DeepSeek V4 Pro 0423 vs GPT-5.2
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-5.2 scores higher, DeepSeek V4 Pro 0423 costs less — it depends on your workload.
GPT-5.2 is ahead by 3.1 points overall, and DeepSeek V4 Pro 0423 lists 7.2× cheaper per blended million tokens. Whether 3.1 points is worth that depends on how much a wrong answer costs you. DeepSeek V4 Pro 0423 also leads on measured cost per point of capability, at $0.0261 per point.

Benchmarks by category
An overall score averages away the thing you probably care about. These are the seven LiveBench categories scored separately — DeepSeek V4 Pro 0423 on top, GPT-5.2 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.

DeepSeek V4 Pro 0423 vs GPT-5.2 FAQ
Which is better, DeepSeek V4 Pro 0423 or GPT-5.2?
GPT-5.2 scores higher, DeepSeek V4 Pro 0423 costs less — it depends on your workload. GPT-5.2 is ahead by 3.1 points overall, and DeepSeek V4 Pro 0423 lists 7.2× cheaper per blended million tokens. Whether 3.1 points is worth that depends on how much a wrong answer costs you. DeepSeek V4 Pro 0423 also leads on measured cost per point of capability, at $0.0261 per point.
Is DeepSeek V4 Pro 0423 cheaper than GPT-5.2?
DeepSeek V4 Pro 0423 is cheaper. On a 3:1 input:output blend, DeepSeek V4 Pro 0423 lists at $0.665 per million tokens and GPT-5.2 at $4.81 — DeepSeek V4 Pro 0423 is 7.2× cheaper. Input and output are priced separately — DeepSeek V4 Pro 0423 charges $0.532 in and $1.06 out, GPT-5.2 charges $1.75 and $14.00 — so the model that looks cheaper flips depending on how output-heavy your workload is.
DeepSeek V4 Pro 0423 vs GPT-5.2: which scores higher on benchmarks?
DeepSeek V4 Pro 0423 scores 71.6 and GPT-5.2 scores 74.6 overall on LiveBench, the mean of its seven categories. That is a 3.1-point lead for GPT-5.2. 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 0423 or GPT-5.2?
DeepSeek V4 Pro 0423. 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 0423 works out at $0.0261 per point and GPT-5.2 at $0.1289.
Does DeepSeek V4 Pro 0423 or GPT-5.2 have a bigger context window?
DeepSeek V4 Pro 0423 has the larger context window: 1.0M for DeepSeek V4 Pro 0423 against 400K for GPT-5.2. 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 0423 and GPT-5.2 support prompt caching?
Both publish a cached-input rate: $0.044 per million for DeepSeek V4 Pro 0423 and $0.175 for GPT-5.2, against full input rates of $0.532 and $1.75. 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 2026-06-25, 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.
