Signal Processing Transformer

Closed weights Softbank September 2025

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 the numbers mean

Background

Signal Processing Transformer was published by Softbank, in Japan, in September 2025. The organisation is categorised as industry.

It works in Other, and is recorded as doing signal processing.

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

Answers

Signal Processing Transformer — common questions

01

What GPU do I need to run Signal Processing Transformer?

None. Signal Processing Transformer 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.

02

Is Signal Processing Transformer open source?

No. Signal Processing Transformer has not had its weights published, so it exists only as a service controlled by its owner.

03

How many parameters does Signal Processing Transformer have?

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

04

Who created Signal Processing Transformer?

Signal Processing Transformer was published by Softbank, based in Japan, categorised as industry.

05

When was Signal Processing Transformer released?

Signal Processing Transformer was published in September 2025.

06

What is Signal Processing Transformer used for?

Signal Processing Transformer works in Other, and is recorded as handling signal processing. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

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.
