Overview & Methodology

DeepSeek R1 is the breakthrough open reasoning model that matches OpenAI o1 on math, code, and logic benchmarks while costing over 95% less: $0.55 per 1M input tokens and $2.19 per 1M output tokens (cache hits drop input to $0.14/1M).

Mathematical Formulation

Single Cost = (Input / 1M × $0.55) + (Output / 1M × $2.19). Monthly = Single Cost × Daily Requests × 30.

Optimization Best Practices

1

DeepSeek R1 includes internal thinking process enclosed within `<think>` XML tags, which can be extracted or hidden in UI.

2

Cache hit pricing drops input to $0.14 per 1M tokens.

3

Use DeepSeek R1 for competitive programming, theorem proving, and automated test-driven development (TDD).

Frequently Asked Questions

Q.How does DeepSeek R1 compare in price to OpenAI o1?
A.

OpenAI o1 costs $15.00 input / $60.00 output per 1M; DeepSeek R1 costs $0.55 / $2.19 per 1M (over 95% cheaper).

Q.How are thinking tokens billed on DeepSeek R1?
A.

Internal reasoning tokens inside `<think>` are billed at the standard output rate of $2.19 per 1M tokens.

Q.How much does 10,000 requests cost on DeepSeek R1?
A.

At 1.5k input and 1.5k output tokens, 10,000 calls cost $8.25 input + $32.85 output = $41.10 total.
