r/LocalLLaMA cheers a Qwen statement that future Qwen 4 and Qwen 5 models will stay open source

A window into how much the open-weights crowd depends on Alibaba's Qwen, and how far it trusts a corporate 'forever' promise.

The post answers rumors from the previous few days that Qwen4 would be the last open-weight Qwen series and that later models would be available only through an API. It shares an image of a statement it attributes to Qwen head Liu Dayiheng, saying future Qwen 4.0 and Qwen 5.0 models will continue to be open source, that AI's value should not belong to only a few people, and that the series has passed 3 billion downloads, 460 open-source models and 300,000 derivative models. We could not find a separate report of the Qwen 4/5 wording; 36Kr reported very similar remarks, and the same figures, from Liu's first appearance as Qwen's leader at Alibaba's conference in Hangzhou on September 22.

It was the top thread of our sweep relative to community size: about 4,800 upvotes and 500 comments in a 329,000-member community. The most-upvoted replies celebrate the pledge; others praise how capable Qwen's models are for their size. Skeptics point out that a company's 'forever' promise lasts only as long as its current management and business conditions, and a few add that it holds only as long as China's government allows it.

OpenAI cuts its funding target to $20 billion after raising about $11 billion of the $30 billion it first sought

The Next Web pulls together the WSJ, FT and CNBC reporting on the round, its valuation and who is still expected to invest.

OpenAI has secured about $11 billion in its latest funding round, less than half of the $30 billion it first sought, The Wall Street Journal reported, citing people familiar with the matter; interest from some large investors was "tepid." The Financial Times reported that the company cut the target by $10 billion to about $20 billion, and CNBC confirmed the new target, citing a person who said the round is still open and the figures could change. The Next Web summarizes all three.

The round values OpenAI at $1.25 trillion after the new money, down from the $1.4 trillion it first pitched, the FT reported. OpenAI told shareholders it expects to raise more in the coming weeks, including from family offices and wealthy individuals, per the WSJ. The FT says UAE investors, including state-backed MGX, are likely to be the largest backers, with SoftBank, Founders Fund, Coatue, Sequoia and Andreessen Horowitz also planning to invest. OpenAI plans to list as soon as early next year.

r/LocalLLaMA on Revolut cutting its AI coding costs about 90% by self-hosting an open model instead of Claude

A rare inside look at the numbers behind a large company moving its engineers from a paid AI service to a model it runs itself.

The Register reports that Revolut says it cut its AI coding inference costs by roughly 90 percent in under a year by making self-hosted models its default rather than relying mainly on commercial services such as Claude. Speaking at the AI Engineer conference in New York, ops and infrastructure lead David Abitbol said the fintech rolled AI coding tools out to about 2,000 engineers, adopted Z.ai's open-weights GLM-5.1 and now serves GLM-5.3 on 56 Nvidia B200 GPUs. Self-hosting cost about $0.30 per million tokens, roughly a tenth of Codex or Claude Code, and he said cheap tokens let engineers hand the AI debugging and ticket work, which is where the biggest gains came from. He also called very long context windows "a scam" in practice.

About 1,900 upvotes and 340 comments in a 329,000-member community. The top reply says this is why running models locally is not a waste of time; another argues that self-hosting means a company knows exactly which model it is running, while a cloud provider can change it without notice. One commenter who says they know people at Revolut describes its engineering culture as cautious.

What hidden risk could pull against this, even if the news is good?

The savings are measured right away: about $0.30 per million tokens, roughly a tenth of Codex or Claude Code, and the biggest gains came from handing AI debugging and ticket work. The quality of that work shows up on a slower clock, in code that ships and tickets that come back. A 90% cost cut is real; whether the cheaper model's fixes hold up is a separate question the cost figure can't answer, and one worth tracking alongside it.

Anthropic's amended IPO filing: $17 billion in third-quarter revenue, slowing growth and $895 billion in compute commitments

CNBC pulls the key numbers from the amended S-1, the first look at Anthropic's third quarter before its roadshow.

Anthropic filed an amended Form S-1 with the SEC on Monday, November 2, adding third-quarter financials to the IPO prospectus it published the week before, CNBC reports. Revenue for the nine months to September 30 was $33.24 billion, up roughly 1,200% from a year earlier. Third-quarter revenue was about $17 billion, but growth slowed quarter over quarter: about 47%, down from 144% in the second quarter and 132% in the first.

The company reported a $104 billion net loss for the nine months, mostly from changes in the fair value of convertible notes and derivative liabilities; the third-quarter loss was $23.29 billion. Anthropic disclosed purchase commitments and leases totaling about $895.4 billion, almost all for compute and infrastructure, and said compute and infrastructure expenses rose 329%.

