SpaceXAI: Grok 4.6 scores higher, Mistral Large 4 costs less — it depends on your workload. SpaceXAI: Grok 4.6 is ahead by 23.8 points overall, and Mistral Large 4 lists 45% cheaper per blended million tokens. Whether 23.8 points is worth that depends on how much a wrong answer costs you.

Is Mistral Large 4 cheaper than SpaceXAI: Grok 4.6?

Mistral Large 4 is cheaper. On a 3:1 input:output blend, Mistral Large 4 lists at $2.06 per million tokens and SpaceXAI: Grok 4.6 at $3.00 — Mistral Large 4 is 45% cheaper. Input and output are priced separately — Mistral Large 4 charges $1.36 in and $4.18 out, SpaceXAI: Grok 4.6 charges $2.00 and $6.00 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Mistral Large 4 vs SpaceXAI: Grok 4.6: which scores higher on benchmarks?

Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.

Which gives better value for money, Mistral Large 4 or SpaceXAI: Grok 4.6?

They are close. Mistral Large 4 costs $0.0162 per point of overall capability and SpaceXAI: Grok 4.6 costs $0.0142, a difference small enough that workload shape will matter more than the rate.

Does Mistral Large 4 or SpaceXAI: Grok 4.6 have a bigger context window?

Mistral Large 4 has the larger context window: 1.0M for Mistral Large 4 against 500K for SpaceXAI: Grok 4.6. 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 SpaceXAI: Grok 4.6 support prompt caching?

Both publish a cached-input rate: $0.140 per million for Mistral Large 4 and $0.500 for SpaceXAI: Grok 4.6, against full input rates of $1.36 and $2.00. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

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.
