GPT-5.6 sol vs terra
Choose between gpt-5.6-sol and gpt-5.6-terra with an explicit API test plan. Compare observed results without assuming performance from model names.
Sol and terra are separate published request identifiers. Do not assume that either suffix guarantees a particular speed, reasoning budget or quality tier.
Run a controlled variant trial
Send the same small prompt first to gpt-5.6-sol, then to gpt-5.6-terra. Verify returned identity and completed output. Repeat on your real evaluation set, including edge cases.
curl --fail-with-body https://api.useinfergate.com/v1/responses \

-H "Content-Type: application/json" \
-d '{"model":"gpt-5.6-sol","input":"Reply with one sentence about API design.","max_output_tokens":256}'Decision record
- Task pass rate: score against criteria established in advance.
- Latency: record both first text and completed response times.
- Cost: use actual usage logs and current rates.
- Streaming: require a completion event and useful text, not just HTTP 200.

Prepaid usage and costs
API usage consumes available account credit. Review current input and output rates in application pricing before running a workload. This page does not promise free requests or a fixed discount. See how prepaid pricing works and compare actual usage logs after a small test.
Evaluation worksheet
| Measure | How to collect it | Interpretation |
|---|---|---|
| Task correctness | Score outputs against a fixed rubric | Prefer repeatable task success over a single impressive answer |
| Completion | Record status and useful text | Count incomplete responses separately |
| Latency | Record first-text and completion times | Use a distribution, not one fastest sample |
| Cost | Reconcile completed requests with usage records | Compare cost per successful task |

Which model should I choose?
Choose from your task results, current account access and observed cost. The page provides a test method, not unsupported performance rankings.
Can I compare models using only one prompt?
One request is useful for checking connectivity and identity. It is insufficient for a quality or latency ranking. Include representative tasks and repeated runs.
Should I use identical settings?
Keep inputs and output budgets comparable, and record any settings that differ. Do not force optional parameters onto a model before confirming support.
