We've published a paper that explains our views on AI competition between the US and China.
The US and democratic allies hold the lead in frontier AI today. Read more on what it’ll take to keep that lead: https://t.co/TgJBeodWYK
How can we autonomously improve LLM harnesses on problems humans are actively working on?
Doing so requires solving a hard, long-horizon credit-assignment problem over all prior code, traces, and scores.
Announcing Meta-Harness: a method for optimizing harnesses end-to-end
1/4 We are thrilled to announce that CoPaw is now open source! After an incredible wave of feedback, our team has completely overhauled the engine to give you full control over your personal AI partner.
Key Highlights:
Ultimate Model Freedom
Local-First: Full native support for Ollama, llama.cpp, and MLX (Apple Silicon).
Bring Your Own Model: Easily add/remove custom model providers or private API endpoints. Your data, your choice.
Smarter Long-Term Memory
No more "amnesia." CoPaw remembers your preferences and tasks.
New Local Mode: Use vector search without complex database installs—now fully compatible with Windows for an out-of-the-box experience.
Modular "Lego-Like" Architecture
Skill Hub Integration: Import skills from community hubs like ClawHub with one command.
Agentic Workflow: Modularized Prompts, Hooks, and Tools. Supports MCP (Model Context Protocol) hot-swapping—expand capabilities without restarting.
Proactive Multi-Channel Connection
Connect to DingTalk, Feishu, Discord, iMessage, and more.
A new standardized protocol makes it easier than ever to build your own channel plugins.
Mercury 2 is live 🚀🚀
The world’s first reasoning diffusion LLM, delivering 5x faster performance than leading speed-optimized LLMs.
Watching the team turn years of research into a real product never gets old, and I’m incredibly proud of what we’ve built.
We’re just getting started on what diffusion can do for language.
Hello!
Today we're releasing Paper Desktop
Paper is now a canvas for Cursor, Claude Code, Codex. Any agent can read and write html to Paper.
• push or pull from your codebase
• pull real data from anywhere
• less work, more design
What will you ship? Sound on 🎶
New Engineering blog: We tasked Opus 4.6 using agent teams to build a C compiler. Then we (mostly) walked away. Two weeks later, it worked on the Linux kernel.
Here's what it taught us about the future of autonomous software development.

Excited to release my new Image Generator skill.
It's an effective way to improve image generation using coding agents like Claude Code.
I use this for all image generation workflows now. It's powered by Nano Banana Pro.
You can improve the process further (through more precise annotations) with the new Claude Code Playground plugin.
I refer to this process as Agentic Image Generation, and wrote a little tutorial if you are interested: https://t.co/mjxa48fhTs
