What the record says

UPDATED 2026-08-28: DeepSeek raised API prices and introduced peak/off-peak billing effective 16:00 UTC on August 16, 2026, announced alongside the V4 lineup release. Cache-miss input went from a flat $0.14 to $0.44 peak / $0.22 off-peak per 1M tokens, output from $0.28 to $1.32 / $0.66, and cache-hit input from $0.0028 to $0.014 / $0.007. Peak hours are 01:00-04:00 and 06:00-10:00 UTC, Monday to Friday, so roughly four fifths of the week bills at the off-peak rate; that share is a benchr calculation from the published hours, not a provider figure. SWE-bench Verified 79.0% is DeepSeek's provider-reported model-card figure, not an independently reproduced result. Open weights, MIT.

benchr's read

Worth it for

  • Batchable work you can schedule outside DeepSeek's peak hours, where the rate halves to one of the lowest hosted prices among models tracked by benchr — not a market-wide guarantee
  • Self-hosted at low cost
  • Volume coding tasks

Look elsewhere if

  • You need frontier-tier reasoning depth
  • Vision-first workflows
  • Your traffic is fixed to European or Asian business hours, which sit inside the peak window

Prices, limits, and identifiers above are provider facts. This section is benchr's judgement about them.
