What DeepSeek V4 Pro costs at your volume

Calculated at $0.66 input / $1.98 output per 1M tokens, 3.0× apart on this model, assuming a 5:1 input-to-output ratio. That ratio is the single largest source of error in this table: resend-heavy workloads drift well past it, and at 3.0× the correction is not linear. The cost calculator takes the actual figures.

When DeepSeek V4 Pro is the right call

At $0.66 in and $1.98 out per million tokens, DeepSeek V4 Pro lands where most production deployments actually live — cheap enough to leave running, expensive enough that you still look at the bill. The 3.0× output multiple is conventional, so standard cost intuition holds: output dominates, context matters, neither is pathological.

It is not the answer at either end. Bulk classification finds identical results several times cheaper, and the hardest reasoning problems reward moving up rather than staying here. Everything in between is this model's ground.

Where DeepSeek V4 Pro sits in the index

DeepSeek V4 Pro is 135 of 226 on input rate and 120 of 226 on output rate. A gap of 15 places, because on this model the output rate is 3.0× the input rate, flatter than the index median of 4.0× An output-heavy workload therefore leaves it almost where it started, which is why the cheapest model per input token is routinely not the cheapest per task. Percentile is the share of the 226 models in this index that cost more than DeepSeek V4 Pro.

On an agent mix the lowest blended rate in the same index is Gemma2 9B It at $0.01 per 1M tokens, about 165.0× less than this model at the same ratio. Across the whole index, sorting by input price alone moves a model by as much as 74 places; on DeepSeek V4 Pro specifically the shift is 15 — which is what the re-ranked index exists to show.

DeepSeek V4 Pro is 135 of 226 across every model in the index; the comparison that usually settles a choice is DeepSeek's own lineup further down.

DeepSeek V4 Pro among DeepSeek's 4 models

DeepSeek V4 Pro is the most expensive of DeepSeek's 4 models in this index at $0.66 per 1M input tokens. The range inside that group runs from DeepSeek V4.1 Flash at $0.15 to DeepSeek V4 Pro at $0.66 (a spread of 4×, and this is the top of it) DeepSeek V4.1 Flash does the same job at 1/4 of the input rate.

On input rate alone, dropping to DeepSeek R1 cuts it by 56%. Both measured at 2026-11-01, the same check as every other rate on this page.

Calling DeepSeek V4 Pro

The identifier you send is deepseek-v4-pro-0813. Copy it exactly, because a mismatch returns a model error rather than a connection error, which sends most people to debug the wrong thing. Everything else is a base URL argument (DeepSeek V4 Pro's own SDKs work unchanged).

from openai import OpenAI

client = OpenAI(base_url="https://aicomp.ai/v1", api_key="sk-...")

resp = client.chat.completions.create(
    model="deepseek-v4-pro-0813",
    messages=[
        {"role": "system", "content": "Answer in one short paragraph."},
        {"role": "user", "content": "Explain what changed in this release."},
    ],
    max_tokens=300,
)

# prompt_tokens / completion_tokens 是真实账单的唯一依据 —— 记下来，别猜
print(resp.usage.prompt_tokens, resp.usage.completion_tokens)

Log the usage object on every call, not just while you are optimising. On DeepSeek V4 Pro output costs 3.0× what input costs, so the same monthly token count bills very differently depending on how much of it comes back as output — measure your own split before extrapolating from the headline input rate, because rates move with vendor promotions.

Setting it up

Pointing an existing integration at DeepSeek V4 Pro is a base URL change, not a rewrite. Pick your tool:

• Claude Code — set the base URL via environment variables
• Cursor — override the API endpoint in settings
• OpenAI / Anthropic SDK — one base_url argument
• Python, sync, streaming and async examples
• Cutting the bill — eight levers ranked by effect

What different usage shapes cost on DeepSeek V4 Pro

A monthly token budget does not convert cleanly into a monthly invoice, and DeepSeek V4 Pro is an ordinary case rather than an extreme one: output is priced at 3.0× input, below the median of 4.0× across the 226 models in our index. Everything follows from that one number At 5:1 it is manageable, at 1:1 the same token count costs half as much. Below are five shapes real DeepSeek V4 Pro deployments fall into, each costing it out at the split it actually produces.

The cheapest comparison is GPT-5 nano at $0.025 / $0.2 per 1M — 11.7× cheaper than DeepSeek V4 Pro on a blended rate. Treat it as a rate floor, not a recommendation: it says nothing about whether GPT-5 nano can do the work you need DeepSeek V4 Pro for.

Read the table as a sanity check rather than a forecast. If your own output share sits anywhere near 3%, everything above is priced almost entirely at DeepSeek V4 Pro's $0.66 input rate; at 40% the $1.98 output rate has taken the larger half. Nobody's split is exactly the one you assumed when you picked the model, which is why the calculator asks for it before quoting anything.
