What is changing in the DeepSeek API, and what it does to the cost of a call. Curated from official announcements and checked against the live API where that is possible; the in-terminal feed is ds docs changelog.

2026-08-06 · a broad price rise is comingdate tba

DeepSeek posted a notice in the platform console: all API services will be repriced “in the near term”, and the increase is expected to be substantial. Developers are advised to plan call volume and keep top-ups sized to what they will actually use. The final schedule and the new numbers are “subject to the official announcement” — and as of this page's build there is none.

The notice appears in the console rather than on the docs site, so it is easy to miss from code. It was widely reported on 2026-08-06 Beijing time.

What it changes here: nothing, yet. The cost page and ds models price from the published card of 2026-08-02 until DeepSeek publishes a new one. The ledger stores exact token counts rather than prices, deliberately — when the card changes, every historical call can be repriced under it.

announced 2026-06-29 · 2× during peak hoursdate tba

The pricing page has carried this since late June: the API will move to peak/off-peak pricing, with every billing item — input, cached input, output — costing 2× the regular price during peak hours. Off-peak, the current card stands.

The effective date is still “subject to the official announcement”. This CLI deliberately does not apply the multiplier to its estimates before that date exists — doubling every figure on a guess would be inventing data. The day it is real, the ledger's stored token counts make the switch a repricing, not a migration.

Two practical notes. First, the context cache discount is 50×; the peak multiplier is 2×. Prompt structure will still dominate your bill. Second, if batch work can move, move it — the off-peak window covers the whole European and American working day.

2026-07-31 · V4-Flash official release

The official DeepSeek-V4-Flash API entered public beta: same model name, same calling convention, re-post-trained weights with substantially stronger agent behaviour — DeepSeek's published numbers have it ahead of V4-Pro-Preview on Terminal Bench, DeepSWE and the rest of the agent suite. It natively speaks the Responses format and is explicitly adapted for Codex. The official V4-Pro release “will follow soon”.

2026-04-24 · V4 arrives, the old names leave

deepseek-v4-pro and deepseek-v4-flash became the API's two models, served through both the OpenAI and Anthropic interfaces. The legacy names deepseek-chat and deepseek-reasoner were aliased to flash for a grace period and retired on 2026-07-24 — anything still sending them gets an error, not a quiet remap.
