2. OpenAI’s Codex Hits 20M Weekly Active Users

OpenAI revealed that its AI coding tool Codex has reached 20 million weekly active users, along with a 35% quarter-to-date increase in revenue run rate and 50% growth in enterprise revenue run rate. The milestone underscores the surging demand for AI-native coding assistants. Enterprise adoption is accelerating as these tools move from experimentation to critical infrastructure. Source-x

3. StateM Agent Runtime Hits 95.3% Accuracy on Terminal-Bench 2.1

StateM is an agent-native runtime that improves long-horizon agent execution through harness scaling, without changing model weights. It achieved 95.3% raw accuracy on Terminal-Bench 2.1 on a $15 frontier run, addressing common failure modes like losing track of state and skipping procedures. This suggests infrastructure-level improvements can be a powerful lever for agent reliability. Source-huggingface
