Anthropic has updated its usage guidelines to forbid severe and continuous mistreatment directed at its Claude assistant. The model now holds the ability to end conversations automatically when encountering persistent hostility. Additional terms mandate human supervision and automatic safety stops for machines guided by Claude.

Anthropic mathematician Levent Alpoge commented on OpenAI's recent publications, noting the major impact of claimed proofs for longstanding mathematical questions. He noted that AI progress in mathematics is accelerating faster than expected across rival research teams.

Anthropic launched a thirteen lesson public course explaining common reasons modern language models generate errors or lose context during extended interactions. The training material requires no prior technical background and aims to help users evaluate output reliability.

President Donald Trump hosted Anthropic chief executive Dario Amodei for a private dinner at the White House. The personal invitation follows recent friction between the administration and the artificial intelligence startup. The dinner precedes an official meeting between government leaders and top technology executives.

Anthropic has released Claude Opus 5.5, engineered to deliver top performance while cutting processing costs by 40 percent compared to Opus 5. The model features more natural writing output alongside increased daily limit caps and on demand reset options for subscribers.

Anthropic published technical documentation covering best practices for controlling long tasks and evaluating output quality in Claude Opus 5.5. The article generated strong interest among developers seeking to optimize agent operations.

Anthropic has delayed its initial public offering to November in order to include third quarter financial results in its regulatory filings. The company expects annualized revenue to reach 100 billion dollars by the end of the year and may launch updated frontier models to highlight product progress.

The discovery of unauthorized tracking code led to platform blocks on Anthropic tools in China. State media outlets subsequently raised concerns regarding potential data sharing between US developers and government intelligence.

Anthropic updated Claude to eliminate the requirement of manually switching between standard chat mode and co-working mode. Users now interact with a single unified interface that automatically adjusts to the task at hand.

Leaders from top AI companies have publicly backed a proposal by Anthropic Chief Executive Dario Amodei to pace the development of frontier artificial intelligence models. The plan advocates for third party safety evaluators embedded within companies and unified safety benchmarks to prevent risks from emerging autonomous systems.

A researcher who worked on AI pretraining at OpenAI and Anthropic publicly resigned, claiming both companies are recklessly rushing toward self improving superintelligence. His public posts ignited a broad debate on existential risk and how tech leaders view safety behind closed doors.

Following the public resignation thread, Anthropic alignment researcher Evan Hubinger stated he believes there is a greater than ten percent chance AI could lead to human extinction within ten years. He clarified that the danger stems from future recursively self improving systems rather than existing models.

Former pretraining researcher Jacob Coxon left Anthropic to publicly highlight safety concerns around rapid artificial intelligence development. He expressed worry that intense commercial rivalry forces labs to skip safety testing as models approach recursive self improvement.

Anthropic has reduced the prices charged for reading cached data when using its Fable 5.1 model framework. The price reduction cuts general running costs by approximately one quarter for standard daily usage.

Anthropic rolled out background task processing for Claude Cowork and Claude Code, allowing the assistant to handle desktop automation while users focus on other assignments. The feature is available in preview mode for paid subscribers on macOS for approved applications.

Anthropic has launched Claude Fable 5.1, an upgraded model built for complex coding, multi-step workflows, and professional knowledge tasks. The release costs roughly 25 percent less on token billing than its predecessor while reducing false security blocks by 60 percent. Anthropic also opened early access for its Mythos 5.1 model to select partners.

Claude can now automatically retain user preferences and context across chat sessions without losing background information. Stored details sync automatically between Claude and Cowork, while users can edit or remove saved memories from their account settings at any time.
