DeepSeek V4 Pro API

Flagship reasoning and coding model — flat pricing, 78% below official peak rates (¥9/¥27), with cached input at $0.028 per 1M tokens.

FlagshipBest for: Frontier reasoning and coding — the default flagship.

Why developers pick it

• Frontier reasoning and code generation at roughly open-model prices.
• No peak-hour surcharges — the same price at 10:00 and 22:00 Beijing time.
• Context caching billed at 1/10: long agent sessions and multi-turn chats get dramatically cheaper.

Code example

from openai import OpenAI

client = OpenAI(base_url="https://bridge.computeindex.net/v1", api_key="sk-bridge-YOUR_KEY")

completion = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[{"role": "user", "content": "Write a Python function that reverses a linked list."}],
    stream=True,
)
for chunk in completion:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

FAQ

Is this the same model as DeepSeek's official V4 Pro? Yes — the same model family, served through Bridge's OpenAI-compatible gateway with per-token metering.

What does flat pricing mean? No time-of-day tiers. The price on the live price table is what you pay, any hour, any day.
