GritAI Newsletter: Opus 4.7, Claude Design, Mythos, and the race with OpenAI πŸ‘Ÿ


Hey πŸ‘‹

The newsletter has slipped a few weeks because we have been running around like crazy talking about Claude, Cowork, Claude Code and Skills πŸš€ Next Monday we run our next Claude Code Bootcamp at Mesh Oslo, followed by a Claude Code Meetup the same evening. This one is big πŸ”₯

Anthropic has shipped a whole lot since our last newsletter

  • New Model Opus 4.7 with better instruction following and more
  • Claude Design turns a prompt into high-quality slides and prototypes
  • Managed Agents lets companies build always-on agents
  • Claude Cowork is not generally available (no more research preview)

Anthropic also published a 244-page model description for a model it will not sell (yet). Claude Mythos Preview found a 27-year-old vulnerability in OpenBSD, the codebase famous for being the most-audited open source OS on the planet. Thousands of human security researchers missed it. An AI did not. Fascinating and scary at the same time!

OpenAI has not slowed down either.

Workspace Agents launched today. Teams can now build and share custom agents inside ChatGPT, powered by Codex and running in the cloud. This is OpenAI’s direct answer to Anthropic’s Cowork. Chronicle watches your screen and builds a searchable memory of everything you do. And ChatGPT Image 2.0 took over every feed this week. In short the best image model in the world now way ahead of Nano Banana 🍌 on benchmarks .

Let us dive in πŸ„

Claude "Superpowers" πŸ’ͺ

The Superpowers plugin gives Claude Code a structured workflow from brainstorming to implementation and testing. This tutorial covers installation, the 7-phase workflow, all 14 skills, the Visual Companion for browser-based mockups, the spec review loop, TDD with the Iron Law, and tips for getting the most out of it.

AI Pulse 🚨

A bite-sized curation of this week's most important AI news.

πŸ‘₯ OpenAI launches Workspace Agents in ChatGPT. Teams build shared agents that handle complex tasks and long-running workflows. Powered by Codex, runs in the cloud. Available in Business, Enterprise, Edu, and Teachers plans.

πŸ‘οΈ OpenAI announces Chronicle. Background agents that watch your screen and build a searchable memory of everything you do. Captures are stored on-device, but other apps can access the files.

🧠 Anthropic releases Claude Opus 4.7. Smarter at following instructions, checks its own work before responding, and can now read dense screenshots and diagrams in high resolution.

🎨 Anthropic launches Claude Design in research preview. Describe what you want and it builds slides, wireframes, and one-pagers. It reads your brand from existing files and applies it automatically.

πŸ€– Anthropic ships Managed Agents in public beta. Build a custom AI agent, give it tools and instructions, and let it run in the cloud without your laptop open.

πŸ§ͺ Anthropic launches Mythos Preview, codenamed Project Glasswing. A security-focused model that finds software vulnerabilities. Found a 27-year-old bug in OpenBSD. Restricted access only.

πŸ’Ό Claude Cowork now GA for all paid plans. Desktop tool that lets non-developers automate file and task management using AI. Previously in limited preview.

πŸ“Š Live Artifacts ship inside Claude Cowork. Build a dashboard once, it auto-refreshes from your real files and apps with full version history.

πŸ”₯ Meta unveils Muse Spark. Scores 58% on Humanity’s Last Exam, 10x more efficient than Llama 4 Maverick. The first Meta model to compete at the frontier since Llama 4.

πŸ’» Cursor 3 ships with an agent-first interface. Manage multiple AI agents across your local machine, remote servers, and cloud. No longer a code editor with AI on the side.

πŸ–₯️ OpenAI expands Codex to a desktop agent on macOS. Reads your screen, controls your cursor, runs background tasks, and supports 90+ plugins. Direct competitor to Claude computer use.

✏️ Claude for Word launches on Pro and Max plans. Claude lives inside your document with clickable citations and tracked changes.

πŸ“Ž Microsoft 365 connectors now available on all Claude plans. Connect Claude to your Outlook, Teams, SharePoint, and OneDrive.

Claude Code Updates πŸ¦€

Here are the highlights from the changelog since our last issue.

πŸ”„ Routines: always-on automation. Bundle a prompt, repos, and tools into one config. Trigger on a schedule, via API, or from GitHub events. Runs in the cloud without your machine.

πŸ‘€ Monitor tool: stream background events into your session. Tail a log, watch CI on a PR, or babysit a training run. Each event lands as a new message Claude reacts to. No more bash sleep loops.

πŸ”€ PR autofix from your terminal. Run /autofix-pr in the CLI to turn on auto-fix for the current branch’s PR. Claude watches CI and pushes fixes in the cloud until it is green.

πŸ–₯️ Desktop rebuild for multi-session workflows. Claude Code desktop now supports multiple parallel sessions and in-app development tools.

πŸ” /ultrareview: deep code review in the cloud. Runs multiple agents in parallel to analyze your branch or a specific pull request. Think code review on autopilot.

πŸ“‹ /ultraplan: cloud-based planning. Kick off plan mode in the cloud from your terminal. Claude drafts the plan while your CLI stays free. Review and comment on individual sections in the browser before execution.

πŸ“² Push notifications via Remote Control. Claude can now send a notification to your phone when it needs your attention or finishes a task. Enable it in settings under Remote Control.

πŸ” Session recap when you come back. Leave a session, come back later, and Claude gives you a summary of where you left off. No more scrolling to remember what you were doing.

⚑ Native binary for faster startup. Claude Code now runs as a compiled binary instead of JavaScript. Noticeably faster to launch, especially on large projects.

Hey πŸ‘‹ Anthropic is now worth more than OpenAI on paper 🀯 Secondary shares priced the company at $1 trillion versus OpenAI's $880 billion, and Google added up to $40 billion on top at a $350 billion paper valuation. The numbers are getting hard to take seriously, but investors are clearly betting that Anthropic catches OpenAI on revenue too. OpenAI is not standing still either. GPT-5.5 is a very good model that we have leaned on hard since it launched. It has been particularly impressive on...

Hey πŸ‘‹ The question on every feed this week is no longer "which AI do you use?" It is "which agent are you running?" The Claude Code team is shipping like crazy. Recurring task loops, background agents, multi-agent teams, remote control from your phone, and you can now start brand new sessions straight from the Claude mobile app. These are the same autonomous capabilities that made OpenClaw explode in popularity, but shipped inside a tool backed by a leading frontier lab. And it is not just...

They also rolled out Skills for ChatGPT, letting teams turn workflows into reusable instructions. Finally! At the same time, more people are now signing up for Claude than ChatGPT.
