AI is reshaping how startups are being built. Founders who've never written a line of code before are shipping production applications, reaching revenue before scaling headcount, and building tools to automate their most tedious workflows. The founder's role is shifting from individual contributor to orchestrator, allowing them to focus on the work only they can do. We put together a practical pla

The Claude Platform on AWS is now generally available, offering a new way for AWS customers to access the full set of Claude Platform features with AWS authentication, billing, and commitment retirement. Claude also remains available on Amazon Bedrock, where AWS is the data processor. Starting today, Claude Platform on AWS customers can deploy agents at scale with Claude Managed Agents and build w

Claude Security is now available in public beta to Claude Enterprise customers. AI cybersecurity capabilities are advancing fast. Today’s models are already highly effective at finding flaws in software code; the next generation will be more capable still, and will be particularly effective at autonomously exploiting these flaws. Now is the time for organizations to act to improve their security,

Claude reasons through your code like a skilled security researcher. It understands context, traces data flows, and catches vulnerabilities that pattern-matching tools miss. Then it suggests a fix. Claude Security understands context, traces data flows across files, and identifies complex, multi-component vulnerability patterns that traditional scanners might not detect.

https://claude.com/blog/building-agents-that-reach-production-systems-with-mcp Agents are only as useful as the systems they can reach. Teams tend to converge on three approaches for connecting them to external systems—direct API calls, CLIs, and MCP. This post lays out where each fits, why production agents tend to land on MCP, and the patterns for building those integrations effectively. Connect

https://claude.com/blog/best-practices-for-using-claude-opus-4-7-with-claude-code Opus 4.7 is our strongest generally available model to date for coding, enterprise workflows, and long-running agentic tasks. It handles ambiguity better than Opus 4.6, is much more capable at finding bugs and reviewing code, carries context across sessions more reliably, and can reason through ambiguous tasks with l

Today, we're introducing routines in Claude Code in research preview. A routine is a Claude Code automation you configure once — including a prompt, repo, and connectors — and then run on a schedule, from an API call, or in response to an event. Routines run on Claude Code’s web infrastructure, so nothing depends on your laptop being open. Developers already use Claude Code to automate the softwar

In an earlier post, we explored when multi-agent systems provide value and when a single agent is the better choice. This post is for teams that have made that call and now need to decide which coordination pattern fits their problem. We've seen teams choose patterns based on what sounds sophisticated rather than what fits the problem at hand. We recommend starting with the simplest pattern that c

Developers who want to better balance intelligence and cost have converged on what we call the advisor strategy: pair Opus as an advisor with Sonnet or Haiku as an executor. This brings near Opus-level intelligence to your agents while keeping costs near Sonnet levels. Today we're introducing the advisor tool on the Claude Platform to make the advisor strategy a one-line change in your API call. B

Today, we're launching Claude Managed Agents, a suite of composable APIs for building and deploying cloud-hosted agents at scale. Until now, building agents meant spending development cycles on secure infrastructure, state management, permissioning, and reworking your agent loops for every model upgrade. Managed Agents pairs an agent harness tuned for performance with production infrastructure to

Claude Code handles complex, multi-step projects well, but long sessions accumulate weight. Every file read, every tangent explored, every half-finished thought stays in the context window, slowing responses and driving up token costs. Consider building a new feature in a large TypeScript monorepo. The main work is the implementation, but side tasks keep appearing: trace how an existing service ha

One of Anthropic’s co-founders, Chris Olah, says that generative AI systems like Claude are grown more than they are built. Researchers set the conditions to direct growth, but the exact structure or capabilities that emerge aren’t always predictable. This creates a challenge for building with Claude: agent harnesses encode assumptions about what Claude can’t do on its own, but those assumptions g

In Claude Cowork and Claude Code, you can now enable Claude to use your computer to complete tasks. When Claude doesn’t have access to the tools it needs, it will point, click, and navigate what’s on your screen to perform the task itself. It can open files, use the browser, and run dev tools automatically — with no setup required. This feature is now available in research preview for Claude Pro a

Since Claude Sonnet 3.5 (new) in October 2024, I made a habit of testing every new model by asking Claude Code (an internal tool at the time) to add a table tool to Excalidraw. With each new model, Claude got a little further but still failed. Then, with the release of Opus 4 in June 2025, Claude started occasionally succeeding, enough that we turned the exercise into a pre-recorded demo for the C

Anthropic’s developer conferenceJoin us for a day of hands-on workshops, live demos of new capabilities and conversations with the teams behind Claude. Watch live from anywhere, or apply for an in-person seat in San Francisco, London, or Tokyo.

Claude Opus 4.6 and Sonnet 4.6 now include the full 1M context window at standard pricing on the Claude Platform. Standard pricing applies across the full window — $5/$25 per million tokens for Opus 4.6 and $3/$15 for Sonnet 4.6. There's no multiplier: a 900K-token request is billed at the same per-token rate as a 9K one. What's new with general availability: One price, full context window. No lon

Last fall, we previewed Imagine with Claude: a new way for Claude to build visuals in real time, without any code. We’re now bringing a version of this feature, in beta, to Claude’s chat conversations. Claude can create custom charts, diagrams and other visualizations in-line in its responses—and then tweak and modify its creations as the conversation develops. Claude’s conversations already inclu

Today we're introducing Code Review, which dispatches a team of agents on every PR to catch the bugs that skims miss, built for depth, not speed. It's the system we run on nearly every PR at Anthropic. Now in research preview for Team and Enterprise. Managing the review bottleneckCode output per Anthropic engineer has grown 200% in the last year. Code review has become a bottleneck, and we hear th

Bring your preferences and context from other AI providers to Claude. With one copy-paste, Claude updates its memory and picks up right where you left off.

COBOL is everywhere. It handles an estimated 95% of ATM transactions in the US. Hundreds of billions of lines of COBOL run in production every day, powering critical systems in finance, airlines, and government. Despite that, the number of people who understand it shrinks every year. The developers who built these systems retired years ago, and the institutional knowledge they carried left with th

Claude Enterprise gives your entire organization access to Claude, Claude Code, and Cowork — alongside enterprise security and the ability to work with large codebases, extensive document sets, and broad organizational context. Your teams can brainstorm with Claude, delegate coding tasks from the web and terminal, or hand off complex multi-step projects and get back finished deliverables. With Cow
