GPT-6 Astra vs Jev Router
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 Astra and Jev Router are priced within ~10% of each other.
Jev Router 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 Astra on top, Jev Router 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.

Which is better, GPT-6 Astra or Jev Router?
GPT-6 Astra and Jev Router are priced within ~10% of each other. Jev Router does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only.

Does GPT-6 Astra or Jev Router have a bigger context window?
They are effectively the same — 1.1M for GPT-6 Astra and 1M for Jev Router.
Do GPT-6 Astra and Jev Router support prompt caching?
GPT-6 Astra publishes a cached-input rate of $1.00 per million tokens against a full input rate of $10.00. The catalogue lists no separate cached rate for Jev Router, 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.
