Is Hermes 3 405B Instruct cheaper than Nemotron 3 Ultra?

They cost about the same. Both land near $1.00 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.

Does Hermes 3 405B Instruct or Nemotron 3 Ultra have a bigger context window?

Nemotron 3 Ultra has the larger context window: 131K for Hermes 3 405B Instruct against 262K for Nemotron 3 Ultra. Note that a window you can fill is not a window you should fill — retrieval quality usually degrades well before the limit, and you pay for every token you put in it.

Do Hermes 3 405B Instruct and Nemotron 3 Ultra support prompt caching?

Nemotron 3 Ultra publishes a cached-input rate of $0.120 per million tokens against a full input rate of $0.600. The catalogue lists no separate cached rate for Hermes 3 405B Instruct, 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.
  • ScoresLiveBench 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.

Published benchmarks rank models on someone else's tasks. Before committing, see LLM & agent evaluation for building an eval on your own.
