Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.

New in Claude Code (research preview): dynamic workflows. Claude writes an orchestration script on the fly, then spins up a large fleet of coordinated subagents in parallel to take on your most complex tasks. Use the word "workflow" in a prompt to get started.

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors. Available today at the same price.

Heads up: Anthropic ends subsidized pricing June 15. @coworkerapp just launched the solution.

Today, we dropped the price of enterprise AI by 80%. Same frontier AI. Same chat, cowork, and code experience. Just 5x more tokens for the same spend. Here’s how and why. 👇 Also, we made a video. Please enjoy.

VS Code was already used by millions of developers for agentic coding. However, the editor layout has traditionally been optimized for single-task and single-workspace workflows. Today, we're introducing a new window to enable our users (and ourselves!) to work with multiple agents across multiple projects: Agents. Now available in VS Code stable!

Today we're sharing our work on interaction models. A new class of model trained from scratch to handle real-time interaction natively, instead of gluing it onto a turn-based one. youtu.be/A12AVongNN4

Hey @mattpocockuk, have you used /loop, /batch or /schedule skills? What about /ultraplan?

Build and deploy your agents through the Claude Console, Claude Code, or our new CLI: platform.claude.com/workspac… Read more on the blog: claude.com/blog/claude-manag…

Introducing Claude Managed Agents: everything you need to build and deploy agents at scale. It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days. Now in public beta on the Claude Platform.

Muse Spark is the first step on our scaling ladder and the first product of a ground-up overhaul of our AI efforts. It offers competitive performance in multimodal perception, reasoning, health, and agentic tasks. We continue to invest in areas with current performance gaps, specifically long-horizon agentic systems and coding workflows. With larger models in development, these results demonstrate that our stack is scaling effectively.

holy shit anthropic just revealed Claude Mythos, a brand new model thats already found 1000s of high-severity vulnerabilities across major operating systems 🙂 they're releasing a new claude opus model POWERED by mythos imminently but look at this shit: - mythos found a major bug in a 27-year old firewall operating system used to secure organizations all over the world - mythos found a way to chain vulnerabilities together to take over entire computer systems, something elite hackers could only do. they are NOT releasing the full mythos model because its too dangerous fucking hell lol. anthropic is committing $100M across 40 partners to battle-test security systems with mythos before releasing it to the public cyber-security AGI is apparently here

We released Claude Opus 4.6 just two months ago. Today we're sharing some info on our new model, Claude Mythos Preview.