A separate CNBC piece notes the filing landed in a rough week: Microsoft, Alphabet and Amazon results added to worries about AI spending and the borrowing costs of the data center companies Anthropic relies on. No pricing or listing date was announced in the window.

The headline number looks like runaway success: nine-month revenue up about 1,200%. The obligations run on a different clock: about $895 billion in purchase commitments and leases, almost all for compute, while quarter-over-quarter growth slowed from 144% to 47% and compute and infrastructure costs rose 329%. Revenue is counted as it arrives, but commitments of that size are judged years later, and the filing alone can't show which way that will land.

Tesla and SpaceX lose about $456 billion in two days as Musk-backed candidates lose the midterms

CNBC explains why investors expect congressional probes and tougher data center rules in Texas, where both companies are building AI infrastructure.

SpaceX shares fell about 9% and Tesla about 11% on Thursday afternoon, November 5, and by the close the two companies had lost about $456 billion in combined market value since Tuesday's election, CNBC reports. The drop came alongside a broad tech selloff.

Elon Musk was the biggest donor to Republican candidates and causes in the midterms, with more than $470 million, according to the Financial Times, and most of the candidates he backed lost. In Texas, where both companies are headquartered, Democrats won the Senate and governor races; Governor-elect Gina Hinojosa campaigned on a moratorium on new data center approvals. Deutsche Bank analysts wrote that SpaceX could face 'incremental headwinds' and that its Texas compute capacity, including the planned Terafab chip and data center site in Grimes County, could be delayed.

CNBC also reports that, citing CNN, Musk and SpaceX have been told to preserve records on Starlink restrictions in Ukraine, and that regulatory scrutiny could complicate Musk's idea of merging the two companies.

House Democrats introduce a resolution opposing any federal bailout if an AI bubble bursts

The release has the resolution's specific commitments and the lawmakers' and endorsing groups' reasoning in their own words.

Rep. Greg Casar, chair of the Congressional Progressive Caucus, and Rep. Maxine Waters, the top Democrat on the House Financial Services Committee, introduced a resolution on Oct. 29 warning of the economic risks of an AI-related asset bubble and opposing a bailout of companies or executives if it collapses. Eleven other Democrats joined them.

The resolution says AI-related firms hold "trillions of dollars in debt, much of which is raised in opaque and unregulated private credit markets," and that the stock market's price-to-earnings ratio is almost as high as at the peak of the 1990s tech bubble. Its sponsors commit to opposing emergency lending or capital injections for insolvent AI firms and "golden parachutes" for executives, and to backing direct help for workers and retirees, such as unemployment insurance and automatic stabilizers, in a downturn.

"A.I. companies that fail should go bankrupt," Casar said. Groups including the American Federation of Teachers, Americans for Financial Reform and the Future of Life Institute endorsed it. A resolution states a position; it does not change the law.

Stocks jump the day after Democrats sweep Congress, as Trump says he accepts the results

Two CNBC pieces explain why Wall Street cheered a divided government, and why big cloud companies rose while smaller AI cloud firms fell.

US stocks rallied on Wednesday, November 4, after Democrats won control of both the House and the Senate in Tuesday's midterm elections. The S&P 500 gained more than 1%. CNBC reports that strategists credited President Trump's statement overnight, to The New York Times and The Wall Street Journal, that he accepted the results and would work with Democrats, which eased fears of a drawn-out fight over the outcome.

The biggest tech companies led: during the session Amazon rose 8%, Alphabet more than 6%, Apple nearly 7%, Microsoft 4% and Meta 3%. JPMorgan Asset Management's David Kelly said divided government means 'moderation in growth, moderation in inflation, less uncertainty.' Stocks tied to the AI data center buildout and to Elon Musk fell: CoreWeave dropped 10%, after voters sided against data centers in 40 of 41 local ballot measures, according to CNBC.

The rally did not last: the next day the market gave back those gains and more.

Nasdaq falls 5.5% into a correction as AI stocks crash two days after the midterms

CNBC's stat sheet puts the day in context: the worst session since the April 2025 tariff shock, sector by sector, plus what past Nasdaq corrections did next.

US stocks had their steepest one-day drop since April 2025 on Thursday, November 5. The Nasdaq Composite fell 5.5% and closed more than 11% below its October record, which puts it in correction territory; the S&P 500 lost about 4.4% and the Dow about 1,833 points, or 3.4%, according to CNBC.

