The Earendil team released Pi 1.0 and Pi Durable, both of which reached the front page of Hacker News. Pi 1.0 introduces native support for MCP, Jev, and image models via Codemode, along with extension support for virtual models and deferred tool loading.
Pi Durable ports Pi to TypeScript and externalizes stateful components to enable crash survival, portability across JavaScript runtimes, concurrency, and hot-swapping of tools. Meanwhile, Google announced Gemini 4 Argon with revised pretraining and internal testing protocols, while OpenAI released GPT-6.1 Sol as an efficiency-focused update.
Black Forest Labs launched FLUX 3 Image with native 4K generation and bounding-box control, and Upstage introduced Solar Mini 4, a reasoning model with a 1M-token context window.
