How Much Would My Monthly Token Costs Be If I Switch Entirely to DeepSeek V4?

Token usage baseline

In the past 30 days the user consumed approximately 1.8 billion tokens on Zhipu AI’s Pro plan (no weekly or monthly limits).

Cost estimation for DeepSeek V4

DeepSeek‑V4‑Flash (high‑cost‑performance / fast version)

Extreme case – 100 % input tokens, cache hit: 1 800 × 0.2 CNY = 360 CNY/month

Typical case – 100 % input, cache miss: 1 800 × 1 CNY = 1 800 CNY/month

Burn‑money case – 100 % output tokens: 1 800 × 2 CNY = 3 600 CNY/month

Balanced case – 50 % input, 50 % output, cache miss: (900 × 1 CNY) + (900 × 2 CNY) = 2 700 CNY/month

DeepSeek‑V4‑Pro (expert / high‑performance version)

Extreme case – 100 % input, cache hit: 1 800 × 1 CNY = 1 800 CNY/month

Typical case – 100 % input, cache miss: 1 800 × 12 CNY = 21 600 CNY/month

Burn‑money case – 100 % output: 1 800 × 24 CNY = 43 200 CNY/month

Balanced case – 50 % input, 50 % output, cache miss: (900 × 12 CNY) + (900 × 24 CNY) = 32 400 CNY/month

Result

All calculated monthly costs exceed the current spending on Zhipu AI, indicating that although DeepSeek V4’s per‑token price is lower, the total expense is dominated by the high token volume of existing coding workloads.

Context on pricing trends

Major AI service providers previously offered heavily discounted “coding plans” to boost IPO metrics; those promotions have ended, leaving users to bear higher prices.
