Why we said Use
What it is
A model API surface with usage billed at the selected model and tool rates. See the official documentation or product page. This profile describes public documentation, not a Loaded Tokens hands-on test.
Who it is for
Developers embedding model calls and tools in applications. Our recommendation is scoped to that job; it is not a universal winner.
The evidence behind Use
For builders who need an application API rather than a chat subscription, the rate card makes the unit of cost explicit. The vendor page documents the underlying capability; the fit judgment is ours. No performance ranking, time saving or reliability result is implied.
Pricing and the catch
No separate Responses API fee; model tokens and tool usage are billed. Example: GPT-6.1 Terra standard short-context $1/M input and $5/M output tokens. Public pricing checked November 7, 2026. Prices are USD where stated and can change; taxes, region, annual commitments and extra usage may differ.
Search, storage, tool calls and processing tiers can add charges beyond text input and output.
A sensible first workflow
Define a bounded extraction job with a schema, a spending limit and a rejection path. This is a suggested evaluation, not a test we ran. Decide what success looks like before opening the tool: what output is acceptable, what needs review and where the workflow must stop.
Bottom line: buy for the job, keep the exit route, and do not confuse a feature list with proof of results. Browse the company profile for the rest of the stack.
