Agent Plugins Standard Launches
AWS, Cursor, GitHub, Microsoft, OpenAI, and Vercel jointly announced Agent Plugins, an open packaging standard for extending agents across clients.
One format, many clients: A plugin is a folder with aplugin.json
manifest that bundles Agent Skills and MCP server configs, loadable by any compatible client.Launch support: ChatGPT, Codex, GitHub Copilot, VS Code, Cursor, and Kiro all read the same package on day one.Why it matters: Until now every product used its own folder layout and install flow, forcing builders to repackage the same extension per platform.Governance: The spec is public with a technical steering committee spanning Amazon, Cursor, Microsoft, OpenAI, and Vercel, with proposals handled in the open.
Alibaba Launches Qwen3.8-Max
Alibaba released Qwen3.8-Max, its largest flagship model, aimed squarely at long-horizon coding and professional work.
Scale: 2.4T total parameters with 95B active and a 1-million-token context window, built on the Qwen3.5 architecture.Agentic benchmarks: 86.6 on TerminalBench 2.1, 86.1 on OSWorld-Verified, 93.0 on PaperBench, and 74.8 on CoWorkBench.Long-horizon evidence: A roughly 16-day autonomous run on the oh-my-cli project produced 265 commits, 127 pull requests, and 151 issues, and the model beat 458 of 526 human teams in a multimodal dialogue challenge.Availability: Live on QwenCloud with OpenAI and Anthropic protocol support plus Claude Code, Codex, Qoder CLI, and OpenClaw integrations, with open weights promised alongside Qwen3.8-27B.
