GPT Terra
OpenAI's mid-tier line, priced between Sol and Astra on output.
GPT Terra is OpenAI's middle line: $2 in / $12 out per MTok, between Sol and Astra on output price. OpenAI's pages carry no positioning for it beyond the price and the long-context tiers.
What it is good at
- A mid tier at $2 in / $12 out per MTok when a step needs more than Sol
What it is less good at
- No benchmarks published by OpenAI, and no positioning on its own model pages

Versions
One block per version, the current one first, each with its own anchor. The comparison table puts the costs and the family's benchmark columns side by side; the values are verbatim, and every one is sourced and dated in its version's section below and in the Sources list. A dash means the source publishes no figure, and nothing here is estimated.
No independent intelligence or speed index is republished here: Artificial Analysis measures both across labs, and its terms allow the link but not the copy — its figures live on its own pages.
