Frequently asked questions

Is OpenAI or DeepSeek cheaper?

DeepSeek has the cheaper entry point at $0.10/1M output (DeepSeek R1 0528 Qwen3 8B — $0.10/1M output). Provider-wide, OpenAI averages $30.78/1M output against $0.863/1M for DeepSeek. Which is cheaper for you depends on which model tier your workload actually needs.

How much do OpenAI and DeepSeek cost per 1M tokens?

OpenAI starts at $0.140 per 1M output tokens (gpt-oss-20b), with its current flagship Daybreak Red at $75.00. DeepSeek starts at $0.100 (DeepSeek R1 0528 Qwen3 8B), with DeepSeek R1 at $2.19. Input tokens cost less than output on both.

Which has the larger context window, OpenAI or DeepSeek?

OpenAI — gpt-5.4 (>272K context length) — 2.0M input tokens. For comparison, OpenAI's largest is 2.0M tokens (gpt-5.4 (>272K context length)) and DeepSeek's is 1.0M tokens (DeepSeek Flash).

Which has more reasoning models, OpenAI or DeepSeek?

OpenAI lists 18 reasoning models and DeepSeek lists 4. Reasoning models bill their internal thinking as output tokens, so a reasoning call costs several times a standard completion of the same visible length — compare them on total tokens billed, not headline rate.

Can I self-host OpenAI or DeepSeek models?

DeepSeek publishes open-weight models you can run on your own hardware; OpenAI does not. Self-hosting swaps per-token pricing for GPU-hour cost, which usually only wins above sustained high utilisation — below that, hosted inference is cheaper.

Should I switch from OpenAI to DeepSeek to save money?

Only if the cheaper model still meets your quality bar. Token price is one input; the ones that decide your bill are prompt size, response length, retries and how much conversation history you resend each turn. Model the switch against your real traffic before committing. Prices here are current as of October 12, 2026.
