MiniMax's M3.1 Flash, a faster tier of the M3 line that can read images and works on complex tasks, with notable gains over M3 in Agent: An AI that doesn't just answer but takes steps on its own to finish a task: searching the web, running code or using apps. work, coding and cybersecurity, listed on OpenRouter: A service that gives developers one place to use hundreds of models from many labs. New models often appear there early, sometimes anonymously..
Model ID: The exact name developers type to use a model, like gpt-5-mini. New IDs often show up in a lab's systems before the official announcement, which is how trckr spots many releases early.
