GPT-6.1 Terra
A good performance / EU-hosting balance for a European company.
Overview
GPT-6.1 Terra is OpenAI's model built for agents, coding and computer use, with a 1.05-million-token context window and text and image input. It is offered in ChatGPT and Codex on paid plans, and via API on request, at an announced price half that of GPT-6.1 Sol. Its performance is measured by Artificial Analysis. The model has closed weights: data goes through OpenAI's infrastructure, except for regional processing in Europe where available.
