Odyssey 1.2B
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
Where it came from
Odyssey 1.2B 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.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
Odyssey 1.2B — common questions
How many parameters does Odyssey 1.2B have?
Odyssey 1.2B has 1.2B parameters. 1.2B. 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.
Who created Odyssey 1.2B?
Odyssey 1.2B was published by Anthrogen, based in United States of America, categorised as industry.
When was Odyssey 1.2B released?
Odyssey 1.2B was published in October 2025.
What is Odyssey 1.2B used for?
Odyssey 1.2B works in Biology, and is recorded as handling protein or nucleotide language model (pLM/nLM), Protein generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
What GPU do I need to run Odyssey 1.2B?
None. Odyssey 1.2B 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.
Is Odyssey 1.2B open source?
No. Odyssey 1.2B has not had its weights published, so it exists only as a service controlled by its owner.
