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 the numbers mean

Background

Odyssey 12B was published by Anthrogen, in United States of America, in October 2025. industry is the category the publisher falls under.

It works in Biology, and is recorded as doing protein or nucleotide language model (pLM/nLM), Protein generation.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

Answers

Odyssey 12B — common questions

01

Is Odyssey 12B open source?

No. Odyssey 12B has not had its weights published, so it exists only as a service controlled by its owner.

02

How many parameters does Odyssey 12B have?

Odyssey 12B has 12B parameters. 12B. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

03

Who created Odyssey 12B?

Odyssey 12B was published by Anthrogen, based in United States of America, categorised as industry.

04

When was Odyssey 12B released?

Odyssey 12B was published in October 2025.

05

What is Odyssey 12B used for?

Odyssey 12B works in Biology, and is recorded as handling protein or nucleotide language model (pLM/nLM), Protein generation. 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 Odyssey 12B?

None. Odyssey 12B 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.
