> V4.1-Flash and V4-Pro, priced per 1M tokens in peak/off-peak bands

The official API pricing page opened on 2026-10-12 (api-docs.deepseek.com/quick_start/pricing) lists only two models: deepseek-flash, which maps to DeepSeek-V4.1-Flash, and deepseek-v4-pro, which maps to DeepSeek-V4-Pro-0813. Both expose OpenAI and Anthropic base URL formats, a 1M context, up to 384K maximum output, and both non-thinking and thinking (default) modes. Prices are per 1M tokens and split into peak and off-peak: for deepseek-flash, input with a cache hit is off-peak 0.003 and peak 0.006 USD, input with a cache miss off-peak 0.15 and peak 0.3, and output off-peak 0.6 and peak 1.2; deepseek-v4-pro is 0.022 / 0.044, 0.66 / 1.32, and 1.98 / 3.96 USD in the same order. A page footnote says off-peak rates are half of peak, and that peak hours are 01:00-04:00 and 06:00-10:00 UTC Monday through Friday, with all other hours and full Chinese public holidays counting as off-peak. The same footnote set says the legacy names deepseek-v4-flash and deepseek-v4-flash-vision-exp are still accepted but the corresponding models are retired, with requests served by DeepSeek-V4.1-Flash and billed at the Flash price. Concurrency limits are 2500 for flash and 500 for v4-pro. Charges are token count times price, deducted from the topped-up or granted balance with the granted balance used first; the page says prices may change and advises topping up for actual usage and rechecking regularly. In the feature rows, vision is ticked only for flash and v4-pro is marked Not supported. The page states no region and says nothing about open weights or commercial licence scope. This is not a hands-on test.

## When to pick it

Choose the DeepSeek API when per-million-token rates have to be costed out for a coding or reasoning workload and you can live with two rate bands, peak and off-peak, plus concurrency caps of 2500 and 500.

## When to skip it

The page says deepseek-v4-flash and deepseek-v4-flash-vision-exp are retired and now served by DeepSeek-V4.1-Flash at the Flash price, so integrations with a model name or version pinned in code have to change. Vision is flash-only and v4-pro is marked Not supported; if you want open weights to self-host, the closer record in this directory is Qwen, and if you need one long document read rather than a token-billed API, the closer record is Kimi. The page states no region and no commercial licence scope (unverified).

### How do I decide if DeepSeek fits my team?

Judge DeepSeek on three points: whether the pricing model (currently Freemium) fits the budget, that platform coverage was not checked item by item on this source page, and whether the core capabilities (deepseek-flash (V4.1-Flash) and deepseek-v4-pro, OpenAI and Anthropic base URL formats, 1M context, up to 384K maximum output) match the workflow.
