GPT-5.4 Mini vs Ox Alpha
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.
Ox Alpha wins outright — it scores higher and costs less.
Ox Alpha leads by 2.9 points overall. There is no trade-off to reason about here; the only reason to pick the other is a constraint this table does not show, like an existing contract, a region, or a provider you are already on. Ox Alpha also leads on measured cost per point of capability, at $0.0000 per point.

Benchmarks by category
An overall score averages away the thing you probably care about. These are the seven LiveBench categories scored separately — GPT-5.4 Mini on top, Ox Alpha 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.

GPT-5.4 Mini vs Ox Alpha FAQ
Which is better, GPT-5.4 Mini or Ox Alpha?
Ox Alpha wins outright — it scores higher and costs less. Ox Alpha leads by 2.9 points overall. There is no trade-off to reason about here; the only reason to pick the other is a constraint this table does not show, like an existing contract, a region, or a provider you are already on. Ox Alpha also leads on measured cost per point of capability, at $0.0000 per point.
Is GPT-5.4 Mini cheaper than Ox Alpha?
Ox Alpha is cheaper. On a 3:1 input:output blend, GPT-5.4 Mini lists at $1.69 per million tokens and Ox Alpha at Free. Input and output are priced separately — GPT-5.4 Mini charges $0.750 in and $4.50 out, Ox Alpha charges Free and Free — so the model that looks cheaper flips depending on how output-heavy your workload is.
GPT-5.4 Mini vs Ox Alpha: which scores higher on benchmarks?
GPT-5.4 Mini scores 66.4 and Ox Alpha scores 69.2 overall on LiveBench, the mean of its seven categories. That is a 2.9-point lead for Ox Alpha. 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, GPT-5.4 Mini or Ox Alpha?
Ox Alpha. 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. GPT-5.4 Mini works out at $0.1871 per point and Ox Alpha at $0.0000.
Does GPT-5.4 Mini or Ox Alpha have a bigger context window?
Ox Alpha has the larger context window: 400K for GPT-5.4 Mini against 1.0M for Ox Alpha. 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 GPT-5.4 Mini and Ox Alpha support prompt caching?
GPT-5.4 Mini publishes a cached-input rate of $0.075 per million tokens against a full input rate of $0.750. The catalogue lists no separate cached rate for Ox Alpha, 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 2026-06-25, 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.
