OpenAI published a case study on Warp's open-source release, powered by GPT-5.5 agentic workflows via its Oz cloud orchestration platform. In Warp's own engineering org, agents now co-create around 90% of pull requests — humans define objectives and supervise outcomes while agents plan, write code, test, and open PRs. GPT-5.5 uses 30% fewer tokens per agentic coding task than GPT-5.4, and OpenAI is the founding sponsor of the open-source repository.
