Whether 9.0 points is worth that depends on how much a wrong answer costs you. Qwen3.6 Plus also leads on measured cost per point of capability, at $0.1262 per point.
Is GPT-5.6 Terra cheaper than Qwen3.6 Plus?
Qwen3.6 Plus is cheaper. On a 3:1 input:output blend, GPT-5.6 Terra lists at $4.50 per million tokens and Qwen3.6 Plus at $0.731 — Qwen3.6 Plus is 6.2× cheaper. Input and output are priced separately — GPT-5.6 Terra charges $2.00 in and $12.00 out, Qwen3.6 Plus charges $0.325 and $1.95 — so the model that looks cheaper flips depending on how output-heavy your workload is.
GPT-5.6 Terra vs Qwen3.6 Plus: which scores higher on benchmarks?
GPT-5.6 Terra scores 77.9 and Qwen3.6 Plus scores 68.9 overall on LiveBench, the mean of its seven categories. That is a 9.0-point lead for GPT-5.6 Terra. Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.
Which gives better value for money, GPT-5.6 Terra or Qwen3.6 Plus?
Qwen3.6 Plus. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. GPT-5.6 Terra works out at $0.1939 per point and Qwen3.6 Plus at $0.1262.
Does GPT-5.6 Terra or Qwen3.6 Plus have a bigger context window?
They are effectively the same — 1.1M for GPT-5.6 Terra and 1M for Qwen3.6 Plus.
Do GPT-5.6 Terra and Qwen3.6 Plus support prompt caching?
GPT-5.6 Terra publishes a cached-input rate of $0.200 per million tokens against a full input rate of $2.00. The catalogue lists no separate cached rate for Qwen3.6 Plus, which means the provider does not price it separately here — not that caching is unavailable.

How these numbers are produced
- Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
- Scores — LiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
- Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
- “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
