Introducing support for GPT-5.1 in Warp

Support for OpenAI's latest model, GPT-5.1, is now available in Warp, becoming the default model for new users due to its impressive capabilities demonstrated during extensive testing. GPT-5.1 is an enhancement of GPT-5, offering significant improvements in speed through adaptive reasoning, which allows the model to adjust its reasoning based on task complexity. This results in a 15% faster time to first token and 40% faster task completion, while maintaining high-quality output and excelling in deep debugging scenarios. The development of GPT-5.1 in collaboration with OpenAI included optimizing prompt structure and tool definitions, ensuring a balance between planning and execution within the terminal. To encourage developers to try GPT-5.1, Warp is offering a promotional code for a discounted first month of Warp Build to the first 510 users.
