Muse Wonder vs GPT-5.6 Terra
Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.
Muse Wonder scores higher, GPT-5.6 Terra costs less — it depends on your workload.
Muse Wonder is ahead by 6.4 points overall, and GPT-5.6 Terra lists 1.8× cheaper per blended million tokens. Whether 6.4 points is worth that depends on how much a wrong answer costs you.

Benchmarks by category
An overall score averages away the thing you probably care about. These are the seven LiveBench categories scored separately — Muse Wonder on top, GPT-5.6 Terra below, both out of 100.
What each one costs to run
Per-token prices are hard to feel. These are monthly list costs for both models across five workload shapes, using each provider's published cached-input rate where there is one.

Muse Wonder vs GPT-5.6 Terra FAQ
Which is better, Muse Wonder or GPT-5.6 Terra?
Muse Wonder scores higher, GPT-5.6 Terra costs less — it depends on your workload. Muse Wonder is ahead by 6.4 points overall, and GPT-5.6 Terra lists 1.8× cheaper per blended million tokens. Whether 6.4 points is worth that depends on how much a wrong answer costs you.
Is Muse Wonder cheaper than GPT-5.6 Terra?
GPT-5.6 Terra is cheaper. On a 3:1 input:output blend, Muse Wonder lists at $8.00 per million tokens and GPT-5.6 Terra at $4.50 — GPT-5.6 Terra is 1.8× cheaper. Input and output are priced separately — Muse Wonder charges $4.00 in and $20.00 out, GPT-5.6 Terra charges $2.00 and $12.00 — so the model that looks cheaper flips depending on how output-heavy your workload is.
Muse Wonder vs GPT-5.6 Terra: which scores higher on benchmarks?
Muse Wonder scores 74.2 and GPT-5.6 Terra scores 67.8 overall on LiveBench, the weighted mean of its seven categories. That is a 6.4-point lead for Muse Wonder. 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, Muse Wonder or GPT-5.6 Terra?
They are close. Muse Wonder costs $0.0201 per point of overall capability and GPT-5.6 Terra costs $0.0196, a difference small enough that workload shape will matter more than the rate.
Does Muse Wonder or GPT-5.6 Terra have a bigger context window?
They are effectively the same — 1.0M for Muse Wonder and 1.1M for GPT-5.6 Terra.
Do Muse Wonder and GPT-5.6 Terra support prompt caching?
Both publish a cached-input rate: $0.200 per million for Muse Wonder and $0.200 for GPT-5.6 Terra, against full input rates of $4.00 and $2.00. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

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 2026-10-25, 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.
