Revision History

Cosmetic: wire two previously uncited launch-coverage references into the sentence they support, and drop the MarkTechPost entry whose explanation of the 304B figure the verification pass disproved and which is no longer cited

Correction: fix the Gemini 3.1 Pro price row against Google's published tiers, replace a Terminal-Bench comparison against GPT-5.5 that the cited model card does not contain, remove a pricing-timeline row absent from DeepSeek's change log, correct the DSec spelling, and note that the competitor benchmark columns are DeepSeek's own runs

Correction: swap the Pro and Flash pre-training token counts to match the technical report, remove an AIME 2026 score that appears in neither cited source, correct the checkpoint size to about 865 GB, correct the GPT-5.4 price row against OpenAI's published pricing, and replace the DSpark-module explanation of the 304B figure with the tensor-accounting explanation the Hugging Face data supports

Correction: rebuild the V4-Pro benchmark tables from the model card. The competitor column labelled GPT-5.5 was GPT-5.4 xHigh; its SWE-bench Verified 88.7% is not on the card, its SWE-bench Pro 58.6% was Kimi K2.6's score and its Terminal-Bench 82.7 was GPT-5.4's BrowseComp score. Two Claude Opus 4.6 cells and one MMLU-Pro cell were also wrong, and an unsourced GPT-5.2 column is replaced.

Correction: DeepSeek published open weights for DeepSeek-V4-Flash-0731 on July 31, 2026 (MIT, 48 shards, ~167 GB), so the hub no longer describes the official Flash build as API-only. Added a correctly-framed note that the V4-Pro-DSpark and V4-Flash-DSpark repositories are the same checkpoints with a speculative decoding module attached, confirmed V4-Pro is still the April preview with no official build, re-verified API pricing and the still-inactive peak/off-peak policy against DeepSeek docs, and cross-linked the new DeepSeek V4-Pro page.

Add V4-Flash and V4-Pro variants, Responses API and Codex support, and peak/off-peak API pricing
