Untenable demand has Anthropic exploring new approaches to rationing its service.
Anthropic secures 5 gigawatts of Amazon’s custom silicon as Claude demand soars.
Anthropic introduces Managed Agents on Claude, a managed execution layer for agent-based workflows. It separates agent logic from runtime concerns like orchestration, sandboxing, state management, and credentials. The system supports long-running multi-step workflows with external tools, error recovery, and session continuity via a meta-harness architecture. By Leela Kumili
The company says Claude Design is intended to help people like founders and product managers without a design background share their ideas more easily.
Anthropic has introduced a new Code Review feature for Claude Code, adding an agent-based pull request review system that analyzes code changes using multiple AI reviewers. By Daniel Dominguez
Anthropic researcher Nicholas Carlini used Claude Code to find a remotely exploitable heap buffer overflow in the Linux kernel's NFS driver, undiscovered for 23 years. Five kernel vulnerabilities have been confirmed so far. Linux kernel maintainers report that AI bug reports have recently shifted from slop to legitimate findings, with security lists now receiving 5-10 valid reports daily. By Steef
New model is the first AI system to complete a difficult multistep infiltration challenge.
A recent paper from Anthropic examines how large language models internally represent concepts related to emotions and how these representations influence behavior. The work is part of the company’s interpretability research and focuses on analyzing internal activations in Claude Sonnet 4.5 to understand the mechanisms behind model responses better.

Anthropic has introduced Claude Mythos Preview, its most advanced AI model, improving significantly in reasoning, coding, and cybersecurity. Unlike previous releases, it will not be publicly available. Access is limited to a consortium of tech companies through Project Glasswing. Internal tests revealed the model's ability to discover critical security flaws effectively. By Daniel Curtis
This ban took place after Claude's pricing changed for OpenClaw users last week.
Mythos is "the most psychologically settled model we have trained to date."
A select group of customers is testing the Claude Mythos Preview.
Anthropic bulked up its compute deal with Google and Broadcom as the company has seen its run-rate revenue surge to $30 billion.
Designed to manage concurrent agents running in containers across local and remote compute, Scion is an experimental orchestration testbed that enables developers to run groups of specialized agents with isolated identities, credentials, and shared workspaces. By Sergio De Simone
Anthropic's Claude Code CLI had its full TypeScript source exposed after a source map file was accidentally included in version 2.1.88 of its npm package. The 512,000-line codebase was archived to GitHub within hours. Anthropic called it a packaging error caused by human error. The leak revealed unreleased features, internal model codenames, and multi-agent orchestration architecture. By Steef-Jan
A 600-run benchmark by Ruby committer Yusuke Endoh tested Claude Code across 13 languages, implementing a simplified Git. Ruby, Python, and JavaScript were the fastest and cheapest, at $0.36- $0.39 per run. Statistically typed languages cost 1.4-2.6x more. Adding type checkers to dynamic languages imposed 1.6-3.2x slowdowns. Full dataset available on GitHub. By Steef-Jan Wiggers
Anthropic has purchased the stealth biotech AI startup Coefficient Bio in a $400 million stock deal, according to The Information and Eric Newcomer.
