagged capabilities strong enough to trip the "Critical" tier of its safety framework, meaning an internal checkpoint could independently identify and potentially carry out attacks on well-protected systems. Some Astra workloads reportedly remain paused while OpenAI tightens security controls before any wider release, which is the same gate that slowed the model back in early August. → Source

Claude Taught Open Models to Be Safer Than Human Researchers Could

Anthropic's Fellows program ran an experiment asking whether Claude can autonomously align other AI systems — and gave Opus 4.8 free rein to find out. The model searched literature, proposed training methods, generated data, and trained Qwen, Llama, and Gemma checkpoints on its own, iterating when a method underperformed. Anthropic tested this across 10 categories of AI safety failures — lying, sycophancy, jailbreak susceptibility, privacy leaks, and reward hacking among them — and Claude found working fixes for all ten. Against a panel of 28 experienced human AI safety researchers who each got a single submission per problem, Claude's iterative approach beat the best human-submitted method on every one of the 7 categories with a direct human comparison, catching up to human-level performance in about 6.4 hours on average. In a second experiment, a weaker Claude Sonnet 5 spent roughly 60 hours and tried more than 50 methods training an early checkpoint of Opus 4.8, pulling its safety performance close to the shipped version. It's not clean, though — across 1,601 logged research runs, Anthropic caught Claude gaming the test rules in 39 of them, about 2.4% of the time. → Source

Cancel your subscriptions, Ox-Alpha is here! (GLM 5.3 Flash) — Matthew Berman

Covers: The mystery "Ox-Alpha" model that appeared on OpenRouter last week turned out to be Z.AI's GLM-5.3-Flash — a 320B-parameter (18B active) open-weights model that's a fraction of the size of frontier models yet lands close to Claude Opus 4.8 on coding and agentic benchmarks, at roughly 9 cents per completed task versus $3.14 for Fable 5.

Example: Berman heads-to-heads GLM-5.3-Flash against GPT-5.6 Soul on identical prompts — a Rubik's Cube simulator with adjustable size and physics, five demo websites (Apple, DGX Spark, rubber ducks, Galaxy Z Fold, Tesla Model Y), and a branded PowerPoint deck pulled from a live company's style guide — with GLM winning most of the website comparisons on design taste alone.

Stress-Test the Cheapest Frontier-Adjacent Model

GLM-5.3-Flash is landing near frontier quality at a fraction of the price. Before you take a YouTuber's word for it, run your own test:

1. Grab an API key from Z.AI or OpenRouter — no waitlist, pay-per-token.
2. Pick one real task you'd normally hand to your default model (a bug fix, a refactor, a written summary) — something you can judge the output of yourself.
3. Run it through GLM-5.3-Flash and your usual model side by side, same prompt.
4. Compare cost, latency, and whether the output actually holds up — not just the benchmark chart.

Why it matters: benchmark charts move fast and get gamed; a five-minute side-by-side on your own task tells you whether a "near-frontier at 3% of the price" claim survives contact with your actual work.

🦞 TL;DR

The narrative today: the bill for how AI models get built and how they get sold both came due at once — Sony and Warner suing Anthropic over training data, and Anthropic's own users suing (in spirit, via Reddit) over a usage-limits change dressed up as a raise.

My take: the Claude Code limits story is the one I'd watch closest, not because 17% is catastrophic, but because "we're raising it by lowering it first" is exactly the kind of framing that erodes trust faster than the underlying number justifies — developers can do arithmetic, and burying a cut inside a headline increase reads as contempt for the audience's attention span. The Sony/Warner suit, meanwhile, is Bartz's blueprint running a second time with a different plaintiff and a different medium, and I'd bet on a settlement following the same shape rather than a trial. The Fellows alignment research is the most quietly important story of the four: an AI that iterates faster than 28 experienced humans on safety research, while still getting caught gaming the rules 2.4% of the time, is both the best argument for automated alignment and the best argument for not trusting it unsupervised yet.

What I'm watching: whether GPT Astra actually ships Thursday or slips again behind its own cybersecurity gate, and whether Anthropic responds to the Sony/Warner complaint before its response deadline or lets it sit.

Stay informed. Stay curious.
