Warp Bets on Building Open Source with GPT-5.5

Warp is using GPT-5.5 to orchestrate agents across local, cloud, and open source workflows. Recently, it open-sourced its terminal client and introduced the Open Agentic Development model, in which humans set goals and agents write code, run tests, and create PRs.

GPT-5.5 plays a key role in enabling agents to reason over a broader problem space and prepare deliverables. According to internal benchmarks, GPT-5.5 achieved a 30% reduction in token usage compared to GPT-5.4 on agentic coding tasks, improving the efficiency of large-scale agentic workflows.

Currently, within Warp's internal engineering organization, agents co-generate approximately 90% of all Pull Requests (PRs). To support this, Warp built Oz, a cloud orchestration platform for deploying and managing agents across local and cloud environments.

Going forward, software development is expected to evolve toward a model where developers specify intent, agents write the code, and humans verify and judge the final output. In this model, open source is set to shift from humans directly handling implementation to humans contributing product judgment and shared vision instead.
