OpenAI's API spec now lists a new model: gpt-5.1-mini. This is a strong signal for an upcoming, unannounced model.
READY TO POST:
looks like openai just added 'gpt-5.1-mini' to their api spec. a new model on the horizon?
whoa, spotted gpt-5.1-mini in the openai api. could be a smaller, faster version of gpt-5.1?
