CICERO

Open weights Meta AI November 2022

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.

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

"We obtained a dataset of 125,261 games of Diplomacy played online at webDiplomacy.net. Of these, 40,408 games contained dialogue, with a total of 12,901,662 messages exchanged between players. Player accounts were de-identified and automated redaction of personally identifiable information (PII) was performed by webDiplomacy. We refer to this dataset hereafter as WebDiplomacy ."

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

Background

CICERO was published by Meta AI, in United States of America, in November 2022. It comes out of industry.

It works in Games, and is recorded as doing diplomacy.

The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold.

Training and provenance

It is tracked in the underlying dataset for one reason in particular: sOTA improvement.

Answers

CICERO — common questions

01

What GPU do I need to run CICERO?

We cannot say. CICERO 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.

02

Is CICERO open source?

Its weights are published, so CICERO 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.

03

How many parameters does CICERO have?

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

04

Who created CICERO?

CICERO was published by Meta AI, based in United States of America, categorised as industry.

05

When was CICERO released?

CICERO was published in November 2022. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

06

What is CICERO used for?

CICERO works in Games, and is recorded as handling diplomacy. These are the areas it was designed around; they describe intent rather than a hard boundary.

07

Where can I download CICERO?

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

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.
