Anthropic added two sentences to Claude Code on Opus 5.5 so it stops recreating specific existing games. We sent it 16 game requests: it built 14, renamed every famous one, and refused a Mario level.
Anthropic renamed Max 20x to Ultra and removed its 5-hour limit for verified accounts. Pro, Max and Ultra all cost $20 per unit of weekly usage, so the choice is about room, not price.
Anthropic launched Claude Duet on October 21, 2026: a proactive agent app that briefs you each morning, works in its own cloud computer and asks before it sends, pays, signs or deletes. Here is how it compares with OpenAI dots, Meta Muse and Grok Bot.
Anthropic launched Claude Motion in beta on October 8, 2026: describe a chart or explainer, and Claude builds an editable animation you export as an MP4. It is on Team and Enterprise plans only, so it starts at $50 a month.
Claude Haiku 5.5 launched October 7 at $0.10 in and $0.50 out per million tokens, 90% under Haiku 4.5 for most jobs. Here is what that means per podcast show note, caption and browser chore, and when to pick Sonnet 5.5 instead.
Claude Sonnet 5.5 costs half of Opus 5.5 per token and beats it on Terminal-Bench 4.0. At max effort, Artificial Analysis measured $7.60 per task against Opus 5.5's $5.98. Here is how effort decides your bill, and the five breaking changes to fix first.
Anthropic cut Opus pricing 20% and took the number one spot on the Artificial Analysis index. The line that will actually change your bill is the effort default, which dropped from high to medium.
Claude Code v2.1.277 can read AGENTS.md as a project's instruction file, closing the last conspicuous gap in a standard used by 60,000+ repositories. The documentation tells a more conditional story than the changelog does.
Anthropic merged Claude Cowork into Claude chat on September 16, 2026, closing an eight-month split between its conversational assistant and its agentic workspace, and added Claude Docs and Claude Slides as betas.
Anthropic shipped version 1.30.0 of its ant CLI on September 3, 2026, and the headline addition is a single command. ant apply creates and updates agents, environments, skills, memory stores, and scheduled deployments from plain files in your repository.
Claude Mythos 5.1 is the same model as Fable 5.1 running with more permissive safeguards, available only through vetted cybersecurity and life sciences programmes.
Anthropic released Claude Fable 5.1 on September 1, 2026. Headline pricing did not move, but cache reads dropped from $1.00 to $0.25 per million tokens, a 75 percent cut worth up to 45 percent on agentic workloads.
Anthropic will change Claude Code weekly usage limits on September 14, 2026, replacing a temporary 50% boost with a permanent 25% increase over the original baseline. For current users, that is roughly a 17% cut from today's levels.
Anthropic has added a built-in browser to Claude Cowork, its agentic desktop app, so Claude can open websites, click links, and fill forms on its own. Announced August 26, 2026, it stays separate from your personal browser.
The AI assistant you use every day now remembers you by default, and in 2026 that quietly became the feature that separates a chatbot from a working collaborator.
Anthropic unified Claude's memory across Chat and Cowork so context carries between both surfaces, on by default across Free, Pro, and Max, with per-topic controls and sensitive-topic exclusions.
Anthropic moved four agent building blocks to general availability on the Claude Platform on August 20, 2026: computer use, a new browser use tool, the Skills API, and the Files API.
Anthropic turned the Claude Chrome extension into a full Cowork session on August 12, 2026, with shared history, skills, and cross-device handoff.
A new open-source project, gsheets-mcp, gives Claude direct read and write access to your Google Sheets through a small, self-hosted server. Here is how it works, how the 2026 field compares, and how to set it up safely.
Claude Code can now pass messages between your separate sessions. Shipped in v2.1.224 on August 7, 2026, it lets one session hand a finding to another.
Anthropic updated Claude voice mode to run on Opus and Sonnet, not just Haiku, and to act inside Gmail, Calendar, Slack, Canva, and Notion by voice. Here is what changed and how to use it.
Anthropic raised Claude Managed Agents from 20 to 500 skills per session and added five-tier effort controls, making a single agent able to hold a whole knowledge base.
A step-by-step workflow for Claude Cowork's Record a Skill feature: record a repetitive task once while narrating, and Claude turns it into a reusable skill you can rerun on demand.
Anthropic reversed course: Claude Fable 5 will be permanently included in Max and Team Premium plans from July 20, ending the metered usage-credits billing.
