DeepSeek Pro Latest pricing increased 56% prompt, completion reduced 58%
OpenRouter model catalogue · published 2026-09-30 04:26 UTC
CORRECTED 2026-10-02 17:58 UTC — [CORRECTION · headline] Original: “completion reduced 58%” Fact: Completion pricing increases 78.7%.
[CORRECTION · WHAT CHANGED] Original: “completion tokens from $943,718/M to $393,216/M (-58.3%).” Fact: Completion pricing is $1.9584/M to $3.50/M (+78.7%). The numbers 943,718 and 393,216 are token limits.
[CORRECTION · WHY IT MATTERS] Original: “Cost per request drops 58% for all workloads regardless of prompt-to-completion ratio” Fact: Both captured prices rise: prompt +56.25%, completion +78.7173%; a fixed-volume blend rises between those values.
[CORRECTION · triage.signals] Original: “prompt pricing increased 15.6x” Fact: Prompt price becomes 1.5625 times its old value, a 56.25% increase.
[CORRECTION · triage.triage reasoning] Original: “Pricing more than doubled” Fact: Neither captured rate doubles: prompt rises 56.25% and completion 78.7173%.

WHAT CHANGEDOpenRouter changed pricing for deepseek/deepseek-pro-latest effective 2026-09-29: prompt tokens from $0.096/M to $0.150/M (+56.3%), completion tokens from $943,718/M to $393,216/M (-58.3%). Maximum completion tokens per request reduced from 943,718 to 393,216 tokens.
WHY IT MATTERSCost per request drops 58% for all workloads regardless of prompt-to-completion ratio, but requests generating more than 393,216 completion tokens will now fail or require chunking where they previously succeeded in one call.
WHAT TO DOCheck your application's maximum completion token usage against the new 393,216 limit; if any requests exceed this, implement chunking or streaming logic before the next deployment.
