GPT-6.1 Terra: OpenAI's fast, half-price model for visual reasoning and computer use
OpenAI released GPT-6.1 Terra on Oct 26, a mid-tier model for visual reasoning, precise computer use and everyday writing, at $1 per million input tokens and $5 per million output tokens — half the API price of GPT-6.1 Sol — with a 1.05M-token context window, rolling out in ChatGPT Work and Codex and generally available in GitHub Copilot.
Why it matters
Vendor-reported 50.3% on Terminal-Bench 4.0 (vs 21.5% for GPT-5.6 Terra) and 3x faster task completion than Sol/Astra, at half the price — a new cost-intelligence point for high-volume agentic work.
What you could build with it
A small automation studio could build an invoice-and-forms processing service that routes high-volume document work to GPT-6.1 Terra's cheaper API and escalates only ambiguous cases to a pricier frontier model, cutting per-document cost while keeping computer-use accuracy for form filling and data entry.
Does it hold up?
Too early to judge for production use — it launched Oct 26 and rollout is still gradual, but same-day Copilot availability gives developers an immediate way to test it on real terminal and coding tasks against GPT-5.6 Terra.
