OpenAI has released GPT‑6.1 Terra, a fast, efficient model that emphasizes detailed visual reasoning and precise computer use while offering clearer, more natural writing. It is positioned as a mid‑range option—cheaper than Sol but smarter than Luna—suitable for tasks like drafting proposals, interpreting technical drawings, filling out forms, and editing videos. The model is priced at $1 per million input tokens and $5 per million output tokens, roughly half the cost of its predecessor GPT‑5.6 Terra.
Explore lower GPT‑5. 6 pricing for Luna and Terra—and how OpenAI’s more efficient models help enterprises deploy AI workflows at scale.
The OpenAI Blog announces that GPT‑6 enhances prompt caching, achieving higher cache hit rates and introducing new diagnostics, explicit breakpoints, and controls. These features are designed to reduce latency and costs for users. The post highlights the technical improvements that make GPT‑6 more efficient and cost‑effective.
Introducing GPT-5. 5, our smartest model yet—faster, more capable, and built for complex tasks like coding, research, and data analysis across tools.
See how a group of leading developers use GPT-5 for the first time.
The article explains how startups can select GPT‑6 models and adjust their reasoning effort. It offers guidance on improving prompts and skills, coordinating tools, and preparing production workflows.
GPT-5. 1 is now available in the API, bringing faster adaptive reasoning, extended prompt caching, improved coding performance, and new apply_patch and shell tools.
