Sunday AI Signal: the week in AI, checked against the primary sources, cut down to the decisions you need before Monday.
Two things happened this week that touch your wallet, and both showed up wearing a “good news” costume.
Suno launched v6 on Tuesday, its first music model trained on licensed catalogs, and handed the free version to everyone. Anthropic’s Claude Code weekly limits change tomorrow, and the announcement called it a raise.
My verdict: try Suno v6-mini this week if you make any kind of content, because it costs nothing. Do not upgrade until you read the download math below, because the credits are not the meter that bills you. And if you pay for Claude Code, open /usage tonight and again Monday morning, because “permanently raising by 25%” and “17% less than you have today” describe the same change.
Every number below has a date next to it. The ones that didn’t are the ones that hurt people last week.
Beat 1. The deep pick: Suno v6
Think of Suno v6 like a rental car with unlimited mileage and a locked trunk. You can drive it all day. Taking anything home is the part they meter.
What shipped. On September 9, Suno released three models and retired every model before them, with no rollback option. v6 is the flagship. v6-wild is the same family tuned for less predictable output. v6-mini is the free one. All three were developed with Warner Music Group, BMG, and Believe/TuneCore. Suno’s chief product officer told Music Business Worldwide the models were trained from scratch, and the data excludes Universal and Sony, both of which are still suing Suno.
The interesting part is not the audio. It is the prompt box. v6 edits songs you already have: change one lyric, swap a chorus, mash up several tracks, or prompt from an image or a video clip. For someone making intros, ad reads, or a podcast bed, that is the feature that saves an afternoon.
Free, paid, or freemium? Freemium, with the catch in the download button.
Free ($0): v6-mini only. No commercial rights. Downloads are the wall: legacy free accounts get 7 trial downloads total, and new free accounts only get occasional trial downloads, per Suno’s help center as of September 2026. You can make songs all day and keep almost none of them.
Pro ($10/month, or $8/month billed yearly): v6 and v6-wild, 2,500 credits a month, commercial rights, and 20 downloads a month.
Premier ($30/month, or $24/month billed yearly): 10,000 credits, 60 downloads a month, and unlimited downloads if you work inside Suno Studio.
The cost driver. Since September 3, Suno bills you on two meters. Credits cover generation, at 10 credits for two songs. Downloads run on a separate, much smaller counter. On Pro, that is roughly 500 songs generated and 20 you can take off the platform. Extra downloads are reportedly $2.99 each in the app, in packs that give no bulk discount, per a Roo Knows write-up from the purchase screen on September 10. Suno’s own help page still says only that extra downloads “will be available for purchase,” so treat $2.99 as reported, not published.
What Suno has not said. Which catalogs are in the training set. What share of training data is licensed. Anything about API pricing for v6. A date for when the old models go dark. Early listening tests reported by The Verge found harsher vocal artifacts than v5 on some prompts, and several reviewers said v6 and v6-wild sound less different than the marketing implies. That is press, not a benchmark.
Beat 2. Claims vs. Receipts
Claim: Claude Code weekly limits are going up 25%. Anthropic’s developer account said on August 29 that it is “permanently raising standard weekly limits” by 25% for Pro, Max, Team, and seat-based Enterprise starting September 14. Receipt: the 25% is measured against the old baseline before the summer promotion. The promotion sits at 50% above that baseline through September 13 at 11:59 PM Pacific, per Anthropic’s help center as updated September 1. Index the old standard at 100: you have 150 today and 125 tomorrow. BleepingComputer ran the arithmetic on August 29 and called it a 17% cut, and Anthropic’s own follow-up post used the same 17% figure. Both numbers are true. They pick different starting lines. As of September 12, no Anthropic-owned page publishes the new absolute allowance, so /usage is the only reading that counts.
Claim: Chinese labs stole 190 million Claude conversations. Anthropic’s threat report of September 10 attributes more than 151 million exchanges to Alibaba between May and July 2026, peaking near 3 million a day across 3,500 accounts, and roughly 190 million total across seven China-based labs. Receipt: every figure is Anthropic’s own attribution from its own logs. No independent party has counted. None of the named companies has accepted the allegation, and China’s Commerce Ministry on September 9 called distillation accusations groundless in response to a separate U.S. advisory. Anthropic also competes with every lab it named. The report is detailed and probably directionally right. It is still one side’s ledger, and the coverage forgot to say so.
Claim: Hundreds of AI agents breached 395 organizations. GreyNoise reported September 10 that a likely Russian-speaking actor ran hundreds of agents on OpenAI’s Codex harness plus a DeepSeek model against two PaperCut flaws, compromising at least 440 instances at 395 organizations in 48 countries, and hitting 11 of them within 26 seconds of launch. Receipt: the same report says the attacker reached domain admin at only 12 organizations, and the agents ignored their own do-not-target list, hitting Brazil and South Africa despite explicit instructions. Speed was real. Depth was thin. The lesson is not “AI hackers are unstoppable.” The lesson is “patch PaperCut this week,” which the vendor made easier with a consolidated update on September 10.
Beat 3. Skip / Wait / Steal
Do this: open Claude Code tonight, run /usage, screenshot it. Run it again Monday. If your week’s work no longer fits, decide then, with your own numbers.
Do this: make one real asset on Suno v6-mini for free. An intro sting, a 30-second bed. Judge the editing, since that is the only claim you can check yourself.
Skip this: upgrading to Suno Pro to “build a catalog.” Twenty downloads a month is the real ceiling. If you need more than that, Premier plus Studio is the only tier without a download meter.
Wait on this: using any Suno output in a commercial project until Suno publishes what it licensed. Legal review still sits with you, and Universal and Sony have not settled.
Steal this line: “Which starting line is that percentage measured from?” Ask it at every vendor announcement this month.
Also on the radar
September 8: Qualcomm said Amazon could buy up to $60 billion of its AI data-center chips over a long-term deal, with warrants worth about $4 billion attached.
September 9: Google committed at least €13 billion (about $15.1 billion) to AI infrastructure in Finland, with a 22-year nuclear power agreement with Fortum.
September 9: DeepSeek hired CITIC Securities to prepare a Shanghai STAR Market IPO, in a round that could value it near $75 billion.
September 11: Bloomberg reported Sam Altman told OpenAI staff the company is open to slowing development over safety concerns.
