Existing laws covering contracts, liability, consumer protection and data governance are being pushed well beyond their original design. Particular unease surrounds agent to agent interactions and the question of who is responsible when automated systems fail. With oversight still grounded in high level principles and voluntary guidelines, momentum is building for risk based regulation and sandboxed experimentation.

That tension between capability, access and control shaped the AI agenda this week. Here are the key developments from across the industry:

OpenAI expands Codex into a more capable AI work partner

OpenAI has rolled out a major update to Codex, pushing it beyond coding assistance and closer to a broader AI work partner for the more than 3 million developers who use it each week. Codex can now operate a user’s computer in the background, with its own cursor, and work across everyday apps, generate images, remember preferences, and take on longer-running tasks over days or weeks.
