Magnum v4 72B vs Gemini 3.5 Flash FAQ

Which is better, Magnum v4 72B or Gemini 3.5 Flash?

Magnum v4 72B and Gemini 3.5 Flash are priced within ~10% of each other. Magnum v4 72B 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.

Is Magnum v4 72B cheaper than Gemini 3.5 Flash?

They cost about the same. Both land near $3.13 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.

Does Magnum v4 72B or Gemini 3.5 Flash have a bigger context window?

Gemini 3.5 Flash has the larger context window: 33K for Magnum v4 72B against 1.0M for Gemini 3.5 Flash. 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 Magnum v4 72B and Gemini 3.5 Flash support prompt caching?

Gemini 3.5 Flash publishes a cached-input rate of $0.150 per million tokens against a full input rate of $1.50. The catalogue lists no separate cached rate for Magnum v4 72B, 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.
