Reasoning levels

Which level to choose

DeepSeek names these settings reasoning_effort. Price per token is the same at every level. Higher levels usually use more output tokens. api-docs.deepseek.com (opens in a new tab)

Our rule of thumb: Simple or speed-critical work: low. Standard work: the lab's default. Complex work: high. Use xhigh or max only when your own tests show a gain, as OpenAI and Anthropic both advise. developers.openai.com (opens in a new tab)platform.claude.com (opens in a new tab)

DeepSeek China

DeepSeek ships a faster V4.1-Flash update, with open weights

DeepSeek says V4.1-Flash-1017 finishes tasks faster with shorter answers at unchanged API prices, from $0.15 in and $0.60 out per 1M tokens off-peak. The weights are on Hugging Face under the MIT licence. Benchmark gains are DeepSeek's own figures.

DeepSeek China

DeepSeek opens its own search engine to developers at $0.75 per 1,000 calls

DeepSeek's Search and Fetch APIs give agents web results and pages as text. Calls made through its own harness, Claude Code or Codex were free until billing began on 1 November 2026, Beijing time. More agent traffic means more inference load on DeepSeek's capacity.
