GLM-5.2

Z.ai launched GLM-5.2 with a 1 million-token context window, new reasoning controls, and support for long-horizon coding tasks across entire codebases. The company made the model available immediately to Coding Plan users and plans to release API access, chatbot support, technical details, and MIT-licensed open weights the following week. Z.ai positions GLM-5.2 as a coding-first upgrade focused on agentic software engineering, though it did not publish benchmark results at launch.

LEVIATHAN WAKING

The US government spent a long time being complacent about AI regulation. Anthropic's development of advanced models has caused a stir. The administration's response was incomprehensibly strict and risk-averse, especially after its previous attitude towards risk in the industry. It has been unclear about its policies, and disputes about policy and politics between the administration and Anthropic remain unresolved.

CURSOR ORIGIN

Cursor Origin is an attempt at an agent-native GitHub competitor. The Git-compatible forge is built around the assumption that lots of AI agents will be cloning, branching, committing, rebasing, reviewing, and fixing failures in parallel. Cursor is trying to own the whole AI software factory. GitHub was built for human-scale development, but Origin was built for agent-scale.

OPENAI RELEASED CDP SUPPORT FOR BROWSER USE ON CODEX

OpenAI's Codex now supports Chrome DevTools Protocol, enabling live browser access to profile JavaScript performance and modify websites in real time. This early-stage feature, available via opt-in settings but excluded from the EEA, UK, and Switzerland, faces performance issues and requires careful prompting. Recent OpenAI moves, such as acquiring Ona, aim to create persistent cloud environments, highlighting a push toward an AI-driven web.
