Is Gemini 3.7 Flash cheaper than Hermes 4 405B?

Does Gemini 3.7 Flash or Hermes 4 405B have a bigger context window?
Gemini 3.7 Flash has the larger context window: 1.0M for Gemini 3.7 Flash against 131K for Hermes 4 405B. 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 Gemini 3.7 Flash and Hermes 4 405B support prompt caching?
Gemini 3.7 Flash publishes a cached-input rate of $0.075 per million tokens against a full input rate of $0.750. The catalogue lists no separate cached rate for Hermes 4 405B, 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.
Published benchmarks rank models on someone else's tasks. Before committing, see LLM & agent evaluation for building an eval on your own.
