ResNet-200

Closed weights Microsoft Research Asia September 2016

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.

What it does

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

Domain
Vision
Task
Image classification

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
1,281,167 tokens

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
3 × 10¹⁹ FLOP

What the numbers mean

Where it came from

ResNet-200 was published by Microsoft Research Asia, in China, in September 2016. It comes out of industry.

It works in Vision, and is recorded as doing image classification.

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

Training and provenance

Training it took roughly 3 × 10¹⁹ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.

It was trained on about 1,281,167 tokens of text.

Its inclusion criterion is highly cited.

Answers

ResNet-200 — common questions

01

Is ResNet-200 open source?

No. ResNet-200 has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does ResNet-200 have?

No parameter count has been published for ResNet-200, which is why no memory or speed figure appears on this page.

03

Who created ResNet-200?

ResNet-200 was published by Microsoft Research Asia, based in China, categorised as industry.

04

When was ResNet-200 released?

ResNet-200 was published in September 2016. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

What is ResNet-200 used for?

ResNet-200 works in Vision, and is recorded as handling image classification. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

How much compute was used to train ResNet-200?

Around 3 × 10¹⁹ 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.

07

What GPU do I need to run ResNet-200?

None. ResNet-200 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.

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.
