GPT-5.4 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.
GPT-5.4 scores higher, Ox Alpha costs less — it depends on your workload.
GPT-5.4 is ahead by 8.7 points overall, and Ox Alpha lists at a lower blended price. Whether 8.7 points is worth that depends on how much a wrong answer costs you. 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 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 vs Ox Alpha FAQ
Which is better, GPT-5.4 or Ox Alpha?
GPT-5.4 scores higher, Ox Alpha costs less — it depends on your workload. GPT-5.4 is ahead by 8.7 points overall, and Ox Alpha lists at a lower blended price. Whether 8.7 points is worth that depends on how much a wrong answer costs you. Ox Alpha also leads on measured cost per point of capability, at $0.0000 per point.
Is GPT-5.4 cheaper than Ox Alpha?
Ox Alpha is cheaper. On a 3:1 input:output blend, GPT-5.4 lists at $5.63 per million tokens and Ox Alpha at Free. Input and output are priced separately — GPT-5.4 charges $2.50 in and $15.00 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 vs Ox Alpha: which scores higher on benchmarks?
GPT-5.4 scores 78.0 and Ox Alpha scores 69.2 overall on LiveBench, the mean of its seven categories. That is a 8.7-point lead for GPT-5.4. 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 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 works out at $0.2198 per point and Ox Alpha at $0.0000.
Does GPT-5.4 or Ox Alpha have a bigger context window?
They are effectively the same — 1.1M for GPT-5.4 and 1.0M for Ox Alpha.
Do GPT-5.4 and Ox Alpha support prompt caching?
GPT-5.4 publishes a cached-input rate of $0.250 per million tokens against a full input rate of $2.50. 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.
