Warp’s big bet on building open source with GPT-5.5

Warp, a modern terminal application, is using GPT-5.5 to power AI agents (software programs that can autonomously plan and execute tasks) that help write code and manage open-source development. In Warp's internal testing, GPT-5.5 uses 30% fewer tokens (units of text that the AI processes) per coding task than GPT-5.4, making the system more efficient as it scales to handle longer, more complex workflows.
