The new alpha of Simon Willison's web-edit app includes performance optimizations written by Claude Opus 5.5. The model worked from a Python 3.15 profiling report that GPT-6 Astra had produced earlier, chaining two labs' models on one task.
Vercel has added Google's Gemini 4 Argon to its AI Gateway. The model targets coding, agentic tasks and complex reasoning, offers a 1M-token context window, takes text, image, PDF and video input, and supports tool calling. It uses low, medium and high thinking levels rather than thinking budgets.
Zapier explains ChatGPT dots, OpenAI's always-on agents, after testing them with a Pro account. The piece places them in a wider race that includes Meta's Muse and Google's Spark, and notes OpenAI hired OpenClaw's developer.
A guide explains how to use Spark, Google's AI tool that carries out tasks on the user's behalf. It is part of Google's push to make Gemini act rather than just chat.
NVIDIA highlights French companies deploying agentic AI in space, financial services, the public sector and scientific research. It credits groundwork such as the February 2025 AI Action Summit and the Choose France summits with anchoring major investments.
Alibaba's Qwen team unveiled QwenGyre, an online reinforcement learning framework that trains coding agents through unmodified, black-box harnesses. It targets rollouts lasting hours and processing close to a million tokens.
