Odyssey 12B
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
Odyssey 12B was published by Anthrogen, in the country recorded as United States of America, during October 2025. The category the publisher falls under is industry.
It works in the domain of Biology, and is recorded as performing the task of 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
Odyssey 12B— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
Odyssey 12B— how many parameters does it have?
It has a parameter count of 12B. 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.
Odyssey 12B— who created it?
It was published by Anthrogen, based in United States of America, an organisation categorised as industry.
Odyssey 12B— when was it released?
It was published in October 2025.
Odyssey 12B— what is it used for?
It works in the domain of Biology, and is recorded as handling the task of 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.
Odyssey 12B— what GPU do I need to run it?
None. This 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.
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.
