Use cases

What this model is useful for

Turn notes into actions

Require a distinction between committed actions and ideas for later discussion. A missing value is better than an invented owner or date.

Make a focused code change

Provide the function, contract and tests that must remain valid. Limit the scope instead of asking for a full-module rewrite.

Answer from an internal guide

Provide the relevant document excerpt and ask for the section supporting each answer. If the rule is absent, the model should say so.

Examples

Prompts you can try

A sample brief — add your own inputs. This page does not generate content or charge your balance.

Prompt for an independent test — no saved Terra response is attached yet.

Meeting notes without invented commitments

This fixture uses fictional people and commitments. Remove personal data from a real request and confirm the table with meeting participants.

Extract an action list from these notes: “Ira will prepare the homepage mockup by October 28. Pavel will check payments after the mockup is ready; no exact date was set. We will discuss moving the blog later. The new registration form launches only after payment checks.”

Return a table with task, owner, due date and dependency. State when an owner or date is missing. Then list unresolved questions separately. Do not turn the blog discussion into an agreed task.

Make the prompt your own

  • Say who will read the guide and what they already know.
  • Ask it to mark where your internal instructions should be linked.

How to check the result

  • Ira is assigned to the mockup with an October 28 due date; Pavel owns payment checks without an invented date.
  • The mockup → payment check → registration launch dependency chain is preserved.
  • Moving the blog remains a discussion item rather than an agreed task.
  • For any showcased answer, retain the exact prompt, full text, gpt-5.6-terra ID, date and recorded usage.

Get started

How to get started

  1. Check the model catalog

    Confirm that gpt-5.6-terra is available to your key. Related family models have different IDs and rates.

  2. Configure a text client

    Use the CLODEx base URL and key from /docs, then select the exact ID. Start without tools or advanced parameters.

  3. Validate the format

    Send a short set of notes and verify that the answer follows the table and leaves unknowns explicit before using real material.

Model and integration

Position in the family

OpenAI describes Terra as balancing capability and cost. It accepts text and images and returns text; the page and CLODEx documentation define the available route.

Why this example is useful

The task has objective checks: whether dates were invented, dependencies were lost or a discussion was turned into a commitment.

What to consider

No access to later decisions

The model cannot see calendars, team chat or decisions made later unless you provide them.

Structured output needs validation

A text table and a verified JSON Schema mode are different. For automation, confirm the route and validate every response.

Balanced does not mean universally best

Terra's positioning does not prove that it is best for your workflow. Measure cost per accepted result.

Before you submit

The model only knows the supplied notes. It cannot know later team decisions and must not turn missing owners or dates into plausible guesses.

Models to compare

GPT-5.6 Sol

gpt-5.6-sol

Compare dependency coverage and reviewer corrections on the same material. Sol is worthwhile only when task complexity justifies the extra usage.

GPT-5.6 Luna

gpt-5.6-luna

Use the same short records plus an ambiguous case. Compare accuracy and cost per successfully processed record.

07

FAQ

Model FAQ

When is Terra enough instead of Sol?

For a scoped task with explicit criteria. If the work has a long dependency chain or expensive failure modes, compare it with Sol on the same input.

Can it handle large documents?

The upstream model has a large context window, but completeness still needs verification. Use named sections and ask about specific conditions.

Can it return a table or JSON?

A table can be requested in plain text. For strict JSON, confirm structured-output support on the route and validate the schema in your application.

Is Terra always cheaper than Sol?

The CLODEx rate is shown on the card, but total cost depends on volume and retries. Compare cost per accepted result, not only the per-token rate.

Do I need an OpenAI subscription?

No. This page uses a CLODEx key and balance. A consumer OpenAI subscription does not automatically provide CLODEx credit.
