Editorial Analysis
Profile. GPT-5.6 Terra (high) is positioned in the mid-tier at $12.00/M output tokens. The benchmark profile is balanced — strongest on Coding Index (67.1) — making it a default choice for teams that need general-purpose reasoning without paying frontier-model prices.
Latency. On latency, GPT-5.6 Terra (high) reports 103 tok/s output speed and 2330ms time-to-first-token. Output speed is in the normal range — most chat and completion applications will be token-bound, not streaming-bound.
Cost model. For a workload of 1M input tokens + 100K output tokens, GPT-5.6 Terra (high) costs $3.20 per million input-equivalent requests. Multiply by your monthly request volume to project the bill, and compare against the speed/correctness profile above to decide if the trade-off is worth it for your workload.
