Gemini 4 Argon vs Gemini 4 Carbon
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.
Gemini 4 Carbon is the better model, at roughly the same price.
Gemini 4 Carbon leads by 5.8 points overall and the two list within about 10% of each other, so the cheaper-but-weaker trade-off does not apply. Price parity plus a score gap usually makes this an easy call.

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.

Gemini 4 Argon vs Gemini 4 Carbon FAQ
Which is better, Gemini 4 Argon or Gemini 4 Carbon?
Gemini 4 Carbon is the better model, at roughly the same price. Gemini 4 Carbon leads by 5.8 points overall and the two list within about 10% of each other, so the cheaper-but-weaker trade-off does not apply. Price parity plus a score gap usually makes this an easy call.
Is Gemini 4 Argon cheaper than Gemini 4 Carbon?
They cost about the same. Both land near $4.00 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.
Gemini 4 Argon vs Gemini 4 Carbon: which scores higher on benchmarks?
Gemini 4 Argon scores 77.7 and Gemini 4 Carbon scores 83.5 overall on LiveBench, the weighted mean of its seven categories. That is a 5.8-point lead for Gemini 4 Carbon. 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, Gemini 4 Argon or Gemini 4 Carbon?
They are close. Gemini 4 Argon costs $0.0182 per point of overall capability and Gemini 4 Carbon costs $0.0202, a difference small enough that workload shape will matter more than the rate.
Does Gemini 4 Argon or Gemini 4 Carbon have a bigger context window?
They are effectively the same — 1.0M for Gemini 4 Argon and 1.0M for Gemini 4 Carbon.
Do Gemini 4 Argon and Gemini 4 Carbon support prompt caching?
Both publish a cached-input rate: $0.100 per million for Gemini 4 Argon and $0.100 for Gemini 4 Carbon, against full input rates of $2.00 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 2026-11-06, 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.
