Claude Haiku 4.5 also leads on measured cost per point of capability, at $0.3893 per point.
Is Claude Haiku 4.5 cheaper than Gemini 4 Argon?
Claude Haiku 4.5 is cheaper. On a 3:1 input:output blend, Claude Haiku 4.5 lists at $2.00 per million tokens and Gemini 4 Argon at $4.00 — Claude Haiku 4.5 is 2.0× cheaper. Input and output are priced separately — Claude Haiku 4.5 charges $1.00 in and $5.00 out, Gemini 4 Argon charges $2.00 and $10.00 — so the model that looks cheaper flips depending on how output-heavy your workload is.
Claude Haiku 4.5 vs Gemini 4 Argon: which scores higher on benchmarks?
Claude Haiku 4.5 scores 46.0 and Gemini 4 Argon scores 84.1 overall on LiveBench, the mean of its seven categories. That is a 38.1-point lead for Gemini 4 Argon. 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, Claude Haiku 4.5 or Gemini 4 Argon?
Claude Haiku 4.5. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. Claude Haiku 4.5 works out at $0.3893 per point and Gemini 4 Argon at $1.24.
Does Claude Haiku 4.5 or Gemini 4 Argon have a bigger context window?
Gemini 4 Argon has the larger context window: 200K for Claude Haiku 4.5 against 1.0M for Gemini 4 Argon. 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 Claude Haiku 4.5 and Gemini 4 Argon support prompt caching?
Both publish a cached-input rate: $0.100 per million for Claude Haiku 4.5 and $0.100 for Gemini 4 Argon, against full input rates of $1.00 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 2026-09-02, 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.
