DeepSeek hikes V4.1 Flash API prices up to 2400% as Harness agent platform hits 1.54M daily users

DeepSeek has repriced its flagship cheap model sharply. Per overfeed.news and silicon.co.uk:

- V4.1 Flash input went from $0.051 to $0.30 per million tokens, up 488%.

- V4.1 Flash output went from $0.567 to $1.20 per million tokens, up 112%.

- The V4.1 Flash 1017 variant's input price rose 2400% to $0.15 per million tokens.

These prices are still low by Western frontier standards. But they remove much of the order-of-magnitude gap that made DeepSeek the default for cost-sensitive bulk workloads.

The hike coincides with real scale. Harness, DeepSeek's open-source agent platform, reports 1.54 million daily active users, about 92 trillion tokens processed per day, and an ecosystem of 35,000 third-party plugins. Serving that volume needs compute that is increasingly hard for Chinese labs to obtain. This week's reports of tighter US rules on remote access to chips in Southeast Asian data centers point the same direction. The price move can be read as DeepSeek moving toward sustainable unit economics rather than subsidized growth.

The competitive picture has shifted too. Google's Gemini 4 Carbon at $4/$20 targets a different tier. Alibaba is offering Qwen4-Max preview access at as little as 10% of list price, and community GGUF builds of DeepSeek coders keep spreading for self-hosting. One r/DeepSeek thread claims an optimized V4.1-Flash build runs faster on B200 than vLLM and SGLang do on GB300, which strengthens the case for self-hosting the open weights instead of paying the API.

Developers were shocked, according to community reaction. Many say the hike undercuts DeepSeek's main selling point despite strong Harness adoption. Watch whether DeepSeek offers a subscription coding agent, a question already circulating on Reddit, and whether rivals use this moment to win migrating workloads.
