## [Copy link to heading](#about-gpt-5)About GPT-5

GPT-5 launched on August 7, 2025 as a generational leap over the GPT-4 family. Available through AI Gateway, it brings together advances in reasoning depth, coding proficiency, instruction following, and multimodal understanding in a single model.

The model supports a context window of 400K tokens, enabling developers to pass extensive codebases, long documents, or rich conversation histories in a single request. Combined with improved instruction adherence, GPT-5 follows complex multi-constraint specifications more reliably than its predecessors.

As the standard tier of the GPT-5 family, it sits alongside GPT-5 mini, GPT-5 nano, and GPT-5 pro, each targeting different points on the capability-cost spectrum. GPT-5 is the default choice when full GPT-5 family capability is the priority.
