Poe API

GPT-5

OpenAI’s most advanced general model with significantly improved coding skills, long context (400k tokens), and improved instruction following. Supports native vision, and generally has more intelligence than GPT-4.1. Provides a 90% chat history cache discount. Optional parameters: Set reasoning effort: Select from `minimal`, `low`, `medium`, `high`. Minimal reasoning effort is set by default. Set web search and real-time information access: toggle it on, otherwise it is off by default.
