Cogito 1 series

Open weights April 2025

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
Language

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

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.

What the numbers mean

What this model is

Cogito 1 series was published by its authors, in April 2025.

It works in Language.

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.

Answers

Cogito 1 series — common questions

01

How many parameters does Cogito 1 series have?

No parameter count has been published for Cogito 1 series, which is why no memory or speed figure appears on this page.

02

When was Cogito 1 series released?

Cogito 1 series was published in April 2025.

03

What is Cogito 1 series used for?

Cogito 1 series works in Language. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

04

Where can I download Cogito 1 series?

The weights for Cogito 1 series are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

05

What GPU do I need to run Cogito 1 series?

We cannot say. Cogito 1 series 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.

06

Is Cogito 1 series open source?

Its weights are published, so Cogito 1 series 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.

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.
