DeepSeek V4 Pro 0813 vs GPT-5.4 Nano

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 scores higher, GPT-5.4 Nano costs less — it depends on your workload.

DeepSeek V4 Pro 0813 is ahead by 7.9 points overall, and GPT-5.4 Nano lists 3.9× cheaper per blended million tokens. Whether 7.9 points is worth that depends on how much a wrong answer costs you. The two cost measures disagree here, which is worth knowing: GPT-5.4 Nano has the lower sticker price, but DeepSeek V4 Pro 0813 earns each point of capability for less — $0.0241 against $0.0500 — because per-token rates do not predict how many tokens a model actually spends on a task.

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 Nano FAQ

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

DeepSeek V4 Pro 0813 scores higher, GPT-5.4 Nano costs less — it depends on your workload. DeepSeek V4 Pro 0813 is ahead by 7.9 points overall, and GPT-5.4 Nano lists 3.9× cheaper per blended million tokens. Whether 7.9 points is worth that depends on how much a wrong answer costs you. The two cost measures disagree here, which is worth knowing: GPT-5.4 Nano has the lower sticker price, but DeepSeek V4 Pro 0813 earns each point of capability for less — $0.0241 against $0.0500 — because per-token rates do not predict how many tokens a model actually spends on a task.

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

GPT-5.4 Nano is cheaper. On a 3:1 input:output blend, DeepSeek V4 Pro 0813 lists at $1.78 per million tokens and GPT-5.4 Nano at $0.463 — GPT-5.4 Nano is 3.9× cheaper. Input and output are priced separately — DeepSeek V4 Pro 0813 charges $1.19 in and $3.56 out, GPT-5.4 Nano charges $0.200 and $1.25 — so the model that looks cheaper flips depending on how output-heavy your workload is.

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

DeepSeek V4 Pro 0813 scores 77.4 and GPT-5.4 Nano scores 69.6 overall on LiveBench, the mean of its seven categories. That is a 7.9-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 Nano?

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 Nano at $0.0500.

Does DeepSeek V4 Pro 0813 or GPT-5.4 Nano 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 Nano. 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 Nano support prompt caching?

Both publish a cached-input rate: $0.040 per million for DeepSeek V4 Pro 0813 and $0.020 for GPT-5.4 Nano, against full input rates of $1.19 and $0.200. 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.
