Mistral Large 4 vs Sonar
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.
Mistral Large 4 and Sonar are priced within ~10% of each other.
Sonar 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 — Mistral Large 4 on top, Sonar 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.

Mistral Large 4 vs Sonar FAQ
Which is better, Mistral Large 4 or Sonar?
Mistral Large 4 and Sonar are priced within ~10% of each other. Sonar 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 Mistral Large 4 cheaper than Sonar?
They cost about the same. Both land near $1.05 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.
Does Mistral Large 4 or Sonar have a bigger context window?
Mistral Large 4 has the larger context window: 1.0M for Mistral Large 4 against 127K for Sonar. 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 Mistral Large 4 and Sonar support prompt caching?
Mistral Large 4 publishes a cached-input rate of $0.070 per million tokens against a full input rate of $0.700. The catalogue lists no separate cached rate for Sonar, 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.
