GPT-6.1 Terra vs Palmyra X5
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 and Palmyra X5 are priced within ~10% of each other.
Palmyra X5 does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only. A missing score means "not evaluated", not "worse" — the right way to separate these two is an eval on your own workload.

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, Palmyra X5 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 Palmyra X5 FAQ
Which is better, GPT-6.1 Terra or Palmyra X5?
GPT-6.1 Terra and Palmyra X5 are priced within ~10% of each other. Palmyra X5 does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only.

Is GPT-6.1 Terra cheaper than Palmyra X5?
They cost about the same. Both land near $2.00 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.

They are effectively the same — 1.1M for GPT-6.1 Terra and 1.0M for Palmyra X5.
Do GPT-6.1 Terra and Palmyra X5 support prompt caching?
GPT-6.1 Terra publishes a cached-input rate of $0.050 per million tokens against a full input rate of $1.00. The catalogue lists no separate cached rate for Palmyra X5, 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 2026-10-25, 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.
Published benchmarks rank models on someone else's tasks. Before committing, see LLM & agent evaluation for building an eval on your own.
