Overview

GPT-6.1 Terra is the balanced, mid-tier level of OpenAI's GPT-6.1 series — in the series' naming convention, Terra denotes the variant with a balanced quality-to-cost-and-latency trade-off, intended for everyday production work: coding, reasoning and agentic tasks.

The model is multimodal (accepting text and image among others, generating text) and offered as a closed cloud service via the API and within OpenAI products; the model weights are not publicly available.

Detailed technical parameters (context window, maximum output tokens, knowledge cutoff, reasoning levels) are given in OpenAI's official announcement — see the source.