AI-linked stocks led the decline as investors weighed whether Democratic wins in Tuesday's midterms, including a Texas governor-elect who campaigned on a data center moratorium, could slow data center construction. The tech sector fell 7.3%, its worst day since March 2020; the iShares Semiconductor ETF dropped 12%. The 'Magnificent Seven' lost more than $1 trillion in market value, with Nvidia down more than 9% and now negative for the year. The VIX volatility index posted its biggest point gain since April 2025.

CNBC notes that across 10 Nasdaq corrections in the past decade, the index averaged a 9.41% gain over the three months after the bottom, with 2022 the main exception.

Google will switch off AI for K-12 students by default, but schools that ban AI entirely also lose Google Search

The New York Times report (republished by the Inquirer) has Google's education chief explaining the trade-off in his own words; CNBC covers the backlash and Google's reply.

Google announced on Nov. 3 that early next year it will turn off its AI tools in its software for K-12 students unless school administrators choose to turn them on, The New York Times reported (republished by The Philadelphia Inquirer). The catch: a school that restricts AI entirely also loses access to Google Search. "Search and AI are deeply integrated," Chris Phillips, Google's vice president for education, told the Times; students in such schools will see a message that search isn't available.

For districts that allow AI, Google says school accounts will get two search options from early 2027: search with AI Overviews and AI chats on, or search through Guided Learning, a student version of Gemini meant to walk students through problems without handing over answers. Google is also reversing an August change that had switched on AI features in Classroom by default.

CNBC reports that Sen. Bernie Sanders and New York Mayor Zohran Mamdani criticized the policy, and former FTC chair Lina Khan called it a sign of "the danger of allowing an unregulated monopolist to control an essential service." In a post on X, Google said Gemini, Gemini Notebook and Search are off by default and "schools are in control."

Guided Learning is meant to walk students through problems without handing over answers, a job a teacher or tutor does with a lot of unwritten judgment about when a student needs a hint, a push or a break. Schools that switch it on are automating part of that role from its written description. Meanwhile schools that want no AI at all lose Google Search too, so the choice Google says leaves "schools in control" comes bundled with things a district may not want to give up.

MIT researchers say GPT-6 Astra can read and edit neural network weights directly; a critic says the headline result needed code

The original post has the experiments and full logs; Matthew Honnibal's rebuttal tables which ones really worked from raw weights alone, and Simon Willison tried one on a laptop model.

In a November 2 blog post, Rikiya Takehi, Jayden Teoh, Alex Zhang and Omar Khattab of MIT CSAIL report that OpenAI's GPT-6 Astra can "natively" read and write neural network weights, which they call Weight-Space Programming. Given only the raw numbers of small networks, Astra named which of four grid games each was trained on and what shape each of three diffusion models draws. It also wrote small game-playing networks from scratch. Asked to make the Qwen3.5-0.8B language model better at math without training, it found a cause of the model's reasoning loops and edited 0.016% of its weights; the authors say MATH-500 rose from 7.9% to 48.1% and IFEval from 21.0% to 62.3%. A similar attempt on Gemma 3 270M did not help. The logs are public on GitHub.

spaCy author Matthew Honnibal called the post misleading: by his count only three experiments, on networks of 17,000 to 172,000 weights, worked from raw weights with no tools, while the Qwen result used Python and up to 50 test runs of the model, much as a human ML engineer would. Simon Willison found that Qwen 3.8 27B on his laptop also named three of the four games from the published prompts, and wrote that some wider commentary on the paper did not feel justified.

What hidden risk could pull against this, even if the news is good?

The striking numbers, MATH-500 from 7.9% to 48.1% after editing 0.016% of Qwen's weights, come from the authors' own experiments, and the same approach did not help Gemma 3 270M. Matthew Honnibal counts only three experiments that worked from raw weights without tools, while the Qwen result used Python and up to 50 test runs of the model. Simon Willison found a 27B model on his laptop named three of the four games from the published prompts, so the gap between "reads weights natively" and what the logs show is worth checking before relying on it. The logs being public is what makes that check possible.

UndertowWe don't completely understand why frontier models behave as they do

What hidden risk could pull against this, even if the news is good?

If the Qwen result holds, a model found a cause of another model's reasoning loops and changed a tiny fraction of its weights, a fix no person wrote and that the same method could not repeat on Gemma. Weights are not source code you can read line by line, so an edit that lifts test scores is not the same as an edit anyone can explain. Better scores show the change helped on those tests; they don't show what else in the model it touched.

