  1. LLMON: An LLM-Native Markup Language, now in Granite 4.1 3B and 8B

    LLMs rely on their context to generate the next set of tokens. To address this, we developed LLMON (LLM Object Notation, pronounced “lemon”), an LLM-native markup language for explicitly communicating structure and semantics to the models.

OpenAI says GPT-6 Astra designed a hardware device from scratch in under a week

OpenAI's hardware team used GPT-6 Astra to design a device for the Codex coding agent in under a week, handling everything from the enclosure to the circuit board to the firmware. Several revision rounds were needed before production because the model didn't always account for manufacturing tolerances.
