It has a parameter count of 230B. MoE. 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.
Seed 1.6— who created it?
It was published by ByteDance, based in China, an organisation categorised as industry.
Seed 1.6— when was it released?
It was published in June 2025.
Seed 1.6— what is it used for?
It works in the domain of Multimodal, Language, Vision, Video, and is recorded as handling the task of language modeling/generation, Image captioning, Video generation. These are the areas it was designed around; they describe intent rather than a hard boundary.
Seed 1.6— 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.
Seed 1.6— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