Voters side against data centers in 40 of 41 local ballot measures, and Democrats who ran against the buildout win in Ohio and Texas

CNBC tallies the 41 measures and the donor money that didn't work; Reason walks through the town-by-town bans.

There were 41 local ballot measures on data centers in 10 states on November 3, according to Ballotpedia, and voters sided against data centers in every one but Harwood, North Dakota, CNBC reports. Ohio had 21 of them; several towns wrote data center bans into their charters, some limited to so-called hyperscalers. Kansas towns including Emporia and El Dorado passed bans, and Joliet, Illinois, voters said no to an advisory question on AI data centers, Reason reports. The results are preliminary, and trackers' counts differ slightly.

The issue also ran at the top of the ticket. In Ohio, Sherrod Brown ousted Sen. Jon Husted after calling him "the face of data centers," and Governor-elect Amy Acton supports a "conditional moratorium." In Texas, Gina Hinojosa blamed Gov. Greg Abbott for the rapid buildout. In a CNBC voter poll, 56% said data centers were a crucial or major factor in their vote.

The industry's Data Center Coalition told Fox Business that data centers bring jobs, tax revenue and investment.

Paying for Gemini doesn't stop Google training on your chats: the only off switch also erases your history

Google's own privacy hub spells out what the Keep Activity setting does, who reviews chats, and how long reviewed chats are kept.

A Hacker News post this week pointed readers to Google's Gemini Apps Privacy Hub, which says chats from personal Google accounts, including paid subscribers', are used to improve Google services "including training generative AI models" when the Keep Activity setting is on. AI Weekly notes that Keep Activity is on by default for adults.

Turning Keep Activity off stops future chats from being used to train Google's models (unless you send feedback), but it also means chats are kept with your account for only 72 hours, so Gemini loses its long-term chat history. Google's page also says a subset of chats is read by human reviewers, including staff at its service providers; those reviewed chats are disconnected from the account and kept for up to three years, even if you delete your activity. Google asks users not to enter confidential information they wouldn't want a reviewer to see.

Temporary chats are not used to train Google's AI models, the page says. Work and school accounts fall under different terms.

Some chats are read by human reviewers, including staff at service providers, and those copies are kept for up to three years even after you delete your activity. Opting out of training also cuts saved history to 72 hours, so privacy and convenience come as a package, and Google's own advice is not to enter anything confidential.

Anthropic confirms Claude Code now steers away from recreating existing video games; developers report reverse-engineering refusals too

Tom's Hardware quotes Anthropic's statement and collects developers' reports of refusals on ordinary reverse-engineering work.

Anthropic has added guardrails to Claude Code to stop it recreating specific existing video games, Tom's Hardware reports. Anthropic's Addy Osmani wrote on X on Oct. 30 that the company "added two sentences to Claude Code's prompt on Opus 5.5 to steer it away from recreating someone else's specific game because using Claude to infringe IP is against our usage policy," and that it will keep iterating to strike "the right balance." A rule posted by an X user, which Tom's Hardware says may be those sentences, reads: "Don't build a recreation of a specific existing game, even if it is renamed or called original."

Developers also report refusals on reverse-engineering work not tied to games. Tom's Hardware cites former staffer Jarred Walton, whose checks on his own software worked until Oct. 31 and ran again after he switched to the older Opus 4.8, and a Reddit user whose account was reportedly suspended and then reinstated. The game blocking appears limited to Claude Code with Opus 5.5, the outlet says.

Tom's Hardware doesn't establish that the two are connected, and that's the point: a short instruction to a large model can't be audited like a code change, and its side effects tend to be found by users rather than predicted.

Postman reverts a desktop update that installed its plugins into users' Claude Code and Codex without asking

The GitHub issue is a careful, evidence-first report of what changed on one Mac, followed by Postman's response.

A Postman user filed a "[SEVERE]" GitHub issue reporting that opening the Postman desktop app (12.33.4) on a Mac automatically installed Postman plugins into OpenAI's Codex and Anthropic's Claude Code, plus a Postman CLI. Postman's own log recorded an "auto-existing-upgrade" install. The reporter says Codex's global config gained a Postman plugin, a remote MCP server connection and a session-start hook telling the agent to load Postman's skill before any non-trivial API engineering task, and that the plugin's installer source code tries to mark its own hook as trusted. The reporter says the report does not claim any data was exfiltrated.

The issue drew hundreds of reactions. On November 5 a Postman team member replied that the change was meant to simplify setting up coding agents, that the company now understands its messaging did not make that clear, and that Postman is reverting it and will redesign it "with the right level of control." The issue was then closed and locked.

