DDPM
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.
- Training data
- 9,541,304 tokens
TCGA: 6,499 × 978 = 6,356,022 GTEx: 9,796 × 974 = 9,541,304 Total: 6,356,022 + 9,541,304 = 15,897,326 ≈ 1.6e7 datapoints
Training compute
The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

- Hardware
1. Hardware setup: 1x NVIDIA A40 GPU (1.50×10¹⁴ FLOP/s per GPU) 2. Training duration: 15,000 seconds (directly provided - sum of TCGA training: 3,780s and GTEx training: 11,220s) 3. Utilization rate: 40% 4. Calculation: 1.50×10¹⁴ FLOP/s × 1 GPU × 15,000s × 0.4 = 9.0×10¹⁷ FLOPs
The training run
What it physically took to train: which chips, how many, for how long, and what that drew from the wall.

What the numbers mean
Where it came from
DDPM was published by University Paris-Saclay,Radboud University Medical Center, in France, in April 2024. It comes out of academia,Academia.
It works in Biology, and is recorded as doing gene expression profile generation.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
How it was trained
Producing it required around 9 × 10¹⁷ FLOP of arithmetic, on NVIDIA A40 PCIe, which is a statement about the training budget rather than about inference.
Around 9,541,304 tokens went into training it.
Answers
DDPM — common questions
How many parameters does DDPM have?
No parameter count has been published for DDPM, which is why no memory or speed figure appears on this page.
Who created DDPM?
DDPM was published by University Paris-Saclay,Radboud University Medical Center, based in France, categorised as academia,Academia.
When was DDPM released?
DDPM was published in April 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is DDPM used for?
DDPM works in Biology, and is recorded as handling gene expression profile generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
How much compute was used to train DDPM?
Around 9 × 10¹⁷ FLOP, on NVIDIA A40 PCIe. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.
What GPU do I need to run DDPM?
None. DDPM is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Is DDPM open source?
The licensing for DDPM was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
