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 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
1 × 10¹⁹ FLOP

1. Hardware setup: 1x NVIDIA GeForce RTX 3090 (1.60 × 10¹⁴ FLOP/s) 2. Training duration: Estimated based on dataset size and batch processing - 71,861,060 total samples (3,593,053 samples × 20 epochs) - 561,719 batches (batch size 128) - ~15.6 hours (56,172 seconds) 3. Utilization rate: 40% 4. Final calculation: 1.60 × 10¹⁴ FLOP/s × 1 GPU × 5.6 × 10⁴ s × 0.4 = 3.6 × 10¹⁸ FLOPs (Rounded to 1.0 × 10¹⁹ FLOPs)

What the numbers mean

Where it came from

DeepSA was published by ShanghaiTech University, in the country recorded as China, during November 2023. It comes out of an organisation categorised as academia.

It works in the domain of Biology, and is recorded as performing the task of synthetic accessibility model.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

What went into building it

The training run consumed about 1 × 10¹⁹ FLOP, on hardware recorded as NVIDIA GeForce RTX 3090. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Answers

DeepSA — common questions

01

DeepSA— when was it released?

It was published in November 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

02

DeepSA— what is it used for?

It works in the domain of Biology, and is recorded as handling the task of synthetic accessibility model. These are the areas it was designed around; they describe intent rather than a hard boundary.

03

DeepSA— how much compute was used to train it?

Training consumed around 1 × 10¹⁹ FLOP, on hardware recorded as NVIDIA GeForce RTX 3090. 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

DeepSA— what GPU do I need to run it?

None. This 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.

05

DeepSA— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

06

DeepSA— how many parameters does it have?

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

07

DeepSA— who created it?

It was published by ShanghaiTech University, based in China, an organisation categorised as academia.

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.
