In short
- DeepSeek quietly swapped deepseek-v4-pro to the 0813 construct, the general-availability launch of a mannequin that had been operating as a preview since April.
- Throughout 9 agent benchmarks the place each fashions are scored, DeepSeek’s desk places Claude Fable 5 forward by a median of 5.3%. On two of them, DeepSeek wins.
- Fable 5 prices $10 per million enter tokens and $50 per million output. V4 Professional prices $0.435 and $0.87.
DeepSeek shipped the completed model of its flagship on Wednesday with no weblog publish and no announcement. The inform was a desk cell: the mannequin model listed for “deepseek-v4-pro” on the API pricing page now reads DeepSeek-V4-Professional-0813.
The fee to make use of this mannequin is round $0.435 and $0.87 per million tokens (the fundamental unit of data a mannequin can deal with) of enter and output. So the pricing construction stays the identical, however what modified is the weights beneath.
Deepseek V4 Professional has been within the wild since April, priced 98% below GPT-5 Pro, and each impartial lab that examined it was testing a preview. DeepSeek mentioned so itself on July 31, when it pushed V4-Flash to common availability and famous that the Professional API was “unchanged” with the official launch to “comply with quickly.” The mannequin card on Hugging Face, the go-to repository for open-source AI initiatives, nonetheless describes the V4 collection as “a preview model.”
So the broadly circulated scores describe a construct DeepSeek thought of unfinished. No one exterior the corporate has independently benchmarked 0813 but.
What DeepSeek’s desk claims
The corporate printed a comparability throughout 10 agent benchmarks. On the eight the place Fable 5 or one other mannequin has the benefit, the gaps are small.
Common Fable 5’s relative lead throughout the benchmarks and also you get 5.3%. Strip out Humanity’s Final Examination with out instruments—the place DeepSeek scores 42.7 in opposition to 53.3, a ten.6% hole that skews all the pieces—and the remaining rows common 2.8%.
Pricing is public on each side, and that is the place the comparability stops being shut. Fable 5 runs $10 per million enter tokens and $50 per million output. V4 Professional runs $0.435 and $0.87, with cached enter at $0.003625. On blended charges that’s $30 in opposition to $0.65—roughly 46 occasions, or 4,600% of the associated fee. That’s the form of unfold that issues while you’re operating a enterprise and utilizing AI instruments at scale.
Price per accomplished job runs wider, as a result of Fable 5 thinks longer and writes extra. Synthetic Evaluation measured it at $3.15 per benchmark job in opposition to 3 cents for V4-Flash, about 105 times cheaper. Hugging Face CEO Clément Delangue put the spread at over $31 per task in opposition to roughly $0.04. No per-task determine exists for 0813 but.
Anthropic’s personal lineup complicates the premium. Claude Opus 5 outscores Fable 5 on most benchmarks at half the price.
DeepSeek scored these itself, on infrastructure it hasn’t launched. Its July word specified DeepSeek Harness minimal mode “to be launched quickly,” operating at max effort with excessive creativity. Two of the ten benchmarks, DSBench-FullStack and DSBench-Arduous, are inner check units with no public leaderboard to examine them in opposition to.
The route of journey is constant, although. Chinese language open-weights labs maintain touchdown inside just a few factors of the American frontier at a fraction of the worth—Kimi K3 beat Fable 5 and GPT-5.6 Sol on launch, and DeepSeek and Xiaomi have been cutting frontier costs by 99% whereas U.S. labs go the opposite means. DeepSeek’s weights are MIT-licensed and on Hugging Face, so impartial verification is a obtain away.
