Model Updates & Workflows

Pi 0.99.0 发布，还更新了挺多东西的🔥 这次可以说是一个比较大版本的更新，更新的几个点我都比较在意，我把它整理出来了 1、MCP 正式内置，但是做法很 Pi 这次直接加入 Codemode、MCP 和 Tool Search。 模型可以自己写 JavaScript，在 QuickJS 沙箱里一次调用多个 Tool，甚至并行执行。 https://t.co/87KWhVw4bx

Anthropic

@AnthropicAI

What do you want from AI? We’re launching a new study with Anthropic Interviewer to learn more about your experiences using AI, what role you want it to play in your life and the world, and what you want from the companies building it. Last December, 81,000 people told us about their hopes and fears about AI in the largest qualitative study ever done. This time, we’re giving participants the option to make their responses public so that anyone, not just Anthropic, can learn from them. What you tell us will shape The Anthropic Institute’s research and inform the decisions we make. If many people say companies like Anthropic should be doing something differently, that will be on the record, where anyone can point to it. The study runs Sept 29 to Oct 6 and is open to Free, Pro, and Max users on Claude and Claude Code. Take part here: https://t.co/MtdU7MZbeY

You always stay in control. Set boundaries and specify what your dot can do on its own, when it should ask first, and what it should never do. Safety is built in. You choose which apps to connect, and your dot runs on its own cloud computer—so connecting yours is entirely optional. https://t.co/0ZjtBVXMSo

GPT-6.1 Sol shows major improvements over GPT-6 Sol in our alignment evaluations, bringing it more in line with GPT-6 Astra. It’s more transparent about its limitations and more reliable at respecting user intent and safety constraints. https://t.co/1XWstBUXpW
