OpenAI and Anthropic Push Deeper Into the Developer Workflow

OpenAI agreed on November 4 to acquire Pierre, the company behind Code Storage and open source libraries that Codex uses to browse files and review changes, as it aims to make Codex the place where developers work from the first agent branch through deployment. Analyst Benedict Evans notes that over 80% of Anthropic's third-quarter revenue came from models released in the previous six months, which gives labs a strong incentive to lock in developers across the full workflow. The article argues developers should avoid tying their workflows too tightly to one vendor and should favor shared platforms where competing agents can work together.

Why it matters: Choosing an AI coding agent is increasingly a long-term platform commitment, so teams should weigh lock-in and multi-agent interoperability alongside model quality.
