Two judges to one, the D.C. Circuit backed the Department of War's exclusion of Claude, imposed after Anthropic refused to relax limits on lethal autonomous warfare and domestic surveillance. The dissent reads that law as aimed at covert subversion.
One session in a Muse VM's logs skipped Meta's Avocado model. A subagent ran on azure/muse-special, and its call IDs and signatures look like OpenAI's, per the user who dug through the files.
Plugin and MCP Connector builders get their own door into Claude Directory, a new submission flow, and according to Claude's website, plugin usage stats come with it.
Somebody hammering Claude with distillation prompts and hitting the safeguards will pay for every blocked request again, Anthropic says, though only in three categories with low false positive rates.
Close your laptop and a Claude Code session started with claude --cloud keeps running on an Anthropic-managed VM. There's no separate compute charge for it, but it draws on the same rate limits as all your other Claude usage.
"The Anthropic knot" is how a Trump political adviser's memo, obtained by Axios, labels Dario and Daniela Amodei's ties to effective altruism. It's circulating as Anthropic prepares for what's expected to be a record-setting IPO.
The heads of OpenAI and Anthropic took turns at the UN Security Council to ask for international coordination on AI risks. Per Reuters, their warnings included AI slipping beyond human control.
$4 per million input tokens instead of $5 makes Opus 5.5 look like an easy upgrade, but Anthropic's migration guide lists four changes that make Opus 5 requests fail with 400 errors.
Switching off telemetry in Claude Code also quietly disabled a feature that only reads a local file. AGENTS.md support waits on a remote flag that falls back to false, and nothing tells you the file was skipped.
Anthropic's own advice for Opus 5.5 is to delete "think carefully" from your prompts. When Anthropic cut that line in its chat testing, replies started sooner, with no clear drop in quality.
"More catches, different misses" is how CodeRabbit sums up Opus 5.5 as a code reviewer: in its open-source test, the model found 11 bugs its production reviewer missed and let through nine that reviewer caught.
Claude Code users on Pro, Max and Team just got a spare limit reset they can spend on any bad day before Oct 22, and it comes on top of 5-hour session limits that went up 20% today.
An early tester pointed Claude Opus 5.5 at a 680,000-line code migration and had it done in under a day. It also runs 40% cheaper than Opus 5 at default settings, with cache reads down 60% to $0.20 per million.
Attackers exploited exactly one of 225 CVEs credited to Anthropic's Project Glasswing, a SQL injection in Ghost. That's fewer than 0.5%, says VulnCheck's Patrick Garrity, who has tracked the list since April.
Eighteen months ago Anthropic expected $12 billion of revenue in 2027. By August it was running at around $65 billion annualized, an unofficial figure, and the IPO it was poised to file could value it at $2 trillion.
Tokens, cost, and latency now sit next to every request in Anthropic's Claude API sandbox, renamed from Workbench to Playground, per a Threads post. The SDK code copies out when something works.
Four people who pay for ChatGPT, Claude, Grok or Gemini are suing Anthropic, OpenAI, Google and SpaceXAI, arguing a deal to slow AI down cuts the value of the subscriptions they bought. They want a nationwide class behind them.
The last time the UN Security Council took up AI, in 2023, China warned the technology should not become a "runaway horse". Sam Altman briefs an open Council meeting in person on Wednesday, an OpenAI spokesperson told Reuters.
Anyone budgeting next week's sprint around Claude Code's current weekly cap loses 17% of it on September 14, when the temporary 50% boost expires and a permanent 25% raise over the old baseline takes its place.
"No federal government entity should use a Chinese AI model," said Representative John Moolenaar. The Federal Register's site ran a search on Alibaba's Qwen, a week after the FBI accused Alibaba of copying Anthropic.
