YOLOv8 (reCAPTCHA fine-tuned)

Closed weights ETH Zurich September 2024

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.

What it does

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

Domain
Vision
Task
Image classification, Image segmentation
Base model
YOLOv8x

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

Combined with the public data, this resulted in around 14k image/label pairs for fine-tuning the classification model.

Availability

Whether you can obtain the model and run it on your own hardware, which is what decides if any of the graphics-card figures on this page apply.

Training code

What the numbers mean

Where it came from

YOLOv8 (reCAPTCHA fine-tuned) was published by ETH Zurich, in Switzerland, in September 2024. academia is the category the publisher falls under.

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

Its starting point was YOLOv8x — most models at this scale are adapted from an existing base rather than built from nothing.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Answers

YOLOv8 (reCAPTCHA fine-tuned) — common questions

01

Is YOLOv8 (reCAPTCHA fine-tuned) open source?

The licensing for YOLOv8 (reCAPTCHA fine-tuned) was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

02

How many parameters does YOLOv8 (reCAPTCHA fine-tuned) have?

No parameter count has been published for YOLOv8 (reCAPTCHA fine-tuned), which is why no memory or speed figure appears on this page.

03

Who created YOLOv8 (reCAPTCHA fine-tuned)?

YOLOv8 (reCAPTCHA fine-tuned) was published by ETH Zurich, based in Switzerland, categorised as academia.

04

When was YOLOv8 (reCAPTCHA fine-tuned) released?

YOLOv8 (reCAPTCHA fine-tuned) was published in September 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.

05

What is YOLOv8 (reCAPTCHA fine-tuned) used for?

YOLOv8 (reCAPTCHA fine-tuned) works in Vision, and is recorded as handling image classification, Image segmentation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

What GPU do I need to run YOLOv8 (reCAPTCHA fine-tuned)?

None. YOLOv8 (reCAPTCHA fine-tuned) 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.
