Notes

2026-09-22 PRICES CORRECTED to the current published rates. Input $0.22 -> $0.15, Output $0.66 -> $0.60, Cache Read $0.007 -> $0.003 (all OFF-PEAK, consistent with this row's existing off-peak convention). This row was flagged inconclusive on 2026-09-14 and again on 2026-09-21 while the calculator quoted an input price 47% above the published rate. Holding a third week would not have produced better evidence, so the numbers are being corrected now and the naming question separated out. EVIDENCE: three named sources published under the V4 Flash name itself (v4flash.com/pricing, devtk.ai/en/models/deepseek-v4-flash/, deepseek.ai/pricing) give off-peak $0.15 input / $0.003 cache-hit / $0.60 output, peak $0.30 / $0.006 / $1.20, with the same 1M context and 384K max output already stored here. Stable across two consecutive weekly runs. This clears the two-independent-named-sources bar. OPEN NAMING QUESTION — NOT RESOLVED BY THIS EDIT: provider-wide searches label these same rates 'DeepSeek V4.1 Flash', while pages titled for V4 Flash carry them too. The numbers are corroborated; only the SKU label is ambiguous. The row keeps the name 'DeepSeek V4 Flash' because renaming a tracked product is an editorial call. FOR KHALED: if DeepSeek's current SKU is named V4.1 Flash, rename this row. The prices are correct either way. PEAK/OFF-PEAK: DeepSeek runs a time-of-day schedule (peak 01:00-04:00 and 06:00-10:00 UTC). Schema has no peak dimension, so off-peak is stored as it covers 17 of 24 hours. Peak rates are 2x. [2026-09-28] Verification attempt produced no clear result — recheck next run. NOTE: DeepSeek's own docs site (api-docs.deepseek.com/news/) published an item titled "DeepSeek-V4.1-Flash: Smarter, Faster, More Efficient," and OpenRouter/llm-stats now list a dedicated "DeepSeek V4.1 Flash" model page — this reinforces the open naming question above. No digit-level content was retrievable this run to confirm whether rates changed alongside the rename. [2026-10-10] Verification attempt produced no clear result — recheck next run. cloudzero and zenmux (citing DeepSeek's official page) give $0.14 input / $0.28 output / $0.0028 cache-hit for V4 Flash — output less than half the stored $0.60. anotherwrapper lists a V4-Flash-0423 SKU at $0.10/$0.20. Unclear whether these are original V4 Flash launch rates vs the V4.1 Flash rates stored here. Prices LEFT at $0.15/$0.60/$0.003. ACTION FOR KHALED: read api-docs.deepseek.com/quick_start/pricing and resolve SKU + rates together. [2026-10-11] Verification attempt produced no clear result — recheck next run. Stored off-peak rates ($0.15 / $0.60 / $0.003 cache-hit; peak $0.30 / $1.20 / $0.006) match current DeepSeek V4.1 Flash (served as 'deepseek-flash' since 2026-09-10) per benchlm + costgoat Oct 2026 tables. Sources also report the original 'DeepSeek V4 Flash 0731' (deepseek-v4-flash) was RETIRED 2026-09-10, and describe the $0.14/$0.28 figures as pre-August flat pricing (outdated). Prices LEFT unchanged. ACTION FOR KHALED: rename this row to 'DeepSeek V4.1 Flash' (prices already correct), or mark V4 Flash Retired and add V4.1 Flash as a new row.
