❯ DeepSeek Backend Notice Flags Major API Price Hike, Hitting an Inflection Point in the Low-Price Era of Chinese Large Models

ANNOUNCEMENTDeepSeek has posted a notice in its user console saying it will significantly raise API pricing across the board in the near future, without disclosing the exact scale or effective date — the company said only that an official notice will follow. The company that drove domestic large-model prices to rock bottom is, for the first time, voluntarily pulling prices back — its V4-Flash output price was previously as low as 2 yuan per million tokens, and cache-hit input cost as little as 0.02 yuan per million tokens.

CAUSEThe price hike is not a sudden whim. What the low prices bought was call volume too heavy to sustain: weekly call volume for a single model once exceeded tens of trillions of tokens and repeatedly ranked No. 1 globally — at the cost of frequent timeouts and lag on API endpoints during weekday peak hours. In mid-July, DeepSeek had already tested the waters, rolling out time-of-day pricing — prices doubled during the two weekday peak windows of 9:00–12:00 and 14:00–18:00, while off-peak hours and weekends stayed unchanged. This time, it is swapping the time-based patch for an overall price adjustment. Researcher teortaxesTex argued on X that if DeepSeek also unlocks vision capabilities on the API at the same time, the hike would come with something worth paying for — its image understanding is already good enough, and the cache mechanism makes that part extremely cost-efficient.

FIRST HITThe first to be hit are small and mid-sized developers who use DeepSeek as their default backend: over the past year, countless applications built their cost models on the premise that “tokens are so cheap they don’t need to be counted” — and that premise is now falling apart. The pricing logic of large-model APIs is thus switching from “burning cash for scale” back to “billing by compute,” and it comes precisely at the moment when rivals like Kimi K3 and Qwen3.8-Max are pushing per-task costs even lower. The price war among Chinese large models may not be over, but the phase propped up by losses has run its course.

▪ SIGNALThe price slasher is raising prices itself — the ledger behind rock-bottom pricing no longer balances.
