If you’re running AI agents at any kind of scale, you need to know about this right now. DeepSeek just cut prices on its newest frontier model by 75% — and slashed cache-hit costs across its entire API to one-tenth of previous rates. The discount expires May 5, 2026.

The Numbers

DeepSeek V4-Pro is the company’s latest flagship — a 1.6 trillion parameter Mixture-of-Experts (MoE) model. Starting April 27, 2026:

  • V4-Pro API pricing: 75% off until May 5, 2026 at 15:59 UTC
  • Cache-hit pricing: 1/10th of previous rates across the entire DeepSeek API suite, effective immediately (not time-limited)
  • At discounted pricing, V4-Pro is approximately 20x cheaper than comparable OpenAI and Anthropic models
  • Even at full price, V4-Pro undercuts GPT-5.5, Claude Opus 4.7, and Gemini 3.1 Pro on per-token costs

This isn’t a theoretical savings number. For teams running agents in production — doing thousands of API calls per day with heavy context reuse — the cache-hit reduction alone could cut monthly API costs by 50–70%.

DeepSeek confirmed the discount in a post on X from their official @deepseek_ai account and updated their official API pricing documentation at api-docs.deepseek.com.

Why DeepSeek Is Doing This

DeepSeek’s aggressive pricing is part of a deliberate strategic play that began with the R1 release in January 2025, when the company shocked the AI industry by releasing a model competitive with GPT-4 at a fraction of the cost.

V4-Pro extends that strategy. The 75% discount is promotional — designed to drive adoption, fill inference capacity, and get engineering teams switched over before May 5. The permanent cache-hit reduction is more structural: it makes DeepSeek dramatically more attractive for applications with heavy prompt reuse, which describes most production agent workloads.

The Next Web notes that the timing is pointed: the Trump administration has accused Chinese AI firms of distilling American AI models at scale. DeepSeek’s response has essentially been to compete on price, availability, and capability transparency — publishing technical reports, releasing weights, and pricing aggressively.

Who Should Act Before May 5

High-urgency users:

  • Teams running inference on long-context tasks (legal review, code analysis, document processing) — cache savings are largest here
  • Developers prototyping new agent workflows who want to test a frontier-class model cheaply before committing to architecture decisions
  • Anyone currently paying OpenAI or Anthropic API bills above $500/month — the math warrants a serious look

Lower urgency:

  • Teams with hard requirements for US-based inference infrastructure (V4-Pro runs on DeepSeek’s own servers, likely China-based)
  • Organizations with data residency requirements that rule out DeepSeek
  • Workflows that depend on OpenAI- or Anthropic-specific tooling (function schemas, system prompt behavior, safety guardrail consistency)

Accessing V4-Pro

DeepSeek V4-Pro is available:

  1. Direct via DeepSeek API — api-docs.deepseek.com — requires a DeepSeek account
  2. Via OpenRouter — lists DeepSeek models alongside all major providers, useful if you want a single API routing layer

If you’re using OpenRouter, check that the routing is hitting V4-Pro specifically (not DeepSeek-V3 or earlier models) to capture the discounted pricing.

The Bigger Picture

Every few months, DeepSeek does something that resets expectations about what AI inference should cost. This is now a pattern, not an anomaly.

For independent developers and small teams running agentic applications, the cost curve on frontier-class AI has dropped by roughly an order of magnitude in 18 months. V4-Pro at 75% off is effectively a professional-grade model available for the cost of a coffee per million tokens.

The discount expires May 5. The permanent cache-hit reduction doesn’t.
