Where the money is

If 60% of your traffic is simple enough for Mistral Large 4, routing it there instead of DeepSeek V4 Pro saves about $324/month.

Caching half your input on DeepSeek V4 Pro (a shared system prompt or document) would cut about $383/month.

You're looking at $609–$1,148/month.

Most AI products I audit can cut that 30–60% with routing, caching and shorter prompts.

How the math works

Every provider bills input tokens (your prompt, system prompt and retrieved documents) and output tokens (the reply) separately, per million. Output is usually 4–5× the input price, so chatty apps are output-heavy and RAG apps are input-heavy.

cost per request = (fresh_in × input_price
+ cached_in × cached_price
+ out × output_price) / 1,000,000
× (1 − batched_share × batch_discount)
monthly = cost per request × requests per day × 30

Two adjustments are applied automatically. Introductory prices (currently on some Gemini models) are used until their end date. Long-prompt surcharges kick in when your average input crosses the provider's threshold: 272K tokens on current OpenAI models, 100K on Claude Haiku 5.5.

Not modelled: cache-write premiums, priority or fast tiers, regional surcharges, image and audio tokens, and reasoning tokens a model spends before answering (they bill as output, so add them to your output estimate if you use extended thinking).

DeepSeek V4 Pro questions

How much does DeepSeek V4 Pro cost per 1M tokens?
DeepSeek V4 Pro costs $1.32 per 1M input tokens and $3.96 per 1M output tokens, with cached input at $0.044 per 1M. There is no batch tier.
Is DeepSeek V4 Pro cheaper than Gemini 3.8 Flash?
For a typical request of 2,000 input and 300 output tokens, Gemini 3.8 Flash is about 1.5× cheaper ($0.00383 vs $0.00263 per call for DeepSeek V4 Pro and Gemini 3.8 Flash). Price is only half the decision; test both on your own prompts.
What is prompt caching and should I use it?
When the start of your prompt (system prompt, tool definitions, a long document) repeats across requests, providers can serve it from cache at a fraction of the input price, often 90–99% off. If your requests share a large fixed prefix, caching is usually the single biggest saving available. Put the stable content first and the variable content last.
Why does my real bill differ from this estimate?
Usually because of tokens you are not counting: reasoning or thinking tokens (billed as output), retries, tool-call round trips, and cache-write premiums. Compare the estimate against the usage page in your provider console for a week and adjust the averages.
