GPT-6.1 Terra vs MiMo-V2.6-Pro
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.
GPT-6.1 Terra scores higher, MiMo-V2.6-Pro costs less — it depends on your workload.
GPT-6.1 Terra is ahead by 9.3 points overall, and MiMo-V2.6-Pro lists 3.7× cheaper per blended million tokens. Whether 9.3 points is worth that depends on how much a wrong answer costs you. MiMo-V2.6-Pro also leads on measured cost per point of capability, at $0.0018 per point.

Benchmarks by category
An overall score averages away the thing you probably care about. These are the seven LiveBench categories scored separately — GPT-6.1 Terra on top, MiMo-V2.6-Pro 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.

GPT-6.1 Terra vs MiMo-V2.6-Pro FAQ
Which is better, GPT-6.1 Terra or MiMo-V2.6-Pro?
GPT-6.1 Terra scores higher, MiMo-V2.6-Pro costs less — it depends on your workload. GPT-6.1 Terra is ahead by 9.3 points overall, and MiMo-V2.6-Pro lists 3.7× cheaper per blended million tokens. Whether 9.3 points is worth that depends on how much a wrong answer costs you. MiMo-V2.6-Pro also leads on measured cost per point of capability, at $0.0018 per point.
Is GPT-6.1 Terra cheaper than MiMo-V2.6-Pro?
MiMo-V2.6-Pro is cheaper. On a 3:1 input:output blend, GPT-6.1 Terra lists at $2.00 per million tokens and MiMo-V2.6-Pro at $0.544 — MiMo-V2.6-Pro is 3.7× cheaper. Input and output are priced separately — GPT-6.1 Terra charges $1.00 in and $5.00 out, MiMo-V2.6-Pro charges $0.435 and $0.870 — so the model that looks cheaper flips depending on how output-heavy your workload is.
GPT-6.1 Terra vs MiMo-V2.6-Pro: which scores higher on benchmarks?
GPT-6.1 Terra scores 77.8 and MiMo-V2.6-Pro scores 68.5 overall on LiveBench, the weighted mean of its seven categories. That is a 9.3-point lead for GPT-6.1 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-6.1 Terra or MiMo-V2.6-Pro?
MiMo-V2.6-Pro. 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-6.1 Terra works out at $0.0067 per point and MiMo-V2.6-Pro at $0.0018.
Does GPT-6.1 Terra or MiMo-V2.6-Pro have a bigger context window?
They are effectively the same — 1.1M for GPT-6.1 Terra and 1.1M for MiMo-V2.6-Pro.
Do GPT-6.1 Terra and MiMo-V2.6-Pro support prompt caching?
Both publish a cached-input rate: $0.050 per million for GPT-6.1 Terra and $0.0036 for MiMo-V2.6-Pro, against full input rates of $1.00 and $0.435. 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.
