Reference

First-party pricing references

Per-unit rates published by each model's creator on their own first-party API. Rows are source-backed references, not live quotes. Hosted-provider references (Groq, Together) render separately below where available.

Pricing is volatile and may change after retrieval. Treat prices as source-backed references, not live quotes. Prices are shown as source-backed references only. WebmasterID Models does not rank models or billing providers by price.

Hosted pricing context

Hosted pricing references

Where a third-party platform hosts the model and bills at its own rate. These rows do NOT reflect the model creator's pricing. Reference values only — not a comparison or ranking engine.

Prices are shown as source-backed references only. WebmasterID Models does not rank models or billing providers by price.

Caveats

Limitations of this comparison

  • DeepSeek v4-pro is currently running a time-limited 75% promotional discount (until 2026/05/31 15:59 UTC). The pricing rows on this page record the regular rate as the durable canonical value; the effective discounted rate is noted per row.
  • DeepSeek and Anthropic publish pricing under different unit semantics; cache pricing rows compare cache-hit input pricing on both sides.
  • WebmasterID Models does not declare a winner; readers should compare verified facts against their own workload.
