DeepSeek V4 Pro 0813 vs GPT-5.4 Mini

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.

OpenRouter + LiveBenchAll comparisonsFull leaderboard

DeepSeek V4 Pro 0813 is the better model, at roughly the same price.

DeepSeek V4 Pro 0813 leads by 11.1 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. DeepSeek V4 Pro 0813 also leads on measured cost per point of capability, at $0.0241 per point.

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.

DeepSeek V4 Pro 0813 vs GPT-5.4 Mini FAQ

Which is better, DeepSeek V4 Pro 0813 or GPT-5.4 Mini?

DeepSeek V4 Pro 0813 is the better model, at roughly the same price. DeepSeek V4 Pro 0813 leads by 11.1 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. DeepSeek V4 Pro 0813 also leads on measured cost per point of capability, at $0.0241 per point.

Is DeepSeek V4 Pro 0813 cheaper than GPT-5.4 Mini?

They cost about the same. Both land near $1.78 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.

DeepSeek V4 Pro 0813 vs GPT-5.4 Mini: which scores higher on benchmarks?

DeepSeek V4 Pro 0813 scores 77.4 and GPT-5.4 Mini scores 66.4 overall on LiveBench, the mean of its seven categories. That is a 11.1-point lead for DeepSeek V4 Pro 0813. 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, DeepSeek V4 Pro 0813 or GPT-5.4 Mini?

DeepSeek V4 Pro 0813. 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. DeepSeek V4 Pro 0813 works out at $0.0241 per point and GPT-5.4 Mini at $0.1871.

Does DeepSeek V4 Pro 0813 or GPT-5.4 Mini have a bigger context window?

DeepSeek V4 Pro 0813 has the larger context window: 1.0M for DeepSeek V4 Pro 0813 against 400K for GPT-5.4 Mini. 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 DeepSeek V4 Pro 0813 and GPT-5.4 Mini support prompt caching?

Both publish a cached-input rate: $0.040 per million for DeepSeek V4 Pro 0813 and $0.075 for GPT-5.4 Mini, against full input rates of $1.19 and $0.750. 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.
  • ScoresLiveBench 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.
