No estimate

No hardware requirements for this model

This model's weights are open, but no parameter count has been published for it. Every memory and speed figure starts from that number, so we would rather show nothing than a fabricated estimate.

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.

What it does

The problem areas the model was built for. A model can carry several of each.

Domain

Task
Protein-ligand binding affinity prediction, Protein-ligand contact prediction

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
tokens

Data points = 16,739 training structures Note: Epochs (1000) not counted as we only consider unique data points 16,739 = 1.674e4

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.

Training compute
4 × 10²⁰ FLOP

1. Hardware setup: - Main model: 8× NVIDIA A800 GPUs (7.80×10¹³ FLOP/s per GPU) - MDN model: 4× NVIDIA Tesla V100-SXM2 GPUs (1.25×10¹⁴ FLOP/s per GPU) 2. Training duration (estimated from steps and step time): - Main model: 262,000 steps × 5s = 1.31×10⁶ seconds (~15 days) - MDN model: 65,000 steps × 5s = 3.25×10⁵ seconds (~3.76 days) 3. Utilization rate: 40% 4. Final calculation: Main: 8 GPUs × 7.80×10¹³ FLOP/s × 1.31×10⁶ s × 0.4 = 3.31×10²⁰ FLOPs MDN: 4 GPUs × 1.25×10¹⁴ FLOP/s × 3.25×10⁵ s ×…

What the numbers mean

Where it came from

DiffBindFR was published by Peking University,Tsinghua-Peiking Center for Life Sciences, in China, in April 2024. academia,Research collective is the category the publisher falls under.

It works in Biology, and is recorded as doing protein-ligand binding affinity prediction, Protein-ligand contact prediction.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all.

What went into building it

Training it took roughly 4 × 10²⁰ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.

Answers

DiffBindFR — common questions

01

What is DiffBindFR used for?

DiffBindFR works in Biology, and is recorded as handling protein-ligand binding affinity prediction, Protein-ligand contact prediction. These are the areas it was designed around; they describe intent rather than a hard boundary.

02

Where can I download DiffBindFR?

The weights for DiffBindFR are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

03

How much compute was used to train DiffBindFR?

Around 4 × 10²⁰ FLOP. 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.

04

What GPU do I need to run DiffBindFR?

We cannot say. DiffBindFR has open weights, but no parameter count has been published for it, and every memory and speed calculation starts from that number. We would rather show nothing than a fabricated estimate.

05

Is DiffBindFR open source?

Its weights are published, so DiffBindFR can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.

06

How many parameters does DiffBindFR have?

No parameter count has been published for DiffBindFR, which is why no memory or speed figure appears on this page.

07

Who created DiffBindFR?

DiffBindFR was published by Peking University,Tsinghua-Peiking Center for Life Sciences, based in China, categorised as academia,Research collective.

08

When was DiffBindFR released?

DiffBindFR 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.

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.