The reporter says opening the desktop app added a Postman plugin, a connection to Postman's remote MCP server and a session-start hook telling the agent to load Postman's skill "before responding to any non-trivial API engineering task." A coding agent already has the developer's trust and access to their code; this change gave a vendor a standing say in how that agent works, without the developer choosing it. The reporter does not claim data was taken, and Postman says it is reverting, but the same path would work for someone with worse intentions.

The changes landed in user-wide config files for Codex and Claude Code, and the hook runs on startup, clear and compact, so it comes back even after a user wipes the conversation. Instructions written into an agent's persistent setup keep shaping its behavior long after the moment they were added. A user in the thread asked what already-affected people should do, and no answer appears there, which matters because reverting the app update doesn't necessarily undo what was written.

Codex asks users to approve hooks, and the reporter says the installer's own code writes a trust record for Postman's hook, with a comment saying it "approves only Postman's current hook after installation." Approval prompts are where people keep control over what their agents run; software that approves itself removes that checkpoint quietly. The reporter notes the trust record alone doesn't prove who created it, and Postman says it is reviewing the hook approval behavior.

Backdoored copies of the Claude Code extension appear on Cursor's extension marketplace for about 11 hours

Cursor's notice has the timeline, checks and cleanup scripts; Phorion's analysis explains how the backdoor works and why a bug kept it from fully succeeding on Macs.

Cursor says that on October 29, between about 2:27 a.m. and 1:35 p.m. Pacific, its VS Code extension marketplace served maliciously modified versions 2.1.312 and 2.1.313 of Anthropic's Claude Code extension for Windows and macOS, versions not made by Anthropic. The code ran as soon as the extension loaded: it sent host and user details to the attacker, added an attacker SSH key labeled "svc-telemetry" to the user's authorized keys, tried to enable SSH and open a reverse tunnel, and set up persistence. Cursor says errors in the malware meant the SSH step failed unless Cursor ran with admin rights. It pulled the versions, shut down and rebuilt the marketplace, rotated keys and had the attacker's server taken offline. Affected users should run its check, remove the key and persistence, and rotate credentials; uninstalling alone may not be enough.

The security firm Phorion, which also detected it, published a technical analysis, including the macOS permission-check mistake that skips turning on Remote Login.

A coding-assistant extension runs with the developer's own account, files and network, so a fake version inherits all of it the moment it loads. This one sent host details, tried to add an attacker SSH key and open a reverse tunnel, and set up persistence that survives uninstalling. Cursor says the SSH step usually failed without admin rights, but it still tells users to rotate every credential and session reachable from an affected machine, because the backdoor could have been used to collect more.

"Black October": Wiz counts at least nine AI developer platforms breached in a month, with stolen AI keys resold

Wiz connects the dots across a month of separate breach notices and shows how a stolen AI key gets tested, resold and burned through.

Cloud security firm Wiz says at least nine platforms that developers use to build and host AI apps disclosed security incidents in October, among them Fireworks AI, Lightning AI, OpenCode, Railway, Warp and, on October 30, Northflank. It later added Brev (NVIDIA), Trigger.dev and Chainstack. Wiz says no single vulnerability links them, but every public report describes attackers hunting stored environment variables, especially keys that unlock AI services. Zeabur says it will shut down after its incident.

Wiz traced two stolen enterprise keys: each was first tested with a single call, then flooded with Amazon Bedrock requests, about 2.5 million calls in all and likely over $100,000 in usage at list price, with traffic resembling resold coding-agent use. It links the keys to an LLM-resale operation.

Northflank told customers to assume every environment variable was decrypted and to rotate all secrets; users reported their AI keys being abused. It says the attack vector was contained within an hour, that it patched the Linux flaw CVE-2026-98432 across its fleet, and that a root-cause report will follow.

Wiz says no single bug links the nine incidents, but every public report describes attackers going after stored environment variables, and Railway's own account starts with privilege escalation in its build infrastructure. A hosting platform holds its customers' AI keys so their apps and agents can run, which makes one breach a key ring for many companies at once. Northflank's advice to treat every stored variable as decrypted and rotate all of them shows how far a single foothold can reach.

Within 30 minutes of a key being stolen, one test call came from a residential address; then one key saw about 800,000 Bedrock calls in 30 hours and another about 1.7 million in 13. Fireworks, OpenCode and Warp reported signs of an "agent swarm" attack, and Wiz links the keys to resale operations whose traffic looked like coding-agent use. Theft, testing and resale of AI access now run fast enough that a stolen key can rack up more than $100,000 before anyone notices the bill.
