DeepSeek API Pricing

The Chinese lab behind the DeepSeek open-weight models. Spun out of quant hedge fund High-Flyer in 2023 by Liang Wenfeng, it shocked the industry by matching frontier reasoning quality at a fraction of the cost — and shipping the weights under an MIT license.

§ 06 / BACKGROUND

The company behind it.

www.deepseek.com →

DeepSeek was founded in July 2023 in Hangzhou by Liang Wenfeng, who also co-founded and runs the quantitative hedge fund High-Flyer (started in 2015–2016). DeepSeek is owned and funded by High-Flyer rather than by external venture capital — an unusual structure that let it train large models on a GPU cluster the fund had already built for trading.

The lab's signature is compute efficiency. Its mixture-of-experts (MoE) training recipes delivered frontier-class quality at a small fraction of the budgets reported by US labs. Liang has reportedly held a controlling personal stake (~84% as of 2024), and the team is famously lean — on the order of ~150 people, with many hired straight out of university.

DeepSeek's breakout moment came with V3 (December 2024) and then R1 (January 2025): R1 matched OpenAI o1-class reasoning at roughly 1/27 the price, the consumer app briefly topped the US App Store, and the release triggered a sharp sell-off in AI hardware stocks. In April 2026 the lab shipped the V4 family — a 1.6T-parameter MoE (V4 Pro) and a 284B MoE (V4 Flash), both with 1M-token context and MIT-licensed open weights.

Pricing is the headline, and since August 16, 2026 it depends on the hour: V4 Pro runs at $1.32/$3.96 per M at peak and $0.66/$1.98 off-peak. The old flat $0.435/$0.87 was a 75% launch promo that was supposed to revert to $1.74/$3.48 on May 31, 2026 but never did — and V4 Flash at $0.44/$1.32 peak, $0.22/$0.66 off-peak — still well below frontier US models, with cache-hit input at about 1/31 of a miss.

The trade-offs are real: the lab was text-only until August 2026 and is barely past it — the one model that reads images, V4 Flash Vision, ships under an experimental id, and nothing here handles audio. The company is China-based with data stored in China by default, and US export-control and procurement-policy questions apply. The MIT weights are the escape hatch — teams that need US/EU residency can self-host. Versus OpenAI and Anthropic, DeepSeek trades multimodal breadth and Western data governance for radically lower cost and full open weights.

Frequently asked.

Practical questions about DeepSeek pricing, open weights, and data residency.

Q · 01 Which DeepSeek model should I start with? +
For most workloads: DeepSeek V4.1 Flash ($0.30/$1.20 peak, $0.15/$0.60 off-peak), which replaced V4 Flash on September 10, 2026 and covers non-thinking, thinking and image input on one card. Call it as deepseek-flash — the version is not in the API id. Step up to V4 Pro ($1.32/$3.96 peak, $0.66/$1.98 off-peak) for the hardest reasoning; it is text-only. Both ship a 1M-token context. See the use case picker above.
Q · 02 How much cheaper is DeepSeek than OpenAI or Anthropic? +
On input, V4 Pro is roughly 3.8× cheaper than GPT-5.5 at peak ($1.32 vs $5) and ~7.6× cheaper on output ($3.96 vs $30). Off-peak, which is 17 hours of every weekday and all weekend, both gaps double. With cache-hit input at $0.044/M the gap widens further still. The text-only caveat has now lapsed on the cheap tier: V4.1 Flash reads images natively on the same card as its text traffic, at up to 1024 tokens per image, and the experimental vision endpoint it replaced was withdrawn the same day. It is still narrower than what Google or OpenAI accept — no audio, no video — and V4 Pro remains text-only.
Q · 03 Is there an off-peak discount? +
Yes — and it is the whole billing model now, not a discount bolted on top. Since 16:00 UTC on August 16, 2026 DeepSeek charges a peak rate during 01:00-04:00 and 06:00-10:00 UTC, Monday to Friday, and exactly half that in every other hour, weekends included. So off-peak covers 17 hours of a weekday and all of Saturday and Sunday. We store the peak figures because DeepSeek describes off-peak as "half the peak rates" — the peak card is the list price. Anything that can be scheduled overnight or at the weekend costs half, and as of the September 2026 re-read the footnote adds that Chinese public holidays are off-peak in full. Re-verified on the vendor page September 19, 2026.
Q · 04 Are DeepSeek models open-weight? +
Yes. V4 Pro and V4.1 Flash weights are MIT-licensed on Hugging Face — fully self-hostable, commercially usable, with no per-token fee. V4.1 Flash is a 552B backbone that activates 8B parameters per token on prefill and 16B on decode, so the self-hosting bill tracks the active count rather than the headline one. This is what lets teams run DeepSeek outside China for data-residency reasons.
Q · 05 Where is my data stored, and is that a problem? +
Using the direct DeepSeek API, data is processed and stored in China by default, which is a blocker for many EU/US compliance and procurement teams. The workaround is to self-host the MIT weights on your own US/EU cloud, or use a Western third-party host. US export-control and policy questions also apply.
Q · 06 Did the 75% V4 Pro promo ever end? +
No. DeepSeek announced the promo would expire on May 31, 2026, reverting V4 Pro to $1.74/M input and $3.48/M output. That date passed without a reprice: we have re-verified the pricing page repeatedly since. On August 16, 2026 DeepSeek replaced the flat card with peak/off-peak billing at $1.32/$3.96 and $0.66/$1.98. We treat it as the standard rate rather than a promo, and re-check the page on every pass over DeepSeek's card — the date of the last one is in the byline below.
Q · 07 How does DeepSeek compare to Qwen and Mistral? +
Qwen (Alibaba) is the closest Chinese peer with broader multimodal and multilingual coverage; Mistral is the EU open-weight peer with GDPR-native residency. DeepSeek's edge is the lowest cost-per-token at frontier reasoning quality, with the same China-data caveat as Qwen.
